[0023] See also Figure 1-4 The utility model provides a technical solution: a high-efficiency heat dissipation structure of a micro motor, including a motor body 1, a drive shaft 2, a circulating water tank 3, a water inlet 4, a flange 5, a sealing ring 6, a water outlet 7, a heat sink 8, a fixing plate 9, a rear cover 10, a pumping box 11, a water storage box 12, a water inlet 13, a roller 14, a temperature sensor 15, a fan box 16, a heat dissipation port 17 and a dust cover 18, such as Figure 1 and Figure 3As shown, a driving shaft 2 is installed at the left end of the motor body 1, and the driving shaft 2 is convenient for connecting and installing the motor body 1. A supporting seat is installed at the lower end of the motor body 1, and the supporting seat supports and stabilizes the motor body 1. A circulating water tank 3 is reserved inside the motor body 1, and a water inlet 4 is installed at the upper end of the circulating water tank 3, and a water outlet 7 is installed at the lower end of the circulating water tank 3. When it is convenient to connect to an external water source, flanges 5 are installed at the openings of the water inlet 4 and the water outlet 7, and a sealing ring 6 is fixedly installed on the inner side of the flange 5. The external water pipe is connected to the water inlet 4 and the water outlet 7. Positioning holes are opened on the surface of the flange 5. The screws are aligned with the positioning holes on the surface of the flange 5, and the screws are tightened to fix the water inlet 4, the water outlet 7 and the water pipe. The sealing ring 6 increases the sealing of the water inlet 4, the water outlet 7 and the water pipe to prevent water leakage. When it is inconvenient to connect to an external water source, a water storage box 12 can be connected through a water pipe. The water storage box 12 stores coolant.

[0024] After the water inlet 4 and the water outlet 7 are connected to an external water source, the water pump is turned on, and the water pump delivers cold water to the circulating water tank 3 through the water inlet 4, and then flows back to the external water source through the water outlet 7, thereby forming a water circulation structure. The cold water circulates in the circulating water tank 3 in the motor body 1, which can dissipate heat for the motor body 1 and prevent the motor body 1 from being damaged by high temperature. When it is inconvenient to connect to an external water source, the water inlet 4 and the water outlet 7 are connected to an external water pump through a water pipe, and the water pump is connected to the water storage box 12 through the water pipe, so that the coolant in the water storage box 12 can circulate in the circulating water tank 3, thereby improving the heat dissipation effect of the motor body 1;
