Description

Electronic water pump
Technical field
The present invention relates to a kind of electronic water pump.
Background technique
Along with the development of new energy vehicle industry, need the component of cooling to get more and more, total cooling power demand presents increase tendency, and this just needs powerful electronic water pump to provide larger circular flow, with the cooling power of elevator system.The control module of high powered water pump requires harsher to heat dissipation environment, this difficult problem of current solution adopts internal or external fan forced air cooling usually, this can cause electronic water pump overall volume to increase with the increase of power, reduce the specific power of electronic water pump motor, increase car load assembling difficulty.
Summary of the invention
The object of the present invention is to provide a kind of electronic water pump improving the specific power of motor.
For achieving the above object, the technological scheme of electronic water pump of the present invention is: electronic water pump comprises pump head and the pump housing, pump head comprises pump head chamber, impeller and pump head chamber base, the pump housing comprises motor and control module, described control module is between described pump head and motor, control module comprises control panel and mounting base, and control panel is arranged on the side of mounting base near motor, and mounting base comprises the dividing plate for separating pump head and control panel.
Described dividing plate is provided with the cooling water channel communicated with described pump head chamber near the side of pump head.
Described mounting base comprises the outer land that ring is located at dividing plate periphery, and outer shroud platform convex is for the both sides of dividing plate, and mounting base is provided with outer magnetic ring mounting groove near the side of pump head, and described cooling water channel is between outer magnetic ring mounting groove and outer land.
Described cooling water channel is the enclosed construction with import and outlet, and described import and outlet lay respectively at the water intake in described pump head chamber and the both sides of water outlet axis projection line.
Described cooling water channel is loop configuration.
Described mounting base is connected with motor housing with pump head chamber base respectively by flange arrangement.
Dividing plate is provided with diversion channel with the main heating module contacting point of control panel, and described diversion channel communicates with pump head chamber.
Described dividing plate is aluminium sheet.
The invention has the beneficial effects as follows: control module be located between pump head and motor, separated between control panel and pump head by dividing plate, the cooling liquid in pump head chamber can cool control module, without the need to separately establishing air cooling equipment, compact structure, saves space, improves the specific power of motor.
Further, cooling water channel is set on front side of dividing plate, guide functions is risen to cooling liquid, can cool for control panel.
Further, import and the outlet of cooling water channel lay respectively at the water intake in pump head chamber and the both sides of water outlet axis projection line, when impeller entry into service in pump head, pressure difference will be there is between import and outlet, promote that the cooling liquid in pump head chamber forms flowing by cooling water channel, thus improve cooling effectiveness.
