[Technical Field]
[0001] The present invention relates to a plate type heat exchanger including a cut plate,
and more particularly, to a plate type heat exchanger capable of decreasing deformation
stress due to a difference in a temperature of heat exchanged heat media.
[Background Art]
[0002] Heat exchangers are apparatuses for exchanging heat of different fluids and changing
temperatures and phases of the fluids, and have been widely used today in various
technical fields, such as power generation and air conditioning and heating.
[0003] Particularly, a method of a plate type heat exchanger among them may exhibit excellent
heat exchange efficiency, and decrease a volume and weight of the heat exchanger,
so that a related technique has been actively developed.
[0004] The plate type heat exchanger has a structure in which two heat media flowing along
internal flow paths are heat exchanged through internal plates, and both surfaces
of each plate are in contact with the heat media having different temperatures.
[0005] In this case, regions around an inlet and outlet for supplying and discharging the
heat media into and from the plate type heat exchanger have the greatest difference
in a temperature, and this may cause thermal deformation of the plate type heat exchanger
due to the difference in a temperature between the two heat media.
[0006] In a heat exchanger in the related art, a plurality of plates and a supporting means
for fixing an interval between the plates, and supporting and coupling the plates
are firmly coupled, so that thermal deformation stress due to a difference in a temperature
between heat media is directly transmitted to each element of the plate type heat
exchanger, and as a result, there is a problem in that the plate type heat exchanger
is damaged.
[0007] In the meantime, the heat media flowing inside the plate type heat exchanger are
heat exchanged while flowing along flow paths, and in this case, when a vortex is
generated in the flow of the heat media, heat exchange efficiency of the heat media
is increased.
[0008] Accordingly, in order to generate a vortex in the flow of the heat media, the plate
is processed into various forms for use, but there is a problem in that costs and
time for manufacturing the plate type heat exchanger increase. A plate type heat exchanger
showing the features of the preamble of claims 1 and 5 is disclosed by document
US-20060289147A.

<First Exemplary Embodiment>
[0024] First, a configuration of a first exemplary embodiment of a plate type heat exchanger
including a cut plate according to the present invention will be described in detail
with reference to FIGS. 1 to 3.
[0025] Here, FIG. 1 is a schematic diagram illustrating a first exemplary embodiment of
a plate type heat exchanger including cut plates according to the present invention,
FIG. 2 is an exploded perspective diagram illustrating the first exemplary embodiment
of the plate type heat exchanger including cut plates according to the present invention,
and FIG. 3 is a schematic diagram illustrating a modified example of the first exemplary
embodiment of the plate type heat exchanger including cut plates according to the
present invention.
[0026] As illustrated in FIGS. 1 and 2, a first exemplary embodiment of a plate type heat
exchanger including cut plates according to the present invention may include plates
100, a reinforcing part 200, and cut plates 300.
[0027] A plurality of plates 100 is disposed so that first flow paths and second flow paths,
in which different heat media are heat exchanged and flow, respectively, in the plate
type heat exchanger according to the present invention, are repeatedly formed, and
may be formed of a material having a high heat transfer rate.
[0028] More particularly, the plate 100 may divide spaces of the first flow paths and the
second flow paths, which are repeatedly formed in the plate type heat exchanger, and
may be formed so that heat energy of the different heat media flowing in the first
flow path and the second flow path, respectively, is allowed to pass through, so that
the two heat media are heat exchanged with each other.
[0029] Various materials and shapes of the plate 100 may be adopted without limitations
as long as the plurality of the plates 100 is disposed so as to divide the spaces
of the first flow paths and the second flow paths, which are repeatedly formed in
the plate type heat exchanger, and has a high heat transfer rate to allow the two
heat media to be heat exchanged.
[0030] In the meantime, the reinforcing part 200 is a configuration provided between the
plurality of plates 100, and supporting the plates 100 so that the plates 100 are
disposed to be spaced apart from each other, and may be formed so as to allow the
heat media to flow while having a predetermined thickness.
[0031] In the present exemplary embodiment, the reinforcing part 200 may be formed in a
corrugated plate form having corrugation that has a height corresponding to an interval
between the plates 100, which are disposed while being spaced apart from each other.
In this case, the reinforcing part 200 may be disposed so that a direction, in which
the same height is maintained in the corrugation of the reinforcing part 200, is the
same as a flow direction F of the heat media so as to prevent the corrugation shape
formed in the reinforcing part 200 from blocking the flow of the heat media.
[0032] The configuration of the reinforcing part 200 is not limited to the present exemplary
embodiment, and a material and a shape of the reinforcing part 200 may be varied without
limitations as long as the reinforcing part 200 is configured to maintain the interval
between the plates 100, support the plurality of plates 100, and allows the heat media
to flow.
[0033] In the meantime, the cut plate 300 is a configuration provided between the plate
100 and the reinforcing part 200, and may be formed in the form in which the plate
having a size corresponding to the plate 100 is partially cut.
