Problems solved by technology

However, due to space and cost constraints, the diameter of the hollow shaft is limited, and the diameter of the via hole in the middle is very small, resulting in very little flow that can flow to the control device on the back PCB
In addition, since the fluid will pass through the motor before reaching the PCB control device and absorb the heat of the motor, the actual cooling effect on the PCB control device is limited.

Abstract

The invention relates to an automobile electronic water pump and an automobile. The automobile electronic water pump comprises a pump shell, a suction pipe arranged at the front end of the pump shelland a discharging pipe arranged on the side wall of the pump shell. A pump cavity is formed in the pump shell. The suction pipe and the discharging pipe communicate with the pump cavity. The water pump further comprises a motor, an impeller and an electronic control device, wherein the motor is connected with the pump shell through a pump shaft and is arranged in the pump cavity, the impeller is connected with the pump shaft, and the electronic control device is connected with the motor and arranged outside the pump shell. The pump shell is provided with a cooling cavity, and the cooling cavity is close to the electronic control device. The cooling cavity is directly arranged near a PCB control device, the cooling liquid flowing process is saved, and the effect of rapid heat dissipation and cooling is achieved; and the automobile electronic water pump is simple in structure and convenient to operate.

Description

technical field [0001] The invention relates to an automobile electronic water pump and an automobile, belonging to the technical field of water pump design. Background technique [0002] At present, the wet rotor electronic water pump is mainly used in the market. In this structure, the PCB control device is arranged at the other end away from the hydraulic part of the pump, and the fluid flows through the hollow shaft to the heat dissipation device of the PCB control device or nearby to take away the PCB heat. However, due to space and cost constraints, the diameter of the hollow shaft is limited, and the diameter of the via hole in the middle is very small, resulting in very little flow that can flow to the control device on the back PCB. In addition, since the fluid will pass through the motor before reaching the PCB control device, thereby absorbing the heat of the motor, the actual cooling effect on the PCB control device is limited. Contents of the invention [000...
