Document Type and Number:
WIPO Patent Application WO/2022/247602
Kind Code:
A1
Abstract:
A vehicle thermal management system and a vehicle. The vehicle thermal management system comprises a first cooling liquid circuit (L1), a second cooling liquid circuit (L2), a first flow path (F1) and a second flow path (F2), wherein a first water pump (10), an electric motor (20) and a radiator (30) are arranged on the first cooling liquid circuit (L1); a second water pump (40), a battery (60) and a first heat exchanger (50) are arranged on the second cooling liquid circuit (L2), the first heat exchanger (50) being further located on a refrigerant flow path of an air conditioning system of the vehicle; one end of the first flow path (F1) is connected to a cooling liquid outlet of the electric motor (20) and the other end is connected to a cooling liquid inlet of the first heat exchanger (50); and one end of the second flow path (F2) is connected to a cooling liquid outlet of the first heat exchanger (50) and the other end is connected to a cooling liquid inlet of the first water pump (10), such that the vehicle thermal management system has an electric motor waste heat recovery mode to provide heat to a refrigerant in the refrigerant flow path when the vehicle thermal management system is in the electric motor waste heat recovery mode, and in the waste heat recovery mode, a flow path of a cooling liquid is: the first water pump (10) to the electric motor (20) to a first switch valve (80) to the first heat exchanger (50) to a second switch valve (90) to the first water pump (10).
