Description

Technical Field

[0001] This utility model relates to the field of motor cooling technology, specifically a cooling device for drive motors. Background Technology

[0002] A drive motor is a motor that converts electrical energy into mechanical energy to drive a vehicle. In new energy vehicles, the drive motor is the core component of the electric vehicle drive system and the main actuator for vehicle movement. It is responsible for converting electrical energy into mechanical energy to drive the car. At the same time, it can also act as a generator to convert mechanical energy into electrical energy and store it in the power battery.

[0003] According to a patent application published on the internet (authorization announcement number: CN220754570U), "This utility model discloses a cooling device for an electric motor, belonging to the field of electric motor cooling technology. It includes an electric motor body with multiple equidistantly arranged heat dissipation fins connected through its bottom. When the electric motor body is fixedly mounted on a supporting cooling box, all the heat dissipation fins can penetrate through the top of the supporting cooling box and be inserted into the coolant. The heat dissipation fins facilitate heat conduction and cooling between the heat inside the electric motor body and the coolant. Simultaneously, a circulating airflow cooling fan assembly is installed on the outer periphery of the electric motor body. This assembly introduces cool airflow into the inner cavity of the electric motor body and then exhausts hot airflow from the electric motor body, forming a circulating airflow cooling system. The coolant cools the heat dissipation fins, achieving rapid cooling. This circulating airflow cooling system effectively cools the stator, rotor, and output shaft, improving the service life of the electric motor."

[0004] Based on the above, the applicant believes the following deficiencies exist:

[0005] The cooling device for this motor includes the motor body. A circulating airflow fan assembly introduces cool air into the inner cavity of the motor body and then exhausts the hot air out of the motor body, forming an airflow circulation cooling system. Coolant is used to cool the heat dissipation fins, achieving rapid cooling. The airflow circulation cooling system cools the stator, rotor, and output shaft, thereby improving the motor's service life. However, this device, which only uses a fan to dissipate heat from the motor, has low overall efficiency and cannot achieve efficient heat dissipation from the motor. Utility Model Content

[0006] The purpose of this invention is to provide a cooling device for a drive motor to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a cooling device for a drive motor, comprising a drive motor body, a front housing provided on the front end surface of the drive motor body, a rear housing provided on the rear end surface of the drive motor body, a primary cooling mechanism provided on the surfaces of the drive motor body and the front housing, the primary cooling mechanism comprising a front heat dissipation component and a rear heat dissipation component, and a water cooling mechanism provided on the surface of the rear housing.

[0008] The water-cooling mechanism includes mounting bases. Mounting bases are installed on the left and right sides inside the rear housing. A heat dissipation sleeve is fixedly connected to the inner side of each mounting base. A cooling pipe connector is installed on the top of each mounting base. A cooling pipe is fixedly connected to the top of the cooling pipe connector. A cooling pipe water pump is installed on the surface of the cooling pipe. A cooling water tank is fixedly connected to the center of the top of the rear housing. Circulating water pumps are fixedly connected to both ends of the cooling water tank. A water supply pipe is installed between the circulating water pumps and the cooling pipe connector. Cooling grooves are formed on the surface of the heat dissipation sleeve. During operation, when the drive motor body overheats, the water-cooling mechanism starts working. The circulating water pumps discharge cooling water into the cooling pipe connectors, and the cooling pipe water pumps drive the cooling water to move inside the cooling pipes. The cooling water then cools the drive motor body through the cooling grooves. This achieves the circulation of cooling water, thereby cooling the drive motor body. Used in conjunction with the primary cooling mechanism, it effectively ensures the cooling effect of the drive motor body, keeping it at a suitable operating temperature.

[0009] Preferably, the heat dissipation sleeve is disposed at the rear end of the surface of the drive motor body, and the cooling water tank is installed at the top end of the surface of the cooling pipe.

[0010] Preferably, the front heat dissipation component includes a mounting port, which is located on the left and right ends of the front housing surface. An exhaust fan is installed inside the mounting port. A mounting frame is fixedly connected to the outer end of the mounting port. A dustproof net is installed on the outer end of the mounting frame. A temperature sensor, model PT-100, is installed on the top left end inside the front housing.

[0011] Preferably, four sets of mounting ports are provided, and four sets of exhaust fans, mounting frames and dustproof nets are provided.

[0012] Preferably, the rear heat dissipation assembly includes a connecting shaft, which is installed at the center of the rear of the drive motor body. A cooling fan is fixedly connected to the surface of the connecting shaft. A rear heat dissipation frame is installed on the rear of the drive motor body, and a rear dust filter is fixedly connected to the back of the rear heat dissipation frame.

