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.

Abstract: A heat exchanger includes a duct, a stacked core, and a coupling plate. The duct includes a first plate that is disposed to face at least one of end faces of the stacked core in a core width direction, and a second plate that is disposed to face at least one of the end faces of the stacked core in a tube stacking direction. The second plate includes a second-plate end plate portion disposed to face the end face of the stacked core in the core width direction and brazed to a wall surface of the first plate, a second-plate center plate portion that is disposed to face the end face of the stacked core in the tube stacking direction, and a flange portion that extends in the tube stacking direction and is brazed to a bottom wall surface of a groove portion of the coupling plate.

Abstract: Provided is an aluminum alloy clad material including an aluminum alloy core material, an intermediate layer material that is clad on one surface of the core material, and a first brazing filler metal that is clad on a surface of the intermediate layer material, the surface not being on the core material side, wherein the core material, the intermediate layer material, and the first brazing filler metal each include an aluminum alloy having a predetermined composition, the existence density of Al—Mn based intermetallic compounds having a circle-equivalent diameter between 0.1 and 1.0 μm inclusive in the intermediate layer material before brazing heating is at least 1.0×105 pieces/mm2, and the existence density of Al—Mn based intermetallic compounds having a circle-equivalent diameter between 0.1 and 1.0 μm inclusive in the intermediate layer material after brazing heating is at least 1.0×104 pieces/mm2. Further provided is a method for producing the aluminum alloy clad material.

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 that cools intake air supercharged into an engine by a supercharger by exchanging heat with a cooling medium includes a heat exchange portion in which heat is exchanged between the cooling medium flowing inside a channel tube and the supercharged intake air flowing outside the channel tube. The cooling medium includes a first cooling medium and a second cooling medium hotter than the first cooling medium. The channel tube includes a first cooling medium channel where the first cooling medium flows and a second cooling medium channel where the second cooling medium flows. The channel tube includes a first U-turn portion forcing a flow of the first cooling medium flowing the first cooling medium channel to make a U-turn, and a second U-turn portion forcing a flow of the second cooling medium flowing the second cooling medium channel to make a U-turn.
