Abstract
The utility model discloses a kind of electronic water pump for automobile, including metal pump case and pump head, mutually isolated first chamber and second chamber is provided with metal pump case, stator, rotor and shaft core are disposed with outer in first chamber, the controller electrically connected with stator is fixedly installed in second chamber, feature is that metal division board is provided between first chamber and second chamber, and controller is fixedly installed on metal division board, and insulating radiation glue is provided between controller and metal division board；Advantage is that the heat that controller is produced can be transferred on metal division board by insulating radiation glue in time, heat is distributed rapidly by metal division board, take away the heat in the second chamber where controller and controller, the maximum operation (service) temperature of electronic water pump for automobile is substantially increased, so as to improve the performance of electric automobile.
Description
Technical field
The utility model is related to a kind of water pump structure, especially a kind of electronic water pump for automobile.
Background technology
With more and more higher of the country to environmental requirement, electric automobile is just developed with speed with rapid changepl. never-ending changes and improvements.Electric automobile
Battery, motor, electric machine controller, the parts such as charger can all produce substantial amounts of heat, heat one during work
Direct product will be poly- to cause related components to fail, or even spontaneous combustion, therefore electric car must design cooling system and related components are entered
Row cooling, still, because electric automobile eliminates traditional explosive motor, so also cannot provide cold by mechanical water pump
But, electronic water pump for automobile is just arisen at the historic moment in this context, in existing electronic water pump for automobile, typically passes through controller control
Rotor is cooperated with stator, and impeller is rotated, and controller is arranged in the chamber mutually isolated with stator and rotor；So
And, controller can produce amount of heat when working, once can not radiate in time will influence controller performance, or even to controller
Itself cause to damage, therefore, the maximum operation (service) temperature of electronic water pump for automobile is general at 85 °C or so, to the hair of electric automobile performance
Tool is waved to have certain limitations.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of preferable automotive electronics water of controller radiating effect
Pump.
The utility model solve the technical scheme that is used of above-mentioned technical problem for：A kind of electronic water pump for automobile, including gold
Belong in pump case and pump head, described metal pump case and be provided with mutually isolated first chamber and second chamber, the first described chamber
Indoor be disposed with stator, rotor and shaft core, described second chamber within outer is fixedly installed and described stator
The controller of electrical connection, metal division board, described control are provided between described first chamber and described second chamber
Device is fixedly installed on described metal division board, and being provided with insulation between described controller and described metal division board dissipates
Hot glue.
One end of described rotor has been wholely set impeller, and is disposed with from the inside to the outside on the end face of described impeller
One drip ring and the second drip ring, described pump head are provided with third gear water ring, described third gear water ring insertion it is described the
In groove between one drip ring and the second described drip ring.When impeller operation, impeller does work to coolant, makes coolant
Pressure rise, so that the pressure of the coolant of impeller outlet cavity is far above the pressure of impeller inlet cavity coolant, due to
Fluid always flows to the characteristic at low-pressure at high pressure, and part coolant will pass through impeller protecgulum from impeller outlet cavity again
Gap between plate and pump head flow back into impeller inlet cavity, and this part coolant will not be parked in import cavity and the outlet of impeller
Circulated before cavity, impeller is idle work to this part coolant work done, and the loss of this Partial Power is pump
Volumetric loss, is added after the second drip ring and third gear water ring, is considerably increased coolant and is flow back into from impeller outlet cavity
The resistance of impeller inlet cavity, is also considerably reduced the coolant that impeller inlet cavity is flow back into from impeller outlet cavity
Amount, so as to reduce the volumetric loss of electronic water pump for automobile, improves the running efficiency of electronic water pump for automobile.
It is provided with the first self-lubricating plain bearing between one end of described rotor and described shaft core, described rotor
Be provided with the second self-lubricating plain bearing between the other end and described shaft core, described the first self-lubricating plain bearing with it is described
The second self-lubricating plain bearing between form cooling chamber.The noise produced when rotor is rotated is reduced, rotor rotation is greatly reduced
When and shaft core between abrasion, increase electronic water pump for automobile service life.
Compared with prior art, it can be dissipated in time by insulation the utility model has the advantage of the heat that controller is produced
Hot glue is transferred on metal division board, is distributed heat rapidly by metal division board, where taking away controller and controller
Heat in second chamber, substantially increases the maximum operation (service) temperature of electronic water pump for automobile, so as to improve the performance of electric automobile.
