Abstract

Tube à ailettes dont la paroi extérieure porte des ailettes en forme de T qui entourent circonférentiellement le tube, la base des ailettes partant radialement de la paroi du tube et les extrémités extérieures des ailettes étant dirigées vers les extrémités extérieures des ailettes adjacentes. L'appareil qui permet de fabriquer ce tube se compose essentiellement d'un outil de roulage 7 comportant un certain nombre de disques de roulage 8, et d'un outil de lissage 11 comportant une surface oblique 12, les deux outils n'étant pas concentriques l'un à l'autre. Application aux échangeurs de chaleur.Finned tube, the outer wall of which carries T-shaped fins which circumferentially surround the tube, the base of the fins extending radially from the wall of the tube and the outer ends of the fins being directed towards the outer ends of the adjacent fins. The apparatus which makes it possible to manufacture this tube consists essentially of a rolling tool 7 comprising a certain number of rolling discs 8, and of a smoothing tool 11 comprising an oblique surface 12, the two tools not being concentric to each other. Application to heat exchangers.
