Document Type and Number:
WIPO Patent Application WO/2020/088293
Kind Code:
A1
Abstract:
Disclosed are an electric motor cooling assembly, an electric motor and a compressor. The electric motor cooling assembly comprises an inner shell and an outer shell. A mounting space adapted to an electric motor main body is formed inside the inner shell. The outer shell is sheathed outside the inner shell, with a cooling cavity being formed between the outer shell and the inner shell. The outer shell is provided with a cooling medium inlet and a cooling medium outlet, and a cooling medium is circulated in the cooling cavity through the cooling medium inlet and the cooling medium outlet. By means of the technical solution of the present disclosure, the cooling medium is circulated in the cooling cavity through the cooling medium inlet and the cooling medium outlet, the electric motor main body can be fully cooled, and the temperature of the electric motor main body can be uniform, thereby improving the efficiency of the electric motor and improving the energy efficiency of the compressor.
