Housing arrangement for stator of electric motor of electric vehicle, has hollow cylindrical part and pipe combinedly separating hollow space, which forms channel for cooling liquid to cool arrangement

摘要

The housing arrangement has a hollow cylindrical part (12) and a pipe (30) combinedly separating a hollow space (20), which forms a channel for a cooling liquid to cool the arrangement. The pipe surrounds the hollow cylindrical part. The hollow cylindrical part consists of aluminum and the pipe consists of steel. A sealing ring (32) is formed between the pipe and the hollow cylindrical part. The pipe covers a groove formed in the cylindrical part, where a sealing material i.e. silicon, is arranged in the groove.
