FIELD OF INVENTION
[0001] This invention is related to heat exchange technology and method, specifically, an
integrated heat pipe and its heat exchange method.
BACKGROUND OF THE INVENTION
[0002] The development of LSI, mainframe computer and electrical and electronic technologies
has imposed higher requirements on the heat elimination of electronic elements and
components. For example, the integration level of CPU chips of computers has risen
by nearly 20,000 folds just within 30 years with its consumption power rising up to
a few dozen watts from its initial a few watts and with the resulting heat flux being
up to 100W/cm
2 in some cases. The working reliability and life of computer is closely related to
its working temperature and the required maximum temperature (internal) of chips ≤130°C
and the required surface temperature ≤80°C. However, its working reliability will
decrease by 3.8% whenever the temperature of chip rises by 1°C, and its life will
increase by' 50% whenever the temperature of chip decreases by 10%. High speed and
high integration level imposes very high requirement on the uniformity of the temperature
of chips. Therefore, heat elimination has become a major problem that has to be resolved
in the course of research and development of electronic products and it is directly
related to the property, reliability and cost of electronic products.
[0003] Initially, there were several heat elimination technologies for chips, such as heat
elimination fan, heat elimination plate, pre-made heat elimination holes, keyboard
convection heat elimination, water cooling heat elimination, etc. Though their cost
was low, their heat eliminating effect was not so good and their reliability was low,
therefore, they were not able to meet the requirement of the development of computer.
[0004] The State Laboratory of Sandia in the USA first applied heat pipe technology in the
heat elimination of computer chips, which produced fairly good heat elimination effect.
[0005] Heat pipe technology is a highly effective heat transfer element and highly effective
heat transfer technology, which transfers heat by the phase change process, that is,
to fill a small amount of liquid medium into the enclosed vacuum chamber of a tubular
article, where a liquid medium is used to absorb heat, vaporizes, condenses and eliminates
heat. Heat pipe heat exchanger is so constructed that the heat absorption end and
heat elimination end of several heat pipe elements are partitioned and the heat absorption
end and heat elimination end are surrounded with articles to form two shaped cavities,
heat absorption and heat elimination, with hot fluid flowing through the heat absorption
chamber and the cold fluid flowing through the heat elimination chamber, thus heat
being transferred to the cold fluid via heat pipe and the phase change of the heat
pipe medium. The structural characteristic of heat pipe is that the inner chamber
of a flexible tubular article is vacuumed and filled with a small amount of liquid
medium and the inner chamber of the pipe is just big enough for a liquid absorption
cartridge that ensures liquid reflux. A single heat pipe can be used as heat exchanger,
but it is more often that the heat exchangers composed of several heat pipe elements
are used at the same time.
[0006] However, the current heat pipe technology of the heat elimination of plane heat sources,
such as computer chips and other electrical and electronic elements and components
is mostly of studded heat pipe type. That is to make notch in the metal plate of fine
thermal conductivity, inlay the heat absorption end of heat pipe in the notch, put
the heat elimination end at a ventilated place and the metal plate is placed horizontally
above the heating element. In order to ensure that the heat source plane is in full
contact with the metal plane and electrically insulated, a heat conducting insulation
plate coated with heat conducting silicone is placed between them. Heat is transferred
via heat conducting silicone, heat conducting insulating plate from the heat source
to the metal plate, then to the heat pipe, where as a result of phase change heat
is transferred from heat absorption end to the condensation end, and the heat absorbed
at the condensation end is transferred through the shell of the heat pipe to another
layer of silicone, then to the aluminum fin type radiator. The heat accumulated in
the fin radiator is carried away by forced cold wind to accomplish the purpose of
reducing the temperature of the heat source ultimately. This inlaying method does
not produce very good heat elimination effect as the contact thermal resistance of
the element connected with interface in the course of heat transfer is so big that
the heat pipe cannot play the role of high efficiency heat transfer and the heat eliminating
effect is not so good. In addition, through by welding the heat absorption end of
one or several heat pipes on the metal plate and installing a number of fin groups
to support heat elimination at the heat elimination end of heat pipe, the contact
thermal resistance of the interface can be reduced, the medium of the heat pipe can
not be in full contact with the heat source and can not produce very good heat transfer
effect.
