Abstract

L'invention concerne un appareil de ventilation à tornade comprenant : un ventilateur à tornade qui tourne autour d'un arbre rotatif ; et un ventilateur à rideau d'air qui entoure le ventilateur à tornade et qui tourne autour de ce dernier. Le ventilateur à rideau d'air comprend : une aube circonférentielle interne ; une aube circonférentielle externe ; une pluralité d'aubes radiales ; une première aube circonférentielle ; une seconde aube circonférentielle ; un couvercle supérieur ; et un couvercle inférieur. L'aube circonférentielle interne entoure le ventilateur à tornade et a une forme cylindrique creuse. L'aube circonférentielle externe s'étend radialement dans une direction circonférentielle en s'éloignant de l'aube circonférentielle interne. Les aubes radiales relient l'aube circonférentielle interne et l'aube circonférentielle externe l'une à l'autre et s'étendent le long d'une direction radiale, respectivement. Des première à quatrième aubes circonférentielles peuvent être alternativement reliées à une extrémité et à l'autre extrémité de chacune des aubes radiales. Le couvercle supérieur recouvre un espace entre la première aube circonférentielle et l'aube circonférentielle externe. Le couvercle inférieur recouvre un espace situé entre l'aube circonférentielle interne et la seconde aube circonférentielle.
