Abstract
A vehicular heat management system includes a heat pump cycle capable of heating a heat-exchanging-object fluid by using exhaust heat of an in-vehicle device as a heat source that radiates heat during operation, and an exhaust-heat refrigerant circuit that releases the exhaust heat to outside air through an exhaust-heat refrigerant. The heat pump cycle includes a recovery heat exchange portion that performs heat exchange between a heated air heated by the exhaust heat and a cycle refrigerant circulating in the heat pump cycle. The exhaust-heat refrigerant circuit includes an exhaust-heat exchange portion that performs heat exchange between the heated air and the exhaust-heat refrigerant. The recovery heat exchange portion and the exhaust-heat exchange portion are integrally formed as a combined heat exchanger capable of transferring heat between the cycle refrigerant and the exhaust-heat refrigerant.
