Description

Technical Field

[0001] The utility model relates to the technical field of oxygen concentrators, in particular to a compressor heat dissipation device based on bionics. Background Art

[0002] Because internal compressors generate noise during operation, some oxygen concentrator designs often include encapsulation to reduce noise. However, during operation, the internal energy generated by the compressed air causes the compressor and the compressed air to continuously heat up. This excessive temperature not only shortens the compressor's lifespan but also causes a decrease in oxygen concentration. Therefore, a heat dissipation structure is needed to overcome this problem.

[0003] The heat dissipation structure used in existing compressors generally adds a radiator to the compressor's air outlet and installs a fan on the package to achieve the heat dissipation effect. Due to the large size of the radiator, the package volume increases accordingly, which not only makes the overall structure of the oxygen concentrator bloated, but also increases the manufacturing cost. Summary of the Invention

[0012] Furthermore, the air inlet connector and the air outlet connector are located at the same end of the air path base plate, and the cooling channel includes a first heat dissipation path and a second heat dissipation path that are connected in sequence;
