Abstract

Titre : Dispositif mélangeur favorisant une distribution homogène d’un mélange diphasique et échangeur de chaleur comprenant un tel dispositif L’invention concerne un dispositif mélangeur (3) pour distribuer un mélange d’une première phase (61) et d’une deuxième phase (62) d’un premier fluide (F1) globalement suivant une direction longitudinale (z) dans au moins un passage (10) d’un échangeur de chaleur (1), ledit dispositif mélangeur (3) comprenant au moins un canal latéral (31) configuré pour l’écoulement d’une première phase (61) du premier fluide (F1) à partir d’au moins une première entrée (311), une série de canaux longitudinaux (32) s’étendant suivant la direction longitudinale (z) et configurés chacun pour l’écoulement d’une deuxième phase (62) du premier fluide (F1) à partir d’une deuxième entrée (321) jusqu’à une deuxième sortie (322), lesdits canaux longitudinaux se succédant suivant une direction latérale (y) orthogonale à la direction longitudinale (z), et au moins un orifice (34) reliant fluidiquement ledit canal latéral (31) à au moins un canal longitudinal (32) de sorte que le dispositif mélangeur (3) est configuré pour distribuer un mélange de la première phase (61) et de la deuxième phase (62) par la deuxième sortie (322) dudit au moins un canal longitudinal (32). Selon l’invention, ledit au moins un canal longitudinal (32) est divisé, suivant la direction longitudinale (z), en au moins une portion amont (323) et une portion aval (324) ayant chacune une longueur (L3, L4) mesurée dans la direction longitudinale (z) et une largeur (D3, Dy) mesurée dans la direction latérale (y), la portion aval (324) étant agencée entre la portion amont (323) et la deuxième sortie (322), ladite portion aval (324) ayant, en tout point de sa longueur (L4), une largeur (Dy) supérieure à la largeur (D3) de la portion amont (323). Figure de l’abrégé : Fig. 4Title: Mixing device promoting homogeneous distribution of a two-phase mixture and heat exchanger comprising such a device The invention relates to a mixing device (3) for distributing a mixture of a first phase (61) and a second phase ( 62) of a first fluid (F1) generally in a longitudinal direction (z) in at least one passage (10) of a heat exchanger (1), said mixing device (3) comprising at least one side channel (31 ) configured for the flow of a first phase (61) of the first fluid (F1) from at least a first inlet (311), a series of longitudinal channels (32) extending in the longitudinal direction (z ) and each configured for the flow of a second phase (62) of the first fluid (F1) from a second inlet (321) to a second outlet (322), said longitudinal channels succeeding each other in a direction lateral (y) orthogonal to the longitudinal direction (z), and at least one orif ice (34) fluidically connecting said lateral channel (31) to at least one longitudinal channel (32) so that the mixing device (3) is configured to dispense a mixture of the first phase (61) and the second phase (62 ) through the second outlet (322) of said at least one longitudinal channel (32). According to the invention, said at least one longitudinal channel (32) is divided, along the longitudinal direction (z), into at least one upstream portion (323) and one downstream portion (324) each having a length (L3, L4) measured in the longitudinal direction (z) and a width (D3, Dy) measured in the lateral direction (y), the downstream portion (324) being arranged between the upstream portion (323) and the second outlet (322), said portion downstream (324) having, at any point along its length (L4), a width (Dy) greater than the width (D3) of the upstream portion (323).
