Description

Technical Field

[0001] The utility model relates to the technical field of compressor cooling, in particular to a compressor cooling structure. Background Art

[0002] The compressor is a driven fluid machine that boosts low-pressure gas to high-pressure gas. It is the heart of the refrigeration system. It sucks low-temperature, low-pressure refrigerant gas from the suction pipe, compresses it by driving the piston through the motor, and then discharges high-temperature, high-pressure refrigerant gas to the exhaust pipe. During the operation of the compressor, heat is continuously generated. When the heat is too high, it will affect the operation of the internal parts of the compressor and even damage the parts, thereby shortening the service life of the compressor.

[0003] The patent with the authorization announcement number CN213627924U discloses a compressor cooling device, including an outer frame, a heat dissipation port is provided on the upper surface of the outer frame, a heat dissipation fan is installed in the heat dissipation port, two clamps are fixedly installed in the outer frame, a heat conduction plate is provided on the clamp, a water tank is provided in the heat conduction plate, and a water tank for providing circulating water for the water tank is provided outside the outer frame. When in use, starting the heat dissipation fan can speed up the air flow rate in the outer frame, thereby taking away part of the heat generated by the compressor. The compressor is installed between the two clamps, so that the heat conduction plate on the clamp can transfer part of the heat on the compressor housing, and circulating water flows in the water tank, which can also absorb part of the heat transferred from the heat conduction plate.

[0004] The above patent discloses a compressor cooling device that can absorb part of the heat generated by the compressor during operation, thus achieving a cooling effect. However, the heat conducting plates are only located on both sides of the compressor, and the heat conducting area is small, so that the circulating water in the water tank absorbs heat unevenly at the compressor housing, resulting in insufficient cooling effect.

DETAILED DESCRIPTION

[0019] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] The present application embodiment discloses a compressor cooling structure, referring to Figure 1 and Figure 2 , including a box body 2, a mounting frame 3 is bolted to the bottom wall of the box body 2, and a compressor body 1 is bolted to the mounting frame 3. A water storage tank 5 for storing circulating water is welded on the top of the box body 2, and a plurality of turns of a refrigeration pipe 4 for conveying circulating water are spirally wound on the top wall of the box body 2 from top to bottom along the circumference of the compressor body 1. A first opening is opened on the top of the water storage tank 5, and a water outlet hole with a size adapted to the refrigeration pipe 4 is opened on the bottom. The water inlet of the refrigeration pipe 4 is vertically inserted into the water outlet hole of the bottom wall of the water storage tank 5. In order to improve the sealing between the refrigeration pipe 4 and the water outlet hole of the water storage tank 5, a sealing ring can be embedded on the inner side wall of the water outlet hole. The water outlet of the refrigeration pipe 4 passes through the bottom of the box body 2 downward and is connected to a heat dissipation device 6. The end of the heat dissipation device 6 away from the refrigeration pipe 4 is connected to a water pump 7 through a water pipe. The end of the water pump 7 away from the heat dissipation device 6 is inserted with a return pipe 8, and the return pipe 8 extends into the first opening of the water storage tank 5. A first mounting hole is provided on one side of the housing 2, a first cooling fan 9 is installed in the first mounting hole, and a vent is provided on the housing 2 on the opposite side of the first cooling fan 9. A clamping assembly 10 for clamping the upper half of the compressor body 1 is also installed on the side wall of the housing 2 to improve the stability of the compressor body 1 on the mounting frame 3.

[0021] In the embodiment of the present application, the circulating water in the water storage tank 5 flows down along the refrigeration pipe 4 under the action of gravity and absorbs the heat on the compressor body 1. The circulating water that absorbs the heat flows to the heat dissipation device 6 along the water outlet of the refrigeration pipe 4. The circulating water that dissipates the heat through the heat dissipation device 6 is then pumped into the return pipe 8 by the water pump 7, and discharged into the water storage tank 5 along the return pipe 8, so as to achieve the purpose of circulating refrigeration. The refrigeration pipe 4 is spirally wound with multiple turns along the circumference of the compressor body 1, so that the circulating water in the refrigeration pipe 4 can be more uniform to the heat absorption part of the compressor body 1. The first cooling fan 9 can accelerate the flow rate of the air in the box 2 and improve the cooling effect on the compressor body 1. In order to improve the heat dissipation effect of the refrigeration pipe 4 in the box 2, a plurality of second heat sinks 42 are bolted to the refrigeration pipe 4 to increase the heat dissipation area of ​​the refrigeration pipe 4.

