A downwind rotor type wind power generation device (100) which allows a nacelle (104) to be transported and installed more conveniently without the need for troublesome detachment and reattachment of a heat exchanger (134) and also improves the efficiency in cooling a generator (124). The downwind rotor type wind power generation device (100) includes a rotor (102) having a hub (112) and a plurality of blades (114) extending radially from the hub, a nacelle (104) having a generator (124) for converting the rotational energy of the rotor into electric energy and a heat exchanger (134) for exchanging heat with heat generated at least by the generator and supporting the rotor rotatably, and a tower (106) supporting the nacelle rotatably around a vertical axis (160) so that the rotor is positioned downwind. The heat exchanger is located on the opposite side of the rotor with respect to the vertical axis and exposed. |
