US Patent 11390135 Thermal management system for vehicle

A thermal management system for a vehicle is provided. The system includes an interior air conditioning apparatus and a chiller that exchanges heat between first refrigerant and second refrigerant. A first line guides the first refrigerant to be circulated sequentially through a chiller, a high-voltage battery cooling core and a heating, ventilating and air conditioning (HVAC) core. A second line guides the second refrigerant to be circulated sequentially through a compressor, a condenser and the chiller. A controller operates the blower, a first pump and the compressor based on an exterior temperature of the vehicle and whether interior air conditioning is necessary, when cooling of the high-voltage battery is necessary.
