Abstract
The invention discloses an automobile electronic water pump comprising a metal pump shell and a pump head. A first chamber and a second chamber separated from the first chamber are arranged in the metal pump shell. A stator, a rotor and a shaft core are sequentially arranged inside the first chamber from outside to inside. A controller electrically connected with the stator is fixedly arranged in the second chamber. The automobile electronic water pump is characterized in that a metal separation plate is arranged between the first chamber and the second chamber, the controller is fixedly arranged on the metal separation plate, and an insulating thermal conductive adhesive is arranged between the controller and the metal separation plate. The automobile electronic water pump has the advantages that heat generated by the controller can be transmitted onto the metal separation plate through the insulating thermal conductive adhesive in time, the heat is rapidly dissipated through the metal separation plate, the heat of the controller and the second chamber where the controller is located is brought away, the highest using temperature of the automobile electronic water pump is greatly increased, and thus the performance of an electric automobile is improved.
Description
Technical field
The present invention relates to a kind of water pump structure, especially a kind of electronic water pump for automobile.
Background technology
As country is to the more and more higher of environmental requirement, electric automobile is just developed with the speed maked rapid progress.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 is poly- will to cause related components to fail, or even spontaneous combustion, therefore electric motor car must design cooling system and related components are entered
Row cooling, but, 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 by 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 cannot 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
The technical problems to be solved by the invention are to provide a kind of preferable electronic water pump for automobile of controller radiating effect.
The present invention solve the technical scheme that is used of above-mentioned technical problem for：A kind of electronic water pump for automobile, including metal pump
Shell and pump head, are provided with mutually isolated first chamber and second chamber, in described first chamber in described metal pump case
Stator, rotor and shaft core are disposed with outer, are fixedly installed in described second chamber and are electrically connected with described stator
The controller for connecing, is provided with metal division board between described first chamber and described second chamber, described controller is consolidated
Surely it is arranged on described metal division board, insulating radiation is provided between described controller and described metal division board
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 pressure of the pressure of the coolant of impeller outlet cavity far above impeller inlet cavity coolant, due to
Fluid always flows to the characteristic at low-pressure from 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, after increased the second drip ring and third gear water ring, considerably increases 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, the advantage of the invention is that the heat that controller is produced can in time pass through insulating radiation glue
It is transferred on metal division board, is distributed heat rapidly by metal division board, takes away controller and where controller second
Heat in chamber, substantially increases the maximum operation (service) temperature of electronic water pump for automobile, so as to improve the performance of electric automobile.
