The bottom of the upper shell is fixedly connected to the lower shell, and the top of the upper shell is provided with a heat dissipation assembly. The heat dissipation assembly includes an aluminum plate, a coating groove and an adhesive groove. The bottom of the aluminum plate is provided with a coating groove, and the bottom of the aluminum plate is provided with an adhesive groove.

[0004] The device solves the problem of poor heat dissipation of the traditional automobile water pump housing during operation by adding an aluminum plate to the outside of the upper housing. Since thermal grease is applied between the aluminum plate and the upper housing, when the temperature of the water pump housing rises, the heat will be transferred to the aluminum plate through the thermal grease, and then the aluminum plate will dissipate the heat, thereby accelerating the cooling, greatly improving the heat dissipation efficiency of the water pump housing during operation. The overall structure is simple, the functionality is strong, the heat dissipation effect is good, and the housing is prevented from being overheated for a long time. The device dissipates heat from the water pump housing through the heat dissipation component, but the device only seals the water pump through the first sealing ring, and the sealing structure is prone to water leakage in the water pump.
