Abstract (en)
A fan module (10) of a vehicle engine, the fixed shroud (12) of the module (10) receiving in a circular opening (16) a fan (14) rotating about a main axis (X), said opening (16) being circumvented by a peripheral wall (18) cylindrically extending in the downstream direction (DD) beyond the fan (14) toward a corner edge where said wall (18) angles radially and inwardly to extend toward a circular downstream edge. The downstream portion of the peripheral wall (18) forms an annular channel (C) opening in the upstream direction (UD), said channel (C) forming a continuous space to the gap (G) that is between the tips (22) of the blades (20) of the fan (14), said gap (G) being continuous, non-divided and non-partitioned.
