US Patent 11472255 Chiller/warmer combination for an electric vehicle

A chiller/heater combination system for electric vehicles. The system includes a heat exchanger for 3 fluids. A first fluid is a high-temperature heat exchange fluid that cools components that generate heat, a second fluid is air conditioning refrigerant, and a third fluid is low-temperature heat exchange fluid used to heat or cool the motive unit. The heat exchanger may be a stacked plate design for three fluids. The low-temperature heat exchange fluid is cooled or heated in the three-fluid heat exchanger.
