Air cooling structure of air compressor and air compressor

The utility model provides an air cooling structure of an air compressor and the air compressor, and belongs to the field of air compressors, the air cooling structure of the air compressor comprises an air inlet channel, a cooling air channel and an air outlet channel which are arranged on the air compressor and are connected in sequence, and the cooling air channel comprises a pressing end air channel, a connecting air channel and a vortex end air channel which are connected in sequence. Cooling air enters from the air inlet channel, firstly passes through the pressure end air channel to cool the pressure end thrust bearing and the pressure end radial bearing, then enters the vortex end air channel through the connecting air channel to cool the vortex end radial bearing, and then flows into the air outlet channel to be exhausted from the interior of the air compressor. According to the air cooling structure of the air compressor, cooling air is not divided after entering the air compressor, all the bearings
