Document Type and Number:
WIPO Patent Application WO/2024/065154
Kind Code:
A1
Abstract:
Disclosed in the present invention are a thermal management system of a vehicle, and a vehicle. The thermal management system comprises a refrigerant circulation system and a cooling-liquid circulation system. The refrigerant circulation system comprises a compressor, a first heat exchanger, a first expansion valve, a second heat exchanger, a third heat exchanger, a second expansion valve and a first fluid line switching component. The first heat exchanger has a refrigerant channel and an electric drive cooling-liquid channel, which are independent and capable of heat transfer; the second heat exchanger has a refrigerant channel and a passenger compartment cooling-liquid channel, which are independent and capable of heat transfer; and the third heat exchanger has a refrigerant channel and a battery cooling-liquid channel, which are independent and capable of heat transfer. The cooling-liquid circulation system comprises a passenger compartment cooling-liquid circulation system and an engine room cooling-liquid circulation system. The passenger compartment cooling-liquid circulation system comprises a first water pump and a cold-hot core. The engine room cooling-liquid circulation system comprises an electric drive circulation circuit, a battery circulation circuit and a second fluid line switching component. The thermal management system is applicable to a refrigerant needing a secondary circuit, and the system has a small number of parts.
