Problems solved by technology

First of all, the structure of the technical solution is complex, and the axial length of the automotive electronic water pump becomes longer due to the need to set a water-proof rear chamber to dissipate heat from the controller, which is not conducive to the layout on the vehicle; secondly, between the annular extension section and the pump body It is necessary to set a water-proof sealing ring. When the electronic water pump is used for a long time, the sealing ring is prone to leakage after aging

Abstract

The invention provides an automobile electronic water pump, which belongs to the technical field of automobile water pumps. An automotive electronic water pump, comprising a pump body, a pump cover, a stator, a water barrier, a rotating shaft, a rotor and a controller, the pump cover is connected to the pump body, the stator is inserted into the pump body, and the water barrier is inserted into the stator, The rotating shaft is set in the water-proof sleeve and is fixedly connected with the water-proof sleeve. The rotor is set on the rotating shaft. The side of the stator away from the pump cover is provided with a controller bracket. A first gap is arranged between the bottoms of the sleeves, and a thermal conductive glue is arranged in the first gap, and the thermal conductive glue abuts against the controller and the water-proof sleeve respectively. The present invention realizes the active cooling of the controller without substantially increasing the axial length of the electronic water pump of the automobile. At the same time, the solution reduces the use of sealing rings and reduces the risk of liquid leakage of the electronic water pump of the automobile.

Description

An automotive electronic water pump technical field The invention belongs to the technical field of automobile water pumps, in particular to a kind of automobile electronic water pump. Background technique The main components of automobile electronic water pump include controller, drive motor and overcurrent parts, drive motor and overcurrent parts. The flow components constitute the actuator of the automotive electronic water pump. The controller cooperates with the drive motor to control the water pump. The automotive electronic water pump is in In traditional vehicles, it can provide power output for the engine, turbocharger and intercooler cooling circuit, and in new energy vehicles It can provide power output for the cooling circuit of main heating parts such as motor, electronic control and battery. The heat dissipation of the controller affects the service life of the automobile electronic water pump, and the heat dissipation mode of the current automobile ele...
