CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims priority to Chinese Patent Application No.
201710080370.4, entitled "Heat dissipation assembly and refrigeration device" filed on February
15, 2017, which is hereby incorporated by reference in its entirety.
TECHNICAL FIELD
[0002] The present disclosure relates to the field of refrigeration technology, more particularly
to a heat dissipation assembly and a refrigeration device.
BACKGROUND
[0003] Nowadays, the size of refrigerators is getting bigger and bigger, the requirement
of energy consumption is getting higher and higher. In the compressor compartment
with limited space, there are heat generating equipment such as the compressor and
the condenser, the compressor compartment is ventilated and dissipated by the fan.
In such a compact space, the key factor for improving the overall performance of the
refrigerator is enhancing the heat dissipation effect, which is achieved by reducing
flow resistance by means of a reasonable flow path design.
[0004] At present, the main equipment inside the compressor compartment mainly comprises
a compressor, a condenser, a condenser fan, generally, the condenser is a tube-and-fin
type. As the energy source of the whole refrigeration system, the compressor compresses
a low-temperature and low-pressure refrigerant into a high-temperature and high-pressure
superheated air by the movement of a rotational mechanical action, a large amount
of heat is generated in this process. The high-temperature and high-pressure refrigerant
superheated air is discharged from an outlet of the compressor, entered into the condenser
and subjected to forced air convection heat exchange with the surrounding air by means
of a condensing fan. In such a narrow space, the heat exchanging efficiency of the
compressor and the condenser directly affect the refrigeration performance of the
entire refrigerator system. At the same time, both the compressor and the condensing
fan are rotating machines that generate noise during operation, wherein the compressor
mainly generates vibration noise and the condensing fan mainly generates pneumatic
noise. The noise level of the compressor and condensing fan will directly affect the
noise performance of the whole machine.
[0005] Due to the limited space, the existing refrigerator products have problems of insufficient
heat dissipation capacity and high noise level:
There is a problem with the heat dissipation of the compressor. Due to the influence
of the spatial layout and the air-flow field, on a leeward side of the compressor,
the amount of heat carried by the air is reduced due to a reduced flow rate, thus
the heat cannot be effectively dissipated.
[0006] There is a problem in the heat dissipation of the condenser. Due to the limited space
and the structure of the condenser itself, when the air flows through the condenser,
the air resistance is large, the flow rate is lowered, the heat dissipation performance
is reduced.
[0007] The compressor generates vibration noise when compressing the refrigerant from a
low-temperature and a low-pressure state to a high-temperature and a high-pressure
state by means of a rotating structure, which is the main source of refrigerator noise
and seriously affects the noise performance of the refrigerator.
[0008] The flow is lost due to a portion of the air flowing through the space below the
condenser.

[0009] In order to solve at least one of the above technical problems, the embodiment of
a first aspect of the present disclosure provides a heat dissipation assembly.

202, the compressor 206 are arranged inside the compressor compartment assembly 30.
[0079] In the embodiment, the heat dissipation assembly 1, the fan 204, the condenser 202,
the compressor 206 are arranged inside the compressor compartment assembly 30. Typically,
the compressor compartment assembly 30 is arranged at the bottom of the refrigerator
8, such a centralized arrangement facilitates the installation, management and maintenance
of the refrigerator. In addition, excess condensed water or accumulated water in the
condenser 202 or the water pan 110 can be discharged by means of the water outlet
arranged on the compressor compartment base.
[0080] In one embodiment of the disclosure, preferably, the compressor 206 comprises a rotational
speed detecting device for detecting a rotational speed of the compressor 206; the
fan 204 comprises a rotational speed control device, which is connected to the rotational
speed detecting device and is configured to control the rotational speed of the fan
204 according to the rotational speed of the compressor 206.
[0081] In the embodiment, the rotational speed of the fan 204 can be adjusted according
to the rotational speed of the compressor 206. For example, when the speed of the
compressor 206 rises, it indicates that the refrigerator 8 is operating at a high
load, it is necessary to dissipate heat more efficiently for the compressor 206 and
the condenser 202. At this time, the speed of the fan 204 can be increased to improve
the heat dissipation capability; when the speed of the compressor 206 is reduced or
the compressor 206 is stopped, the fan 204 speed can be appropriately reduced at this
time to save energy.
[0082] In one embodiment of the present disclosure, preferably, the refrigeration device
is selected from the group consisting of: a refrigerator, a freezer, an air conditioner.
[0083] In the embodiment, the refrigerator, the freezer or the air conditioner can reduce
the flow rate and the flow velocity loss of the airflow by using the above-mentioned
heat dissipation assembly 1, so as to improve heat exchange efficiency of the condenser
202 and refrigeration efficiency of the refrigeration device, save energy. At the
same time, the speed and power consumption of the compressor 206 can also be reduced
due to the increase of the heat exchange efficiency of the condenser 202, thereby
reducing the noise generated by the compressor 206.
[0084] In one embodiment of the present disclosure, preferably, as shown in Fig. 8, the
refrigeration system of the refrigerator comprises the compressor and the condenser
(arranged inside the compressor compartment assembly 30), an evaporator, a centrifugal
fan assembly 40 (arranged between a rear cover assembly 50 and a front cover assembly
60), a refrigerated air duct assembly 70, a refrigerator liner (comprising the refrigeration
compartment), wherein refrigerant and air are circulated in various parts of the refrigeration
system to cool the food in the refrigerator. With the heat dissipating assembly provided
in the present disclosure, ineffective air volume when the air passes through the
condenser 202 can be effectively reduced, the working efficiency of the condenser
202 and the fan 204 is improved, the cooling efficiency and the cooling performance
of the refrigerator 8 are also improved.
[0085] In one embodiment of the present disclosure, preferably, as shown in Fig. 9, the
refrigerator 8 further comprises a control display screen 82. A working state of the
refrigerator 8 can be set by controlling the display screen 82. For example, the cooling
temperature of the freezer compartment and the refrigerating compartment in the refrigerator
8 can be set. It is also possible to temporarily stop cooling for a certain refrigeration
compartment and the like. By setting the control display screen 82 for controlling
the refrigerator 8, the intelligence degree of the refrigerator 8 is improved, so
that the refrigerator 8 can more satisfy the user's needs.
[0086] According to the heat dissipating assembly and the refrigerating device provided
in the present disclosure, ineffective ventilation that does not cool the condenser
is reduced, so that the heat exchange efficiency of the condenser and the efficiency
of the fan are increased, the supercooling degree of the refrigerant at the outlet
of the condenser is increased, the refrigeration effect is improved. At the same time,
the rotational speed and power consumption of the compressor can also be reduced due
to the increase of the heat exchange efficiency of the condenser, thereby reducing
the noise generated by the compressor and saving energy.
