Abstract

On déforme deux bandes métalliques (3, 4) à profil ondulé en leur donnant une forme de spirale. En même temps, une première bande plate (7) et une deuxième bande plate (8) subissent un écrouissage de sorte que chacune forme une spirale plate dont les spires décrivent le même plan. Ces spirales plates (7, 8) forment le plafond et le plancher d'un premier canal (1) pour le fluide de l'échangeur de chaleur et sont reliées par un procédé de travail en continu aux bandes métalliques (3, 4) par leurs bords longitudinaux respectifs. On obtient ainsi un premier canal (1) en forme de spirale. Entre les spires de ce canal (1), on dispose des bandes plates supplémentaires (9, 10) déformées en spirales plates également, que l'on fixe par leurs bords sur la portion angulaire du premier canal (1) pour le fluide. De la sorte, un deuxième canal (2) pour le fluide est constitué. Ce procédé étant continu, la fabrication d'un tel échangeur de chaleur est extrêmement économique.
