Description

Technical Field

[0001] This utility model relates to the field of electric vehicle sidecar motor technology, specifically to a liquid cooling heat dissipation device for electric vehicle sidecar motors. Background Technology

[0002] Side-mounted motors are motors mounted on the side of the wheel, and are widely used due to their advantages such as high motor speed and space saving. However, existing side-mounted motors generate energy losses during operation. This lost energy is converted into heat, causing the temperature of various motor components to rise, which is detrimental to the normal operation of the motor and greatly affects its lifespan and working efficiency. Therefore, a cooling device is needed to assist in dissipating heat from the outer surface of the side-mounted motor. However, existing cooling devices only rely on air cooling for physical cooling, thus reducing the practicality of the cooling device. Utility Model Content

[0024] The present invention will be further described in detail below with reference to embodiments: Example

[0025] like Figures 1-5 As shown, this utility model provides a liquid cooling heat dissipation device for a side-mounted motor of an electric vehicle, applied to the side-mounted motor body 1; a liquid cooling unit 2 disposed on the outer surface of the side-mounted motor body 1 for cooling; and a heat dissipation unit 3 disposed on the outer surface of the side-mounted motor body 1 for heat dissipation. The liquid cooling unit 2 includes a mounting assembly and a cooling assembly disposed on the outer surface of the mounting assembly. The heat dissipation unit 3 includes a heat conduction assembly disposed on the outer surface of the side-mounted motor body 1 and a heat dissipation assembly disposed on the outer surface of the heat conduction assembly. The mounting assembly includes a liquid storage ring 21, the outer surface of which is detachably connected to the outer surface of the side-mounted motor body 1. A groove 211 is formed on the outer surface of the liquid storage ring 21, and a liquid storage cavity is provided inside the liquid storage ring 21. A connecting copper pipe 22 is fixedly connected to the outer surface of the liquid storage ring 21. The cooling assembly includes... A heat-conducting plate 23 is fixedly connected to the inner wall of a groove 211 on one side. A mounting plate 24 is fixedly connected to the outer surface of the heat-conducting plate 23. A bearing seat 25 is rotatably connected to the inner wall of the mounting plate 24. A fan blade is provided on the outer surface of the bearing seat 25. When using the liquid cooling device for the electric vehicle side-mounted motor, the liquid storage ring 21 is first installed on the outer surface of the side-mounted motor body 1, and coolant is injected into the liquid storage ring 21. During the electric vehicle's operation, the wind force will drive the bearing seat 25 to rotate at high speed, thereby increasing the airflow speed on the outer surface of the heat-conducting plate 23. This allows the heat-conducting plate 23 to assist in cooling the coolant inside the liquid storage ring 21. The heat-conducting plate 23 is connected to the coolant in the heat dissipation unit 3 via a connecting copper pipe 22, thereby using the principle of heat exchange to assist in cooling the coolant inside the liquid storage ring 21. Example

[0026] like Figures 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the heat conduction assembly includes a liquid storage shell 31, the outer surface of which is detachably connected to the outer surface of the side-mounted motor body 1, the interior of which is connected to one end of a connecting copper pipe 22, a heat exchange plate 32 fixedly connected to the outer surface of which, one side of which extends into the interior of which, the heat dissipation assembly includes a heat dissipation fin 34, one side of which is fixedly connected to the outer surface of the heat exchange plate 32, a heat dissipation copper pipe 33 fixedly connected to the inner wall of which, a rotating shaft seat 36 rotatably connected to the outer surface of which, a mounting ring 37 fixedly connected to the outer surface of which, and a turbulence fin 35 fixedly connected to the outer surface of which, the turbulence fin 35... Multiple sets of cooling rings 37 are evenly distributed on the outer surface of the mounting ring 37. During the operation of the side-mounted motor body 1, heat is generated on the surface of its housing. The coolant inside the liquid storage housing 31 assists in dissipating heat from the outer surface of the housing through heat conduction. During the heat dissipation process, the temperature of the coolant will rise. The electric vehicle generates airflow during operation, which increases the airflow velocity on the outer surface of the heat dissipation copper pipe 33 and heat dissipation fins 34. This, in conjunction with the heat exchange plate 32, helps to cool the coolant inside the liquid storage housing 31. At the same time, during the operation of the electric vehicle, due to the action of the baffle fins 35, the rotating shaft seat 36 and the mounting ring 37 drive the baffle fins 35 to rotate, thereby disrupting the airflow direction and making the airflow more effective at dissipating heat from the outer surface of the heat dissipation copper pipe 33 and heat dissipation fins 34, thus improving the heat dissipation effect of the liquid cooling device.

[0027] The working principle of this liquid cooling heat dissipation device used for the side-mounted motor of electric vehicles will be explained in detail below.

[0028] like Figures 1-5As shown, when using the liquid cooling device for the side-mounted motor of an electric vehicle, the liquid storage ring 21 is first installed on the outer surface of the side-mounted motor body 1, and coolant is injected into the liquid storage ring 21. During the operation of the electric vehicle, the wind force will drive the axle seat 25 to rotate at high speed, thereby increasing the airflow velocity on the outer surface of the heat conduction plate 23. This allows the heat conduction plate 23 to assist in cooling the coolant inside the liquid storage ring 21. The copper pipe 22 is connected to the coolant in the heat dissipation unit 3, thus using the principle of heat exchange to assist in cooling the coolant inside the liquid storage ring 21. During the operation of the side-mounted motor body 1, heat is generated on the surface of its casing, which is then cooled by the liquid storage casing. The coolant inside the housing 31 assists in dissipating heat from the outer surface of the housing through heat conduction. During the heat dissipation process, the temperature of the coolant will rise. The electric vehicle generates airflow during operation, which increases the airflow velocity on the outer surface of the heat dissipation copper pipe 33 and heat dissipation fins 34. This, in conjunction with the heat exchange plate 32, helps to cool the coolant inside the liquid storage housing 31. At the same time, during the operation of the electric vehicle, due to the action of the baffle fins 35, the rotating shaft seat 36 and the mounting ring 37 drive the baffle fins 35 to rotate, thereby disrupting the airflow direction. This makes the airflow more effective at dissipating heat from the outer surface of the heat dissipation copper pipe 33 and heat dissipation fins 34, thus improving the heat dissipation effect of the liquid cooling device.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
