摘要： This invention relates to a heat transfer surface (3) or tubular or plate-like bodies (4) having a microstructure (7) projecting out of the base surface (3a) and consisting of projections (6) which are galvanized onto the base surface (3) with a minimum height of 10 &mgr;m. The object of this invention is to create a heat transfer surface (3) of this type which is characterized by an increase in thermal efficiency of its heat transfer surfaces (3) with the smallest possible temperature differences and is suitable for both nucleate boiling and film condensation with a justifiable manufacturing expense. The object is achieved according to this invention by the fact that the base surface (3a) is covered entirely or partially with projections (6); these projections (6) are applied in the form of ordered microstructures (7) and they have a pin shape, extending with their longitudinal axis (6c) either at a right angle to the base surface (3a) or at an angle (&agr;) between 30° and 90°.

摘要： This invention relates to a pipe (1) having several internal ribs (2, 3, 4) having a spiral twist, where the ribs run with rotational symmetry with the longitudinal axis (5) of symmetry of the pipe (1). This invention creates a heat transfer pipe that will be characterized by a much better heat transfer in comparison with the previously known pipes having internal ribs, and to this end it guarantees not only an increase in the internal heat transfer surface area but also an effective cross-flow between the inside wall surface of the pipe and the core flow near the longitudinal axis of symmetry. To that end, the free ends (2c, 3c, 4c) of the internal ribs (2, 3, 4) are a distance (a) from the longitudinal axis (5) of symmetry of the pipe (1), which is in the range of 1:12 to 1:3 in relation to the inside diameter (d) of the pipe; and all the internal ribs (2, 3, 4) run in the same direction (arrow 6) and with the same spiral length (L) with a spiral twist to the longitudinal axis (5) of symmetry.
摘要翻译：本发明涉及一种具有多个具有螺旋扭转的内部肋（2,3,4）的管（1），其中所述肋与所述管（1）的对称纵向轴线（5）以旋转对称的方式延伸。与先前已知的具有内肋的管相比，形成了一种传热管，其特征在于具有更好的传热性能，并且为此，它不仅保证了内部传热表面积的增加，而且确保了有效的交叉流动在管道的内壁表面和靠近纵向对称轴线的芯流之间。为此，内部肋（2,3,4）的自由端（2c，3c，4c）与管（1）的对称的纵向轴线（5）的距离（a）是相对于管的内径（d）为1:12〜1:3的范围; 并且所有内部肋（2,3,4）沿相同的方向（箭头6）延伸并且以相同的螺旋长度（L）以对称的纵向轴线（5）螺旋扭转。
