Abstract:
1. A nacelle with improved cooling for a wind turbine, comprising: a reservoir housing having an outer surface and an inner surface; at least two reservoir chambers are formed in said inner surface, said at least two reservoir chambers are sized to receive cooling liquid, at least one liquid cooling passage for fluid communication between said at least two reservoir chambers, at least one heat generating device is contained within the nacelle of the wind turbine and being cooled by the cooling liquid within at least one of said two reservoir chambers; a plurality of exterior cooling fins extending from said outer surface, each one of said plurality of exterior cooling fins including a hollow body, an inlet port and exhaust port; and a means for pumping cooling liquid from at least one of said at least two reservoir chambers into said inlet ports of said plurality of exterior cooling fins, said cooling liquid exiting said exhaust port into at least one of said at least two reservoir chambers, wherein ambient air passing over said plurality of exterior cooling fins reduces a temperature of the cooling liquid.
