Critical component, the effect of cooling directly affects the performance of motor.
The cooling scheme of driving motor has air-cooled, water cooling and oil cold, and the advantage of oil-cooled motor is that cooling medium can be directly
It is contacted with winding, heat dissipation effect is more preferable.
However, inventor has found in the process of implementing the utility model, and in the cold scheme of first dynamo oil, some technologies
Only stator core part is cooled down without the cooling of stator winding end, some only cools down stator winding end
And core portion cannot be cooled down, the utility model realizes the cooling to stator core part and realizes again to stator
The cooling of winding overhang.Carrying out in cooling scheme to stator core part: some need is slotted in chassis cavity, it is difficult to be made
It is manufactured with efficient production technology, batch production technique is poor, while destroying the company for the cavity being connected with stator core outer ring
Continuous property, is unfavorable for the reliability of connection；Some need in stator core part open, such as application No. is
The Chinese patent of CN201520645900.1 will increase after aperture on iron core although oil liquid can be contacted directly with iron core
Iron core outer diameter reduces power density, while increasing the dosage of silicon steel, to increase cost.
Such as: application No. is the ends of the Chinese patent of CN201510819697A.X, mainly stator winding to be cooled down
Cooling component, the cooling component includes the cooling duct for cooling medium to be delivered to stator winding end, described cold
But the liquid feeding end in channel is connected with external cooling source, and the outlet end of the cooling duct is located at the two-end part of the stator winding
Set place.However, the first cooling duct of the program is by being formed between inner housing and outer housing, and its apocenosis passage is opened in shell
On body, oil outlet is on casing.Therefore, in order to reserve cooling duct, the inner housing and outer housing of CN201510819697A.X
Between only there are two position contact, contact area is small, and connection reliability is poor between inner housing and outer housing, the torsion that can be transmitted
Square is small.Simultaneously as only there are two support, all overhangings of complementary space between inner housing and outer housing.Stator core with it is interior
