The invention provides a compressor housing, an air cycle machine housing and an air cycle machine. The compressor housing comprises an air inlet pipe, a wheel cover, a circular ring section and a vortex pipe which are sequentially connected, the inner ring radius of the circular ring section is r0, a first boundary line is formed at the intersection position of the circular ring section and the wheel cover on the inner circumferential face, a second boundary line is formed at the intersection position of the wheel cover and the air inlet pipe on the inner circumferential face, a plane which passes through the first boundary line and is perpendicular to the central axis of the wheel cover is a first plane, the distance between the second boundary line and the first plane is z1, any plane is taken between the second boundary line and the first plane, the distance between the any plane and the first plane is zi, the intersecting line of the any plane and the inner circumferential surface of the wheel cover is a circle, the radius is ri, the molded line y of the wheel cover is equal to ri/r0, the variable x is equal to zi/z1, the variable y is equal to ax<6> - bx<5> + cx<4> - dx<3> + ex<2> - fx + g, a is equal to 4.1-6.6, b is equal to 15-22, c is equal to 20-30, d is equal to 14-20, e is equal to 5-8, f is equal to 1-2.5, and g is equal to 0.5-1.5. According to the compressor housing, the structure of a compressor can be optimized, the airflow loss is reduced, and the performance of the compressor is improved.
