A cooling system for a wind turbine is provided. The cooling system includes at least one generator having a plurality of external fins disposed around at least a portion of the periphery of the generator. A shroud is disposed around at least a portion of the generator, and is configured to guide air across the external fins so that said air cools the generator.

What is claimed is: 1. A cooling system for a wind turbine, comprising: at least one generator having a plurality of external fins disposed around at least a portion of the periphery of said at least one generator, the plurality of external fins connected to the at least one generator; a shroud disposed around at least a portion of said at least one generator and at least a portion of the plurality of external fins; at least one fan in fluid communication with said shroud, said at least one fan operative to create a suction to draw air into said shroud and across said plurality of external fins; a housing of the at least one generator connected to a housing of a gearbox and a compact geared drive train is formed by the at least one generator and the gearbox; a braking system connected to a shaft of said at least one generator, said shroud enveloping at least a portion of said braking system; and wherein said shroud is configured to guide air across at least a portion of said plurality of external fins so that said air cools said at least one generator. 2. The cooling system of claim 1, further comprising: at least one exhaust duct connected between said at least one fan and an exterior of a nacelle of said wind turbine. 3. The cooling system of claim 1, further comprising: at least two fans in fluid communication with said shroud, said at least two fans operative to create a suction to draw air into said shroud and across said plurality of external fins; and at least two exhaust ducts connected between said at least two fans and an exterior of a nacelle of said wind turbine. 4. The cooling system of claim 1, further comprising: said at least one fan connected to said generator, said at least one fan operative to create a suction to draw said air into said shroud and across said plurality of external fins. 5. The cooling system of claim 1, further comprising: a plurality of gearbox external fins disposed around at least a portion of the periphery of said gearbox; wherein at least a portion of said shroud is disposed around at least a portion of said gearbox. 6. The cooling system of claim 1, wherein said at least one generator is chosen from one or more of: permanent magnet generator, permanent magnet synchronous generator, induction generator, wound-field synchronous generator and doubly-fed asynchronous generator. 7. The cooling system of claim 1, further comprising: at least one vent in a nacelle of said wind turbine, said at least one vent comprising a filter to filter air entering said nacelle. 8. A wind turbine having a cooling system, said cooling system comprising: at least one generator having a plurality of external fins disposed around at least a portion of the periphery of said at least one generator, the plurality of external fins connected to the at least one generator; a shroud disposed around at least a portion of said at least one generator and at least a portion of the plurality of external fins; at least one fan in fluid communication with said shroud, said at least one fan operative to create a suction to draw air into said shroud and across said plurality of external fins; at least one vent in a nacelle of the wind turbine, the at least one vent comprising a filter to filter air entering the nacelle; and wherein said shroud is configured to guide air across at least a portion of said plurality of external fins so that said air cools said at least one generator. 9.
