[Abstract] A downwind rotor type wind power generation device which allows a nacelle to be transported and installed more conveniently without the need for troublesome detachment and s reattachment of aheat exchanger andalso improves the efficiency in cooling a generator. The downwind rotor type wind power generation device includes a rotor having a hub and a plurality of blades extending radially from the hub, a nacelle having a generator for converting the rotational energy of the rotor 10 into electric energy and a heat exchanger for exchanging heat with heat generated at least by the generator and supporting therotorrotatably, andatowersupportingthenacelle rotatably around a vertical axis so that the rotor is positioned downwind. The heat exchanger is located on the opposite side of the rotor L5 with respect to the vertical axis and exposed. 10_4 150 153a 150a 116 112 16138 120 122a FORWARD BACKWARD (UPWIND) (DOWNWIND) |
