PROBLEM TO BE SOLVED: To provide a wind turbine generator system having a channel structure easy to ensure a cooling wind flow rate by a natural wind so as to materialize an effective cooling in a nacelle part.SOLUTION: The wind turbine generator system comprises: blades 1 rotating by receiving wind; a generator 5 driven by the rotation of the blades; a nacelle 6 for supporting the blades; and a tower 7 for supporting the nacelle rotatably, and receives wind from the side of the nacelle, opposite from the side on which the blades are disposed. In the wind turbine generator system, a radiator 13 is disposed on the external upstream side of the nacelle for radiating the heat in the nacelle through a coolant, the radiator is disposed to have a suction surface directed in the windward direction, and a passage for guiding the wind having passed through the radiator is formed in the wake flow of the radiator. 【課題】ナセル部において効果的な冷却を実現するために、自然風による冷却風量の確保がしやすいような流路構成を有する風力発電設備を提供する。【解決手段】風を受けて回転するブレード１と、前記ブレードの回転により駆動され発電する発電機５と、前記ブレードを支持するナセル６と、前記ナセルを回転可能に支持するタワー７を有し、前記ナセルの、前記ブレードが設置される側の反対側から風を受ける風力発電設備において、前記ナセルの外部風上側に前記ナセル内の熱を冷媒を介し放熱するラジエータ１３が設置され、前記ラジエータは吸込面が風上方向に向くように設置され、前記ラジエータの後流に、前記ラジエータを通過した風を導く流路が形成されていることを特徴とする。【選択図】図１
