Description

Technical Field

[0001] The utility model belongs to the technical field of fin tube forming devices, in particular to a forming device for fin tubes by winding elliptical steel tubes with a cam drive at high speed. Background Art

[0002] Elliptical fin tube is a heat exchange element composed of base tube elliptical tube and outer fin. Compared with circular fin tube, elliptical fin tube has higher heat dissipation efficiency. When hot air or cold air flows through elliptical fin tube, elliptical fin tube has smaller wind resistance due to different shape, and air flows more smoothly. At the same time, the area of ​​fin tube directly contacted by hot air or cold air is larger, and has a larger heat transfer area.

[0003] In industry, compared with round fin tubes, elliptical fin tubes are gaining attention due to their superior performance. Elliptical fin tubes have been widely used in ethylene, oil refining and other industrial fields. Elliptical fin tubes are used in heat exchange equipment as high-efficiency heat exchange elements.