[0007] In the metal foundry Industry, in order to ensure that the alloy melt solidifies
immediately in. the casting mould and cools down the mould within shortest time to
increase the production efficiency of casting moulds, some people insert the heat
absorption ends of many heat pipes into the main body of the hard mould to take advantage
of the inherent axial heat transfer characteristic of conventional heat pipe in hard
mould foundry and in ejection molding and insert the heat elimination end of heat
pipe into water cooling pipe so as to level the temperature gradient in the hard mould
by heat pipe and to conspicuously improve the heat transfer efficiency of the casting
mould without increasing water consumption. What merits attention is the application
of heat pipe technology in foundry Industry includes the newest continuous casting
and continuous rolling processes, such as wheel rolling and wheel casting and continuous
crystallizing that require heat exchanging. Up to now, no structure other than the
conventional heat pipe and any new heat transfer mode have been found. However, because
of the interface thermal resistance between the casting mould and the wall of heat
pipe and the limitations of the structure it is impossible for the original structure
to meet the even higher cooling speed requirement of alloy including fast solidifying
alloy on the mould and it is more so of certain special and higher requirement.
[0008] The fast solidifying metal technology is to fix metal molecules on higher energy
level. Since Duwez invented the fast solidifying technology in 1960, the technology
has been improved and systemized continuously and commercialized gradually. Because
of its high dynamic property and fine physical and chemical property the fast solidifying
metals have attracted the attention of the materials scientific workers throughout
the world, who have put much manpower, material and funds in the research. As a result
of the development over the last three decades the fast solidification technology
and its research on metals have become one of the important branches of materials
science and engineering. As the fast solidification technology is to increase the
super-cooling extent and speed of solidification mainly by increasing solidification
speed, the solidification speed is very important for the formation and property of
the fast solidifying material.
[0009] At present, there are dozens of fast solidification processes and equipment for production
of fast solidifying materials, mainly in three categories of mould cooling technology,
atomization technology and surface melting and sedimentation technology. According
to the basic principle of fast solidification for melt dispersion and thermal resistance
reduction the existing production unit includes rotating or fixed cold mould (or base),
mostly made from metals of fine thermal conductivity. Its heat exchange method is
to build a cooling liquid passage in fabrication of the equipment base, which is designed
to carry away swiftly the heat absorbed by the base to accomplish the fast cooling
purpose of fast solidifying material. Because of the limitations of the traditional
heat transfer mode and the structure of the base the contact area between base and
cooling liquid is small (normally, the area of the heat absorption end is always bigger
that that of the heat elimination end) and contact thermal resistance is big, it is
difficult for the cooling liquid to carry away the large amount of heat emitted by
the melt during the solidification process instantly. Therefore, it is very difficult
to improve and balance the distribution of temperature field so as to further increase
the heat transfer speed during the solidification process. Moreover, as the temperature
at the heat balance spot of the base is fairly high during operation, the capacity
of the production unit declines, its life gets shorter, its efficiency gets lower
and the quality deteriorates. Up to now there is no report about any application of
heat pipe technology in the field of fast solidification technology.
[0010] Hot fluid ejecting nozzles are widely applied in engineering technology, particularly,
plasma welding cutting torch, plasma spray coating nozzle, nozzle of electron beam
welding torch, nozzle of large power arc welding torch, etc. As the high temperature
heat flux flows through nozzle for such a long time during operation that the nozzle
is easily damaged, people tend to manufacture nozzles with metals of fine thermal
conductivity and some even cool nozzles with water. Notwithstanding all this, the
effect is not so good and the life does not get any longer and the cooling water leakage
may damage the electrical insulation of the equipment greatly reducing the reliability
of the equipment. Although some people use heat pipe technology in nozzles, the high
efficiency heat transfer characteristic of heat pipe can not be displayed because
their technical design fails to greatly improve the heat elimination area of nozzle
and the geometric dimensions of nozzle are small. Therefore, the existing technology
is still unable to meet the requirement of the engineering technology and should be
further improved.
