Abstract: The invention relates to a finned tube (1), a process for its manufacture and a device for performing the process. The process involves at least one endless strip (4), forming the fins, being wrapped around a rotating tube body (2) in roughly helical fashion and the narrow side of the strip (4) facing the tube body (2) being joined to the tube surface by means of a welding device (7). In order to be able to work with little financial outlay and in an energy-saving manner, and to create a product where the entire width of the base of the fin is optimally joined to the tube surface and the joint area displays good thermal conduction, the working end of the welding device (7) is inserted into the free wedge-shaped space between the tube surface (3) and the strip (4) where, with the aid of the welding device (7) a welding bead (11) is applied, running exactly in the area of the joint between the strip (4) and the tube surface (3), to the tube surface (3) using a filler, before the narrow edge of the strip (4) to be joined makes contact. The narrow edge of the strip (4) to be joined is subsequently pressed into the welding bead (11) while it is still liquid. (FIG. 1)

Abstract: This invention relates to apparatus for facilitating the construction of a heat exchanger, such as a condenser or evaporator employed in an air conditioning system, wherein exchanger tubes extending through a plate fin assembly are joined together by means of return bend connections or the like. The ends of the tube are provided with an oval shaped bell in which are telescoped the return bends. Diametrically opposed nibs are formed on the outer surface of the return bend connectors near the distal end thereof. The outside diameter over the nibs is slightly larger than the minor inside diameter of the oval bell. The nibs are inserted into the bell aligned along the minor diameter of the opening. The nibs are thus caused to ride in engagement against the wall of the bell to frictionally support the connector in assembly. The joint is then immersed in a molten solder bath whereby solder flows freely into the joint region along the major axis to create a highly reliable joint.

Abstract: A metal-made honeycomb carrier body is provided for carrying thereon an exhaust gas cleaning catalyst. The carrier body has been formed by superposing a planar metal band made of a metal sheet and a corrugated band made from another metal sheet one over the other in a contiguous relation and defines a number of network-patterned gas flow passages along a central axis thereof. At one of opposite axial ends of the honeycomb carrier body, one of the planar band and the corrugated band extends outwardly relative to the other band.

Abstract: 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.

Abstract: A process of attachment of at least one rib on a pipe with a thin wall which comprises cutting a hole in the rib that corresponds closely to the outer diameter of the pipe; locating the rib on the outer surface of the pipe; pressurizing the interior of the pipe with a pressure sufficient to force the outer surface of the pipe into close relationship with the inner contour of the rib during or shortly before reaching the soldering temperature; attaching the rib to the pipe by soldering; and selecting the materials for the rib and pipe so that the linear thermal expansion coefficients allow a smaller gap between the pipe and the rib during soldering than when the pipe and rib are at room temperature.
