Description
Technical field
This utility model is related to a kind of electronic water pump with interior circulation cooling circuit.
Background technology
Existing electronic water pump cooling structure, typically gets out through hole at mandrel center, the through hole isometrical with wheel bottom
It is corresponding, higher-pressure region is formed in wheel bottom, low-pressure area is formed at impeller eye, so as to produce pressure differential, current are formed, to water
The parts such as bearing, panel in pump operation process are cooled down.But this structure needs to punch mandrel hole, processing cost
Height, in addition the mandrel diameter of axle is also larger, can increase the overall volume of water pump, and the logical heart axial wall thickness after punching is relatively thin, compares in making
Difficulty, yield rate is not high.

But the good electronic water pump with interior circulation cooling circuit of effect.
This utility model solves the technical scheme that its technical problem adopted：A kind of electricity with interior circulation cooling circuit
Sub- water pump, including shell body, the inner housing of shell body upper end is fixed on, the core that inner housing is stretched out in upper end is fixed with shell body
Axle, the rotor assembly and impeller of electronic water pump are rotated by sliding shaft sleeve and are located on mandrel, and stator module sets around rotor assembly
Shell body inwall is put and be fixed on, the uniform axial groove of at least three circumferences is offered on described sliding shaft sleeve inwall, it is described
Impeller and inner housing between gap, the gap between stator module and rotor assembly, between rotor assembly and mandrel between
Gap and axial groove constitute complete interior circulation cooling circuit.
Preferably, four uniform axial grooves of circumference are offered on described sliding shaft sleeve inwall.
Further, water pump cover is sealed and installed with described inner housing, shell body bottom end seal is fixed with bonnet, is located at
Shell body bottom is provided with the panel of control water pump operation, and hanging wire terminal is sealedly connected between stator module and panel.
The beneficial effects of the utility model are：This utility model in water pump operation, the stream flowed by interior circulation loop
Body is cooled down to electronic water pump inside, so as to improve reliability and the life-span of electronic water pump.There is the cunning of axial groove simultaneously
Moving axis set is processed using mould, easy to make, high yield rate.
Description of the drawings
Below in conjunction with the accompanying drawings this utility model is further illustrated with embodiment.
