  • Patent number: 8903599
    Abstract: A failure determination device capable of performing failure determination for a shutter device of a vehicle with accuracy in a short time period. In an engine room of a vehicle, a condenser for a refrigeration cycle for an aircon is provided and at a front grille of the vehicle, a grille shutter device is provided for introducing ambient air for cooling the condenser into the engine room by opening a grille shutter. According to the failure determination device of the shutter device, a pressure of the refrigerant discharged from the condenser is detected as a refrigerant pressure. A failure of the grille shutter device is determined based on the refrigerant pressure, which changes at a large rate according to the opening/closing of the grille shutter, enabling failure determination with accuracy in a short time period.

    Abstract: To provide a vehicle front portion structure that efficiently cools a cooling unit. A duct, whose upper end opens at a cowl panel side and whose lower end opens above a vehicle front side of a cooling unit, is provided at a vehicle front portion. A blower fan is provided at an intermediate portion of the duct. The blower fan is rotated, and external air, that has been drawn-in from a cowl side, can be blown as cooling wind from a lower end side of the duct toward a condenser and a radiator. Therefore, heat exchange efficiency can be improved as compared with a case of only traveling wind that is introduced in from an opening of a front bumper cover.

  • Publication number: 20140299075
    Abstract: An air intake adjusting system for a motor vehicle includes a plurality of struts which are arranged at distances from one another and can each be rotated about an axis of rotation such that, in a first position of the struts, the air intake adjusting system is open and, in a second position of the struts, the air intake adjusting system is closed. The struts each have a rotating section, through which the axis of rotation of the respective strut extends, and a flap section, which extends from the rotating section and, in the second position, rests against the rotating section of an adjacent strut. The rotating sections of the struts each have a first side and a second side which, when the struts are in the second position, converge against an intended approach flow direction of the air intake adjusting system such that they form an approach flow edge.

  • Publication number: 20140230759
    Abstract: A system for removing heat from the engine compartment (9) of a heavy duty truck. A first ventilating system removes heat from the radiator. It is isolated from a second ventilating system that removes heat from the engine compartment. The first system takes heat from the radiator through a plenum by centrifugal squirrel cage blowers, and is directs it out to ambient by ductwork. The second system draws ambient air generally from back to front of the engine compartment, preferably by cowl induction, without the use of ram air from the vicinity of the radiator. The exits of the two systems are into a slip stream of the heavy duty truck, and the exit of the second ventilating system is into a slip stream of the first, to scavenge air out of the engine compartment.
