Description

Technical Field

[0001] The utility model relates to the field of automobile water pumps, and more specifically to a heat dissipation structure of an automobile water pump. Background Art

[0002] In the cylinder of a car engine, in order to better cool the engine, it is necessary to lay multiple water channels for cooling water circulation, which are connected to the radiator (commonly known as the water tank) placed at the front of the car through water pipes to form a large water circulation system.

Therefore, the heat dissipation efficiency of the water pump is low. After working for a long time, the water pump will be insufficient due to the high temperature, affecting the flow of internal coolant, and then causing the engine temperature to be too high.
