Electric automobile driving motor cooling system
Electric automobile driving motor cooling system
The invention discloses an electric automobile driving motor cooling system. The system comprises a motor heat dissipation loop, the motor heat dissipation loop comprises a motor radiator, a first teejoint, a second tee joint, a first water pump, a third tee joint, an electronic three-way valve, an electronic four-way valve and connecting pipelines. The motor radiator, the first tee joint, the second tee joint, the first water pump and the third tee joint are sequentially connected through the connecting pipelines, the rear portion of one pipe opening of the third tee joint is sequentially connected with a charger, a motor controller and a driving motor through pipelines, and the electronic four-way valve comprises a first valve port, a second valve port, a third valve port and a fourth valve port. The third valve port is connected with the liquid coolant outlet of the driving motor, the first valve port is connected with the electronic three-way valve, the electronic three-way valveis connected with the motor radiator, and the fourth valve port and the second valve port are connected with the inlet and the outlet of a fan heater loop respectively. The electric automobile drivingmotor cooling system can reduce the power consumption of a battery, prolong the endurance mileage and prolong the service life of the electronic fan, and is high in practicability.
