Abstract

A heat transfer tube with a finned inner surface is divided into at least two zones (Z1 to Zm) in a peripheral direction. The fins extend at an angle of inclination alpha with respect to the longitudinal axis of the tube, are arranged in the individual zones (Z1 to Zm) in any desired periodic combination and sequence of at least two fin heights (H1 to Hn, H1>H2> . . . >Hn). Adjacent zones border thereby on one another so that the fin sequence is staggered for at least one fin in longitudinal direction of the tube. Modifications include the finned inner surface being divided into groups of zones, in which the angle of inclination of the fins is uniform, however, varies between adjacent groups.
