Title:
SCREW COMPRESSOR AND COMPRESSOR BODY THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/024514
Kind Code:
A1
Abstract:
A screw compressor and a compressor body thereof. The compressor body comprises a shell (100); a rotor cavity (110) is formed inside the shell (100); the shell (100) is provided with a refrigerant flow channel (200) around the rotor cavity (110); the refrigerant flow channel (200) is close to the wall surface of the rotor cavity (110) and is used for circulating a refrigerant; and when a rotor is provided in the rotor cavity (110), the refrigerant and the rotor can conduct heat exchange by means of the wall surface of the rotor cavity (110), to cool the rotor, so that deformation of the rotor is reduced, the operating range of the compressor can be effectively widened, and the applicability of the compressor is improved.
