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

Abstract: An air conditioner includes: a heat pump cycle including a compressor, a heating part and a low-temperature side water-refrigerant heat exchanger; a heat medium circuit; and a blower. In the air conditioner, when a heating capability of the heating part is increased by using the heat generated by the heat generating part, a heating preparation control is executed, in which a refrigerant discharge capability of the compressor is set to be equal to or less than a predetermined reference discharge capability and a blowing capability of the blower is set to be equal to or less than a predetermined reference blowing capability, until an inlet-side heat medium temperature of the heat medium flowing into the heat medium passage of the low-temperature side water-refrigerant heat exchanger becomes equal to or higher than a target heat medium temperature.

Abstract: A reserve tank includes a gas-liquid separator, a flow inlet portion, a flow outlet portion, and a projection shaped in a tubular form. The gas-liquid separator is shaped in a bottomed tubular form and is centered on a predetermined axis. The flow inlet portion is configured to conduct coolant into an inside of the gas-liquid separator. The flow outlet portion is configured to discharge the coolant from the inside of the gas-liquid separator. The projection extends along the predetermined axis from a bottom wall at the inside of the gas-liquid separator. An inner space of the projection opens to an inner space of the gas-liquid separator at a distal end portion of the projection.

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: 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: 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: 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.
