Description

Technical Field

[0001] The utility model relates to the field of compressors, in particular to a heat dissipation device for a screw compressor. Background Technique

[0002] A compressor is a driven fluid machine that raises low-pressure gas to high-pressure gas. It sucks in low-temperature and low-pressure refrigerant gas from the suction pipe, compresses it by driving a piston through the operation of an electric motor, and discharges high-temperature and high-pressure refrigerant gas to the exhaust pipe, providing power for the refrigeration cycle, thereby realizing the refrigeration cycle of compression, condensation, expansion, and evaporation. After retrieving the public number CN220248364U of the patent office database for a heat dissipation device of a screw compressor, the inside of the conduit is injected with coolant, and the conduit penetrates through the heat dissipation fins. When cooling the screw compressor, the hot air at the top is cooled for the first step under the action of the coolant inside the conduit and the heat dissipation fins. The inlet fan blade drives the air flow into the top of the screw compressor, and then the hot air flows out through the outlet duct under the action of the outlet fan blade, continuously replacing the air at the top of the screw compressor, thereby reducing the heat. However, the heat dissipation device only dissipates heat from the top of the screw compressor, and the heat dissipation effect of the screw compressor needs to be improved;

[0003] Therefore, it is very necessary to invent a heat dissipation device for a screw compressor. Content of the Utility Model

A first support plate 22 is also installed at the upper end of the screw compressor 1. The first support plate 22 is used to support and install the heat dissipation fan group 221. The heat dissipation fan group 221 is installed on the first support plate 22. The heat dissipation fan group 221 is arranged behind the first heat sink group 21 and is used to blow air on the first heat sink group 21 and the liquid guide copper tube 24, accelerate the air flow between the first heat sink groups 21, and accelerate the cooling and heat dissipation of the heat on the first heat sink group 21;

[0028] A heat conduction plate 27 is installed at the bottom of the screw compressor 1. The heat conduction plate 27 is used to conduct heat and dissipate heat from the screw compressor 1. A semiconductor refrigerator 271 is installed at the bottom of the heat conduction plate 27. The model of the semiconductor refrigerator 271 is HS-TEC120. Through its Peltier effect, the semiconductor refrigerator 271 allows direct current to pass through different semiconductor materials and forms an electric couple under the action of series connection. At this time, heat is absorbed and released at both ends of the electric couple, thereby accelerating the heat dissipation of the semiconductor refrigerator 271.

[0029] A second support plate 25 is also installed at the bottom of the screw compressor 1. The second support plate 25 can not only support and install the radiator 251, but also support the screw compressor 1. A radiator 251 is installed inside the second support plate 25. The model of the radiator 251 is SC-300T. The function of the radiator 251 is to dissipate heat and cool. A circulation pump 26 is installed at one end of the radiator 251. The model of the circulation pump 26 is MP. The circulation pump 26 is used to pump out the condensate in the radiator 251 and transport it into the liquid guide copper tube 24, so that the condensate circulates to cool the first fin group 21 and the second fin group 23. The liquid guide copper tube 24 is installed on the inner walls of the first fin group 21 and the second fin group 23. The liquid guide copper tube 24 conducts heat and dissipates heat from the first fin group 21 and the second fin group 23.

The other end of the support rod 282 is connected to the mounting plate 29. The mounting plate 29 is used to support and install the sponge sleeve 291. After pouring water into the groove 292, the mounting plate 29 supports the sponge sleeve 291 to flip and insert between the first fin groups 21, and wipes the first fin groups 21 with water. After the water on the first fin groups 21 evaporates, it will take away the heat on the first fin groups 21 and accelerate the heat dissipation of the first fin groups 21. A sponge sleeve 291 is installed on the outer wall of the mounting plate 29. A groove 292 is opened on the sponge sleeve 291. A first support foot 13 is installed at the front bottom of the screw compressor 1, and a second support foot 14 is installed at the rear bottom of the screw compressor 1. The screw compressor 1 is supported by the first support foot 13 and the second support foot 14 respectively, increasing the use stability of the screw compressor 1.

[0031] The working principle of the present utility model is as follows: The first heat sink group 21 and the second heat sink group 23 are respectively used to conduct heat dissipation for the screw compressor 1. Then, the heat dissipation fan group 221 blows air on the first heat sink group 21 and the liquid guide copper tube 24 to accelerate the air flow between the first heat sink group 21, and accelerate the cooling and heat dissipation of the heat on the first heat sink group 21. The circulation pump 26 pumps out the condensate in the radiator 251 and transports it into the liquid guide copper tube 24, so that the condensate circulates to cool the first heat sink group 21 and the second heat sink group 23. The heat conducting plate 27 conducts heat dissipation for the bottom of the screw compressor 1, and the semiconductor refrigerator 271 absorbs heat from the heat conducting plate 27 for heat dissipation, thereby accelerating the heat dissipation of the semiconductor refrigerator 271. Finally, after pouring water into the groove 292 of the sponge sleeve 291, the motor 283 drives the rotating rod 281 to rotate, the rotating rod 281 drives the support rod 282 and the sponge sleeve 291 to flip, the sponge sleeve 291 flips and inserts between the first heat sink group 21, and wipes the first heat sink group 21 with water. After the water on the first heat sink group 21 evaporates, it will take away the heat on the first heat sink group 21 and accelerate the heat dissipation of the first heat sink group 21.
