Further: one side of the water cooling pipeline is provided with a water inlet and a water outlet which are respectively communicated with one group of radiating fins; the other side of the water cooling pipeline is provided with a water inlet and a water outlet which are the same, and the water inlet and the water outlet are also respectively communicated with the radiating fins, so that the radiating fins realize the water inlet and water discharge functions.

Further: and an expansion part for increasing the heat exchange area is arranged on the outer side of the radiating fin.

Further: and a cooling part communicated with the cooling flow channel is arranged in the expansion part.

The above technical scheme is adopted in the utility model, think about ingeniously, because both sides water inlet distributes differently, rivers in two sets of fins are to also different, there may be partial high temperature and the normal phenomenon of partial temperature in the actual work, if rivers in the fin are unidirectional, can lead to taking thermal rivers to the rear end when the front end component temperature is too high, the temperature that leads to the rear end component improves, there is the limitation to the heat dissipation, and this kind of condition then can not appear in two rivers of flow direction opposite, can make the radiating effect better, the heat dissipation is more even.

When water enters a cooling flow channel in the water cooling pipeline, the stator can be cooled, and after the water enters the stator from the cooling flow channel, due to the arrangement of the spiral radiating fins, the cooling water advances along the axial direction in the cooling flow channel by a spiral circle, so that the effect of the water cooling mechanism is more obvious, and a complete heat dissipation circulation is formed.

Common water-cooling mechanism possess single water inlet, single delivery port, and the flow direction of water is the folk prescription to the circulation, and water when flowing the position that is close the delivery port, the temperature is too high, leads to this regional part to reach the cooling effect of ideal, and this water-cooling mechanism designs into both ends and intakes, and the structure of both ends drainage compares common water-cooling mechanism, and the cooling effect of this water-cooling mechanism is better.
