Abstract: In an intake air cooling device, a heat-exchanging core portion in an intercooler has an intake-air downstream-side core portion and an intake-air upstream-side core portion located upstream of the intake-air downstream-side core portion in a flow of intake air. The intake-air downstream-side core portion is located upstream of the intake-air upstream-side core portion in a flow of a cooling fluid. The intercooler has a U-turn portion at which a flow direction of the cooling fluid turns around between the intake-air downstream-side core portion and the intake-air upstream-side core portion. A flow rate control device intermittently supplies the intercooler with a predetermined volume of the cooling fluid at a time. The predetermined volume is a value determined on basis of a volumetric capacity of a cooling fluid channel in the intake-air downstream-side core 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.

Abstract: A cooling system includes multiple heat exchangers, a shutter, and a controller. The controller determines whether an amount of air flowing to the other heat exchanger needs to be increased and controls an opening degree of the shutter in a closing direction to reduce an amount of air flowing to a specified heat exchanger and increase an amount of air flowing to another heat exchanger upon determining that the amount of air flowing to the other heat exchanger needs to be increased.

Abstract: In a heat exchange unit, a shutter device is disposed on a vehicle front side with respect to a coolant heat exchanger to open and close a passage for traveling air directed toward the coolant heat exchanger. A blower is switchable between a first blowing state in which air flows from the vehicle front side to the vehicle rear side and a second blowing state in which air flows from the vehicle rear side to the vehicle front side. In a case where a switch that makes a vehicle travelable is in an on state, a control unit switches the blower to the second blowing state, while an open degree of the shutter device is set at a closing side from a maximum open degree of the shutter device when a temperature of the engine coolant is equal to or lower than a predetermined temperature determination value.

Abstract: A measurement device includes a frame member rotatably supported about a first axis line, a detection body disposed inside of the frame member and rotatably supported relative to the frame member about a second axis line, and a vane disposed on one end side of the detection body in a direction orthogonal to the second axis line and that directs the other end side of the detection body in the direction orthogonal to the second axis line toward an air flow upstream side upon receiving an air flow. The measurement device includes a wind direction sensor disposed in the detection body that detects a wind direction as a direction of the other end side of the detection body in the direction orthogonal to the second axis line, and a wind speed sensor disposed in the detection body that detects a wind speed of the air flow.

Abstract: A cooling device for an automobile that includes a front opening opened in a front engine room, a first air blower arranged in the front engine room on a front side of a drive engine, and an introduction passage for guiding, toward the first air blower, air to flow from the front side of the front opening through the front opening is configured to cool the drive engine with the air flow passing from the introduction passage to the drive engine via the first air blower. The cooling device includes a duct having a first opening opened in the introduction passage and a second opening opened to rear of the drive engine in the front engine room, to form an air passage for air to flow between the first opening and the second opening.
