Title
(EN) TUBE OF A HEAT EXCHANGER AND HEAT EXCHANGER COMPRISING SUCH A TUBE
(FR) TUBE D'ÉCHANGEUR DE CHALEUR ET ÉCHANGEUR DE CHALEUR COMPRENANT UN TEL TUBE
Abstract
(EN)
The invention relates to a tube (6) of a heat exchanger, the tube (6) extending mainly along a longitudinal direction and the tube (6) extending between two opposite lateral edges (21, 22) of the tube (6). The tube (6) comprises a plurality of canals (15a, 15b) that are parallel to the longitudinal direction. The tube (6) comprises a single first rank canal (15a) that is delimited by at least a first lateral edge (21) of the tube (6) and two first rank side walls (16a). The tube (6) comprises at least a second rank canal (15b) that is delimited by at least two second rank side walls (16b). A thickness (19) of both first rank side walls (16a) of the first rank canal (15a) is bigger than a thickness (19) of any second rank side wall (16b) of a second rank canal (15b) of the tube (6) and a thickness (19) of the first lateral edge (21) of the tube (6) is bigger than a thickness (19) of any second rank side wall (16b) of a second rank canal (15b). The tube (6) is obtained by folding a single sheet (23).

L'invention concerne un tube (6) d'un échangeur de chaleur, le tube (6) s'étendant principalement le long d'une direction longitudinale, et le tube (6) s'étendant entre deux bords latéraux opposés (21, 22) du tube (6). Le tube (6) comprend une pluralité de canaux (15a, 15b) parallèles à la direction longitudinale. Le tube (6) comprend un canal unique de premier rang (15a) délimité par au moins un premier bord latéral (21) du tube (6) et deux parois latérales de premier rang (16a). Le tube (6) comprend au moins un canal de second rang (15b) délimité par au moins deux parois latérales de second rang (16b). Une épaisseur (19) des deux parois latérales de premier rang (16a) du canal de premier rang (15a) est supérieure à une épaisseur (19) de toute paroi latérale de second rang (16b) d'un canal de second rang (15b) du tube (6), et une épaisseur (19) du premier bord latéral (21) du tube (6) est supérieure à une épaisseur (19) de toute paroi latérale de second rang (16b) d'un canal de second rang (15b). Le tube (6) est obtenu par pliage d'une feuille unique (23).
