Rotor and stator need to be cooled during working process.

[0003] At present, the heat dissipation mode of rotor and stator in electronic water pump is to immerse rotor in fluid, and fluid is used to dissipate heat of rotor. Meanwhile, water room is arranged outside rotor, and fluid is located inside water room, and stator is arranged outside water room. When installing stator and water room, in order to facilitate installation between stator and water room, certain gap must be provided between outer wall of stator and water room. Heat of stator is transmitted to water room through air in gap, and then water room transmits heat to fluid to dissipate heat.

[0004] However, the following problems exist in use process. Since heat of stator needs to be transmitted to water room through air in gap during heat dissipation, and heat conduction efficiency of air is low, air thermal resistance between stator and water room is large, which results in low heat dissipation efficiency of stator and inconvenient use.

Gap is provided between stator core and water room. Heat transfer mechanism is installed in gap between stator core and water room. Heat transfer mechanism has heat transfer function. When stator core is used, heat of stator core is transmitted to water room through heat transfer mechanism, and then heat is transmitted to fluid through water room to dissipate heat and cool. When stator core is used for heat dissipation, heat on stator core can be transmitted to water room through heat transfer mechanism, heat transfer efficiency is high, heat dissipation effect of stator core is improved, and the utility model is convenient to use and has high practicability.

[0007] Preferably, the heat transfer mechanism is a heat-conductive silicone grease, which is located at the gap between the stator core and the water-separation chamber, and is in contact with the outer sidewall of the water-separation chamber and the stator core.

[0008] Preferably, the part of the stator core in contact with the heat-conductive silicone grease is provided with an arc-shaped groove. Through the above arrangement, the contact area of the stator core and the heat-conductive silicone grease is increased, and the heat transfer effect is further improved, thereby improving the heat dissipation effect of the stator core.

[0009] Preferably, the outer sidewall of the water-separation chamber is provided with a boss. The heat-conductive silicone grease is uniformly filled in the gap between the water-separation chamber and the stator core, and the contact area of the water-separation chamber and the stator core with the heat-conductive silicone grease is increased by providing the boss on the water-separation chamber and the arc-shaped groove on the stator core, thereby improving the heat dissipation effect.