[0011] Heat exchanger, including that for heat exchange between fluid media is the most
conventional basic equipment used in various Industrial sectors of the state economy.
People have never stopped in trying to improve the function of heat exchanger to increase
the heat transfer efficiency of heat exchanger by various technologies, methods and
means over hundreds of years. The heat pipe phase change heat transfer technology,
including the use of high heat conductivity medium to transfer heat, is an effective
try. The high thermal conductivity, big heat elimination area and fairly low production
cost of heat pipe heat exchanger is well applied in residual heat recovery in the
field of heat exchanger. Nevertheless, the branch like distribution of the heat pipe
of the traditional heat pipe heat exchanger and its square box structure is apt to
fouling on heat elimination surface and dead comer and whirlpool of fluid flow thus
affecting the normal heat exchange and application life of heat exchanger. The single
structure and huge volume of the traditional heat exchanger is one of the limiting
factors. Up to now there is no report about any application of integrated heat pipe
technology in the field of heat exchanger.
[0012] Large electric motor, generator and engine are the power source of the modem Industry,
the mainstay for the existence of modem technology and the basic equipment of the
state economy. Their common structural characteristic is that they all have a turning
shaft-rotor that requires heat elimination any time. If the heat including that emitted
inside the rotor cannot be eliminated, overheating might happen reducing the power,
abating the insulation and damaging electrical and mechanical equipment, or even leading
to the loss of working capacity of equipment. Generally speaking, for every degree
of temperature rises above the upper limit of the motor, its life span is reduced
by half. In order to eliminate heat from rotor the large capacity motor and generator
are normally cooled with the gas in enclosed re-circulation, or by pipe ventilation,
independent fan type cooling or by having hollow copper winding of rotor for cooling
water flowing through the hollow copper winding, shaft and sealed water jacket to
carry away the heat. Some people apply the heat pipe phase change heat transfer technology
to improve the heat elimination of motor rotor in this manner that they hollow out
the shaft of the motor so as to form a somewhat biased empty chamber, which extends
through the heat absorption end and heat elimination end of rotor and is vacuumed
and filled with a small amount of liquid medium. The medium absorbs heat and vaporizes
at the heat absorption end and emits heat and condenses into liquid at the heat elimination
end. The reflux liquid flows back to the heat absorption end over the slope under
the action of a centrifugal force. The heat carried by the medium at the heat elimination
end is carried away by the cold air blowing out of the fan and the internal heat in
the rotor is ultimately eliminated thus forming a reciprocating heat recycle. The
rotating heat pipe technology can produce fairly good effect in improving the heat
elimination of motor rotor. However, the above-mentioned methods have many shortcomings,
such as inferior heat elimination and high production cost and still they have a common
shortcoming, that is, heat elimination area is small and the heat elimination capacity
is intrinsically inadequate. How to improve the beat elimination capacity of motor
rotor and to enhance the capacity and reliability of the above-mentioned power machines
has been a subject that the scientists and engineers have to confront for a long time.
[0013] As described above, the existing heat pipe, heat pipe heat exchanger and heat pipe
heat exchange technology, initially applied in home appliances, have found more and
more applications in high tech spheres such as aviation and space Industries as a
result of their development over last 50 years or so because of simple structure,
reliability, high heat thermal conductivity and easy realization and they are being
used in more and more areas. Some new heat pipe structures and new heat transfer mechanisms
came into being over recent years, but up to now the method for increasing the heat
elimination area of heat pipe of heat exchange technology is mostly to increase the
absolute length of the heat elimination end of heat pipe, install auxiliary heat elimination
ribbed plates and increase the number of heat pipes; the structure of heat pipe heat
exchanger is still single; the structure of the heat absorption end of heat pipe and
heat pipe radiator is still short of any variation. All these have greatly limited
the application and popularization of heat pipe and heat pipe technology. Particularly,
as to how to reduce thermal resistance of contact heat source apart from the heat
flux to increase heat transfer efficiency, it is difficult for the existing heat pipe
heat exchange technology to display its merit fully because of its unique structure.
