Abstract: An intercooler includes a heat exchanger that has a first heat exchange portion through which a first heat exchange medium flows and a second heat exchange portion through which a second heat exchange medium flows. The first heat exchange medium flowing through the first heat exchange portion cools the supercharged intake air by exchanging heat with the supercharged intake air. The second heat exchange medium flowing through the second heat exchange portion cools the supercharged intake air by exchanging heat with the supercharged intake air. The heat exchanger includes an inner fin configured to enhance the heat exchange between the supercharged intake air and the first heat exchange medium. The heat exchanger includes a boiling suppression portion configured to suppress a boiling of the first heat exchange medium flowing in an upstream part, in a flow direction of the supercharged intake air, of the first heat exchange portion.

Abstract: An intercooler includes a heating portion in which flow path tubes and fins are stacked with each other. A second cooling medium flow path of the flow path tubes is located upstream of a first cooling medium flow path of the flow path tubes with respect to a flow direction of supercharged intake air. The second cooling medium flow path includes a second U-turn portion in which the second cooling medium makes a U-turn. In the second cooling medium flow path, a downstream flow path located downstream of the second U-turn portion is located upstream, in the flow direction of the supercharged intake air, of an upstream flow path located upstream of the second U-turn portion. The fins include a heat exchange limiting portion at least in a part adjacent to a most upstream part, in the flow direction of the supercharged intake air, of the downstream flow path.
