A finned tube for heat exchangers comprises a plurality of sections adjoining to one another. The sections are of V-shape, define a central core, and are provided with arc-shaped wings. The sections are associated to one another by superimposing the wings of the adjoining section wings. The sections are connected by longitudinal welding. The finning is formed by a metal band applied on the outside of the tube. According to one embodiment, each section has a substantially T-shaped cross-section. The metal band may have a plurality of notches. |
