Elliptical fin tube is a heat exchange element composed of a base tube and an outer fin. Common ones include elliptical rectangular fin tube, elliptical elliptical fin tube, elliptical circular fin tube, spiral elliptical flat tube, elliptical H-shaped fin tube, etc.

Elliptical fin tubes are gaining attention due to their superior performance over circular fin tubes. Elliptical fin tubes have been widely used in industrial fields such as ethylene and oil refining.

Elliptical fin tubes are used in heat exchange equipment as high-efficiency heat exchange elements. The outer flow resistance of the tube is small and the heat exchange efficiency is high, making the heat exchange equipment compact, lightweight, efficient and miniaturized. Although many results have been achieved in their research, there is still a lot of research work to be done.
