Abstract
A wind turbine with a tower and a nacelle with a nacelle housing is provided. The nacelle is placed on the tower. Further provided is a cooling flap, which is configured to close an opening in or on the area of the wind turbine to be cooled. At least one temperature-dependent passive actuator is configured to activate and open the cooling flap as a function of temperature, so as to enable a heat compensation in the area to be cooled by means of the opening. The temperature-dependent passive actuator can change its shape and/or its length without any external electrical energy as a function of temperature.
Claims9
A wind turbine, comprising:
- a tower;
- a nacelle with a nacelle housing, which is placed on the tower;
- at least one cooling flap, which is configured to close an opening in or on an area of the wind turbine to be cooled;
- and
- at least one temperature-dependent actuator, which is configured to activate and open the cooling flap as a function of temperature, so as to enable a heat compensation in the area to be cooled by means of the opening,
- wherein the temperature-dependent passive actuator can change its shape and/or its length without external electrical energy as a function of the temperature.
A method for controlling a wind turbine, wherein the wind turbine has a tower, a nacelle and an area with an opening and at least one cooling flap for closing the opening, wherein a passive temperature-dependent actuator is provided on the cooling flap, the method comprising:
- temperature-dependent activation of the passive, temperature-dependent actuator;
- and
- opening the cooling flap via a temperature-dependent length expansion or change in shape of the passive temperature-dependent actuator,
- so as to enable a heat compensation in the area of the wind turbine.
