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

Embodiment Construction

[0035] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the figure). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly. In addition, in the present invention, descriptions such as "first", "second", "one" and so on are used for descriptive purposes only, and should not be understood as indicating or implying their relative importance or implicitly indicating the indicated technical features quantity. Thus, the features defined as "first" and "second" may explicitly or implicitly include at least one of these features. In the description of the present invention, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined. In the present invention, unl...

Abstract

The invention provides an automobile electronic water pump, and belongs to the technical field of automobile water pumps. An automobile electronic water pump comprises a pump body, a pump cover, a stator, a waterproof sleeve, a rotating shaft, a rotor and a controller, the pump cover is connected with the pump body, the stator is inserted into the pump body, the waterproof sleeve is inserted into the stator, the rotating shaft is arranged in the waterproof sleeve and fixedly connected with the waterproof sleeve, the rotor is arranged on the rotating shaft in a sleeving mode, and a controller support is arranged on the side, away from the pump cover, of the stator. The controller is arranged on the controller support, a first gap is formed between the controller and the bottom of the waterproof sleeve, heat-conducting glue is arranged in the first gap, and the heat-conducting glue abuts against the controller and the waterproof sleeve. Under the condition that the axial length of the automobile electronic water pump is basically not increased, active heat dissipation of the controller is achieved, meanwhile, the use of a sealing ring is reduced, and the liquid leakage risk of the automobile electronic water pump is reduced.

Description

technical field [0001] The invention belongs to the technical field of automobile water pumps, and in particular relates to an automobile electronic water pump. Background technique [0002] The main components of the automotive electronic water pump include the controller, drive motor and over-current components. The drive motor and over-current components form the actuator of the automotive electronic water pump. The controller and the drive motor cooperate to control the water pump. The automotive electronic water pump can be The engine, turbocharger, and intercooler cooling circuit provide power output. In new energy vehicles, it can provide power output for the cooling circuit of main heat-generating parts such as motors, electronic controls, and batteries. [0003] The heat dissipation of the controller affects the service life of the automotive electronic water pump. At present, the heat dissipation methods of the automotive electronic water pump are mainly divided in...
