Thermal management system for automobile and thermal management method based on the same

Abstract

Embodiments of the present application provide a thermal management system and method for an automobile. In the system, a refrigerant loop system includes: a compressor, a refrigerant four-way reversing valve, a plate heat exchanger, a throttle valve, another The plate heat exchanger and the gas-liquid separator form a refrigerant loop; the motor liquid cooling loop system includes a motor liquid cooling loop that circulates coolant through the motor, and the pipes in the motor liquid cooling loop are connected to a The liquid cooling channel in the plate heat exchanger exchanges heat with the refrigerant loop system through the plate heat exchanger; the air conditioning liquid cooling loop system includes the air conditioning liquid cooling loop that circulates the cooling liquid through the air conditioning box. The pipes in the liquid cooling loop are connected to the liquid cooling channel in another plate heat exchanger, and heat exchange with the refrigerant loop system is carried out through the plate heat exchanger. Implementing the present application is beneficial to saving the space of the front cabin of the vehicle and saving the cost of the thermal management system.

Description

Technical field [0001] This application involves automotive thermal management technology, especially the thermal management system for automobiles and the thermal management methods based on the system. Background technique [0002] Electric vehicles usually use motor driving, which brings challenges to the heat production of the car's air -conditioning system. Most of the electric vehicle air conditioners depend on electric heating equipment to make heat, but this method of heating directly uses electric heating is low, and the power consumption is large. For electric vehicles, it is not enough for electric vehicles. Due to the relatively high heating efficiency of heat pump technology, more and more auto manufacturers tend to use heat pump technology to improve the electrical economy of electric vehicle air -conditioning systems. [0003] At present, the condenser used when the heat pump and air conditioning system is directly changed during heat exchanging heat changes is mai...
