Abstract:
An aerogenerator with a rotor of blades which turn connected to devices for converting wind energy into energy of another type incorporating a wind-channeling conduit (22) having a wind intake zone and a wind outlet zone characterised in that:a) the wind intake zone is made up of a first area (43, 60) to receive the wind, with a constant cross-section; a second area (44, 61) to accelerate the wind flow, with a first part (45, 62) with a progressively decreasing cross-section, a second part (46, 63) with a constant cross-section, at the end of which the rotor (30, 52) is situated, said areas being shaped so that the accelerated wind flow will have a direction perpendicular to the sweeping plans of the rotor (30, 52); b) the wind outlet zone is made up of a a third area (47, 64) with a first part with a constant cross-section, a second part with progressively increasing cross-section and a fourth area (48, 65) with a constant cross-section, the shape of said third and fourth areas being appreciably symmetrical with respect to the sweeping plane of the rotor to the second and first areas of the wind intake zone, respectively.
