[0002] As one of the indispensable components of new energy vehicles, the water pump shoulders the important mission of cooling the battery, motor, and air conditioner. Every component is crucial. In order to reduce the assembly steps of the process, the casing can adopt an integral injection molding solution.

[0003] For the existing water pump casing, such as a vertical water pump special casing disclosed in the utility model patent with the application number 202223140277.3, its main structure includes a casing structure and a cooling and dust-proof structure. The casing structure includes a first casing and a second casing. The first casing is slidably fixed to the second casing. The cooling and dust-proof structure includes a heat dissipation component and a filter screen. The heat dissipation component is arranged inside the second casing, and the filter screen is arranged on one side of the second casing; during use, the first casing is slid into the second casing. At this time, the slider is slidably connected to the chute. When sliding to the lowest end, the rotating rod is rotated. Through the rotation of the rotating rod and the fixed block, the first screw rod is fixed to the second casing. When the water pump needs to be cooled, the cooling fan is turned on. At this time, the hot air inside the water pump passes through two heat dissipation holes and is blown out by the cooling fan for rapid heat dissipation. Through the setting of the filter screen, it can prevent external dust from entering the water pump. When the filter screen needs to be replaced, the second rotating block is rotated to quickly remove the second screw rod.
