    Abstract: A cooling system (12) for a wind turbine (2), the cooling system (12) comprising: a fluid circuit (16) arranged to convey a working fluid to and from at least one component (14) of the wind turbine (2), to exchange heat between the working fluid and the component (14); a main pump (26) configured to circulate the working fluid around the fluid circuit (16); and at least one branch line (28) connected to the fluid circuit (16). The, or each, branch line (28) comprises: an inlet (30) arranged to receive working fluid from the fluid circuit (16); an outlet (32) arranged to return working fluid to the fluid circuit (16); a branch pump (36) arranged to pump working fluid through the branch line (28) from the inlet (30) to the outlet (32); and a cooling device (34) arranged to cool working fluid flowing through the branch line (28).

    Abstract: A fluid tank (12) for a wind turbine (2), the tank (12) comprising: a housing (14) enclosing 5 an interior volume (16) for holding liquid, the housing (14) comprising a vent (36) positioned above a maximum liquid surface level in the interior volume (16), to permit air flow between the interior volume (16) and the surrounding environment, in use; a barrier (38, 138, 238) extending across the interior volume (16) to divide the interior volume (16) into an upper volume (40) and a lower volume (42), wherein the barrier (38, 138, 238) is disposed 10 beneath a minimum liquid surface level in the interior volume (16). At least one passage (62, 68) is provided in the barrier (38, 138, 238) to allow fluids to flow between the upper and lower volumes (40, 42); and at least one opening (28, 32) through which liquid can be communicated into or out of the lower volume.

    Abstract: A wind turbine (10) includes a tower (12), a nacelle (14) coupled to the tower (12) and housing one or more heat generating components (18, 20), a rotor (16) having a least one wind turbine blade (24), and a cooler (38) mounted to the nacelle (14) and configured to cool the one or more heat generating components (18, 20) in the nacelle (14) by circulating a working fluid. The cooler (38) includes a support frame (46) coupled to the nacelle (14) and a heat exchanger (48) coupled to the support frame (46) and configured to cool the working fluid. The heat exchanger (48) includes at least two cooling panels (58) in non-planar relation with each other. The at least two cooling panels (50) may also be pivotably coupled to each other. A method of assembling a cooler (38) is also disclosed.
