[0002] Oil-free compressors refer to compressors that do not use lubricating oil in the compressor cylinder. The crankcase of a fully oil-free compressor is a dry structure, and its connecting rod large and small holes, and the front and rear main bearings of the crankshaft generally use double-port sealed grease-containing ball bearings. Since no lubricating oil comes into contact with the compressed gas source during operation, the discharged gas does not contain oil or gas.

[0003] For example, the utility model patent with announcement number CN209041063U discloses an oil-free compressor air cooler, which cools the high-temperature and high-pressure gas by passing the high-temperature and high-pressure gas into the inner channel of the air cooling core, and the fins of the outer channel dissipate the heat on the inner channel. However, the expansion space of the high-temperature and high-pressure gas in the inner channel of the air cooling core is limited, and the heat dissipation effect of the device on the inner channel is poor, resulting in a relatively general cooling effect. Therefore, a cooler for an oil-free compressor is urgently needed to be developed. Utility Model Content
