Abstract: A wind turbine has a nacelle which houses operative components such as a transformer or converter which in use generate unwanted heat, the nacelle including an external nacelle cover (20) to form the outer nacelle enclosure, and provided with a panel (24) which overlies a bottom cover (22) region forming therewith a conduit for directing external air to one or more of the heat generating operative components for cooling purposes.

Abstract: A nacelle for a wind turbine, the nacelle comprising a roof panel forming an opening into an internal space; a cooling arrangement extending upwards from the roof panel; and a closure movable between an open position revealing the opening and a closed position closing the opening. To enable easy parking of the closure and particularly to enable parking of the closure in a position where it does not occupy a large surface space on the roof panel, the nacelle further comprises a track configured to guide the closure between the open and the closed positions, the track being carried at least partly by the cooling arrangement.