For the heat elimination for a narrow space, special geometric shape and large heat
flux density and the heat elimination for the large heat flux density during intermittent
interval and the limited cold source conditions, it is imperative to improve the existing
heat pipe technology.

chamber, which runs through the two opposite ends of shell. The cross section of its
heat absorption chamber can be circular, rectangular, polygon, dentiform or other
geometric shape with a slope for mould pulling. Heat containing structures of fine
thermal conductivity, large thermal capacity and large surface area are used as heat
carriers of the heat elimination end of heat pipe and placed outside the enclosed
chamber or inside it or outside and inside it, and the structure of thermal container
can be film-shaped or flake-shaped or tubular or silk-shaped materials of large surface
area or their combination in curled or stacked form, or thin-wall covered or in their
combined form. There is a distance between layers enough for full heat transfer by
heat transfer medium; the opening between layers faces the heat transfer medium of
heat absorption end. When liquid medium is used in the said integrated heat pipe,
the cross section of its heat absorption chamber that is connected with vacuum chamber
can have groove or liquid absorbing cartridge or sintered metal powder or other effective
liquid absorbing cartridge structures.
[0039] When this heat pipe is used for heat elimination of cold mould made of fast solidifying
metal block, a heat absorption end of heat pipe and another high thermal conductivity
metal made template can be made opposite each other with a high thermal conductivity
metal template placed between them. The template is hollow and has metal fluid casting
channel and gas releasing channel in it. The heat absorption ends of heat pipe and
the template surround the hollow part and turn it into a heat absorption chamber.
Heat containing structures of fine thermal conductivity, large thermal capacity and
large surface area are used as heat carriers of the heat elimination end of heat pipe
and placed outside the enclosed chamber or inside it or outside and inside it, the
structure of thermal container can be film-shaped or flake-shaped or tubular or silk-shaped
materials of large surface area or their combination in curled or stacked form; the
structure of its heat container can be bee-hive shaped, floccular, hemp-like, film
or sheet formed in spirals or stacked, thin-wall tube covered or their combined form.
There is a distance between layers enough for full heat transfer by heat transfer

end. When liquid medium is used in the said integrated heat pipe, the corresponding
wall surface of heat absorption end in enclosed vacuum chamber can have liquid absorbing
cartridge structures such as groove or sintered metal powder or other effective liquid

[0040] When this heat pipe is used as heat exchanger between two kinds of fluid media, several
groups of heat absorbing cavities as the heat absorption end of heat pipe run through
the two opposite ends of shell and are placed in the middle of heat pipe. The cross
section of its heat absorption chamber can be circular, rectangular, polygon, dentiform
or other geometric shape and their combination. The thin-wall fluid passage structure
at the heat elimination end of heat pipe can be corrugated, radial and upright fin
shaped or radial and bended fin shaped curved shape, placed outside enclosed chamber
and parallel to the axial line of heat absorption chamber. When liquid medium is used
in the integrated heat pipe, the surface of the heat absorption chamber connected
with vacuum chamber can has such liquid absorbing cartridge structures as groove or
sintered metal powder or other effective liquid absorbing cartridge structure. A liquid
medium accumulation basin can be placed under the liquid absorbing cartridge. Heat
absorption chamber, the corrugated thin-wall fluid passage placed outside enclosed
chamber and the end cover of shell vertical to the heat absorption chamber together
form the enclosed chamber of heat pipe. The auxiliary hot fluid passage that covers
the two ends of the end cover of shell and has hot (and cold) fluid inlet and outlet
and the auxiliary cold fluid passage that covers the corrugated thin-wall fluid passage
outside enclosed chamber and has cold (and hot) fluid inlet and outlet and the heat
pipe together constitute the integrated heat pipe heat exchanger for heat exchange
between two fluid media.
