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.
