CA 2592077

An omni-directional, vertical discharge wind turbine assembly (1) including a shroud that includes a diffuser (9) and the structure surrounding and defining the collection chamber (12) that captures wind in any direction and directs it to flow vertically via stacked curved blades of toroidal form (10a-10e). The blades (10a-10e) are secured by vertical walls (6.1-6.3). The diffuser (9) is connected downstream of the rotor (3) and it expands in cross section in the direction of airflow. Wedge (41) and a collar (40) are formed near the outlet of the diffuser (9). The wedge (41) and collar (40) assist in increasing the airflow through the rotor by deflecting the free wind flowing across the outlet of the diffuser.

L'invention porte sur un ensemble aérogénérateur (1) à évacuation verticale, omnidirectionnel, comprenant un carénage qui comprend un diffuseur (9) et la structure entourant et formant la chambre de récupération (12) qui capture le vent dans n'importe quelle direction et le dirige de façon à l'écouler verticalement par l'intermédiaire de pales courbes empilées de forme toroïdale (10a-10e). Les pales (10a-10e) sont fixées par l'intermédiaire des parois verticales (6.1-6.3). Le diffuseur (9) est raccordé en aval du rotor (3) et s'étend dans la section transversale du sens de l'écoulement d'air. Une arête rapportée (41) et un col (40) sont formés à proximité de l'orifice d'évacuation du diffuseur (9). L'arête rapportée (41) et le col (40) facilitent l'accroissement de l'écoulement d'air dans le rotor en faisant dévier le vent non canalisé qui s'écoule par l'orifice d'évacuation du diffuseur.
