Abstract: A heat exchanger assembly for cooling a heat-generating component, such as a generator or power electronics module, within a wind turbine nacelle comprises a thermoelectric element, such as a Peltier element, having a first section arranged in a first region of relatively high temperature in contact with the heat-generating component or in the vicinity thereof, and a second section arranged in a second region of a relatively low temperature. The thermoelectric element is configured to transfer heat from the first region of relatively high temperature to the second region of relatively low temperature with consumption of electrical energy. A source of electrical energy is provided for the thermoelectric element, and a control unit may be provided for controlling the energy supply in order to control the temperature of the component or surface area cooled by the thermoelectric element. A further cooling element including a so-called heat pipe may be provided to enhance cooling efficiency.

Abstract: A hinged connection apparatus is described for securing a first wind turbine component to a second. The first wind turbine component may be a wind turbine blade and the second wind turbine component may be a control surface such as an aileron. The first or second wind turbine component comprises at least one hinge housing (15) in which an electrically sensitive component, such as a cable or an electrical activated hinge pin, is retained. Preferably, the interior portion of the hinge housing (30) is made of a glass fibre composite material that is fatigue resistant and electrically non-conductive. The exterior (31) of the hinge housing on the other hand is preferably electrically conductive. Furthermore, an extendable conductive or non-conductive sleeve (32) may be provided to bridge the gap in-between one hinge housing and an adjacent hinge housing.

Abstract: A hinged connection apparatus is described for securing a first wind turbine blade component to a second. The first wind turbine component may be a wind turbine blade body (10) and the second wind turbine component may be a control surface such as an aileron (11). The first or second wind turbine blade component comprises at least one hinge housing in which a rotary actuator (26) is retained. The rotary actuator (26) may comprise a motor, or in alternative embodiments a material that changes its shape under the influence of an external stimulus, such as a piezo-electric element or a memory alloy. The rotary actuator may be provided as part of the hinge pin connecting the first component to the second.

Abstract: A hinged connection apparatus is described for securing a first wind turbine component to a second. The first wind turbine component may be a wind turbine blade (10) and the second wind turbine component may be a control surface such as an aileron (11). The first or second wind turbine component comprises at least one hinge housing in which a hinge pin (16, 26) is retained. The hinge pin (16, 26) may be extended from a retracted position into an extended position in which it engages with a hinge recess on the other wind turbine component to form a connection. A locking mechanism is provided for securing the hinge pin in place. The hinge pin may be extended manually or automatically by an actuator.
