    • A heat exchanger element has a metal tube with fins disposed radially and in rows, to increase the heat exchange surface. The improvement of the invention is that the fins are of elliptical cross section and are arranged in rows which are equally spaced, the major axes of the respective cross sections of the fins in a row being parallel, and being parallel to or at 90.degree. or at 45.degree. to the tube axis, each fin in a row being staggered with respect to the corresponding fins of the adjoining rows. For welding such fins to the tube, there is used a hollow electrode having its inner cavity of substantially cross-like shape and corresponding to the combined outline of two fins having the major axes of their cross section inclined at 90.degree..
    • 热交换器元件具有金属管,翅片配置成径向排列,以增加热交换面。 本发明的改进在于翅片是椭圆形的横截面并且排列成等距间隔的排列,翅片的相应横截面的长轴线是平行的,并且平行于或在90°或 在与管轴成45°的位置处,每排翅片相邻于相邻排的相应翅片成一行错开。 为了将这种翅片焊接到管上,使用具有大致十字形形状的内腔的中空电极,并且与其横截面的主轴倾斜90°的两个散热片的组合轮廓相对应。
