Abstract

　L'objet de la présente invention est d'absorber facilement une contrainte thermique agissant dans la direction longitudinale d'un tube plat et d'empêcher la déformation provoquée quand une contrainte thermique agit dans la direction de la largeur du tube plat pendant le fonctionnement d'un échangeur de chaleur de type à ailette ondulée. Un moyen de renforcement (8) est formé au niveau des sections emplantures d'éléments latéraux (5) situés sur les deux côtés d'une partie centrale (4), et une partie d'absorption de contrainte (6) est formée sur chaque section paroi latérale (5b) des éléments latéraux (5) à un emplacement suffisamment éloigné d'une plaque tubulaire (3).
