Problems solved by technology
[0002] At present, the heat generated by water-cooled motors and motor controllers is mainly delivered to the electric radiator through the water pump to dissipate heat. After the pure electric vehicle is started, the electric fan continues to work. The life of the fan motor is short and the heat cannot be used.

Embodiment Construction
[0014] Such as figure 1 As shown, the present invention is a thermal management device for an electric vehicle, which includes a water-cooled motor 1, a motor controller 2, a water pump 3, a normally open solenoid valve 4, a flow regulating valve 5, a first radiator 6, and a second radiator 7 and expansion tank 8.
[0015] The heat dissipation water jacket of the motor controller 2 equipped with a water temperature sensor 21 is connected with the heat dissipation water jacket of the water-cooled motor 1 through a pipeline. The water temperature sensor 21 can detect the temperature of the water outlet of the motor controller 2 water jacket and send the signal to the motor control through the wire Device 2.
[0016] The cooling water jacket of the water-cooled motor 1 is connected with the normally open solenoid valve 4 , the first radiator 6 and the water pump 3 through a pipeline. The motor controller 2 is connected with the normally open electromagnetic valve 4 by electric ...

The invention discloses a heat management device of an electric car. A motor controller heat radiating water sleeve provided with a water temperature sensor is connected with a heat radiating water sleeve of a water-cooled type motor through a pipeline; one path of the heat radiating water sleeve of the water-cooled type motor is connected with a normally opened electromagnetic valve, a first heat radiator and a water pump through a pipeline, and the other path is connected with a flow adjusting valve, a second heat radiator and a water pump through a pipeline; a water inlet pipeline of the water pump is also connected with an expanding water tank; the expanding water tank is also connected with an exhaust opening of the heat radiating water sleeve of the water-cooled type motor through an exhaust pipeline; and a motor controller is connected with the normally opened electromagnetic valve, the flow adjusting valve, the water pump, the first heat radiator and a fan motor of the second heat radiator by a wire. Because the first heat radiator can defrost the front windscreen glass of a car and heat a car chamber, the service life of the fan motor of the second heat radiator is prolonged; and meanwhile, the parallel connection type structure improves the reliability of the heat management device of the pure electric car and effectively protects the motor and the controller. The invention also discloses a use method of the heat management device of the electric car.
Description
technical field [0001] The invention belongs to the technical field of thermal management of pure electric vehicles, and in particular relates to a thermal management device for electric vehicles and a use method thereof, in particular to the effective utilization of heat generated by the operation of a water-cooled motor and a controller thereof. Background technique [0002] At present, water-cooled motors and motor controllers generate heat when they work, mainly by pumping water to the electric radiator for heat dissipation. After the pure electric vehicle is started, the electric fan keeps working, and the life of the fan motor is short and the heat cannot be used. Contents of the invention [0003] An object of the present invention is to provide a heat management device for an electric vehicle with long service life of the fan motor and full use of heat. [0004] Another object of the present invention is to provide a method for using a heat management device for an...
