Abstract

Turbulateur pour tube d'échangeur de chaleur. Il comprend une bande métallique qui, sur une partie au moins de sa longueur, à l'une de ses extrémités, est galbée ou profilée par au moins un pli longitudinal et dont au moins une de ses extrémités extérieure au tube est aplatie, lui conférant une largeur accrue empêchant l'entraînement du turbulateur à l'intérieur du tube. Application notamment à un radiateur de véhicule automobile.Turbulator for heat exchanger tube. It comprises a metal strip which, over at least part of its length, at one of its ends, is curved or profiled by at least one longitudinal fold and of which at least one of its ends outside the tube is flattened, giving it an increased width preventing the entrainment of the turbulator inside the tube. Application in particular to a motor vehicle radiator.
