[0002] The compressor is an important component that the refrigerator can refrigerate, and the suction pipe inhales the low-temperature low-pressure refrigerant gas, and after the piston is driven by the motor operation, the high-temperature high-pressure refrigerant gas is discharged to the exhaust pipe, and the high-temperature high-pressure refrigerant gas is compressed again after cooling to be used cyclically.
[0003] The high-temperature high-pressure coolant gas needs to be cooled and cooled down through the heat dissipation device during the cooling process, and the limited heat dissipation structure mostly increases the length of the exhaust pipe and makes the exhaust pipe contact the fin-shaped heat dissipation fin, so that the heat dissipation fin dissipates heat to the surrounding environment through the heat dissipation fin, and a fan is also used to accelerate the air flow rate near the heat dissipation fin to obtain better heat dissipation effect.
[0004] However, after the fin-shaped heat dissipation fin contacts the air, the air cannot quickly and directly leave the surface of the heat dissipation fin, and under the action of the fan, the air gradually leaves the heat dissipation fin in the state of contacting the heat dissipation fin, so that the part of the heat dissipation fin directly opposite the fan has a temperature lower than that of the fan at the edge position, so that the heat dissipation fin cannot better perform the heat dissipation work.

[0009] Further, the heat-dissipating fins are uniformly distributed on the side of the two heat-conducting plates close to the fan assembly and connected to the two heat-conducting plates, and uniform gaps are arranged between the heat-dissipating fins.
[0010] Further, the side of the heat-dissipating fin close to the fan assembly is provided with a circular cavity larger than the rotating radius of the fan assembly, so that the fan of the fan assembly does not contact the heat-dissipating fin during rotation.

[0012] Further, the heat-dissipating pipe is a semicircular hollow ring, and a plurality of heat-dissipating pipes are arranged in a rectangular array on the surface of the heat-conducting plate.
[0013] Further, the output directions of the two fans in the fan assembly are opposite and both face the side of the perforation.

[0023] The side of the heat-conducting plate 2 provided with the heat dissipation fin 3 is provided with a fan assembly 5 connecting the heat-conducting plates 2 on both sides, the heat dissipation fins 3 are uniformly distributed on the side of the two heat-conducting plates 2 close to the fan assembly 5 and connected to the two heat-conducting plates 2, and uniform gaps are arranged between the heat dissipation fins 3, the side of the heat dissipation fin 3 close to the fan assembly 5 is provided with a circular cavity larger than the rotating radius of the fan assembly 5, so as to ensure that the fan of the fan assembly 5 does not contact the heat dissipation fin 3 in the rotating process, two fans are arranged in the fan assembly 5, a plurality of perforations 6 are arranged on the surface of the heat-conducting plate 2 close to the fan assembly 5, the output directions of the two fans in the fan assembly 5 are opposite, and both are directed to the side of the perforation 6, the perforation 6 is in communication with the position of the circular cavity of the heat dissipation fin 3, and each perforation 6 is aligned with the heat dissipation pipe 4, the air leaving through the perforation 6 will contact the heat dissipation pipe 4 and be blocked by the heat dissipation pipe 4 to flow randomly, and the heat in the heat dissipation pipe 4 is taken away in the process of turbulent flow, so as to optimize the heat dissipation effect.
[0024] Working principle: firstly, the compressor sends high-temperature and high-pressure coolant gas into the copper pipe 1 through the connecting pipe and the shunt handle, the coolant gas in the copper pipe 1 transmits the temperature to the copper pipe 1 and then to the heat-conducting plate 2, and then the heat-conducting plate 2 sends the temperature to the heat dissipation fin 3 and the heat dissipation pipe 4, and in this process, the temperature of the coolant gas gradually decreases.
