Abstract
The application provides a compressor, comprising: a rear shell body, a first side of which is provided with a power module, and a second side of which forms a refrigerant flow channel; a sub-bearing seat, which is covered in a central region of the second side of the rear shell body; and a flow guide cover, which is fixed to the second side of the rear shell body and partially surrounds a side surface of the sub-bearing seat; wherein the rear shell body, the sub-bearing seat and the flow guide cover jointly form the refrigerant flow channel, which comprises at least a first sub-flow channel that penetrates the sub-bearing seat and a second sub-flow channel that surrounds one side of the sub-bearing seat. The compressor of the application increases the contact area between the refrigerant and the sub-bearing seat by arranging the flow guide cover on the rear shell body of the compressor and arranging the refrigerant flow channel inside and outside the sub-bearing seat, thereby improving the heat dissipation effect of the power module and the heat generating devices such as capacitors near the sub-bearing seat.
