Title:
THERMAL MANAGEMENT SYSTEM FOR VEHICLE, AND THERMAL MANAGEMENT METHOD BASED ON THERMAL MANAGEMENT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/036957
Kind Code:
A1
Abstract:
Disclosed are a thermal management system and method for a vehicle. In the thermal management system, a refrigerant loop system comprises: a compressor (1), a refrigerant four-way reversing valve (2), a plate heat exchanger (3), a throttle valve (4), another plate heat exchanger (5), and a gas-liquid separator (6) so as to form a refrigerant loop; an electric motor liquid cooling loop system comprises an electric motor liquid cooling loop, flowing through an electric motor (11), of a circulating cooling liquid, and a pipeline in the electric motor liquid cooling loop is connected to a liquid cooling channel in the plate heat exchanger (3) so as to exchange heat with the refrigerant loop system through the plate heat exchanger (3); and an air conditioner liquid cooling loop system comprises an air conditioner liquid cooling loop, flowing through an air conditioner unit, of the circulating cooling liquid, and a pipeline in the air conditioner liquid cooling loop is connected to a liquid cooling channel in the another plate heat exchanger (5) so as to exchange heat with the refrigerant loop system through the another plate heat exchanger (5). The implementation of the thermal management system for a vehicle facilitates the saving of space in the front cabin of a vehicle and reducing the cost of the thermal management system.
