Problems solved by technology

[0003] Most of the electronic water pumps on the market now have a self-cooling circulation system. Its function is to take away the heat generated by the motor and the controller when the coolant flows inside the electronic water pump to achieve the purpose of cooling. However, the structure of the electronic water pump is often The controller is installed directly behind the stator and rotor, which makes the overall size of the product larger and cannot meet the application environment with high requirements for space layout; generally only one cooling channel is set in the housing of the electronic water pump, and the cooling liquid flows from front to back. In the middle, it first passes between the stator and the rotor to take away part of the heat generated by the stator and rotor, and then passes through the controller. At this time, the temperature of the coolant has risen to a certain extent compared with the initial stage, so the cooling effect of the controller not ideal

Abstract

The invention discloses an electronic water pump device of an automobile. The electronic water pump device comprises a shell, an impeller, a stator, a rotor and a controller, wherein the stator and the rotor are mutually waterproof through the sealing connection of a waterproof sleeve and the shell, and the rear part of the shell is provided with a bearing base. The electronic water pump device is characterized in that a sealing control cabin is fixedly arranged at the side part of the shell; the controller is electrically connected with the stator through a lead; a central shaft hole is formed in a rotating shaft of the rotor; a first cooling channel and a second cooling channel are arranged in the shell; the first cooling channel is communicated with a side water outlet hole of the impeller and sequentially passes through an inner water through hole and an inner water through cavity; the inner water through cavity is communicated with the central shaft hole; the second cooling channel is communicated with the side water outlet hole of the impeller and sequentially passes through a first outer water through hole, an outer water through cavity, an outer water through groove and a second outer water through hole; and the second outer water through hole is communicated with the central shaft hole. The electronic water pump device has the advantages that the overall size is small, the two cooling channels can independently cool, the cooling effect on all parts of the electronic water pump is good, and the overall working performance is improved.

Description

technical field [0001] The invention relates to a water pump device, in particular to an electronic water pump device for automobiles. Background technique [0002] The automotive thermal management system is mainly from the perspective of system integration and overall planning, coordinating the relationship between heat, engine and vehicle. The purpose of environmental protection and energy saving; the electronic water pump is an important part of the system, which mainly drives the impeller through the controller to drive the rotation of the stator and rotor to circulate the coolant in the entire system to achieve the purpose of cooling and heating; but the electronic water pump works by itself The heat generated during this period is also a major technical problem that we as product developers need to solve. [0003] Most of the electronic water pumps on the market now have a self-cooling circulation system. Its function is to take away the heat generated by the motor a...
