Description
Technical field
This utility model relates to a kind of electronic water pump.
Background technology
Along with the development of new energy vehicle industry, needing the parts of cooling to get more and more, total cooling power demand presents increase tendency, and this needs exist for the circular flow that powerful electronic water pump provides bigger, to promote the cooling power of system.Heat dissipation environment is required harsher by the control module of high powered water pump, solve this difficult problem at present and generally use internal or external fan air blast cooling, this can cause electronic water pump overall volume to increase with the increase of power, reduces the power density of electronic water pump motor, increases car load assembly difficulty.
Utility model content
The purpose of this utility model is to provide the electronic water pump of a kind of power density improving motor.
For achieving the above object, the technical scheme of this utility model electronic water pump is: electronic water pump includes pump head and the pump housing, pump head includes pump head chamber, impeller and pump head chamber base, the pump housing includes motor and control module, described control module is between described pump head and motor, control module include panel and install pedestal, panel be arranged on installation pedestal near the side of motor, install pedestal include the dividing plate for separating pump head and panel.
Described dividing plate is provided with the cooling water channel communicated with described pump head chamber near the side of pump head.
Described installation pedestal includes that ring is located at the outer land of dividing plate periphery, and outer shroud platform convex, for the both sides of dividing plate, is installed pedestal and 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 inlet and outlet, and described inlet and outlet lays respectively at water inlet and the both sides of outlet axis projection line in described pump head chamber.
Described cooling water channel is loop configuration.
Described installation pedestal is connected with pump head chamber base and motor housing by flange arrangement respectively.
On dividing plate, the main heating module contact position with panel is provided with diversion channel, and described diversion channel communicates with pump head chamber.
Described dividing plate is aluminium sheet.
The beneficial effects of the utility model are: control module be located between pump head and motor, be spaced by dividing plate between panel and pump head, and the coolant in pump head chamber can cool down control module, without separately setting air cooling equipment, compact conformation, saves space, improves the power density of motor.
Further, cooling water channel is set on front side of dividing plate, coolant is played guide functions, it is possible to cool down for panel.
Further, the inlet and outlet of cooling water channel lays respectively at water inlet and the both sides of outlet axis projection line in pump head chamber, when the impeller in pump head starts running, pressure differential will be there is between inlet and outlet, the coolant promoting pump head intracavity forms flowing by cooling water channel, thus improves cooling effectiveness.

Detailed description of the invention
Below in conjunction with the accompanying drawings embodiment of the present utility model is described further.
The specific embodiment of electronic water pump of the present utility model, as shown in Figures 1 to 5, electronic water pump includes pump head 1 and the pump housing front and back arranged, pump head includes the pump head chamber for driving coolant to circulate, impeller 17 and pump head chamber base, pump head chamber has water inlet 11 and outlet 12, and the pump housing includes motor 3 and control module 2.Motor 3 is by magnetic driving device transmission, and magnetic driving device includes outer magnetic ring rotor 15 and internal magnetic ring rotor 16, and above structure is prior art.Control module 2 is arranged between pump head 1 and motor 3, control module 2 includes panel and installs pedestal, panel is arranged on the rear side installing pedestal, install that pedestal includes erecting for separating the dividing plate 201 of pump head 1 and motor 3 and being looped around the outer land 202 of dividing plate 201 periphery, the outer land 202 installing pedestal is front and back separated by dividing plate 201, and outer land 202 protrudes from both sides before and after dividing plate 201.The outer land 202 installing pedestal is connected with pump head chamber base by forward flange structure, is connected with motor housing by rear flange structure.The front side of dividing plate 201 is provided with outer magnetic ring mounting groove 21, the cooling water channel 22 caved in backward it is provided with between outer magnetic ring mounting groove 21 and outer land 202, cooling water channel 22 is water annulus, and pump head chamber base is provided with the import 13 for making cooling water channel 22 communicate and outlet 14 with pump head chamber；The rear side of dividing plate 201 is provided with the panel mounting groove 23 for installing panel.Being provided with the diversion channel 24 roughly the same with corresponding heating module profile at dividing plate 201 with the main heating module contact position of panel, diversion channel 24 communicates with pump head chamber, and the opening of diversion channel 24 is positioned at the front side of dividing plate 201, and protruding backward.Import 13 and outlet 14 lay respectively at the both sides of water inlet 11 and outlet 12 axis projection line, when the impeller in pump head starts running, pressure differential is there is between import 13 and the outlet 14 of cooling water channel, the coolant promoting pump head intracavity forms flowing by cooling water channel, thus cools down panel.In the present embodiment, dividing plate uses the aluminium sheet that heat conductivility is good.
