[0054] Figures 1 to 6 A quick-release compressor heat dissipation shell assembly provided by the present application is applied to an equipment, which can be an oxygen generator or other equipment requiring a compressor, such as a refrigerator, a freezer, etc.

[0055] The quick-release compressor heat dissipation shell assembly comprises an inner shell assembly 200 and a third shell 23. The inner shell assembly 200 forms an inner cavity for mounting a compressor assembly 24 inside. The top of the inner shell assembly 200 is provided with an air inlet 2101 for communicating with the equipment. The inner shell assembly 200 is also provided with an air outlet 2201. The opposite ends of the inner shell assembly 200 are an inner end and an outer end, respectively. The inner end is used for cooperating with the equipment, and the outer end does not cooperate with the equipment. The third shell 23 covers the outer end face and the two side end faces of the inner shell assembly 200, and a mounting gap is left between the third shell 23 and the inner shell assembly 200. The third shell 23 is provided with heat dissipation holes 2301. The top and bottom of the third shell 23 are both open.

[0056] The mounting guide rail 224 is arranged in the mounting gap along the direction from the inner end to the outer end of the inner shell assembly 200.

[0057] The air outlet 2201 and the heat dissipation hole 2301 are arranged close to each other, which can shorten the flow path of the airflow, and the heat dissipation speed is faster, so that the heat dissipation efficiency is ensured, and the problem of overheating of the compressor assembly 24 is reduced.

[0058] The inner shell assembly 200 and the third shell 23 surround and protect the compressor assembly 24, so as to ensure the safety of the equipment and reduce noise transmission. The airflow for heat dissipation can enter the inner cavity from the air inlet 2101 at the top of the inner shell assembly 200, pass through the compressor assembly 24 and take away heat, and then be discharged from the air outlet 2201 at the bottom to the heat dissipation gap 230, and then be discharged through the heat dissipation hole 2301 on the third shell 23.

[0059] The shell assembly adopts a modular design, the inner shell assembly 200 and the third shell 23 can be installed on the equipment as a whole, can be integrally detached from the equipment, and can be guided by the mounting guide rail 224, so as to form a modular installation mode. The shell assembly also forms the heat dissipation gap 230 by using the mounting gap between the inner shell assembly 200 and the third shell 23, so as to fully utilize the space while ensuring the normal heat dissipation performance of the compressor. The modular disassembly mode of the shell assembly greatly facilitates the later maintenance of the compressor module.

[0060] When mounted on the equipment, the heat dissipation gap 230 is surrounded between the inner shell assembly 200, the third shell 23 and the equipment, and the equipment participates in surrounding the heat dissipation gap 230, so as to fully utilize the structure of the shell assembly and the equipment. After the shell assembly is detached from the equipment, the heat dissipation gap 230 becomes an open structure.

[0061] The air outlet 2201 and the heat dissipation hole 2301 are arranged close to each other, which can shorten the flow path of the airflow, and the heat dissipation speed is faster, so that the heat dissipation efficiency is ensured, and the problem of overheating of the compressor assembly 24 is reduced.

[0062] With reference to Figure 2 The left and right ends of the shell assembly are one inner end and the other outer end.
