Abstract

L'invention concerne un support pour dispositif de ventilation (5) d'un véhicule automobile comportant une hélice (9), le support comportant une buse (11) présentant un orifice (19) configuré pour recevoir l'hélice (9), l'hélice (9) comportant une pluralité de pales (15) et étant configurée pour être entrainée en rotation dans l'orifice (19) de manière à générer un flux d'air primaire, les pales (15) étant soumises à au moins une force à une première fréquence lorsque l'hélice (9) est entrainée en rotation. Selon l'invention, la buse (11) présente à la périphérie de l'orifice (19), au moins une surface (30) présentant des discontinuités (33) agencées selon un motif périodique, configurée pour générer, au sein d'un flux d'air secondaire, dit flux d'air recirculant, s'écoulant entre les extrémités des pales (15) et la périphérie de l'orifice (19), au moins une contre-force à une deuxième fréquence en opposition de phase avec la première fréquence. L'invention concerne également un dispositif de ventilation (5) comprenant un tel support.The invention relates to a support for a ventilation device (5) of a motor vehicle comprising a propeller (9), the support comprising a nozzle (11) having an orifice (19) configured to receive the propeller (9), the support comprising a nozzle (11). propeller (9) comprising a plurality of blades (15) and being configured to be driven in rotation in the orifice (19) so as to generate a primary air flow, the blades (15) being subjected to at least one force at a first frequency when the propeller (9) is rotated. According to the invention, the nozzle (11) has at the periphery of the orifice (19), at least one surface (30) having discontinuities (33) arranged in a periodic pattern, configured to generate, within a secondary air flow, called recirculating air flow, flowing between the ends of the blades (15) and the periphery of the orifice (19), at least one counter-force at a second frequency in phase opposition with the first frequency. The invention also relates to a ventilation device (5) comprising such a support.