[0034] In the present exemplary embodiment, the cut plate 300 may be formed in the form
in which regions adjacent to an inlet and an outlet, through which the heat media
are supplied to and discharged from the first flow path and the second flow path formed
by the plurality of plates 100 when being coupled with the plate 100 and the reinforcing
part 200, are cut.
[0035] The configuration forms the irregular flow paths formed between the plates 100, and
thus a vortex is generated while the heat media flow in the flow paths formed between
the plates 100, thereby achieving an effect of improving heat exchange efficiency
of the heat media.
[0036] Further, the cut plate 300 may also be formed by a pillar for coupling the plate
100 and the reinforcing part 200.
[0037] For example, when the plate 100 and the reinforcing part 200 are coupled by using
a pillar formed of copper in order to couple the structure of the plate 100 and the
reinforcing part 200 formed of aluminum, the plate 100 and the reinforcing part 200
may be coupled by disposing the pillar formed of copper to be partially cut.
[0038] In this case, the pillar may be formed so that regions adjacent to the inlet and
the outlet of the heat media are cut similar to the aforementioned cut plate 300.
[0039] The configuration of the cut plate 300 is not limited to the present exemplary embodiment,
and a material and a shape of the cut plate 300 may be varied without limitations
as long as the cut plate 300 is provided between and coupled with the plate 100 and
the reinforcing part 200, and has a cut part.
[0040] In the first exemplary embodiment of the plate type heat exchanger including the
cut plate according to the present invention including the aforementioned configuration,
the flow path in the regions adjacent to the heat media inlet and outlet of each flow
path having the greatest difference in a temperature between the two heat media may
be irregularly formed, so that it is possible to achieve an effect in that heat exchange
efficiency of the heat media is further improved.
[0041] Further, it is not necessary to separately process the plate 100 in order to form
a vortex in the flow of the heat media, and only a simple cutting process is performed
on the cut plate 300, so that it is possible to achieve an effect of reducing costs
and time taken for manufacturing the plate type heat exchanger according to the present
invention. Further, the coupling of the structure configuring the plate type heat
exchanger according to the present invention is relatively lightly formed in the region
having the greatest difference in a temperature between the heat media at each flow
path, so that it is possible to allow slight thermal deformation of each configuration.
[0042] Accordingly, it is possible to achieve an effect of preventing the plate type heat
exchanger according to the present invention from being damaged by decreasing thermal
deformation stress applied to each structure.
[0043] In the meantime, a modified example of the first exemplary embodiment of the plate
type heat exchanger including the cut plate according to the present invention will
be described in detail with reference to FIG. 3 below.
[0044] Here, FIG. 3 is a schematic diagram illustrating a modified example of the first
exemplary embodiment of the plate type heat exchanger including cut plates according
to the present invention.
[0045] As illustrated in FIG. 3, a modified example of the first exemplary embodiment of
the plate type heat exchanger including cut plates according to the present invention
may include plates 100, a reinforcing part 200, and cut plates 300, similar to the
aforementioned first exemplary embodiment.
[0046] Here, the plate 100 and the cut plate 300 have the same configurations as those of
the aforementioned first exemplary embodiment, and the configuration of the reinforcing
part 200 is basically the same as that of the aforementioned reinforcing part 200,
so that detailed descriptions thereof will be omitted.
[0047] However, in the present modified example, the reinforcing part 200 may include a
plurality of through holes 210.
[0048] The configuration of the through holes 210 enable heat media to pass through the
reinforcing part 200, and thus it is possible to achieve an effect in that the heat
media more freely flow along flow paths between the plates 100.
[0049] Further, the flow path may be more irregularly formed by each through hole 210 while
the heat media flow along the flow paths between the plates 100.
[0050] Accordingly, a more complex vortex is generated in the flow of the heat media, so
that it is possible to achieve an effect in that heat exchange efficiency of the heat
media is further improved.
<Second Exemplary Embodiment>
[0051] Next, a configuration of a second exemplary embodiment of a plate type heat exchanger
including a cut plate according to the present invention will be described in detail
with reference to FIG. 4.
[0052] Here, FIG. 4 is an exploded perspective diagram illustrating a second exemplary embodiment
of a plate type heat exchanger including a cut plate according to the present invention.
[0053] As illustrated in FIG. 4, a second exemplary embodiment of a plate type heat exchanger
including a cut plate according to the present invention may include plates 400 and
a reinforcing cut plate 500.
[0054] Here, the plate 400 has the same configuration as that of the aforementioned plate
100 of the first exemplary embodiment of the plate type heat exchanger including the
cut plates according to the present invention, so that a detailed description thereof
will be omitted.
[0055] In the meantime, the reinforcing cut plate 500 is a configuration provided between
the plurality of aforementioned plates 400, supporting the plates 400 so that the
plates 400 are disposed so as to be spaced apart from each other, and having a cut
part, and may be formed so as to allow the heat media to flow while having a predetermined
thickness.
