Title

(EN) HEAT EXCHANGER TUBES

(FR) TUBES D'ÉCHANGEUR DE CHALEUR

Abstract

(EN) A method of forming a tube portion T for a heat exchanger HE. Two or more external supports (7) have part-cylindrical tube-facing portion. The method comprises dimpling a precursor tube portion to form dimples. The dimpling comprises the two or more external supports (converging, relative to each other, on the precursor tube portion to radially support a portion of the precursor tube portion via the part-cylindrical tube-facing portions to form a supported tube portion) and moving one or more tool portions 9 against, to inwardly deform, one or more dimple sites within and spaced from ends of the supported tube portion.

(FR) L'invention concerne un procédé de formation d'une partie de tube (T) pour un échangeur de chaleur (HE). Au moins deux supports externes (7) comportent une partie partiellement cylindrique faisant face au tube. Le procédé comprend l'emboutissage d'une partie d'un tube précurseur afin de former des empreintes. L'emboutissage comprend lesdits au moins deux supports externes (convergents les uns par rapport aux autres vers la partie de tube précurseur afin de supporter radialement une partie de celle-ci par l'intermédiaire des parties partiellement cylindriques faisant face au tube, de manière à former une partie tube supportée) et le déplacement d'une ou plusieurs parties outils (9) contre un ou plusieurs emplacements d'emboutissage situés à l'intérieur de la partie de tube supportée et espacés de ses extrémités, afin de déformer ces emplacements vers l'intérieur.
