Description

Technical Field

[0001] This utility model relates to the field of motor equipment technology, specifically to a heat dissipation structure for an electric vehicle motor. Background Technology

[0002] New energy electric vehicles are a type of electric vehicle. The motor of an electric vehicle generates a lot of heat during operation, which can cause the motor temperature to become too high and affect the motor's lifespan. Therefore, it is necessary to cool down the motor.

[0003] However, existing electric vehicle motors often rely on their own metal casing for heat dissipation, which results in poor heat dissipation, slow heat dissipation speed, and a lack of effective heat dissipation structures. Therefore, we propose a heat dissipation structure for electric vehicle motors. Utility Model Content

[0004] The purpose of this invention is to provide a heat dissipation structure for electric vehicle motors to address the aforementioned shortcomings in the technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat dissipation structure for an electric vehicle motor, including a motor mounting cover, wherein heat dissipation fins are fixedly arranged at equal intervals on the outer wall of the motor mounting cover, and a mounting cover is fixedly arranged on the outer wall of the heat dissipation fins. An air intake cover and an exhaust cover are respectively fixedly arranged on the outer walls of the motor mounting cover and the mounting cover at both ends. A first air intake pipe and a second air intake pipe are respectively connected to one side of the outer wall of the air intake cover through an opening.

The inner walls of the third fixing holes and the fourth fixing holes are equipped with matching bolts, so as to facilitate the installation of the first air intake shroud on one end of the universal air intake pipe.

[0008] Preferably, the outer wall of one side of the exhaust hood has equally spaced exhaust holes, which facilitate the discharge of gas that has entered the fixed hood.

[0009] Preferably, the first air intake cover is installed at the front of the new energy electric vehicle through a universal air intake pipe, which facilitates the entry of external air into the universal air intake pipe during vehicle operation.

[0032] Working principle of this utility model:

[0033] Refer to the instruction manual appendix Figure 1-6In use, the rotor, stator, and magnet are installed inside the motor mounting cover 1. The motor is then bolted to the electric vehicle via positioning holes 6 on the bottom positioning base plate 5 of the mounting base 4. The first air intake cover 11 is moved to the front of the new energy vehicle via the universal air intake pipe 10. During vehicle operation, external air enters the universal air intake pipe 10 through the first air intake cover 11. The air in the universal air intake pipe 10 then enters the air intake cover 7 through the first air intake pipe 9. The air in the air intake cover 7 passes through the mounting cover 3 and the outer wall of the heat dissipation fins 2, effectively and quickly cooling the motor mounting cover 1. The air in the mounting cover 3 is discharged through the exhaust port 23 on one side of the exhaust cover 8. When the new energy electric vehicle is driven at low speed for an extended period, the airflow speed entering the mounting cover 3 is insufficient. At this time, the air intake fan 22 draws external air into the air intake cover 7 through the second air intake cover 21 and the second air intake pipe 20, further increasing the external airflow into the mounting cover 3. By increasing the speed of the external air passing through the outer wall of the heat dissipation fins 2, the heat dissipation effect of this invention is further enhanced.
