Description

An oil cooler structure for a cryogenic compressor Technical Field

[0001] This utility model relates to the technical field of oil cooler structure, specifically to an oil cooler structure for a cryogenic compressor. Background Technology

[0002] Cryogenic compressors are specialized compressors designed for compressing cryogenic gases (such as liquid nitrogen, liquid helium, and natural gas). They are widely used in liquefied natural gas (LNG), air separation equipment, cryogenic experimental devices, and superconducting technology. During operation, these compressors require cooling structures. However, current cooling methods primarily rely on oil cooling. During oil cooling, impurities easily accumulate in the pipes and oil tank. These impurities, flowing through narrow pipes, can cause blockages, affecting the normal operation of the oil cooler. Furthermore, in hot weather, oil cooling alone can lead to insufficient cooling efficiency and poor cooling performance. Therefore, improvements to existing technologies are necessary. Summary of the Invention

[0003] The purpose of this invention is to provide an oil cooler structure for a cryogenic compressor, which solves the problems of impurities inside the cooling oil easily clogging the pipes and insufficient cooling efficiency when the weather is hot.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an oil cooler structure for a cryogenic compressor, comprising a base, a compressor fixedly mounted on the upper end of the base, a connecting pipe mounted on the left end of the compressor, an auxiliary cooling mechanism on the base, multiple evenly distributed heat sinks fixedly connected to the outer side of the compressor, a heat dissipation pipe fixedly connected inside the multiple heat sinks, a liquid supply pipe fixedly connected to one end of the heat dissipation pipe, a return pipe fixedly connected to the other end of the heat dissipation pipe away from the liquid supply pipe, a pump body fixedly mounted on the back of the base, a suction pipe fixedly connected to the outer side of the input end of the pump body, an oil tank fixedly mounted on the back of the base, a filter pipe fixedly connected to the inner side of the suction pipe located inside the oil tank, a filter cover fixedly connected to the outer side of the filter pipe, the filter cover contacting the oil tank, and the filter cover contacting the suction pipe.

[0005] Preferably, the heat sink is fixedly connected to the base, and the suction pipe is fixedly connected to the oil tank. The suction pipe can draw the lubricating oil inside the oil tank into the pump body.

[0006] Preferably, the return pipe is fixedly connected to the oil tank, and the supply pipe is fixedly connected to the output end of the pump body. The return pipe can return the cooled oil after heat exchange to the inside of the oil tank.

[0007] Preferably, the filter cover is filled with filter media, which is in contact with the filter tube and can filter impurities.

[0008] Preferably, a refueling pipe is fixedly installed at the upper end of the fuel tank, and a sealing cap is threadedly connected to the outside of the refueling pipe to seal the refueling pipe.

[0009] Preferably, the auxiliary cooling mechanism includes side plates, and two symmetrically distributed side plates are fixedly connected to the upper end of the base. A fan is fixedly connected to the upper end of the two side plates. An air inlet is provided inside the side plate, and the fan can increase the airflow speed on the surface of the heat sink.

[0010] Preferably, there are multiple air inlets, which are evenly distributed on the side plate. The air inlets are conical in shape, which can increase the flow rate of air when it flows.

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

[0012] 1. This utility model adds a filter cover, filter tube and filter material to the suction pipe. When the pump body generates suction force, the suction force absorbs the cooling oil through the suction pipe. The oil can only enter the interior of the suction pipe after being filtered by the filter cover, filter material and filter tube, thus effectively preventing impurities from clogging the heat dissipation pipe.

[0013] 2. This utility model adds a side plate, a fan and an air inlet to the base. During use, the fan can guide the airflow. After the airflow is guided, it is accelerated by the inclined surface of the air inlet and then blown onto the heat sink. This increases the heat dissipation efficiency by increasing the air flow speed on the surface of the heat sink. Attached Figure Description

[0022] Please refer to Figures 1-6. An oil cooler structure for a cryogenic compressor includes a base 1. A compressor 2 is fixedly mounted on the upper end of the base 1. A connecting pipe 3 is mounted on the left end of the compressor 2. An auxiliary cooling mechanism 4 is provided on the base 1. Multiple evenly distributed heat sinks 5 are fixedly connected to the outside of the compressor 2. A heat dissipation pipe 6 is fixedly connected inside the multiple heat sinks 5. A liquid supply pipe 7 is fixedly connected to one end of the heat dissipation pipe 6. A return pipe 8 is fixedly connected to the other end of the heat dissipation pipe 6 away from the liquid supply pipe 7. A pump body 9 is fixedly mounted on the back of the base 1. A suction pipe 11 is fixedly connected to the outside of the input end of the pump body 9. An oil tank 10 is fixedly mounted on the back of the base 1. A filter pipe 14 is fixedly connected to the inside of one end of the suction pipe 11 located inside the oil tank 10. A filter cover 13 is fixedly connected to the outside of the filter pipe 14. The filter cover 13 is in contact with the oil tank 10 and the suction pipe 11.

[0023] Please refer to Figures 1-6. The heat sink 5 is fixedly connected to the base 1, the suction pipe 11 is fixedly connected to the oil tank 10, and the suction pipe 11 can draw the lubricating oil inside the oil tank 10 into the pump body 9. The return pipe 8 is fixedly connected to the oil tank 10, and the supply pipe 7 is fixedly connected to the output end of the pump body 9. The return pipe 8 can return the cooling oil after heat exchange to the inside of the oil tank 10. The filter cover 13 is filled with filter media 15, which is in contact with the filter pipe 14. The filter media 15 can filter impurities. The oil filling pipe 16 is fixedly installed at the upper end of the oil tank 10. The outside of the oil filling pipe 16 is connected to a sealing cap 12 by threads. The sealing cap 12 can seal the oil filling pipe 16.

[0024] Please refer to Figures 1-6. The auxiliary cooling mechanism 4 includes a side plate 41. Two symmetrically distributed side plates 41 are fixedly connected to the upper end of the base 1. A fan 42 is fixedly connected to the upper end of the two side plates 41. An air inlet 43 is opened inside the side plate 41. The fan 42 can increase the air flow speed on the surface of the heat sink 5. There are multiple air inlets 43, which are evenly distributed on the side plate 41. The shape of the air inlet 43 is conical. The conical shape can increase the flow speed when the air flows.

[0025] The specific implementation process of this utility model is as follows: When in use, the compressor 2 generates heat, which is transferred to the interior of the heat sink 5. Then, the pump body 9 is started. The pump body 9 absorbs the cooling oil through the suction pipe 11. During the absorption process, the cooling oil can be filtered by the filter cover 13, filter material 15 and filter pipe 14 and then enters the interior of the suction pipe 11. Then, the pump body 9 injects the cooling oil into the interior of the heat sink 6 through the supply pipe 7. During the flow of the cooling oil inside the heat sink 6, it can dissipate heat on the heat sink 5. After heat exchange, the cooling oil can flow back into the interior of the oil tank 10 through the return pipe 8, thereby cooling the heat sink 5 without clogging the heat sink 6.

[0026] When enhanced cooling efficiency is required, the fan 42 is started. After the fan 42 generates suction, the airflow is drawn by the suction and blown towards the heat sink 5 through the air inlet 43 of the side plate 41. When the airflow passes through the air inlet 43, it can be accelerated by the conical surface of the air inlet 43. The accelerated airflow can effectively improve the air cooling efficiency.
