[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figure 1 The utility model provides a technical solution: a motor water cooling jacket, comprising a water cooling jacket body 1, a water inlet 2, a water outlet 3 and a water channel assembly 4; the water channel assembly 4 is arranged on the outer surface of the water cooling jacket body 1; the water inlet 2 and the water outlet 3 are respectively arranged at the upper and lower ends of the water cooling jacket body 1, and the water inlet 2 and the water outlet 3 are both connected to the water channel assembly 4.

[0019] The water cooling jacket body 1 is a cylindrical structure for accommodating the motor.

[0020] The water channel assembly 4 includes a U-shaped water channel 1 41, multiple annular water channels 42 and a U-shaped water channel 2 43; the U-shaped water channel 1 41 is located at the upper end of the water cooling jacket body 1, and the U-shaped water channel 2 43 is located at the lower end of the water cooling jacket body 1; the multiple annular water channels 42 are gap-arranged between the U-shaped water channel 1 41 and the U-shaped water channel 2 43, and the upper and lower ends of the annular water channel 42 are respectively connected to the U-shaped water channel 1 41 and the U-shaped water channel 2 43.

[0021] The water inlet 2 is set at the upper end of the U-shaped water channel 41, so that water flows into the U-shaped water channel 41 after entering through the water inlet 2.

[0022] The water outlet 3 is provided at the lower end of the second U-shaped water channel 43 , so that water flows through the second U-shaped water channel 43 and is discharged to the water outlet 3 .

[0023] Furthermore, the U-shaped water channel 1 41 , the plurality of annular water channels 42 and the U-shaped water channel 2 43 are all inwardly concave groove structures.

[0024] Furthermore, the U-shaped water channel 1 41 includes a U-shaped bend 1 411 and a U-shaped bend 2 412. The U-shaped bend 1 411 has a gradually inclined structure from the outside to the inside, that is, the outer bend of the U-shaped bend 1 411 is higher than the inner bend of the U-shaped bend 1 411, so that water flows from the upper end of the U-shaped water channel 1 41 through the U-shaped bend 1 411 to the lower end of the U-shaped water channel 1 41. The inclined structure of the U-shaped bend 1 411 can accelerate the flow of water and increase the cooling efficiency.

[0025] Furthermore, the end of the U-shaped water channel 1 41 and the top of the annular water channel 42 are connected to form a U-shaped bend 3 413 between the U-shaped water channel 1 41 and the annular water channel 42 .

[0026] Furthermore, the U-shaped bend 413 is a gradually inclined structure from the outside to the inside, that is, the outer bend of the U-shaped bend 413 is higher than the inner bend of the U-shaped bend 413, so that water flows from the end of the U-shaped water channel 1 41 through the U-shaped bend 413 to the annular water channel 42. The inclined structure of the U-shaped bend 413 can accelerate the flow of water and increase the cooling efficiency.

[0027] Furthermore, the annular water channel 42 includes an arcuate water channel 421 and an inclined water channel 422. The distal end of the U-shaped water channel 1 41 is connected to the inclined water channel 422, and the gap between the inclined water channel 422 and the arcuate water channel 421 is connected end to end. Water flows through the U-shaped water channel 1 41 and then into the inclined water channel 422, then into the arcuate water channel 421 and then into the inclined water channel 422. The provision of the inclined water channel 422 accelerates water flow and improves cooling efficiency.

[0028] Furthermore, the U-shaped water channel 2 43 includes a U-shaped bend 431, and the U-shaped bend 431 has a gradually inclined structure from the outside to the inside, that is, the outer bend of the U-shaped bend 431 is higher than the inner bend of the U-shaped bend 431, so that water flows from the upper end of the U-shaped water channel 2 43 through the U-shaped bend 431 to the lower end of the U-shaped water channel 2 43. The inclined structure of the U-shaped bend 431 can accelerate the flow of water and increase the cooling efficiency.

[0029] During use, water flows through the water inlet 2 into the U-shaped water channel 1 41 , the multiple annular water channels 42 and the U-shaped water channel 2 43 , and finally flows out through the water outlet 3 .
