Abstract

Tubes à cannelures hélicoïdales pour échanges de chaleur et son procédé de fabrication. Il comporte un certain nombre de cannelures en spirale sur toute sa longueur. Il peut être obtenu en partant d'une bande plate d'un matériau de base dans laquelle sont pratiquées des cannelures longitudinales, par laminage, ou autrement, les creux des surfaces opposées étant, de préférence, séparés par une épaisseur du matériau de base. La bande est alors enroulée en hélice autour d'un axe et les bords en about sont fixés, par soudure ou autrement. Le mouvement tourbillonnaire causé dans les fluides en circulation par ces cannelures active les échanges de chaleur. Applicable notamment aux générateurs de vapeur et appareils de traitement.
