Abstract

Un dispositif de ventilation (2) destiné à générer un flux d'air vers un échangeur de chaleur (1) de véhicule comprend des conduits (8) ayant une section géométrique comprenant un bord d'attaque (37), un bord de fuite (38), et des premier (42) et deuxième (44) profils, entre le bord d'attaque (37) et le bord de fuite (38). Chaque conduit (8) a une première ouverture (40) sur le premier profil (42), telle qu'un flux d'air sortant de la première ouverture (40) s'écoule le long du premier profil (42) et une deuxième ouverture (40) sur le deuxième profil (44), telle qu'un flux d'air sortant de la deuxième ouverture (40) s'écoule le long du deuxième profil (44). La section géométrique de chaque conduit (8) définit une section de passage (S) du flux d'air traversant ledit conduit (8), qui a une aire supérieure ou égale à 200 mm2 et inférieure ou égale 900 mm2.
