The heat exchanger fin to tube joint is a T joint configuration and from the advantageous characteristics of laser welding previously described in Chapter 2 and reference to Fig. 2.4, one no doubt has already concluded that laser welding is ideally suited to this application. This particular advantage has been grasped for some time by KM
A fin tube is a tube that has small fins around the outside surface. These fins act as a filter and a mechanism to transfer heat from the material inside the tube to the outside space or vice versa. Fin tubes are used in applications that require a transfer of heat from a hot fluid to a colder fluid through the tube's wall.
The use of laser achieves high power density during welding which brings further specific benefits for the welded parts. Corrofin ® Finned Tubes are manufactured from copper materials by spiral winding the tubes with a band material and simultaneously soldering with tin solder. This achieves a good heat conducting joint between the tube and
