Abstract (en)
The invention relates to a heat exchanger tube comprising a metal strip rolled and welded onto itself, which includes a part extending inside the tube to form a perturbation device capable of generating turbulence on a fluid flowing in the tube. According to the invention, the strip includes two margin parts (18) extending on either side of a central part (20), at least one of the margin parts (18) forming a perturbation device, and each of the margin parts (18) being folded along a folding edge (26), towards the central part (20), the two folding edges (26) being brought together by rolling up the central part and the margin parts of the strip which are welded onto each other. Application in particular to heat exchangers for motor vehicles. <IMAGE>
