Description

Technical Field

[0001] The utility model relates to the technical field of compressor heat dissipation, in particular to a refrigerator compressor heat dissipation device. Background Art

[0002] A compressor is a driven fluid machine that can boost low-pressure gas to high-pressure gas. It is widely used in household appliances such as refrigerators. The compressor of a refrigerator is one of the core components of the refrigerator and is the heart of the refrigeration system. It inhales low-temperature and low-pressure refrigerant gas from the suction pipe, compresses it by driving the piston through the motor, and discharges high-temperature and high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle. A compressor is a fluid machine that converts low-pressure condensing agent into high-pressure condensing agent. In the process of compressing the condensing agent, a large amount of heat is released.

[0003] The small and enclosed space at the bottom of the back of the refrigerator is generally reserved for the compressor, and the heat dissipation effect is average, which brings great uncertainty to the use of the compressor. Generally, a heat dissipation device is installed, and the most common heat dissipation device is air cooling, which uses a fan to generate wind to circulate air to dissipate heat from the compressor. However, when the ambient temperature is high, the heat carried away by the air circulation is reduced, resulting in a decrease in the heat dissipation efficiency of the compressor. Therefore, those skilled in the art provide a refrigerator compressor heat dissipation device to solve the problems raised in the above background technology. Utility Model Content

[0004] The purpose of the utility model is to provide a refrigerator compressor heat dissipation device to solve the problems raised in the above background technology.

[0010] As a further solution of the present invention: the liquid storage tank is located between the fan and the compressor body.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] By providing a thin sheet-like transverse plate, the transverse plate can be regarded as a fin-like structural component. When heat is generated during the operation of the compressor body, it can be transferred to the surface of the transverse plate through the outer shell of the compressor body. After the fan is turned on, part of the heat can be taken away from the surface of the compressor body. A liquid storage tank is provided to store coolant, and the coolant is circulated inside the plate and the liquid storage tank through a pump.

When the compressor body 12 generates heat during operation, it can be transferred to the surface of the transverse plate 8 through the outer shell of the compressor body 12, and after the fan 5 is turned on, part of the heat can be taken away from the surface of the compressor body 12.

[0018] Preferably, adjacent transverse plates 8 are connected with longitudinal plates 9, and the longitudinal plates 9 are located at the ends of the transverse plates 8, and the ends of each transverse plate 8 are connected to at most one longitudinal plate 9, and the interiors of the transverse plates 8 and the longitudinal plates 9 are both hollow, and the interiors of the transverse plates 8 and the longitudinal plates 9 are interconnected.

[0019] Preferably, a liquid storage box 6 is detachably installed inside the installation chamber 2, and the bottom end of the liquid storage box 6 is connected to a liquid outlet nozzle 7, and the other end of the liquid outlet nozzle 7 is connected to the lowermost horizontal plate 8. A pump 11 is installed on the top of the installation chamber 2, and the output end of the pump 11 is connected to the inside of the liquid storage box 6, and the input end of the pump 11 is connected to a recovery pipe 10, and the other end of the recovery pipe 10 is connected to the uppermost horizontal plate 8.

[0020] Preferably, the liquid storage box 6 is arranged in a grid plate shape, and the interior of each plate-shaped frame of the liquid storage box 6 is interconnected, and the interior of the liquid storage box 6 is filled with cooling liquid.

[0022] The working principle of the utility model is as follows: when the refrigerator is used, when the compressor body 12 generates a small amount of heat, the fan 5 can be turned on to dissipate the heat. Since the surface of the compressor body 12 is provided with a transverse plate 8, the transverse plate 8 can be regarded as a fin-shaped component. When the compressor body 12 generates heat during operation, the heat can be transferred to the surface of the transverse plate 8 through the outer shell of the compressor body 12. After the fan 5 is turned on, part of the heat can be taken away from the surface of the compressor body 12. When the compressor body 12 generates a large amount of heat, the pump 11 can be turned on to cool the coolant in the liquid storage tank 6. The coolant can flow from the liquid outlet 7 into the interior of the transverse plate 8. After passing through the longitudinal plate 9 and the transverse plate 8 for multiple times, the coolant flows back into the interior of the liquid storage tank 6. The transverse plate 8 is cooled by the coolant, thereby carrying away excess heat. The liquid storage tank 6 adopts a grid plate structure, which can expand the contact area between the coolant and the liquid storage tank 6. The coolant after absorbing heat can fully contact the inner wall surface of the liquid storage tank 6. The liquid storage tank 6 is located on one side of the fan 5. After the fan 5 is turned on, the heat on the surface of the liquid storage tank 6 can be taken away, thereby enhancing the heat dissipation effect of the compressor body 12.
