Vehicle thermal management system and vehicle

Abstract

The invention relates to a vehicle thermal management system and a vehicle. The system comprises a cooling liquid loop, a first cooling liquid flow path, a second cooling liquid flow path, a first three-way valve, a first heat exchanger and a second heat exchanger. A port A of the first three-way valve is connected with the first end of the first cooling liquid flow path, a port B of the first three-way valve is connected with the first end of the second cooling liquid flow path, and a port C of the first three-way valve is connected with the second end of the first cooling liquid flow path and the second end of the second cooling liquid flow path. A first water pump and an engine are arranged on the first cooling liquid flow path, the first heat exchanger is arranged on the second cooling liquid flow path and the cooling liquid loop at the same time, the second heat exchanger is arranged in the cooling liquid loop and an air conditioning system of a vehicle heat management system at the same time, and a warm air core and a second water pump are further arranged on the cooling liquid loop. In this way, heat exchange can be conducted between the engine and the warm air core body, heat exchange can be conducted between the air conditioning system and the warm air core body, and vehicle heat collection planning is reasonable.

Problems solved by technology

[0002] For the vehicle thermal management system of a hybrid vehicle, when the hybrid vehicle is driven by the engine, the engine will generate heat. In order to ensure the normal operation of the engine, it is necessary to dissipate heat and cool the engine. demand, the air conditioning system needs to be turned on to heat the passenger compartment. On the one hand, when the ambient temperature is low, the heat absorbed by the refrigerant is limited, and the heating capacity of the air conditioning system is poor. On the other hand, heating the passenger compartment through the air conditioning system will It leads to the loss of electric energy. Since hybrid vehicles can also convert the electric energy of the battery pack into mechanical energy to drive the vehicle in some implementation scenarios, the loss of electric energy is not conducive to improving the endurance of the battery pack.

In other words, the heat collection planning of the existing vehicle thermal management system is unreasonable, resulting in waste of energy
