  • Patent number: 11491862
    Abstract: A vehicle includes first and second seats supported by a frame, a cargo bed located more rearward than first and second seating portions of the first and the second seats, and a radiator located more rearward than the first and second seating portions and lower than a lower surface of the cargo bed. The radiator is located farther outward, in a width direction of the vehicle, than an engine that is located more rearward than a front end of the first and the second seats and at or substantially at a center of the vehicle in the vehicle width direction. The radiator includes an outer surface facing rearward and outward of the vehicle. A rotating fan to introduce air from outside the vehicle to inside the vehicle via the outer surface of the radiator is located on either one of an outer surface side and an inner surface side of the radiator.

  • Patent number: 11441476
    Abstract: A vehicle includes an air-path portion, an engine, and a rotating fan located more rearward than first and second seats. A wind pressure near the air-path portion located on a side surface of the vehicle is detected by a pressure sensor, and based on a detection result, an ECU controls a direction of rotation of the rotating fan. The rotating fan introduces/discharges air to/from an engine room via the air-path portion. If the pressure sensor detects a negative pressure, the rotating fan is controlled so as to discharge air from the engine room via the air-path portion. On the other hand, if the pressure sensor detects zero or a positive pressure, the rotating fan is controlled so as to introduce air to the engine room from the air-path portion.