[0041] A method includes obtaining large heat elimination area in a small volume with an
integrated heat pipe of a complicated shape surface and radial structure mainly for
contact heat source and fluid medium heat source.
[0042] This method is designed to obtain a compact space by taking advantage of the corrugated
thin-wall fluid passage placed outside enclosed chamber or inside it or outside and
inside it or the enclosed tubular thin-wall fluid passage or thermal container of
fine thermal conductivity, large thermal capacity and large surface area or the heat
carrier of any of their combination; and to obtain larger heat elimination area by
taking advantage of the corrugated curved surface of the heat carrier.
[0043] A method for setting the structure of the heat absorption end of integrated heat
pipe, including distribution of heat transfer medium somewhere in the enclosed chamber
closest to the heat absorption surface. When a liquid medium is used, a liquid absorbing
cartridge structure of heat pipe can be placed some where in the enclosed chamber
closest to the heat-absorbing surface.
[0044] According to this method, when the heat absorption end of heat pipe is an end surface
or part of the end surface vertical to the axial line of heat pipe, the shaped surface
of its heat absorption end can be so made as to correspond, tally and closely match
with the outline surface of heat source. It can be made smooth, flat and straight;
smooth and raised; smooth and sunken; it can be made according to the outline curved
surface of contact heat source, or inlaid and covered and fully and closely matched.
[0045] This method is so designed that when the heat absorption end of heat pipe is one
or more than one groups of heat absorption cavities that run through shell and enclosed
chamber, the heat absorption chamber structure can be that running through the two
opposite ends of shell, or that running through two neighboring ends of shell or that
running through the same end of shell. The cross section of its heat absorption chamber
can be circular, rectangular, polygon, dentiform or other geometric shape. The vertical
section of its heat absorption chamber can be of a slope.
[0046] This method includes that the heat absorption end of heat pipe is so made that the
outline surface of its cross section is circular and covers the revolving shell of
enclosed chamber. The outline surface of its vertical section is rectangular, drum-shaped
or other revolving shape that meets the requirement of heat source.
[0047] This method includes that the heat absorption end of heat pipe can be so made that
the outline surface of its cross section is enclosed corrugated thin-wall curved surface
that is based on circular or other geometric shape and covers enclosed chamber, they
can be more than three groups of evenly distributed or unevenly distributed, contour
or non-contour fin-shaped curved surfaces, which can be radial and upright fin shaped,
radial and bended fin-shaped or other suitable curved surface and their combination.
The vertical section of its basic outline surface is rectangular, drum-shaped or other
revolving shape surface that meets the requirement of heat source.
[0048] This method includes that a hollow high thermal conductivity metal template that
has hot melt pouring channel and gas releasing channel and is placed between the heat
absorption end of heat pipe and another high thermal conductivity metal template,
can also obtain the heat absorption chamber of integrated heat pipe and the high thermal
conductivity metal template that is made hollow in the center and has hot melt pouring
channel and gas releasing channel and placed between the heat absorption end surfaces
of two heat pipes, or the heat absorption chamber of integrated heat pipe and the
heat absorption end surface of several heat pipes form heat absorption chamber together.
