Abstract: A reserve tank includes a vapor-liquid separator, an inlet portion, an outlet portion, and a protrusion. The vapor-liquid separator defines an inner space for separating a vapor phase and a liquid phase of a cooling water. The inlet portion defines a first opening through which the cooling water is supplied into the inner space and the outlet portion defines a second opening through which the cooling water is discharged from the inner space. The protrusion protrudes upward from a bottom surface of the vapor-liquid separator. An inner circumferential surface of the vapor-liquid separator and an outer circumferential surface of the protrusion are coaxially provided to define an annular passage in the inner space. The cooling water introduced from the first opening flows spirally in the annular passage.

Abstract: An air cooling device includes a first inlet surge tank, a first heat exchanger to cool air introduced from the first surge tank, a second inlet surge tank, a second heat exchanger to cool air introduced from the second surge tank, and an outlet surge tank. The outlet surge tank receives both of airs introduced from the first heat exchanger and the second heat exchanger and the airs flows from the outlet surge tank toward an internal combustion engine. The outlet surge tank includes a merging space and a fixing hole. The merging space is where the airs introduced from the first heat exchanger and the second heat exchanger merge with each other. A fastening member to fasten the outlet surge tank passes through the fixing hole from an outer surface of the outlet surge tank away from the merging space toward the internal combustion engine.

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.

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: 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.
