[0002] Motors, as devices that convert electrical energy into mechanical energy, play a vital role in modern industrial and technological applications. However, it cannot be ignored that motors generate a lot of heat during operation. If this heat cannot be dissipated effectively and in a timely manner, the temperature of the motor will rise sharply. Excessive temperature will not only lead to a significant decline in motor performance, making it difficult to maintain a stable and efficient working state, but more seriously, it may also damage the internal structure of the motor, shorten its service life, and even directly cause damage to the motor.

[0003] At present, motors usually rely on natural heat dissipation of the casing or use air cooling, but the heat dissipation effect is not good.

DETAILED DESCRIPTION

[0026] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0027] Embodiment 1:

[0028] A long-lasting water-cooled motor, such as Figures 1 to 7 As shown, it includes a housing 1, a front cover 2, a rear cover 3, a rotating shaft 4, a stator 5 and a rotor 6. The front cover 2 and the rear cover 3 are respectively installed at two ends of the housing 1, and the stator 5 and the rotor 6 are both arranged in the housing 1.

[0029] The rotating shaft 4 is arranged in the housing 1 and connected to the rotor 6. A bearing 24 is arranged between the front end cover 2 and the rotating shaft 4. The front end cover 2 is provided with an installation chamber 25 for installing the bearing 24. The stability of the bearing 24 is ensured by the installation chamber 25.

[0030] The outer wall of the housing 1 is provided with a plurality of heat dissipation strip grooves 26 to increase the heat dissipation area and improve the heat dissipation effect.

[0031] The front end cover 2 is provided with a liquid inlet 7 and a water cooling channel 1 8, the liquid inlet 7 is connected to the water cooling channel 1 8, the outer shell 1 is provided with a water cooling channel 2 9, the rear end cover 3 is provided with a liquid outlet 10 and a water cooling channel 3 11, the liquid outlet 10 is connected to the water cooling channel 3 11, and the water cooling channel 1 8 and the water cooling channel 3 11 are both connected to a plurality of water cooling channels 2 9.

[0032] It should be noted that the coolant enters the water cooling channel 1 8 from the liquid inlet 7, and then flows through the water cooling channel 2 9 and the water cooling channel 3 11 in sequence, and finally flows out from the liquid outlet 10. When the coolant flows through the water cooling channel 1 8, the water cooling channel 2 9 and the water cooling channel 3 11, the heat generated at different positions inside the motor is taken away, thereby achieving long-term heat dissipation of the motor. Since the water cooling channel 1 8, the water cooling channel 2 9 and the water cooling channel 3 11 correspond to different heat source positions inside the motor respectively, the contact area between the coolant and the heat source inside the motor can be effectively increased, thereby improving the heat dissipation effect.

[0033] Furthermore, the water-cooling channel 1 8 and the water-cooling channel 3 11 are both annular, and there are several water-cooling channels 2 9. The several water-cooling channels 2 9 are evenly distributed along the circumference of the outer shell 1, and the two ends of the several water-cooling channels 2 9 are respectively connected to the water-cooling channel 1 8 and the water-cooling channel 3 11. It should be noted that the water-cooling channel 1 8 and the water-cooling channel 3 11 are both annular and there are several water-cooling channels 2 9, which can effectively increase the contact area between the coolant and the internal heat source of the motor, more effectively absorb the heat generated inside the motor, thereby significantly improving the heat dissipation effect, and the annular shape of the water-cooling channel 1 8 and the water-cooling channel 3 11 helps to achieve continuous flow of the coolant, ensure that the heat is taken away in time, and avoid heat accumulation inside the motor.

[0034] Furthermore, several water-cooling channels 29 are all trapezoidal in shape, thereby effectively increasing the area of ​​water-cooling channel 29, making the contact area between the coolant and water-cooling channel 29 larger, and transferring heat more effectively, thereby improving the heat dissipation effect. The trapezoidal water-cooling channel 29 can make the distribution of the coolant more uniform, thereby improving the heat dissipation efficiency. Moreover, the water-cooling channels 29 are all trapezoidal in shape, and the overall structure is more stable.

[0035] A positioning convex ring 12 is arranged on the end face of the front end cover 2. The front end cover 2 and the positioning convex ring 12 are arranged integrally. The positioning convex ring 12 is inserted into the outer shell 1, and the outer side wall of the positioning convex ring 12 is in contact with the inner side wall of the outer shell 1, and the inner end face of the front end cover 2 is in contact with the end face of the outer shell 1, thereby effectively ensuring the relative stability of the front end cover 2 and the outer shell 1.

[0036] An annular groove 14 is provided on the outer wall of the positioning convex ring 12, and a sealing ring 15 is arranged in the annular groove 14. An annular groove 3 18 is provided on the inner end surface of the front end cover 2, and a sealing ring 3 19 is arranged in the annular groove 3 18. The sealing ring 15 and the sealing ring 3 19 cooperate to seal the water cooling channel 8 to prevent the coolant in the water cooling channel 8 from leaking outward from between the shell 1 and the front end cover 2 or leaking inward into the motor.

[0037] A positioning convex ring 13 is provided on the end face of the rear end cover 3. The positioning convex ring 13 is inserted into the outer shell 1, and the outer wall of the positioning convex ring 13 is in contact with the inner wall of the outer shell 1. The inner end face of the rear end cover 3 is in contact with the end face of the outer shell 1, thereby effectively ensuring the relative stability of the rear end cover 3 and the outer shell 1.

[0038] An annular groove 2 16 is provided on the outer wall of the positioning convex ring 2 13, and a sealing ring 2 17 is arranged in the annular groove 2 16. An annular groove 4 20 is provided on the inner end surface of the rear end cover 3, and a sealing ring 4 21 is arranged in the annular groove 4 20. The sealing ring 2 17 cooperates with the sealing ring 4 21 to seal the water cooling channel 3 11 to prevent the coolant in the water cooling channel 3 11 from leaking outward from between the outer shell 1 and the rear end cover 3 or leaking inward into the motor.

[0039] A plurality of reinforcing blocks 22 are arranged in the water cooling channel 8, and the plurality of reinforcing blocks 22 are evenly distributed along the circumference of the water cooling channel 8, so as to ensure the structural strength and improve the structural stability. In addition, the plurality of reinforcing blocks 22 can slow down the flow rate of the coolant in the water cooling channel 8, so that the contact time between the coolant and the internal heat source of the motor is longer, and the heat dissipation effect is better.

[0040] A plurality of reinforcing blocks 3 23 are arranged in the water cooling channel 3 11, and the plurality of reinforcing blocks 3 23 are evenly distributed along the circumference of the water cooling channel 3 11, so as to ensure the structural strength and improve the structural stability. In addition, the plurality of reinforcing blocks 3 23 can slow down the flow rate of the coolant in the water cooling channel 2 9, so that the contact time between the coolant and the internal heat source of the motor is longer, and the heat dissipation effect is better.

[0041] Embodiment 2:

[0042] The difference between the second embodiment and the first embodiment is that Figure 8 As shown, the inner side walls of several water-cooling channels 29 are provided with several strip protrusions 27, and the several strip protrusions 27 can effectively improve the structural strength of the water-cooling channels 29 and the outer shell 1. By providing several strip protrusions 27 in the water-cooling channels 29, the contact area with the coolant can be increased, thereby improving the heat dissipation effect. Moreover, the strip protrusions 27 change the flow state of the coolant in the water-cooling channels 29, and the heat dissipation efficiency is higher.
