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 metal heat exchanger tube for the evaporation of liquids on the outside of the tube, comprising 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. According to the invention, 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.

摘要翻译： 本发明涉及一种用于在管外部蒸发液体的金属热交换器管，包括管轴，管壁和在管的外侧周向延伸的一体形成的肋。 肋具有肋脚，肋腹部和肋尖，其中肋脚基本上从管壁突出突出。 相应的凹槽位于沿轴向彼此相邻的每两个肋之间。 由肋的材料形成的至少第一，第二和第三侧向材料突起以这样的方式布置在肋侧面上的第一，第二和第三水平上，使得凹槽被大部分覆盖 材料预测。 根据本发明，第一，第二和第三侧向材料突起形成为在径向方向上与管壁不同的间隔开的水平面上。
