Abstract

The invention relates to a heat exchanger tube (1) having a tube longitudinal axis (A), a tube wall (2), an outer tube face (21) and an inner tube face (22), wherein axially parallel or helically circumferential continuous fins (3) are formed on the outer tube face (21) and/or inner tube face (22) which fins continuously run from the tube wall, and continuously extending primary grooves (4) are formed between respectively adjacent fins (3). According to the invention, the fins (3) along the fin profile are subdivided into periodically repeating fin sections (31) which are divided into a multiplicity of projections (6) with a projection height (h), wherein the projections (6) are formed between primary grooves (4) by making cuts into the fins (3) at a cutting depth transversely with respect to the fin profile to form fin segments and by raising the fin segments in a main orientation along the fin profile.
