[0025] like Figures 5 to 7As shown, a plurality of ventilation slots 16 are formed around the outer ring of one side of the end cover 5 close to the cooling channel 4; the rotating shaft of the gear 14 passes through the ventilation slots 16; the ventilation slots 16 are correspondingly connected to the cooling channel 4; a filter screen 17 is fixedly connected to one end of the ventilation slots 16 close to the outer periphery of the end cover 5; When working, the fan blades 9 rotate, and the outside air is sucked into the cooling channel 4 through the ventilation slots 16 at one end to form wind. After the wind passes through the cooling channel 4, it is discharged from the ventilation slots 16 at the other end; through the filter net 17, the dust from the outside is effectively filtered, reducing the dust entering the cooling channel 4 and improving the cleanliness of the inside of the cooling channel 4.

[0026] like Figure 5 and Figure 7 As shown, the upper half of the end cover 5 has a plurality of ventilation slots 16, and one end close to the center of the end cover 5 is provided with a drainage hole 18; the two ends of the drainage hole 18 respectively penetrate the two sides of the bottom of the end cover 5; When the new energy vehicle is working in a rainy environment, a small amount of rainwater in the outside air will enter the ventilation groove 16 at the top of the end cover 5. After the rainwater enters the ventilation groove 16, the rainwater flows downward along the ventilation groove 16 and flows into the drainage hole 18.

[0027] like Figures 1 to 4 As shown, the inclination angles of the two blades 9 at both ends of the cooling channel 4 are opposite; During operation, by setting the angles of the fan blades 9 at both ends of the cooling channel 4 to be opposite, the fan blades 9 at both ends rotate synchronously, and the fan blades 9 at one end rotate to draw the outside air into the cooling channel 4, while the fan blades 9 at the other end rotate to extract the gas inside the cooling channel 4; thereby effectively improving the flow rate of the airflow inside the cooling channel 4.

[0028] like Figure 3 , Figure 4 and Figure 8 As shown, a plurality of gate-shaped tubes 19 are evenly arranged inside the cooling channel 4; the bottom surface of the gate-shaped tube 19 is fixedly connected to the inner circle of the cooling channel 4; the top surface of the gate-shaped tube 19 is fixedly connected to the top surface of the cooling channel 4; the top of the gate-shaped tube 19 is formed by alternately fixing a trapezoidal convex plate and a trapezoidal concave plate; A row of first guide plates 20 is evenly fixed to the bottom surface of the trapezoidal concave plate of the gate-shaped tube 19 and one side close to the air inlet of the cooling channel 4; each row of the first guide plates 20 is tilted; the tilt directions of the first guide plates 20 in two adjacent rows are opposite; During operation, after the outside air enters the interior of the cooling channel 4, the air is diverted into the gate tube 19. When the air passes through the bottom of the trapezoidal concave plate, the diameter of the gate tube 19 is reduced, so that the air velocity increases, and the air is guided by the inclined surface of the trapezoidal concave plate. At the same time, when the air passes through the gate tube 19, it is guided by multiple rows of No. 1 guide plates 20, so that the air flows in the gate tube 19 in an S shape, so that the air fully contacts the inner wall of the cooling channel 4, thereby improving the heat exchange between the air and the inner wall of the cooling channel 4; thereafter, when the air passes through the trapezoidal convex plate, the diameter of the gate tube 19 is increased, so that the air velocity decreases, and the air diffuses inside the trapezoidal convex plate in the gate tube 19, so that the heat in the air can be fully transferred to the housing 2 for heat dissipation, and finally, the heated air is discharged from the cooling channel 4; thereby, the air passing through the cooling channel 4 can fully exchange heat with the interior of the motor; At the same time, the plurality of gate-shaped tubes 19 are used to support the interior of the cooling channel 4 , thereby improving the overall strength of the inner shell 1 and the outer shell 2 .

[0030] Working principle: After the new energy vehicle is started, the heat generated by the operation of the motor is conducted through the inner shell 1, and the heat enters the cooling channel 4 between the inner shell 1 and the outer shell 2; at the same time, the motor shaft rotates, driving the rotating ring 11 to rotate in the middle of the transmission cavity 10, driving multiple support rods 12 to rotate, driving the gear ring 13 to rotate, driving multiple gears 14 to rotate, and rotating the fan blades 9 inside each cooling channel 4; The fan blades 9 rotate inside the circular groove 7 in the middle of the mounting plate 6, and suck the outside air into the cooling channel 4 through the ventilation groove 16 at one end to form wind. After the wind passes through the cooling channel 4, it is discharged from the ventilation groove 16 at the other end. When the outside air passes through the circular groove 7 of the mounting plate 6, the air enters the inside of the flow splitting shell 21, and the air is diverted and guided by the second guide plate 22, so that the air is dispersed from the center of the flow splitting shell 21 to the two sides of the flow splitting shell 21, so that the air can be fully dispersed into the multiple gate-shaped tubes 19 inside the cooling channel 4; When the air passes through the bottom of the trapezoidal concave plate, the diameter of the gate tube 19 is reduced, so that the air velocity increases, and the air is guided by the inclined surface of the trapezoidal concave plate. At the same time, when the air passes through the gate tube 19, it is guided by multiple rows of first guide plates 20, so that the air flows in the gate tube 19 in an S shape, so that the air fully contacts the inner wall of the cooling channel 4, and the heat exchange between the air and the inner wall of the cooling channel 4 is improved; after that, when the air passes through the trapezoidal convex plate, the diameter of the gate tube 19 is increased, so that the air velocity decreases, and the air diffuses inside the trapezoidal convex plate in the gate tube 19, so that the heat in the air can be fully transferred to the shell 2 for heat dissipation, and finally, the heated air is discharged from the cooling channel 4; Thereby, the heat generated by the motor is effectively discharged, and the heat dissipation efficiency and heat dissipation effect of the motor are improved; thereby, the safety of the motor operation is ensured, and the driving safety of new energy vehicles is improved.
