Abstract

L'invention concerne un ventilateur. Le boîtier (17) d'un ventilateur (1) comporte une face frontale (2) côté flux entrant, une face frontale (16) côté flux sortant, et une bague de paroi (15) limitant un passage du ventilateur et s'étendant en direction d'un axe (12) allant d'une face frontale (2) à l'autre (16). Une roue (10) de ventilateur est agencée dans le passage de ventilateur. Un registre (3) est agencé sur la face frontale (2) côté flux entrant et présente un moyeu (8) positionné de manière centrale dans le passage de ventilateur et des entretoises primaires (4) et des entretoises secondaires (6) s'étendant dans la direction radiale entre le moyeu (8) et le bord du passage de ventilateur, lesquelles entretoises secondaires croisent les entretoises primaires (4).
