Definitions

  • the invention relates to a valve device for a motor vehicle having a housing, a befindli ⁇ chen in the housing flow channel, with a arrange in the flow channel ⁇ th flap for closing the flow channel, wherein the flap is fixed to a shaft which is rotatable in the housing is mounted and connected to a gear which is driven by an electric motor.
  • valve devices are used for example as Dros ⁇ selklappenstutzen, exhaust gas recirculation valve or valves for charging ⁇ air cooler use and have long been known. Because of the sometimes high temperatures of the gas passing the flow channel gases such valves have a water cooling to protect temperature sensitive components of the valve device, such as plastic gears of the gear unit or a sensor for angle of rotation determining the shaft, against an excessively high temperature ⁇ load.
  • the disadvantage here are the neces ⁇ sary cooling channels in the housing, which inevitably increase the cost and the construction ⁇ space of the housing. Also, the effort in production, assembly and hydraulic interconnection for the ⁇ on closing coolant lines is significant.
  • the invention is therefore based on the object mini ⁇ mieren the cost of cooling the valve device mentioned above.
  • the object is achieved in that a heat sink is provided on or in the Ventilvor ⁇ direction.
  • the introduced by the flowing gas in the valve device heat is targeted to the Heat sink passed.
  • the thermal stress can be reduced less temperature-resistant components of the Ven ⁇ tilvorraum.
  • the advantage is that since ⁇ by active cooling with a cooling medium which flows through cooling channels arranged in the housing, ⁇ who can dispense the. This simplifies the design of the housing of the valve device, whereby the housing is easier to produce, and it requires with the elimination of the cooling channels less space. In addition, eliminates the connections with the required coolant lines, whereby the volume of the cooling circuit in the motor vehicle decreases.
  • the heat sink is an over the strength of the housing beyond material accumulation in Ge ⁇ housing. With this increased accumulation of material, an area with increased heat capacity is created, which can absorb the heat introduced into the housing. For a long-term passive cooling, the heat is transferred from the heat sink or released to the environment.

  • the heat sink is arranged in a ⁇ on their component, and the housing of the valve device is connected to this component.
  • the heat from the flow channel through the housing to the other component ge ⁇ passes and thus kept away from the less temperature-resistant components of the valve device.
  • An advantageous embodiment is to connect a flange upstream of the flow channel.
  • This flange can form the heat sink even with a suitable design or serve as a transmission element by connecting the Ventilvor ⁇ direction with another, serving as a heat sink component.
