[0018] The circular chamber 8 of the shell 1 is used to install components such as rotors and coils. Several circles of steps 9 are concentrically arranged at the upper opening of the circular chamber 8. The outer diameter of the steps 9 gradually decreases from bottom to top, except Except for the uppermost step 9, the upper ends of the other steps 9 are all covered with sealing rings, and a matching upper cover is installed on the upper end of the shell 1. The upper cover has a water outlet and is protected by multi-layer sealing rings, which can effectively prevent cooling water passages from cooling. 6 of the water goes into the circular chamber 8 . The inner wall of the cooling water channel 6 is evenly arranged with several metal vertical bars 7, the metal vertical bars 7 can increase the strength of the cooling water channel 6, so that the thickness between the inner wall of the cooling water channel 6 and the outer wall of the casing 1 can be relatively thinner, reducin...
