Abstract

Improvements made to finned tubes, intended primarily for heat exchangers, having fins squeezed in a single operation using an extrusion machine and having a continuous coil shape protruding from the tube wall, the fins forming a lower angle at 90º to the tube surface, the improvements characterized in that diametrically opposed segments of the fins bend at least substantially parallel to the tube axis.
