VENTILATION SYSTEM WITH REDUCED AXIAL SPACE REQUIREMENT

摘要

This device (10) comprises a fan (12) comprising a box (14) housing a propeller (16) rotatable about an axis of rotation (ZZ), said box (14) having an inlet (18) of gaseous fluid by which the gaseous fluid is intended to rush into the fan (12), substantially parallel to the axis of rotation (ZZ), and an outlet (19) of gaseous fluid through which the gaseous fluid is intended to be expelled. It comprises a circuit (20) for circulating gaseous fluid, comprising a main pipe (22) and means (23) for deflecting flow (F) of gaseous fluid, such that: - the main pipe (22) extends along a flow direction (D) forming a non-zero angle with the axis of rotation (ZZ), and - the deflection means (23) deflect a flow (F) from the main pipe (22) to orient it substantially parallel to the axis of rotation (ZZ).
