An elliptical finned tube is a heat exchange of a base tube, elliptical tube, and external fins. The common ones are elliptical rectangular finned tubes, elliptical shape finned tubes, elliptical, circular finned tubes, spiral, elliptical flat tubes, elliptical H-shaped finned tubes, etc.
Elliptical finned tubes are being paid more attention to because of their superior performance than round finned tubes. Elliptical finned tubes have been widely used in ethylene, oil refining, and other industrial fields. Elliptical finned tubes are used in heat exchange equipment as efficient heat exchange components. The small flow resistance outside the tube and high heat exchange efficiency make the heat exchange equipment compact, light, efficient, and miniaturized. Although many achievements have been made in their research, much research is still to be carried out.
♦ The elliptical finned tube comprises an elliptical base tube and an outer fin. The common ones are elliptical rectangular finned tubes, elliptical finned tubes, elliptical, circular finned tubes, spiral, elliptical flat tubes, elliptical H-shaped finned tubes, etc. Elliptical finned tubes are being paid more attention to because of their superior performance than round finned tubes. Elliptical finned tubes have been widely used in ethylene, oil refining, and other industrial fields.♦ When calculating the fin efficiency of an elliptical tube fin heat exchanger, people often equate elliptical finned tubes with round finned tubes and calculate and analyze according to round finned tubes. There are two methods for selecting equivalent round pipe. One is to make the cross-sectional area of the equivalent round pipe equal to that of the elliptical pipe, and the other is to make the circumference of the equivalent round pipe equal that of the elliptical pipe.
