Abstract (en)

The tube has a closed contour outer envelop (1) formed by a folded sheared strip and an insert (7) formed by another folded sheared strip housed in the envelope and connected to the envelope for delimiting channels (21,26). The insert has localized depressions (31) distributed on a length and on a width of the latter shear strip. An independent claim is also included for a method for fabricating a flat tube with multiple channels for circulating fluid inside a heat exchanger.
