Abstract

Ce dispositif (10) comporte un ventilateur (12) comportant un caisson (14) logeant une hélice (16) rotative autour d'un axe de rotation (Z-Z), ledit caisson (14) présentant une entrée (18) de fluide gazeux par laquelle le fluide gazeux est destiné à s'engouffrer dans le ventilateur (12), sensiblement parallèlement à l'axe de rotation (Z-Z), et une sortie (19) de fluide gazeux par laquelle le fluide gazeux est destiné à être expulsé. Il comporte un circuit (20) de circulation de fluide gazeux, comprenant une conduite principale (22) et des moyens (23) de déviation de flux (F) de fluide gazeux, tels que : - la conduite principale (22) s'étend le long d'une direction d'écoulement (D) formant un angle non nul avec l'axe de rotation (Z-Z), et - les moyens de déviation (23) dévient un flux (F) issu de la conduite principale (22), pour l'orienter sensiblement parallèlement à l'axe de rotation (Z-Z).
