Elliptical fin tubeA heat exchange element composed of a base tube elliptical tube and outer fin. Common types include elliptical rectangularFinned tubeElliptical finned tubes, circular finned tubes, spiral elliptical flat tubes, elliptical H-shaped finned tubes, etc. Elliptical finned tubes, due to their superior performance over circular finned tubes, are gaining attention and are widely used in industrial fields such as ethylene and refining. As heat exchange elements, elliptical finned tubes are used in heat exchange equipment, featuring low flow resistance and high heat exchange efficiency, leading to compact, lightweight, and miniaturized heat exchange equipment. Although many research achievements have been made, there is still much research work to be carried out.

Elliptical finned tubes are used as heat exchange elements in heat exchange equipment. With low external flow resistance and high heat exchange efficiency, these tubes enable the heat exchange equipment to become more compact, lightweight, and miniaturized. Although many research achievements have been made on them, there is still much research work to be done.
