Water cooling circulating water channel structure of motor case for new energy electric automobile

The utility model discloses a water cooling circulating water channel structure of a motor case for a new energy electric automobile. The water cooling circulating water channel structure includes a first water channel group, a second water channel group, a third water channel group, a fourth water channel group, a water inlet and a water outlet. The water cooling circulating water channel structure enables the overall heat dissipation performance of a water cooling circulating motor case to be greatly improved whether the motor case is a one-piece water cooling circulating motor case or a split type water cooling circulating motor case, and enables the overall heat dissipation performance to be improved by 30% compared with a conventional water channel design model. In terms of a conventional water channel structure, heat dissipation is uneven and heat nodes are liable to gather together. The water cooling circulating water channel structure helps to overcome the above disadvantages. Therefore, a motor case can be even in overall heat dissipation, has useful functions, and is steady.
