摘要： A metal heat exchanger tube has integral ribs formed on the outside of the tube. The ribs have a rib base, rib flanks, and a rib tip. The rib base protrudes substantially radially from the tube wall. A channel is formed between the ribs, in which channel additional structures spaced apart from each other are arranged. The additional structures divide the channel between the ribs into segments. The additional structures reduce the cross-sectional area in the channel between two ribs through which flow is possible by at least 60% locally and, at least thereby, limit a fluid flow in the channel during operation.

摘要： 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.

摘要： 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.

摘要： The invention relates to a heat exchanger tube having a tube longitudinal axis, wherein fins extend continuously from the tube wall on the tube outer face and/or the tube inner face, or extend axially parallel thereto or in the form of a helix. Continuously extending primary grooves are formed between adjacent fins, said fins have at least one structured area on the tube outer face and/or tube inner face, and the structured area has a plurality of projections of a projection height projecting from the surface, the projections being separated by notches. According to the invention, a plurality of projections are deformed relative one another in pairs to such an extent that cavities are formed between adjacent projections. Furthermore, according to the invention, a plurality of projections are deformed in the direction of the tube wall such that cavities are formed between a respective projection and the tube wall.

摘要： The invention relates to heat exchanger tube having a longitudinal tube axis; axially parallel or helically circumferential continuous fins are formed from the tube wall on the outer tube face and/or inner tube face, and continuous primary grooves are formed between adjacent fins; the fins have at least one structured zone on the outer tube face and/or inner tube face, said structured zone being provided with a plurality of projections which project from the surface an have a height such that the projections are separated by notches. According to the invention, the projections are arranged in groups which are periodically repeated along the extension of the fin. Furthermore, at least two notches between the projections within the group have a varying notch depth in a fin.

摘要： 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.