[0022] Specifically, the heat dissipation device 6 includes a heat dissipation groove 61, a second opening is provided at the top of the heat dissipation groove 61, a water outlet of the refrigeration pipe 4 extends to the second opening of the heat dissipation groove 61, a water outlet pipe is plugged into the bottom of the heat dissipation groove 61, and the water outlet pipe is connected to the water pump 7. A plurality of second heat dissipation fans 62 are also installed at the second opening of the heat dissipation groove 61. The circulating water in the refrigeration pipe 4 can flow into the heat dissipation groove 61 along the water outlet, and the second heat dissipation fan 62 can speed up the air flow rate on the liquid surface in the heat dissipation groove 61 to improve the heat dissipation efficiency of the circulating water in the heat dissipation groove 61.

[0023] Reference Figure 3 The outlet of the cooling pipe 4 is connected to a plurality of nozzles 41, and the nozzles of the nozzles 41 face the inner bottom wall of the heat dissipation box. The circulating water discharged from the cooling pipe 4 can be divided into multiple streams by the plurality of nozzles 41, thereby increasing the contact area between the circulating water and the air, thereby improving the heat dissipation efficiency.

[0024] In order to improve the heat dissipation efficiency of the heat dissipation slot 61 for the circulating water, a plurality of second mounting holes are provided on the side wall of the heat dissipation slot 61, and the first heat dissipation fin 63 is inserted into the second mounting holes, and the first heat dissipation fin 63 is connected to the heat dissipation slot 61 by bolts. One end of the first heat dissipation fin 63 extends out of the heat dissipation slot 61, and the other end extends into the heat dissipation slot 61. The circulating water sprayed by the nozzle 41 contacts the first heat dissipation fin 63, which can increase the heat dissipation area of ​​the circulating water and further improve the heat dissipation efficiency.

[0025] The clamping assembly 10 includes at least two cylinders 101, the cylinder bodies of the two cylinders 101 are horizontally bolted to the two side walls of the box body 2, and the piston rods of the cylinders 101 face the upper half of the compressor body 1. A pad 102 whose size matches the outer wall of the upper half of the compressor body 1 is provided on the side of the piston rod close to the compressor body 1. The pad 102 is driven by the two cylinders 101 to abut against and clamp the upper half of the compressor body 1, which can further improve the stability of the compressor body 1.

[0026] In order to prevent the gasket 102 from causing wear to the outer wall of the compressor body 1, a flexible layer (not shown in the figure) is embedded in the side of the gasket 102 that contacts the compressor body 1. The flexible layer can be made of flexible materials such as rubber.

[0027] The implementation principle of the cooling structure of a compressor in the embodiment of the present application is as follows: during the use of the cooling structure of a compressor, the refrigeration pipe 4 is spirally wound along the circumference of the compressor body 1 for multiple turns, and the circulating water in the water storage tank 5 flows down along the spiral of the refrigeration pipe 4 under the action of gravity and absorbs the heat on the compressor body 1. The circulating water that absorbs the heat flows to the heat dissipation device 6 along the outlet of the refrigeration pipe 4, and the circulating water that dissipates the heat through the heat dissipation device 6 is then pumped into the water storage tank 5 by the water pump 7, so as to achieve the purpose of circulating refrigeration. The first cooling fan 9 can speed up the flow rate of the air in the box 2 and improve the cooling effect on the compressor body 1. Compared with the traditional compressor cooling equipment, in the embodiment of the present application, the circulating water is more uniform to the heat absorption part of the compressor body 1, which has the benefit of improving the cooling effect.
