Abstract

The invention discloses a thermal management system. The thermal management system includes a refrigerant system and a cooling liquid system. The cooling liquid system includes a first cooling liquid system and a second cooling liquid system. The refrigerant system includes a compressor and a throttling element. The first coolant system includes a heater and a radiator, the second coolant system includes a cooler; the thermal management system includes a first heat exchanger and a second heat exchanger, and the first heat exchanger and the second The heat exchanger includes two channels; when the system is working, the first coolant system and the refrigerant system can exchange heat in the first heat exchanger, and the second coolant system and the refrigerant system can exchange heat in the second The heat exchanger performs heat exchange; the second coolant system also includes a third heat exchanger that can be used for heat exchange between the coolant and the electric heating device; the thermal management system also includes a parallel arrangement with the flow path where the third heat exchanger is located. The fluid flow path, so that the fluid of the second coolant system can selectively pass through the third heat exchanger.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a thermal management system for vehicles. Background technique [0002] Due to the characteristics of energy saving and environmental protection of electric vehicles, more and more vehicles currently use batteries as power or one of the powers, such as hybrid or pure electric vehicles. But in the case of using the battery as power, there is no waste heat from the engine to use at this time. If electric heating is used, it will lead to a large power consumption and affect the mileage of the electric vehicle. Therefore, the thermal management system in the vehicle should use the waste heat of the battery and other power electronic equipment as the heat source as much as possible, and use the heat pump to provide heat in the vehicle to improve the energy efficiency of the thermal management system and meet the cooling requirements of the vehicle power electronic equipment under dif...
