Abstract

L'invention concerne un insert d'échangeur de chaleur-mélangeur, respectivement un ensemble insert d'échangeur de chaleur-mélangeur, ainsi qu'un échangeur de chaleur-mélangeur comprenant un ensemble insert d'échangeur de chaleur-mélangeur correspondant, qui présentent un comportement amélioré de mélange et de thermorégulation et présentent une tendance à l'encrassement réduite, l'insert d'échangeur de chaleur-mélangeur comportant un premier groupe de plaques à corps creux (10, 11) présentant un volume interne (13) et un deuxième groupe de plaques à corps creux (20, 21) présentant un volume interne (23), les plaques à corps creux (10, 11) du premier groupe étant inclinées dans une première direction (R1) par rapport à une direction longitudinale (L) de l'insert d'échangeur de chaleur-mélangeur (1), les plaques à corps creux (20, 21) du deuxième groupe étant inclinées dans une deuxième direction (R2) par rapport à une direction longitudinale (L) de l'insert d'échangeur de chaleur-mélangeur (1), les plaques à corps creux (10, 11) du premier groupe étant contiguës latéralement aux plaques à corps creux (20, 21) du deuxième groupe et les volumes internes (13) des premières plaques à corps creux (10, 11) étant reliés aux volumes internes (23) des deuxièmes plaques à corps creux (20, 21), de telle sorte que les volumes internes (13) du premier groupe et les volumes internes (23) du deuxième groupe fassent partie d'un volume interne (13, 23) total d'un seul tenant qui est conçu pour guider un fluide de thermorégulation.
