Description

Technical Field

[0001] The utility model relates to the technical field of motor heat dissipation equipment, in particular to an automatic heat dissipation and temperature reduction component for a new energy vehicle motor. Background Art

[0002] A motor is a device that converts electrical energy into mechanical energy or mechanical energy into electrical energy. A motor has parts that can move relative to each other and is a device that operates by electromagnetic induction. The generator converts mechanical energy into electrical energy and the motor converts mechanical energy into electrical energy. In electric vehicles, the motor that provides driving force for the vehicle is called a new energy vehicle motor. New energy vehicle motors will generate a lot of heat under long-term operation. If the temperature around the motor is not controlled, the service life of the motor will be affected. The automatic heat dissipation and cooling components of the new energy vehicle motor are indispensable.

[0003] After searching, a new energy vehicle motor heat dissipation device in the Chinese utility model patent with patent number CN211046685U includes an outer cover, a motor housing, a base, a temperature control switch, a liquid pump, a support column and an exhaust fan. A motor is arranged inside the outer cover, and the motor housing of the motor is fixedly connected to the outer cover through a number of support columns. A number of heat dissipation ribs are arranged on the motor housing, and a condensation channel is arranged in the motor housing. The left port of the condensation channel is connected to the liquid inlet pipe, the liquid inlet pipe is connected to the liquid pump, and the right port of the condensation channel is connected to the liquid outlet pipe; the output shaft at the right end of the motor passes through the right end of the outer cover and extends to the outside, and an exhaust fan is arranged on the output shaft; a first filter is arranged in the middle of the left end face of the outer cover, a second filter is arranged on the right end face of the outer cover, and a temperature control switch is fixedly installed on the left inner wall of the outer cover; the utility model has a better control effect on the heat dissipation of the motor through controllable coolant cooling and exhaust heat dissipation, but The exhaust fan in the patent causes the airflow to be sucked in from the first filter at the left end of the outer cover, and then blown out from the second filter and the notch at the right end of the outer cover. The right end of the outer cover is the output end of the motor, which may be connected to a transmission device such as a gear, which will hinder the efficiency of the exhaust fan in dissipating heat to the outside. The heat is concentrated on the transmission device at one end of the output shaft, which will cause the transmission device, which is already running at high speed, to overheat and affect the service life of the transmission device. Although the coolant in the patent can dissipate heat, the liquid outlet pipe is connected to the coolant tank that comes with the car, which can only dissipate heat temporarily. The coolant in the coolant tank is limited and cannot be used for a long time. Moreover, the coolant will gradually heat up during the use of the car, and the cooling effect is low. It cannot be recycled, which is a waste of resources. Therefore, an automatic heat dissipation and cooling component for new energy vehicle motors is proposed, which can avoid the fan from dissipating heat to the motor output shaft transmission device and effectively circulate water cooling to evenly dissipate heat to the motor.

It solves the problem that the exhaust fan causes the airflow to be sucked in from the first filter at the left end of the outer cover and then blown out from the second filter and the notch at the right end of the outer cover. The right end of the outer cover is the output end of the motor and may be connected to transmission devices such as gears, which will hinder the efficiency of the exhaust fan in dissipating air to the outside to dissipate heat. In addition, the heat is concentrated on the transmission device at one end of the output shaft, which will cause the transmission device, which is already running at a high speed, to overheat and affect the service life of the transmission device. Although the coolant in the patent can dissipate heat, the liquid outlet pipe is connected to the coolant tank that comes with the car, which can only dissipate heat temporarily.

When the motor needs to be cooled, when the electronic temperature detector detects that the temperature is too high, the automobile central control automatically controls the cooling fan to start working, blows air to dissipate heat to the motor body, and the air is discharged from the outlet pipe to prevent heat from entering the automobile transmission device.

[0022] In the case implementation, the protection box 1 is provided with a motor body 401 inside, a fixing plate 402 is fixedly installed outside the motor body 401, a connecting plate 403 is provided on the right side of the motor body 401, a cooling liquid tank 404 is provided inside the fixing plate 402, a bottom plate 405 is fixedly installed at the bottom of the fixing plate 402, a liquid inlet pipe 408 is fixedly installed outside the fixing plate 402, a liquid outlet pipe 409 is fixedly installed outside the fixing plate 402, and the liquid outlet interface of the chiller 2 is connected to the cooling liquid tank 404 through a hose.

When the electronic thermometer 4011 detects a continuous increase, the car central control 3 controls the chiller 2 to start cooling, and transports cold water from the liquid inlet pipe 408 into the coolant tank 404 through a hose. The liquid outlet pipe 409 enters the chiller 2 through the hose for circulating cooling.

The air is discharged from the outlet pipe 4010 to prevent heat from entering the automobile transmission device. When the electronic thermometer 4011 detects that the temperature continues to rise, the chiller 2 starts to cool, and cold water is passed from the liquid inlet pipe 408 into the cooling liquid tank 404 through a hose, and then enters the chiller 2 from the liquid outlet pipe 409 through a hose for circulating cooling, and the coolant absorbs the heat emitted from the motor body 401 to effectively cool down. The cooling mechanism 4 can prevent the fan from dissipating heat to the motor output shaft transmission device, effectively circulate water to cool the motor evenly, and solve the problem that the exhaust fan causes the airflow to be sucked in from the first filter at the left end of the outer cover, and then blown out from the second filter and the notch at the right end of the outer cover. The right end of the outer cover is the output end of the motor and may be connected to transmission devices such as gears, which will hinder the efficiency of the exhaust fan to dissipate heat outward, and the heat is concentrated on the transmission device at one end of the output shaft, which will cause the transmission device, which is already running at a high speed, to overheat and affect the service life of the transmission device. Although the coolant heat dissipation in this patent can take away a lot of heat, the liquid outlet pipe is connected to the coolant tank that comes with the car, and can only dissipate heat temporarily.
