Abstract

L’invention concerne un ventilateur (1) centrifuge axial pour la circulation d’un gaz (G) comportant une enveloppe (2) tronconique pourvue d’un orifice d’aspiration (4) et d’un orifice de refoulement (6) alignés sur un axe (A), une turbine (13) centrifuge et un moteur (16) logé dans une cage-moteur (17). Il comporte un conduit axial (24) au moins en partie annulaire s’étendant dudit orifice d’aspiration (4) audit orifice de refoulement (6). Il est caractérisé en ce qu’il comporte un conduit radial (25) périphérique s’étendant à la sortie de ladite turbine (13) pour maintenir le flux de gaz (G) aspiré sous pression et le guider en direction dudit conduit axial (24) dans un écoulement laminaire, sans discontinuité, ni perte de pression. Il comporte en outre un déflecteur (30) disposé à l’intérieur dudit canal radial (25) pour orienter le flux de gaz (G) aspiré et générer une augmentation de pression complémentaire.
