摘要： An internally-grooved heat exchanger tube according to the present invention is structured such that the internal surface is divided into a plurality of continuous areas (W1, W2) parallel to the axial direction (L) of the tube, a large number of fins (10, 11) different in at least one selected among lead angle (&thgr;, &thgr;′) to the axial direction (L) of the tube, fin vertical angle (&agr;, &agr;′) and fin pitch (p, p′) are formed in the adjacent areas (W1, W2), and a boundary portion (a) between the adjacent areas (W1, W2) is formed in the state of meandering to the axial direction (L) of the tube. A metal strip machining roll for an internally-grooved heat exchanger tube according to the present invention is structured such that a plurality of roll pieces (2a, 2b) each having a large number of grooves (20, 21) on each outer surface are combined together in layers parallel to the axial direction, and a contact surface (c) of one roll piece (2a) with its adjacent roll piece (2b) forms an inclined surface.
摘要翻译：根据本发明的内槽式热交换器管被构造成使得内表面被分成与管的轴向（L）平行的多个连续区域（W1，W2），大量翅片形成从管角度（θ，θ'）到管轴方向（L）中选择的至少一个不同的翅片垂直角（α，α'）和翅片间距（p，p'）在相邻区域（W1，W2）和相邻区域（W1，W2）之间的边界部分（a）处于与管的轴向（L）相对的状态下形成。根据本发明的内槽式热交换器管被构造成使得在每个外表面上具有大量凹槽（20,21）的多个辊片（2a，2b）被组合在一起，其平行于形成一个辊片（2a）与其相邻的辊片（2b）的接触表面（c）一个倾斜的表面。
