[0017] Example 1 (refer to) Figure 1-4 The winding device for the fabrication of stainless steel seamless U-shaped tubes for ultra-long bright heat exchangers includes a base 1, a hollow circular protrusion 2, and a winding column 4. The lower end of the base is driven to rotate by a drive device. A hollow circular protrusion is provided in the center of the upper end face of the base. A winding column is provided at the inner center of the hollow circular protrusion. One end of the winding column is wound on the outer side of the winding column, and the other end of the winding column is wound on the outer side of the hollow circular protrusion. The winding column spans across the upper end of the hollow circular protrusion.

[0018] The winding device for the stainless steel seamless U-shaped tube fabrication device for ultra-long bright heat exchangers has a vertically hollowed-out groove 5 on the side wall of the hollow circular protrusion. The other end 31 of the belt has a limiting part 32 that is larger than the other end of the belt. The other end of the belt is inserted into the vertically hollowed-out groove from top to bottom. The limiting part is located inside the side wall of the hollow circular protrusion. The thickness of the limiting part is greater than the vertically hollowed-out groove.
