Abstract: 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.

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: The invention relates to a metal heat exchanger tube, comprising integral ribs formed on the outside of the tube. Said 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.
Abstract translation: 本发明涉及一种金属热交换器管，其包括形成在管外侧的整体肋。 所述肋具有肋基部，肋侧面和肋尖。 肋基部从管壁大致径向突出。 在肋之间形成通道，其中布置有彼此间隔开的通道附加结构。 附加结构将肋之间的通道分成段。 附加结构减小了两个肋之间的通道中的横截面面积，通过该横截面积，流动可能在局部至少60％，并且至少从而限制了在操作期间通道中的流体流动。
