Problems solved by technology

Traditional electronic water pumps must separate the motor rotor and stator because the motor stator must not be in contact with the coolant, which increases the performance manufacturing requirements for the internal sealing system of the motor and reduces the reliability of the motor
At the same time, due to the relatively small flow of coolant entering the motor, the cooling effect is relatively poor, which affects the use of the electric control board

Embodiment Construction

[0030] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0031] In the present invention, unless stated to the contrary, the used orientation words such as "up, down, top, bottom" generally refer to the directions shown in the drawings or refer to the vertical, perpendicular or gravitational directions The terms used to describe the mutual positional relationship of the various components mentioned above. The distinction between "front end and rear end" is mainly based on the flow direction of the coolant. The end close to the coolant inlet of the casing is the front end, and the downstream end of the coolant flow direction or the end without coolant flow is the rear end of the casing.

[0032] Due to considerations ...

Abstract

The invention discloses an electronic water pump. The electronic water pump comprises a cylindrical housing (5), a pump cover (2) and a base (10) which are positioned at the two ends in the axial direction of the housing (5) separately; an impeller (3) close to the pump cover and an impeller drive motor close to the base are arranged in the housing; the electronic water pump further comprises an electronic control board (1); the electronic control board is mounted on the surface of the pump cover; and electric connecting wires (12) of the electronic control board are arranged on the peripheral wall of the housing to be connected with the impeller drive motor. According to the electronic water pump, the electronic control board is mounted on the surface, where a cooling liquid inlet is formed, of the pump cover, heat generated by the serious heating electronic control board can be taken away through heat transmission when a lot of cooling liquid flowing through the pump cover, the heat generation problem of the electronic control board is solved, and the service life of the electronic control board is prolonged.

Description

technical field [0001] The invention relates to the field of electronic water pumps, in particular to an electronic water pump. Background technique [0002] In the energy-saving environment, electronic cooling water pumps have the advantages of precise control and higher efficiency compared with traditional water pumps. Most modern high-end cars and electric vehicles use electronic water pumps to replace the original mechanical water pumps. These electronic water pumps are generally miniature Self-priming water pumps are used in water circulation, cooling or on-board water supply systems of some automobiles. [0003] The electronic water pump in the prior art adopts a brushless DC motor, low voltage, and high current, and the high current often causes serious heating of its electric control board. The traditional electronic water pump is placed on the rear end cover of the motor (the side of the base) near the end of the stator power line due to the wiring problems of the ...
