The present invention relates to a tube (1) made of a profile rolled metal product, in particular for use in heat exchangers, a rolled metal product and a method of producing the same. The tube (1) includes a first wall (2) and a second wall (4) forming two opposing sides of the tube, and a plurality of reinforcing structures connecting the first and second walls (2, 4) and forming longitudinal passages (10) between them. Each reinforcing structure is formed by a longitudinal ridge (6) on the first wall (2) projecting towards the second wall (4) and a longitudinal ridge (8) on the second wall (4) protecting towards the first wall (2). The ridges (6, 8) are joined to each other at their sides.
L'invention concerne un tube (1) en produit métallique profilé, en particulier destiné à être utilisé dans des échangeurs thermiques, un produit métallique profilé, et un procédé de production correspondant. Le tube (1) comprend une première paroi (2) et une seconde paroi (4) formant deux côtés opposés du tube, et plusieurs structures de renforcement reliant entre elles les deux parois (2, 4) et formant des passages longitudinaux (10) entre elles. Chaque structure de renforcement est formée par une crête longitudinale (6) sur la première paroi (2) en protubérance vers la seconde paroi (4) et une crête longitudinale (8) sur la seconde paroi (4) en protubérance vers la première paroi (2). Les crêtes (6, 8) se rejoignent sur leurs côtés.
