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 third cooling liquid flow path, a first heat exchanger and a second heat exchanger. The first end of the first cooling liquid flow path, the first end of the second cooling liquid flow path and the first end of the third cooling liquid flow path are connected with one another, and the second end of the third cooling liquid flow path is selectively connected with the second end of the first cooling liquid flow path or the second end of the second cooling liquid flow path; a motor is arranged on the first cooling liquid flow path or the second cooling liquid flow path, a battery pack is arranged on the second cooling liquid flow path, a first water pump is arranged on the third cooling liquid flow path, and the first heat exchanger is arranged in the third cooling liquid flow path and an air conditioning system of a vehicle heat management system at the same time. The second heat exchanger is arranged in the cooling liquid loop and the air conditioning system at the same time, and a second water pump and a warm air core body are further arranged on the cooling liquid loop.

Description

technical field [0001] The present disclosure relates to the technical field of vehicle thermal management systems, in particular, to a vehicle thermal management system and a vehicle. Background technique [0002] In the vehicle thermal management system, it usually includes the air-conditioning thermal management system, the motor thermal management system, and the battery thermal management system. For the thermal management system of the air conditioner, when the ambient temperature is low, the heating capacity of the air conditioner is poor, and it is usually difficult to meet the heating demand of the passenger compartment; for the thermal management system of the motor, the motor will generate heat when driving the vehicle. In order to ensure the normal operation of the motor, it is necessary to dissipate heat and cool the motor; for the battery thermal management system, in order to ensure that the battery pack can work within its suitable temperature range, it is ne...

Problems solved by technology

For the thermal management system of the air conditioner, when the ambient temperature is low, the heating capacity of the air conditioner is poor, and it is usually difficult to meet the heating demand of the passenger compartment; for the thermal management system of the motor, the motor will generate heat when driving the vehicle. In order to ensure the normal operation of the motor, it is necessary to dissipate heat and cool the motor; for the battery thermal management system, in order to ensure that the battery pack can work within its suitable temperature range, it is necessary to cool the battery pack with too high temperature, and to low battery pack for heating

[0003] Since the existing air-conditioning thermal management system, motor thermal management system, and battery thermal management system operate independently of each other, on the one hand, the heat collection planning of the vehicle thermal management system will be unreasonable, resulting in energy waste, and on the other hand, it will lead to The number of pipelines, valves, joints and other components in the vehicle thermal management system increases, resulting in an increase in cost
