Abstract: A heat exchanger tube with a tube axis, a tube wall and with ribs extending around on the tube outer side. The ribs have a rib foot, rib flanks and a rib tip, wherein the rib foot projects substantially radially from the tube wall. The rib flanks are provided with additional structural elements which are arranged laterally on the rib flank. First material projections, which extend substantially in the axial and radial direction, adjoin second material projections which extend substantially in the axial and circumferential direction of the tube, wherein the first and second material projections have a common boundary line. The axial extent of the first material projections along this boundary line is less than the axial extent of the second material projections.

Abstract: A metal heat exchanger tube for the evaporation of liquids on the outside of the tube, having a tube axis, a tube wall, and integrally formed ribs that run circumferentially on the outside of the tube. The ribs have a rib foot, rib flanks, and a rib tip, wherein the rib foot projects substantially radially from the tube wall. A respective groove is located between every two ribs that are adjacent to one another in the axial direction. At least first, second, and third lateral material projections, which are formed from the material of the ribs, are arranged on a first, second, and third level on the rib flanks in such a way that the grooves are largely covered by all of the material projections. The first, second, and third lateral material projections are formed on levels that are in each case differently spaced apart from the tube wall in the radial direction.

Abstract: A heat exchanger tube with a tube axis, a tube wall, a tube outside and a tube inside. Continuously running, axially parallel or helically circling inner ribs are formed out of the tube wall on the tube inside, each inner rib having two rib flanks and a rib tip. A continuously extending groove is formed between adjacent inner ribs. The rib tip has at regular intervals recurring elevations which have an essentially frustopyramidal form. The inner ribs are raised in the radial direction on the contour line which is defined by the transitional edge of a rib flank to the rib tip and protuberances advancing out of the rib flank are formed in this region. Furthermore, the invention relates to a method for producing a heat exchanger tube.
