Electric vehicle heat management system with waste heat recycling function

Abstract

The invention discloses an electric vehicle heat management system with a waste heat recycling function. The system comprises a motor, a three-in-one control mechanism, an air conditioner loop systemand a battery. A heat dissipation port of the three-in-one control mechanism is connected with an inlet of the motor through a pipeline; and a heat dissipation opening of the motor is connected with an inlet of a heat storage device through the pipeline, a heat dissipation opening of the heat storage device is connected with an inlet of a temperature control valve through the pipeline, and an outlet of the temperature control valve is connected with a low-temperature radiator and an inlet of a four-way reversing valve through the pipelines. The electric vehicle heat management system with thewaste heat recycling function relates to the technical field of thermal management system. A motor cooling loop and a battery cooling loop are connected through the four-way reversing valve, waste heat of the motor can be used as a supplementary heat source of a battery and a heat pump air conditioning system, the function of recycling the waste heat of motor electric control is achieved, an energy utilization rate of the whole vehicle is increased, and an endurance mileage can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of thermal management systems, in particular to an electric vehicle thermal management system with waste heat recovery and utilization functions. Background technique [0002] Electric vehicle (BEV) refers to a vehicle powered by a vehicle-mounted power supply, driven by a motor to drive the wheels, and meets the requirements of road traffic and safety regulations. Due to its smaller impact on the environment than traditional vehicles, its prospects are widely optimistic, but the current technology It is not yet mature, and the working principle is battery-current-power regulator-motor-power transmission system-driving the car. The types of electric vehicles are divided into pure electric vehicles (BEV), hybrid electric vehicles (HEV) and fuel cell vehicles (FCEV) ), pure electric vehicles are driven by electric motors. Compared with fuel vehicles, the main difference lies in the four major components, drive...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a thermal management system for electric vehicles with the function of waste heat recovery and utilization, which solves the problem that heat is directly lost to the air by low-temperature radiators and fans, causing a certain amount of heat loss. Under the environment, both the battery and the air conditioning system need to use an independent electric heater to provide heat source, which consumes a lot of electric energy and greatly reduces the problem of the cruising range of electric vehicles.