[0049] A heat exchange method with integrated heat pipe. This method uses the contact heat
source on the surface of the heat absorption end of heat pipe shell to absorb heat
and transfer heat to the same heat transfer medium in the same enclosed chamber via
the wall surface of the heat absorption end of shell to enable the heat transfer medium
to absorb heat or to absorb the heat absorbed in fast dispersion of vaporization,
and use the heat carrier placed outside enclosed chamber or inside it or outside and
inside it as heat elimination end, and the heat absorbed by heat transfer medium is
contained or transferred; this method uses the low temperature fluid in the thin-wall
fluid passage placed outside enclosed chamber or inside it or outside and inside it
to transfer the heat absorbed by heat transfer medium. This method uses the thermal
container placed outside enclosed chamber or inside it or outside and inside it to
hold the heat absorbed by heat transfer medium. This method uses the heat transfer
medium of heat pipe placed somewhere in enclosed chamber closest to the heat absorption
surface and uses heat transfer medium to carry away heat to the place where heat carrier
is closest to the heat elimination surface to reduce thermal resistance, improve heat
transfer conditions and increase thermal conductivity.
[0050] A liquid medium involving method of heat exchange with rotating integrated heat pipe.
When the hot pipe is turning at a high speed, this method uses the shell of circular
cross section of heat pipe as heat absorption end surface, which absorbs heat while
turning at a high speed, and transfers heat via the wall surface of heat absorption
end of shell to the same heat medium in the same enclosed chamber that is swung on
the surface of inner wall of heat absorption end. The heat transfer medium absorbs
heat and vaporizes quickly, and the enclosed chamber is filled with saturated steam,
which is quickly condensed on the surface of thin-wall fluid passage as soon as it
meets the low temperature fluid. The hidden vaporization heat carried over is released
and the thin-wall fluid passage transfers the hidden vaporization heat to the cold
fluid outside the enclosed chamber of thin-wall fluid passage, and the heat absorbed
by heat pipe is carried away by cold fluid ultimately. The mass of the liquid medium
condensed on the surface of thin-wall fluid passage increases quickly under the centrifugal
force and the liquid medium is swung on the surface of the inner wall of heat absorption
end again thus starting a new round of heat transfer process, which repeats again
and again. This method is of a large heat elimination area, and by taking advantage
of phase change an even heat transfer can be carried out at the same temperature throughout
the whole heat elimination area. The centrifugal force of the turning heat pipe ensures
that the liquid medium flows towards the heat absorption end and the interface thermal
resistance in the course of phase change heat transfer can be reduced by a biggest
margin so that an optimum heat transfer effect is obtained.
[0051] When heat pipe is turning at a lower speed, this method uses the shell of circular
cross section of heat pipe as heat absorption end surface, which contacts the heat
source at a low turning speed to absorb heat, which is transferred to the same heat
transfer medium in the same enclosed chamber that is adhered on the inner wall surface
of heat absorption end under the adhesive action of liquid medium and is in the liquid
absorbing cartridge. The heat transfer medium absorbs heat and vaporizes quickly,
and the saturated steam filling the enclosed chamber condenses quickly on the surface
of thin-wall fluid passage as soon as it meets the low temperature fluid in the thin-wall
passage, and the hidden vaporization heat carried over is released, and the thin-wall
fluid passage transfers the hidden vaporization heat to the cold fluid outside the
enclosed chamber of thin-wall fluid passage, and the heat absorbed by heat pipe is
ultimately carried away by the cold fluid. The mass of the liquid medium condensed
on the surface of thin-wall fluid passage increases quickly under the weight action,
and it then returns to the lowest part of the enclosed chamber of heat pipe. The liquid
medium enters the liquid absorbing cartridge of heat pipe under the action of capillary
force of liquid absorbing cartridge of heat pipe, and is back again to the position
in contact with heat source, thus starting a new round of heat transfer process, which
repeats again and again. This method is of large heat elimination area and uses phase
change to carry out even heat transfer at the same temperature throughout the heat
transfer area, and the capillary force of the liquid absorbing cartridge of heat pipe
and the adhesive force of the heat pipe medium ensure that liquid medium flows toward
the heat absorption end and ideal heat transfer effect can be obtained similarly.

efficient heat transfer substances, the whole cooling surface has an even distribution
of temperature and every unit cooling area can exert its function to an utmost extent,
which is unrivalled by any other coolers with similar structure.

