    摘要: The invention relates to a method for manufacturing finned tubes made of metal, in particular heat exchanger tubes, where at least one continuous strip forming the fins is fed tangentially to a tubular body set into rotational motion, and wound onto it, the side of the strip facing the tubular body is connected to the tube surface by means of a welding device and using a filler material, and the strip to be wound is guided between guide discs just behind the welding area, said discs reaching close up to the tube surface and the welding point. To increase the service life of the guide discs, the guide discs are cooled, specifically with cooling water to which roughly 10% by volume of a welding release agent are added.

    摘要: A method and equipment for making a needle-fin tube having needle-like external fin parts, and internal fin structure formed by a spiraled spring wire which expands to clamp again the tube in the needle-fin tubes. The wire used to form the internal fin is wound along and around a bar which is moved and rotated along a straight line. The bar is moved inside the needle-fin tube from its one end to the other and the wire is released from the bar to attach to the internal surface of the needle-fin tube under spring force.

    摘要: An internal grooved tube according to the present invention comprises a large number of fine spiral grooves on the inside surface in parallel arrangement, wherein the grooves are formed to assure that the ratio of a groove width in the tube axial direction to a groove height is in the range of 1 to 2. A lead angle null of the grooves to the tube axis is preferably limited to 26 to 35 degrees. A method of manufacturing an internal grooved tube according to the present invention comprises the steps of inserting a grooved plug into a blank tube rotatably, and then pressing the blank tube against the outside surface of the grooved tube with several balls revolving both around the circumference of the blank tube and on its axis in a location of the grooved plug inserted, while drawing out the blank tube longitudinally in one direction, wherein the number of balls is limited to 2 to 3.

    摘要: The invention concerns a process for manufacturing ribbed tubes, wherein a stainless steel tube is provided with ribs by helicoidally winding a copper strip around it, and a ribbed tube thus manufactured. In joining the tube and rib, the unmelted copper strip is set on the tube surface edgewise into a melted area produced by a laser beam exclusively on the tube surface, thereby bonding the strip onto the tube by the solidification of the melted tube material. In this manner ribbed tubes can be provided, featuring an internal tube made of corrosion-resistant stainless steel and a helicoidal rib made of copper for increasing the heat exchange surface of the tube, which is distinguished by high thermal conductivity.
