Technical Field
[0001] This utility model relates to the field of spiral finned tube technology, and in particular to a spiral finned tube welding strip feeding connection assembly. Background Technology
[0002] Typically, heat exchangers that need to transfer heat are made to increase their surface area and improve their efficiency by adding highly thermally conductive metal fins. These metal fins are called fins.
[0003] To improve heat exchange efficiency, fins are usually added to the surface of the heat exchange tube to increase the outer (or inner) surface area of the heat exchange tube, thereby improving the heat exchange efficiency. The fins are usually welded to the outer circumference of the heat exchange tube in a spiral manner, and the heat exchange tube with spiral fins is called a spiral finned tube.
[0004] When welding spiral finned tubes, a tractor is needed to pull the heat exchange tube and rotate it around its own central axis so that the fins are welded to the surface of the heat exchange tube in a spiral shape. Since the length of a roll of finned material is limited, and a new roll of finned material needs to be replaced after one roll of finned material is unwound, the end of the previous roll of finned material needs to be welded and fixed to the beginning of the new roll of finned material. Without the assistance of professional connecting components, welding is not easy and the welding efficiency is low.
[0005] Therefore, it is necessary to improve the existing spiral finned tube welding strip feeding connection assembly. Utility Model Content