Application Example 6
[0075] As shown in Fig. 6, Application Example 6 is a kind of heat pipe applicable to integrated
heat pipe cold modules for producing bulk metal materials in a rapid solidification
process. No other cooling sources or additional assistant cooling device is required
for this integrated heat pipe. It can be used singly or by connecting up two pieces
together.
[0076] It is a kind of integrated heat pipe composed of a shell 6-1 with an enclosed chamber
6-2 in which a heat transfer medium 6-3 is filled. Its features is that the heat absorption
end 6-1a of the shell that is vertical to the axis of the heat pipe is built on the
outer side of the enclosed chamber 6-2, and is a plane of the heat pipe; the heat
carrier 6-4 is built in the enclosed vacuum chamber 6-2 which is enclosed by the shell
6-1 of the heat container integrated heat pipe; the heat carrier 6-4 is a heat container
6-4a made metal materials with high heat conducting coefficient and large heat capacity,
and it has large enough surface area to absorb and store heat (the heat container
6-4b is actually the hidden heat elimination end built inside the integrated heat
pipe); the heat container 6-4b is made of one group of spiral curled foil of red copper
with large surface area; each layer has enough space for the heat transfer medium
6-3 to transfer heat; the aperture between layers is set up to face the heat absorption
end; the enclosed vacuum chamber 6-2 is vacuumed and filled with heat transfer medium
6-3. The shell 6-1 and its heat absorption end 6-1a enclose the heat container 6-4b
within the enclosed chamber 6-2 which is vacuumed and filled with some heat transfer
medium6-3 to form an integrated heat pipe with a heat container.
[0077] The structure of the heat container 6-4b can be made metal foil, sheet, filament,
wire in honeycomb shape, flocculent, gunny fiber like, film, or spiral curled flake
or lapped layers, thin-wall pipe in set or even the combination of these forms.
[0078] Part of the shell 6-1 serves as the heat-in plane. In order to ensure that the heat
is transferred normally in the heat-in plane of the heat pipe, the outer rim of the
enclosed vacuum chamber 6-2 and the inner wall surface of the heat-in plane should
be embedded with the liquid absorption cartridge 6-5 when phase change of the heat
transfer medium is used to transfer heat.
[0079] Single heat pipe or double heat pipes or even multiple heat pipes integration may
be used in this invention.
[0080] When the heat pipe is used singly, a template made of materials with high heat conducting
coefficient, such as red copper, should be set between the heat absorption end of
the heat pipe and another end plate made of materials with high heat conducting coefficient,
such as red copper, and the heat absorption end, the end plate and the template should
be pieced together with bolts. On the middle of template, a hole is engraved and a
passage for melting metal and an exhaustion passage are set aside, and the heat absorption
end, the end plate and the template are engraved to form a heat chamber 6-1a. When
melting metal alloy for casting is pouring into the heat chamber 6-1a, heat can be
swiftly transferred from the heat absorption end 6-1 a of the heat pipe to the heat
transfer medium 6-3 in the enclosed vacuum chamber 6-2, where heat can be absorbed
by the heat transfer medium or swiftly diffused by the evaporation of the heat transfer
medium; and finally the heat transferred by liquid phase change or good heat-transferring
material can be diffused and absorbed swiftly through each layer of spiral curled
film or foil material with larger surface area. The melting alloy with instant release
of solidification potential energy and critical heat energy keeps the metallic structures
of liquid alloy molecule of short-range, chaos and. disorder, and finally the instant
solidification metal material of non-crystal, crystallite or quasi-crystal state,
etc. is thus obtained.
[0081] Better heat transfer efficiency can be obtained by inserting the material with high
heat conductivity coefficient (such as template made of red copper) that has an inlet
for casting and an air vent between two heat pipes. Three or more heat pipes can be
used as an integrated one.

