Description

Technical Field

[0001] This utility model relates to the technical field of air compressor heat dissipation devices, specifically to a high-efficiency heat dissipation device for a high-pressure oxygen chamber air compressor. Background Technology

[0002] With the widespread application of hyperbaric oxygen chambers in medical rehabilitation, high-altitude / air ambulance services, emergency treatment of acute poisoning, and treatment of decompression sickness, the hyperbaric oxygen chamber air compressor is the core component for maintaining pressure and airflow circulation within the chamber. During long-term continuous operation, it generates a significant amount of heat. If heat dissipation is insufficient, it can lead to excessive temperature rise in the motor and compressor, causing decreased efficiency and mechanical wear. Furthermore, it may affect temperature and humidity control within the chamber, reducing patient safety and comfort.

[0003] Currently, traditional heat dissipation methods mainly include air cooling and liquid cooling. Air cooling requires additional fans and air ducts, which occupy cabin space and generate significant noise and vibration. Liquid cooling requires the installation of liquid pumps and pipelines, resulting in a complex structure and insufficient operational stability, making it difficult to simultaneously meet the requirements of hyperbaric oxygen chambers for compactness, low noise, and high reliability.

[0004] Based on this, this utility model designs a high-efficiency heat dissipation device for a high-pressure oxygen chamber air compressor to solve the problems of large space occupation, noise and reliability of the aforementioned heat dissipation devices. Utility Model Content

[0017] Through the above-mentioned structural design of evaporator 1, evaporator 1 can be designed as a flat plate, arc or irregular shape, so that its outer surface can be closely attached to the heating surface of the hyperbaric oxygen chamber air compressor, which facilitates the rapid transfer of heat from the hyperbaric oxygen chamber air compressor, thereby controlling the working temperature of the hyperbaric oxygen chamber air compressor within a reasonable range.

[0018] The vertical parallel flow falling film condenser 3 includes an upper tube body 301, a lower tube body 302, a parallel channel 303, a second inlet end 304, a second outlet end 305, and fins 306. Multiple parallel channels 303 are provided between the upper tube body 301 and the lower tube body 302, and the parallel channels 303 connect the upper tube body 301 and the lower tube body 302. One end of the upper tube body 301 is provided with a second inlet end 304 and the other end is closed. One end of the lower tube body 302 is provided with a second outlet end 305 and the other end is closed. Multiple fins 306 are evenly distributed on the parallel channel 303 between the upper tube body 301 and the lower tube body 302.

[0019] The parallel flow falling film condenser 3 described above uses a parallel loop design to ensure that the flow path length and flow direction of the refrigerant or cooling medium in each parallel channel are basically consistent. With this structure, the flow resistance of each loop is similar, thereby ensuring the balanced distribution of fluid among multiple channels and avoiding insufficient flow or flow deviation in some channels.

[0020] External threads are provided on the outer walls of the first inlet end 102 and the first outlet end 103, and external threads are also provided on the outer walls of the second inlet end 304 and the second outlet end 305.

[0021] Both ends of the flexible condensate pipe 2 are equipped with sealing quick connectors 5, and both ends of the flexible steam pipe 4 are also equipped with sealing quick connectors 5.

[0022] The two ends of the flexible condenser pipe 2 are connected to the first inlet end 102 on the evaporator 1 and the second outlet end 305 on the vertical parallel flow falling film condenser 3 respectively through the sealing quick connector 5. The two ends of the flexible steam pipe 4 are connected to the first outlet end 103 on the evaporator 1 and the second inlet end 304 on the vertical parallel flow falling film condenser 3 respectively through the sealing quick connector 5.

[0023] The sealing quick connector 5 includes an annular body 501, an insertion end 502, a sealing gasket 503, a sealing ring 504, and a threaded sleeve 505. The insertion end 502 is located at the center of the annular body 501. The insertion end 502 has two annular grooves, and the sealing rings 504 are embedded in each annular groove.

[0024] The structure design of the sealing quick connector 5 facilitates the quick connection and disassembly of the pipeline with the evaporator 1 and the vertical parallel flow falling film condenser 3, while multiple seals ensure the sealing effect at the connection.

[0025] The working principle and usage process of this utility model are as follows: In specific use, firstly, a vacuum operation is performed on the flexible condenser pipe 2 and the flexible steam pipe 4. Then, a certain amount of suitable circulating working fluid is charged. The amount of circulating working fluid to be charged needs to be determined in advance through test to achieve the optimal charging amount. Then, the evaporator 1 is placed on the heat dissipation surface of the high-pressure oxygen chamber air compressor. Thermal grease is applied or thermal pads are placed between the high-pressure oxygen chamber air compressor and the evaporator 1 to reduce contact thermal resistance. The heat from the high-pressure oxygen chamber air compressor is transferred to the evaporator 1 through heat conduction. The circulating working fluid in the evaporator 1 undergoes a phase change after being heated. After absorbing heat and undergoing a phase change, the gaseous circulating working fluid enters the vertical parallel flow falling film condenser 3 through the flexible steam pipe 4. It releases heat to the external environment through indirect heat exchange on the inner wall of the flow channel, thereby condensing into a liquid circulating working fluid. The liquid circulating working fluid enters the liquid storage chamber 105 of the evaporator 1 through the flexible condensation pipe 2. Under the action of capillary force of the liquid suction core 104 in the evaporator 1, the liquid working fluid in the liquid storage chamber 105 absorbs heat and changes into a gaseous state. It then enters the vertical parallel flow falling film condenser 3 through the flexible steam pipe 4, thus forming a working fluid circulation and heat transfer process, achieving efficient heat dissipation of the high-pressure oxygen chamber air compressor.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