[0056] In the present exemplary embodiment, the reinforcing cut plate 500 may be formed
in a corrugated plate form having corrugation that has a height corresponding to an
interval between the plates 400 which are disposed while being spaced apart from each
other.
[0057] In this case, the reinforcing cut plate 500 may be disposed so that a direction,
in which the same height is maintained in the corrugation of the reinforcing cut plate
500, is the same as a flow direction F of the heat media so as to prevent the corrugation
shape formed in the reinforcing cut plate 500 from blocking the flow of the heat media.
[0058] Further, in the present exemplary embodiment, regions of the reinforcing cut plate
500 adjacent to an inlet and an outlet, through which the heat media are supplied
to and discharged from a first flow path and a second flow path formed by the plurality
of plates 400, may be cut.
[0059] The configuration forms the irregular flow paths formed between the plates 400, and
thus a vortex is generated while the heat media flow in the flow paths formed between
the plates 400, thereby achieving an effect of improving heat exchange efficiency
of the heat media.
[0060] That is, the reinforcing cut plate 500 may be formed by a configuration including
a combination of a property of the reinforcing part 200 and a property of the cut
plate 300 of the aforementioned first exemplary embodiment.
[0061] The configuration of the reinforcing cut plate 500 is not limited to the present
exemplary embodiment, and a material and a shape of the reinforcing cut plate 500
may be varied without limitations as long as the reinforcing cut plate 500 maintains
the interval between the plates 400, supports the plurality of plates 400, allows
the heat media to flow, and has a cut part.
[0062] In the second exemplary embodiment of the plate type heat exchanger including the
cut plate according to the present invention including the aforementioned configuration,
the flow path in the regions adjacent to the heat media inlet and outlet of each flow
path having the greatest difference in a temperature between the two heat media may
be irregularly formed, similar to the aforementioned first exemplary embodiment, so
that it is possible to achieve an effect in that heat exchange efficiency of the heat
media is further improved.
[0063] Further, it is not necessary to separately process the plate 100 in order to form
a vortex in the flow of the heat media, and only a simple cutting process is performed
on the reinforcing cut plate 500, so that it is possible to achieve an effect of reducing
costs and time taken for manufacturing the plate type heat exchanger according to
the present invention.
[0064] Further, the coupling of the structure configuring the plate type heat exchanger
according to the present invention is relatively lightly formed in the region having
the greatest difference in a temperature between the heat media at each flow path,
so that it is possible to allow slight thermal deformation of each configuration.
[0065] Accordingly, it is possible to achieve an effect of preventing the plate type heat
exchanger according to the present invention from being damaged by decreasing thermal
deformation stress applied to each structure.
[0066] Further, the relatively less number of configurations are used compared to the aforementioned
first exemplary embodiment, so that it is possible to achieve an effect of reducing
time and costs taken for manufacturing the plate type heat exchanger including the
cut plate according to the present invention.
[0067] In the meantime, a modified example of the second exemplary embodiment of the plate
type heat exchanger including the cut plate according to the present invention will
be described in detail with reference to FIG. 5 below.
[0068] Here, FIG. 5 is a schematic diagram illustrating a modified example of the second
exemplary embodiment of the plate type heat exchanger including the cut plate according
to the present invention.
[0069] As illustrated in FIG. 5, a modified example of the second exemplary embodiment of
the plate type heat exchanger including the cut plate according to the present invention
may include plates 400 and a reinforcing cut plate 500, similar to the aforementioned
second exemplary embodiment.
[0070] Here, the plate 400 has the same configurations as that of the aforementioned second
exemplary embodiment, and the configuration of the reinforcing cut plate 500 is basically
the same as that of the aforementioned reinforcing cut plate 500, so that detailed
descriptions thereof will be omitted.
[0071] However, in the present modified example, the reinforcing cut plate 500 may include
a plurality of through holes 510.
[0072] The configuration of the through hole 510 enables heat media to pass through the
reinforcing cut plate 500, similar to the aforementioned modified example of the first
exemplary embodiment, so that it is possible to achieve an effect in that the heat
media more freely flow along flow paths between the plates 400.
[0073] Further, the flow path may be more irregularly formed by each through hole 510 while
the heat media flow along the flow paths between the plates 400.
[0074] Accordingly, a more complex vortex is generated in the flow of the heat media, so
that it is possible to achieve an effect in that heat exchange efficiency of the heat
media is further improved.
[0075] In the meantime, the specific exemplary embodiment of the present invention is described
and illustrated as described above, but those skilled in the art will appreciate that
the present invention is not limited to the described exemplary embodiment, and may
be variously changed and modified without departing from the spirit and the scope
of the present invention. Accordingly, changed examples or modified examples should
not be individually understood from the technical spirit or the aspect of the present
invention, and the modified exemplary embodiments belong to the claims of the present
invention.