surface of the wall of the shell 7-1 should be embedded with the liquid absorption
cartridge7-5 when phase change of the heat transfer medium is used to transfer heat.
[0084] When it works, the outer surface of the rotary cylinder shell 7-1 that serves as
the heat absorption end contacts with the heat sources and takes in heat, and then
transfers the heat to the heat transfer medium7-3 in the enclosed vacuum chamber 7-2,
where the heat is absorbed by the heat transfer medium or swiftly diffused by the
evaporation of the heat transfer medium, and then the heat can be conveyed to the
cold liquid in the liquid passage 7-4a by each group of the round section thin-wall
pipe, and finally the heat of the heat sources will be taken away by the cold liquid
to make the hot metal liquid contacting with the surface of the cylinder shell 7-1

a) The round section shell 7-1 of the heat pipe will serve as the surface of the heat
absorption end to contact heat sources and absorb heat when it rotates at a high speed,
it will transfer the heat absorbed through its wall surface of the heat absorption
end of its shell to the heat transfer medium 7-3 in the same enclosed vacuum chamber
7-2 which is thrown onto the internal wall surface of the heat absorption end by the
centrifugal force, where the heat is absorbed by the heat transfer medium7-3 and the
heat transfer medium7-3 rapidly evaporates to dispel the heat; saturated water vapor
fills the space of the enclosed vacuum chamber 7-2 and pass through the low temperature
thin-wall liquid passage 7-4 , and it condenses instantly on the surface of the thin-wall
liquid passage 7-4, the carrying evaporating heat is released there, and then the
heat is conveyed by the thin-wall liquid passage 7-4 to the cold liquid in the outer
chamber 7-4a of the thin-wall liquid passage, and finally the heat absorbed by the
heat pipe will be taken away by the cold liquid. As the condensed liquid medium on
the surface of the thin-wall liquid passage accumulates, it is thrown again on to
the internal wall surface of the heat absorption end under the centrifugal force and
a new round heat transfer begins, and in this way, it repeats continuously. This method
has large heat radiating surface, uses the phase change to realize even heat transfer
under the isothermal surface conditions. The centrifugal force of the heat pipe rotating
ensures the liquid medium flow to the heat absorption end and reduce tremendously
the heat stagnation at the interface during the heat transfer of the phase change,
thus the best heat transfer effectiveness will be acquired.
b) The round section shell 7-1 will be served as the heat absorption end to contact
heat sources and absorb heat when it rotates at low speed, it will transfer the heat
absorbed through its wall surface of the heat absorption end of its shell to the heat
transfer liquid medium 7-3 within the same enclosed vacuum chamber 7-2 which will
adhere onto the internal wall surface of the heat pipe liquid absorption cartridge
7-5 by the cohesive force, there heat can be absorbed by the heat transfer medium7-3
and rapid evaporate to dispel the heat. Saturated water vapor fills the space of the
enclosed vacuum chamber 7-2 and pass through the low temperature thin-wall liquid
passage 7-4, and it condenses instantly on the surface of the thin-wall liquid passage
7-4, the carrying evaporating heat is released there, and then the heat is conveyed
by the thin-wall liquid passage 7-4 to the cold liquid outside the closed chamber
7-4a of the thin-wall liquid passage, and finally the heat of the heat pipe will be
taken away by the cold liquid. As the condensed liquid medium on the surface of the
thin-wall liquid passage accumulates, it returns again to the lowest position of the
enclosed chamber 7-2 of the heat pipe under its own gravity, the liquid medium 7-3
will run into the heat pipe liquid absorption cartridge under the capillary force
and it is brought again to the position where it can contact the heat sources, thus
a new round heat transfer begins, and in this way, it repeats continuously. This method
has large heat radiating surface, uses the phase change to realize even heat transfer
under the isothermal surface conditions. The capillary force of the heat pipe liquid
absorption cartridge and the adhesive force of the liquid medium of the heat pipe
ensures the liquid medium flow to the heat absorption end, thus the best heat transfer
