Abstract: This application provide a refrigerant thermal management module and a thermal management system. Components in the refrigerant thermal management module are centrally arranged, so that a pipeline connected between the components is shortened and a refrigerant flow resistance is reduced, improving working performance of a refrigerant loop. In addition, a platform-based design is implemented through modular design. In addition, a plate heat exchanger in the refrigerant loop is used to absorb heat from a coolant loop in a vehicle function module, to implement a function of cooling the vehicle function module; and a condenser in the refrigerant loop is used to release heat to the coolant loop of the vehicle function module, to implement a function of heating the vehicle function module. Regardless of whether the vehicle function module needs to be heated or cooled, refrigerant flows in the refrigerant thermal management module keep a same direction of circulation.

Abstract: This application provides a thermal management system. The thermal management system includes a refrigerant loop and a motor coolant loop. The refrigerant loop and the motor coolant loop jointly include a low pressure chiller. The low pressure chiller is configured to enable a refrigerant in the refrigerant loop to absorb heat from a motor coolant in the motor coolant loop, to heat a target temperature-controlled space and/or a target temperature-controlled device. Therefore, a temperature of the motor coolant may be relatively low on a basis that a required heating temperature can be achieved, so that a difference between the temperature of the motor coolant and an ambient temperature is relatively small. In this way, heat loss caused by dissipation of heat from a motor to a surrounding environment can be reduced, thereby improving utilization of the heat from the motor.
