Abstract

L'invention concerne un échangeur de chaleur stratifié constitué par stratification d'une pluralité de plaques tubulaires. Ces plaques tubulaires sont constituées d'une première et d'une seconde feuille. Un trajet d'écoulement de fluide dans la direction de stratification relié à une extrémité dans la direction de stratification, est formé, et un trajet d'écoulement de fluide circulaire relié au trajet d'écoulement de fluide dans la direction de stratification entre la première et la seconde feuille, est formé. La première feuille d'une plaque tubulaire et la seconde feuille d'une autre plaque tubulaire, qui sont stratifiées de manière adjacente, sont liées par une partie de liaison au niveau d'une partie extrémité côté opposé au trajet d'écoulement de fluide dans la direction de stratification. Cette partie de liaison, et la première ainsi que la seconde feuille liées par cette dernière, sont formées par un élément plaque.
