Abstract
The present invention relates to a wind turbine nacelle having a top face with a longitudinal extension in a wind direction, comprising a cooling device extending from the top face of the nacelle and a cover having at least one inner face. The cooling device is enclosed by the top face of the nacelle and the inner face of the cover.
Claims18
A wind turbine nacelle having a top exterior face with a longitudinal extension in a wind direction, comprising:
- a cooling device extending outwardly from the top face of the nacelle and being directly exposed to ambient wind flow, and
- a cover having at least one inner face, the cooling device being enclosed by the top face of the nacelle and the inner face of the cover,
- wherein at least one part of the cooling device is movable in relation to another part of the cooling device, the cover, or the top face of the nacelle.
A wind turbine nacelle having a top face with a longitudinal extension in a wind direction, comprising:
- a cooling device extending from the top face of the nacelle, and
- a cover having at least one inner face, the cooling device being enclosed by the top face of the nacelle and the inner face of the cover,
- wherein at least one part of the cooling device is movable in relation to another part of the cooling device, the cover, or the top face of the nacelle,
- wherein the cooling device has a first face which is pivotably connected to the cover.
A wind turbine nacelle having a top face with a longitudinal extension in a wind direction, comprising:
- a cooling device extending from the top face of the nacelle, and
- a cover having at least one inner face, the cooling device being enclosed by the top face of the nacelle and the inner face of the cover,
- wherein at least one part of the cooling device is movable in relation to another part of the cooling device, the cover, or the top face of the nacelle,
- wherein the cooling device has a centre of gravity and is connected with another part of the cooling device, the cover, or the top face of the nacelle in its centre of gravity.
A wind turbine nacelle having a top face with a longitudinal extension in a wind direction, comprising:
- a cooling device extending from the top face of the nacelle, and
- a cover having at least one inner face, the cooling device being enclosed by the top face of the nacelle and the inner face of the cover,
- wherein at least one part of the cooling device is movable in relation to another part of the cooling device, the cover, or the top face of the nacelle,
- wherein the movable part is a first part of the cooling device which is slidable in relation to a second part of the cooling device so that the first part is able to partly overlap the second part.
A wind turbine nacelle having a top face with a longitudinal extension in a wind direction, comprising:
- a cooling device extending from the top face of the nacelle, and
- a cover having at least one inner face, the cooling device being enclosed by the top face of the nacelle and the inner face of the cover,
- wherein at least one part of the cooling device is movable in relation to another part of the cooling device, the cover, or the top face of the nacelle,
- wherein the movable part is a door or a hatch pivotably connected to the cooling device or the cover.
A wind turbine nacelle having a top face with a longitudinal extension in a wind direction, comprising:
- a cooling device extending from the top face of the nacelle, and
- a cover having at least one inner face, the cooling device being enclosed by the top face of the nacelle and the inner face of the cover,
- wherein at least one part of the cooling device is movable in relation to another part of the cooling device, the cover, or the top face of the nacelle,
- wherein the cooling device is connected with another part of the cooling device, the cover, or the top face of the nacelle in at least one connection having a damper using hydraulic, pneumatic, or rubber, or a spring to control the movement of the cooling device.
A wind turbine nacelle having a top face with a longitudinal extension in a wind direction, comprising:
- a cooling device extending from the top face of the nacelle, and
- a cover having at least one inner face, the cooling device being enclosed by the top face of the nacelle and the inner face of the cover,
- wherein at least one part of the cooling device is movable in relation to another part of the cooling device, the cover, or the top face of the nacelle,
- wherein at least one part of the cover is movable in relation to another part of the cover, the cooling device, or the top face of the nacelle.
A wind turbine nacelle having a top face with a longitudinal extension in a wind direction, comprising:
- a cooling device extending from the top face of the nacelle, and
- a cover having at least one inner face, the cooling device being enclosed by the top face of the nacelle and the inner face of the cover,
- wherein at least one part of the cooling device is movable in relation to another part of the cooling device, the cover, or the top face of the nacelle,
- further comprising a plurality of cooling devices arranged with a mutual distance, and the distance between two cooling device is between 20 and 200 mm,
- wherein a hinge connection is arranged between at least two cooling devices.
