An offshore wind turbine (1) includes a tower structure body configured with a tower (4) and foundation (5), a rotor (2) supported at the tower top, a generator generating electricity by the rotor's rotation, and a converter (7) converting generated electricity. A cavity is formed in the tower (4) and foundation (5), and an internal space configured therewith is divided into upper and lower chambers (A, B) by a bulkhead (5a) having first and second vents (5b, 5c) between or in either of the tower (4) and foundation (5). The converter (7) is disposed in the upper chamber (A). An air circulating channel and blower (e.g., exhaust fan 8) are provided wherein air is circulated from the converter (7) to the lower chamber (B) through the first vent (5b), then to the converter (7) through the second vent (5c). An air inlet (10a) is disposed below an air outlet (9a), or a partition member (12) is provided therebetween. |
