[0021] The technical scheme of the utility model will be further specifically explained below by examples in combination with the drawings.

[0022] Embodiment:

[0023] As Figure 1 and 2 and 3 and 4 and 5 and 6 and 7, an oil-cooled self-cooling water pump structure, comprising a water pump, the water pump is composed of a water pump shell 1, a pump head 2, a rotor 3, a stator 4, a controller 5 and electronic components, the water pump shell 1 is an integral type machining formed metal structure, and a plurality of reinforcing ribs 6 are integrally machined and formed on the water pump shell 1.

[0024] The water pump shell 1 is respectively machined and formed with an oil inlet 7 and an oil outlet 8, and a water jacket 9 is arranged between the stator 4 and the rotor 3 in the water pump, and the stator 4 region and the controller 5 are in communication structure, and in working, the rotor 3 is immersed in water, and the stator 4 is immersed in oil.

[0025] The cooling channel 10 is arranged between the controller 5 and the stator 4 structure, and the cooling channel 10 is arranged at the bottom of the controller 5; the direction of the oil entering the controller 5 from the cooling channel 10 is opposite to the direction of gravity.

[0026] The heat dissipation piece is embedded and installed on the water pump shell 1, the heat dissipation piece comprises a heat conduction sheet 11 embedded on the water pump shell 1, and the heat conduction sheet 11 is a metal sheet with good heat conduction performance; one end of the heat conduction sheet 11 extends to one side surface of the pump head 2, and the other end of the heat conduction sheet 11 extends into the cavity of the stator 4 structure.

[0027] In working, the oil inlet 7 and the oil outlet 8 of the water pump shell 1 are connected with an external oil cooling circulation system, the oil enters from the oil inlet 7, passes through the stator 4 structure and the controller 5, and then flows out from the oil outlet 8, in working, the rotor 3 is immersed in water, and the stator 4 and the controller 5 are immersed in oil, the stator 4 and the controller 5 are cooled by the oil, and the heat dissipation efficiency is greatly improved.

[0028] The cooling channel 10 between the controller 5 and the stator 4 is used for oil to enter the controller 5 to cool, but because the opening direction of the cooling channel 10 is opposite to the oil entering direction and the gravity direction, the flowing speed of the oil in the controller 5 cavity is lower than that at the motor stator 4, so the impact on the electronic elements of the controller 5 can be reduced.
