Description

Technical Field

[0001] The invention relates to an air compressor cooling structure. Background Art

[0002] A screw compressor is a positive displacement gas compression machine whose working volume performs a rotational motion. The compression of the gas is achieved by the change of volume, and the change of volume is achieved by the rotational motion of a pair of rotors of the compressor inside the casing. When existing screw compressors compress the air, the discharged air flow has a higher temperature due to the rotational compression of the screw. When high-temperature air flow needs to be discharged, the compressed discharged air flow does not need to be cooled and can be used normally. However, when in a specific usage environment, the discharged compressed air needs to be cooled. Existing screw compressors generally have a structure that discharges after a cooling system, or directly delivers the compressed air flow without cooling. It cannot be adaptively selected according to actual needs to deliver after cooling or directly deliver without cooling. The structure has poor flexibility and its scope of use is greatly limited.