[0013] Preferably, an output shaft is fixedly connected to the center of the front of the drive motor body, a motor base is fixedly connected to the bottom of the drive motor body, a base is installed at the bottom of the motor base, and plug-in sockets are fixedly connected to the left and right ends of the motor base, with the front housing plugged into the plug-in sockets.

[0014] Compared with the prior art, the present invention provides a cooling device for a drive motor, which has the following advantages:

[0015] 1. This cooling device for the drive motor is equipped with a water-cooling mechanism. During operation, when the drive motor body overheats, the water-cooling mechanism will start working. A circulating water pump will discharge cooling water into the cooling pipe connector. The cooling water pump will then move the cooling water inside the cooling pipes, cooling the drive motor body through the cooling tank. This achieves the circulation of cooling water, thereby cooling the drive motor body. When used in conjunction with the primary cooling mechanism, it can effectively ensure the cooling effect of the drive motor body, ensuring that the drive motor body is always at a suitable operating temperature.

[0016] 2. The cooling device for the drive motor is equipped with a primary cooling mechanism. When the drive motor body is working, the temperature of the drive motor body is monitored by a temperature sensor. If the temperature is low, only the front heat dissipation component is activated to perform preliminary cooling of the drive motor body. The heat is discharged from the front casing by the exhaust fan to ensure a constant internal temperature. During operation, the output shaft will also drive the connecting shaft to rotate. The connecting shaft and the heat dissipation fan will dissipate some of the heat generated by the drive motor body during operation, thereby creating a suitable working temperature.

[0029] The water-cooling mechanism 9 includes a mounting base 91. Mounting bases 91 are installed on the left and right sides inside the rear housing 7. A heat dissipation sleeve 92 is fixedly connected to the inner side of the mounting base 91. A cooling pipe connector 93 is installed on the top of the mounting base 91. A cooling pipe 94 is fixedly connected to the top of the cooling pipe connector 93. A cooling pipe water pump 95 is installed on the surface of the cooling pipe 94. A cooling water tank 96 is fixedly connected to the center of the top of the rear housing 7. A circulating water pump 97 is fixedly connected to the left and right ends of the cooling water tank 96. A water supply pipe 98 is installed between the circulating water pump 97 and the cooling pipe connector 93. A cooling groove 99 is opened on the surface of the heat dissipation sleeve 92. When the drive motor body 1 overheats during operation, the water-cooling mechanism 9 will start to work. The circulating water pump 97 discharges cooling water into the cooling pipe connector 93. The cooling pipe water pump 95 drives the cooling water to move inside the cooling pipe 94. The cooling groove 99 cools the drive motor body 1. The cooling water is circulated to cool the drive motor body 1. When used in conjunction with the primary cooling mechanism 8, it can effectively ensure the cooling effect of the drive motor body 1 and keep the drive motor body 1 at a suitable operating temperature.

[0030] The heat sink 92 is located at the rear end of the surface of the drive motor body 1, and the cooling water tank 96 is installed at the top end of the surface of the cooling pipe 94.

[0031] Example 2

[0032] Please see Figure 1-5 Furthermore, based on Embodiment 1, the front heat dissipation component 81 includes a mounting port 811, which is opened at both ends of the surface of the front housing 6. An exhaust fan 812 is installed inside the mounting port 811. A mounting frame 813 is fixedly connected to the outer end of the mounting port 811. A dustproof net 814 is installed at the outer end of the mounting frame 813. A temperature sensor 815 is installed at the top left end inside the front housing 6. The temperature sensor 815 is model PT-100.

[0033] The mounting port 811 is provided with four sets, and the exhaust fan 812, mounting frame 813 and dustproof net 814 are provided with four sets;

If the temperature is low, only the front heat dissipation component 81 is activated to initially cool the drive motor body 1. The heat is discharged from the front housing 6 by the exhaust fan 812 to ensure a constant internal temperature. During operation, the output shaft 2 will also drive the connecting shaft 821 to rotate.

The circulating water pump 97 discharges cooling water into the cooling pipe connector 93, and the cooling pipe pump 95 drives the cooling water to move inside the cooling pipe 94, cooling the drive motor body 1 through the cooling tank 99. This achieves the circulation of cooling water, thereby cooling the drive motor body 1. Used in conjunction with the primary cooling mechanism 8, this effectively ensures the cooling effect of the drive motor body 1, keeping it at a suitable operating temperature.
