Abstract

A finned tube for heat exchanger or the like, having fins running circumferentially on the outside of the tube, the base of the fins extending essentially radially from the tube wall and the outer ends of the fins approaching outer ends of adjacent fins, characterized in that the Y-shaped fins run in the circumferential direction around the tube continuously, with the Y-configuration being continuous and uninterrupted around the tube circumference.
