Abstract:
Provided is a screw compressor (100), comprising: a housing (101), a fluid channel (140), and a silencing structure (320, 520, 620). The housing (101) is provided with a compression cavity (105); the fluid channel (140) is located in the housing (101), a first end (311) of the fluid channel (140) is communicated with the outside of the compressor (100), and a second end (312) of the fluid channel (140) is communicated with the compression cavity (105); the silencing structure (320, 520, 620) is arranged on the outer side of the fluid channel (140), the silencing structure (320, 520, 620) comprises at least one cavity (308, 408, 508, 608, 708, 808, 908, 1008, 1108, 1208), and the at least one cavity (308, 408, 508, 608, 708, 808, 908, 1008, 1108, 1208) is communicated with the fluid channel (140). The silencing structure (320, 520, 620) is arranged at the fluid channel (140) of the screw compressor (100), so that the effect of pressure changes on external pipelines connected to the fluid channel (140) can be reduced.
