Description

Technical Field

[0001] The utility model relates to the technical field of copper tube fin welding, in particular to a copper tube heating device used for hot-melt welding of copper tube fins. Background Art

[0002] As a common radiator, finned copper tubes are added with fins at the outer end of the copper tube to increase the heat dissipation effect. According to production needs, it is necessary to produce a finned copper tube. Figure 1 and attached Figure 2 A finned copper tube is shown, wherein the copper tube is a long square tube, and two long fins are respectively arranged at the upper and lower ends of the tube, the fins have the same width and length as the copper tube, and the copper tube and the upper and lower long fins are welded into shape;

[0003] During the welding process of the finned copper tube, the copper tube needs to be welded to two sets of fins. Usually, the two are manually welded by electric welding. Since the copper tube and the fin have a certain width, the staff cannot weld the inner wall when welding them, which makes it impossible to fully weld the copper tube and the fin, and the quality of the finned copper tube after welding is affected. Then, hot melt welding of the copper tube and the fin is selected. Hot melt welding requires heating of the copper tube, and the way to heat the copper tube is often to energize both ends of the copper tube. Since the copper tube will produce phase deformation during the heating process, the copper tube will affect the normal operation of the heating device when it produces phase deformation.
