[0034] In addition, the cooling water passing through the lower cooling water flow path can cool the first control board and the second control board together, and the lower cooling water flow path can serve as the cooling water flow path for the first control board and the second control board, thereby simplifying the structure and making it compact.

[0035] In addition, the cooling water passing through the upper cooling water flow path can cool both the first control board and the third control board, and the upper cooling water flow path can serve as the cooling water flow path for the first control board and the third control board, thereby simplifying the structure and making it compact.

[0036] In addition, the cooling water passing through the upper cooling water flow path can cool the first control plate, the third control plate and the fourth control plate together, and the upper cooling water flow path can also serve as the cooling water flow path of the first control plate, the cooling water flow path of the third control plate and the cooling water flow path of the fourth control plate, so that the structure is simple and can be compact.
