Abstract

DISPOSITIF DE MÉLANGE POUR FLUIDE À GRADIENT DE TEMPÉRATURE ET SYSTÈME DE CONDITIONNEMENT D’AIR ASSOCIÉ L’invention concerne un dispositif de mélange comprenant un conduit (16) d’écoulement d’un fluide présentant un gradient de température selon une direction (24) de gradient entre une température minimale et une température maximale, et au moins un mélangeur (12) statique agencé à l’intérieur du conduit (16) d’écoulement comprenant une grille d’ailettes formée d’au moins trois rangées par au moins trois lignes d’ailettes pour homogénéiser la température du fluide, chaque rangée étant orientée selon une direction sensiblement parallèle à la direction (24) de gradient, chaque ailette d’une même rangée étant orientée selon une même direction préférentielle formant un angle compris entre cinq degrés et quarante-cinq degrés par rapport à une direction (18) d’écoulement du fluide, et chaque ligne comprenant des ailettes alternativement orientées selon une direction préférentielle opposée à la direction préférentielle de la ou des rangées adjacentes par rapport à la direction (18) d’écoulement du fluide. Figure pour l’abrégé : figure 1The invention relates to a mixing device comprising a conduit (16) for the flow of a fluid having a temperature gradient along a direction (24) of gradient between a minimum temperature and a maximum temperature, and at least one static mixer (12) arranged inside the flow conduit (16) comprising a grid of fins formed of at least three rows by at least three lines of fins to homogenize the temperature of the fluid, each row being oriented in a direction substantially parallel to the gradient direction (24), each fin in the same row being oriented in the same preferential direction forming an angle between five degrees and forty-five degrees with respect to a direction (18) of flow of the fluid, and each line comprising fins alternately oriented in a preferential direction opposite to the preferential direction of the adjacent row or rows with respect to the direction (18) d fluid flow.
