摘要： An intake air distribution apparatus and a compressor comprising same. The intake air distribution apparatus (100) comprises a flow guide unit (120); the flow guide unit (120) is configured to guide a part of a fluid entering a housing of the compressor (10) to flow along a predetermined route; the flow guide unit (120) comprises a body (121); an inlet channel (150) and an outlet channel (125) are provided in the body (121); the inlet channel (150) is configured to introduce part of the fluid in the housing of the compressor (10) into the flow guide unit (120); the outlet channel (125) is configured to enable part of the fluid to flow out in a predetermined azimuthal orientation. The intake air distribution apparatus can effectively introduce the fluid to a required area by means of the flow guide unit (120), such that an oil circulation rate is controlled, and components in the required area can be cooled.
