Abstract:
1. A thermal conditioning system for an off-shore wind turbine comprising a nacelle air channel and at least one ambient air channel located between an outer wall and an inner wall of the nacelle, wherein the at least one ambient air channel has an inlet area and an outlet area both located outside the wind turbine nacelle preventing ambient air from entering in fluid communication with the air inside the wind turbine nacelle, an inlet port located inside the wind turbine nacelle and an outlet port located inside the wind turbine nacelle for circulating nacelle air in the nacelle air channel, heat exchanging zones formed by the nacelle air channel and the at least one ambient air channel being adjacent to one another at least one entry channel for the ambient air received in said inlet area, a front cover configured to redirect the ambient air from the at least one entry channel to the at least one ambient air channel, a back cover having at least one outlet zone for allowing the ambient air to exit the at least one ambient air channel once it has passed through said heat exchanging zones, and plates protruding from the base of a rear part of the nacelle that cooperate with the back cover to deflect the ambient air to pass through the at least one ambient air channel before exiting through the at least one outlet zone of the back cover, said heat exchanging zones being arranged to cool conductively or convectively the air inside the wind turbine nacelle.
