Zhengde Elliptical finned tube is a heat exchange element composed of base tube elliptical tube and external fin. Common ones include elliptical rectangular finned tube, elliptical oval finned tube, elliptical circular finned tube, spiral elliptical flat tube, elliptical H-shaped finned tube, etc. Elliptical finned tube is gaining attention due to its superior performance compared with circular finned tube. Elliptical finned tube has been widely used in industrial fields such as ethylene and oil refining. Elliptical finned tube is used in heat exchange equipment as a high-efficiency heat exchange element. The outer flow resistance of the tube is small and the heat exchange efficiency is high, which makes the heat exchange equipment compact, lightweight, efficient and miniaturized.
