According to the announcement by the National Intellectual Property Office, Great Wall Motors Co., Ltd. applied for a patent called "Electronic Water Pump and Vehicle," with publication number CN117345651A, filed on June 2022.

The patent abstract shows that the invention provides an electronic water pump and vehicle. The electronic water pump is equipped with a cooling flow channel, and the stator of the electronic water pump has a fluid channel connected to the cooling flow channel. By setting the fluid channel inside the stator and connecting it to the cooling flow channel, the fluid in the cooling flow channel can flow through the fluid channel and exchange heat with the stator. This allows the stator to operate at an appropriate temperature, preventing pump body burnout faults and extending the lifespan of the electronic water pump. It has good practicality.
