Abstract

The invention discloses an engine-motor integral cooling device for a hybrid electric vehicle and the hybrid electric vehicle. The engine-motor integral cooling device comprises an engine cooling system, a motor cooling system and a communication control system, wherein the engine cooling system comprises a first water pump, an engine, a thermostat, a first water path radiator and a first electromagnetic valve; the motor cooling system comprises a second water path radiator, a second water pump, a shunt valve, a motor controller, a motor and a second electromagnetic valve; the communication control system comprises a third electromagnetic valve, a fourth electromagnetic valve and a heat management controller; the opening of the third electromagnetic valve and the fourth electromagnetic valve and the closing of the first electromagnetic valve and the second electromagnetic valve are controlled through the heat management controller; the engine cooling system and the motor cooling system run in a series manner.

Description

technical field [0001] The invention relates to the technical field of electrical equipment for electrically driven vehicles, in particular to an engine-motor integrated cooling device for a hybrid vehicle and the hybrid vehicle. Background technique [0002] Compared with traditional pure internal combustion vehicles, hybrid vehicles have added components such as motors and motor controllers, and their structures are more complex. During the operation of the vehicle, the engine, engine controller, motor, and motor controller all need to be cooled, and the suitable operating temperature ranges of the three are different from each other. It is necessary to effectively cool these heating elements so that they can work within the appropriate operating temperature range . At the same time, the comprehensive utilization of energy should be considered as much as possible, so as to better realize the goal of energy saving and environmental protection of hybrid electric vehicles. ...
