Abstract
A wind power generation system includes: blades configured to be rotated by wind; a generator configured to be driven by the rotation of the blades to generate power; a nacelle supporting the blades; and a tower supporting the nacelle rotatably. The wind power generation system is configured to receive the wind at a side opposite to a side of the nacelle on which the blades are provided. The system includes a radiator configured to dissipate heat in the nacelle through a cooling medium. The radiator is provided outside the nacelle on an upwind side of the nacelle. The radiator is provided with an intake surface thereof facing an upwind direction. A path is formed downstream of the radiator to guide the wind that has passed the radiator.
