Abstract

On décrit un échangeur (8) de chaleur à doubles tubes feuilletés qui est capable d'empêcher un milieu d'échange de chaleur combustible de fuir à l'extérieur et qui comprend des éléments (25) de tubes et des nervures (26) qui sont alternativement couchées les unes sur les autres, chaque tube comportant un premier chemin (65) d'écoulement comprenant une paire d'unités de réservoir (66a, 66b) prévues sur un côté terminal d'un tube (25) et un chemin (67) d'écoulement inter-réservoirs qui assure la communication entre les unités de réservoir et un deuxième chemin d'écoulement formé de manière à entourer le premier chemin (65) d'écoulement. Un liquide réfrigérant combustible est mis en circulation dans le premier chemin (65) d'écoulement et une saumure soluble servant à dissoudre et à absorber le liquide réfrigérant combustible est mis en circulation dans le deuxième chemin (70) d'écoulement.
