Wind turbine and method for constructing a wind turbine

Abstract

Wind turbine comprising a first cover (2) delimiting an elevated pressure area (3), pressurization means (4) for increasing the pressure in the elevated pressure area (3) and a generator (6) with a stator (7) and an external rotor (8), wherein the stator (7) is mounted in a fixed position with respect to the first cover (2) and wherein the stator (7) comprises at least one inflow opening (9, 10) that is open to the elevated pressure area (3), therefore allowing air from the elevated pressure area (3) to flow into the stator (7) to cool the generator (6), wherein a second cover (11) that is attached to the stator (7) or a hollow section (33) of the stator (7) extends axially into a receiving opening (12) of the first cover (2), wherein a sealing means (13) is arranged between the first cover (2) and either the second cover (11) or the hollow section (33) to seal the elevated pressure area (3), wherein the rotational axis (14) of the external rotor (8) extends through the elevated pressure area (3), wherein the inflow opening (9, 10) is arranged at a smaller distance from the rotational axis (14) than the second cover (2) or the hollow section (33).
