The electronic water pump is generally composed of a stator assembly, a rotor assembly rotating around the stator shaft, a volute that decelerates and pressurizes the fluid, an end cover that provides electrical connection, a sealing ring for sealing the cavity, and a control board.

[0003] The water pump is provided with a rotor inside, and the rotor cooperates with the stator to make the water pump work. When the rotor of the water pump reaches a high temperature, the heat is transferred to the outside of the water pump, which will cause various adverse effects such as thermal expansion of the water pump. Therefore, a water pump rotor with a heat dissipation function is proposed. Summary of the invention

[0022] A water pump rotor with a heat dissipation function comprises a rotating shaft 1 and a rotor 4 connected thereto, wherein an excitation coil 3 is arranged around the rotor 4 to provide an excitation current, thereby generating a magnetic field to ensure that the water pump can operate normally, and an auxiliary heat dissipation hole 6 penetrating both ends of the rotor 4 is provided for heat dissipation at both ends, and at the same time, an interconnected channel 7 is provided between the auxiliary heat dissipation holes 6 so that each heat dissipation hole or channel can be connected to improve the heat dissipation efficiency. In order to further improve the heat dissipation efficiency, a strip-shaped heat dissipation main hole 5 connected to the auxiliary heat dissipation hole 6 through the channel 7 is provided on the outer wall of the rotor 4 for further heat dissipation outward;

[0023] In order to facilitate the heat dissipation at three locations, an opening 401 connected to the auxiliary heat dissipation hole 6 is opened on the inner wall of the rotor 4.

[0024] like Figure 1 As shown: the bearing 2 is installed on the shaft body of the rotating shaft 1, which can provide the force and support required by the rotor 4 and avoid generating excessive centrifugal force.

[0025] like Figure 1 As shown: the rotor 4 is provided with five petals.
