Methods and apparatus for cooling wind turbine generators

A wind turbine generator comprising:

• a stator comprising a core and a plurality of stator windings circumferentially spaced about a generator longitudinal axis;
• a rotor rotatable about the generator longitudinal axis, said rotor comprising a plurality of magnetic elements coupled to said rotor and cooperating with said stator windings, said magnetic elements configured to generate a magnetic field, said stator windings configured to interact with the magnetic field to generate a voltage in said stator windings;
• and
• a heat pipe assembly thermally engaging said stator to dissipate heat generated in said one of said stator and said rotor, said heat pipe assembly comprising a condenser section that extends radially outward with respect to a longitudinal axis of said generator.
