Copper Elliptical Finned Tube For Air Cooler

Elliptical Finned Tube Product Description:

Elliptical Fin Tube is manufactured by attaching a rectangular fin to a oval tube to significantly increase the heat transfer surface area. Elliptical finned tube has better air flow characteristics than conventional circular finned tube, it is considered as alternatives to circular solid finned tubes in Finned Tube Heat Exchanger field. In recent years, it becomes more and more popular in relevant Heat Exchanger field.

Oval finned tube is the cooling element of direct air cooler tube bundle. Because of the particularity of direct air cooler using environment, so it is necessary to have good anti corrosive processing on the surface of air cooler. In order to improve the service life of air cooler, hot dip zinc is used on the surface of Elliptic finned tube anti-corrosion. The quality requirements of Elliptic finned tube hot-dip zinc, not only contains the general requirements of hot-dip zinc parts leaching zinc quality, but also contains the Oval finned tube as the special requirements of cooling element leaching zinc quality. The characteristics of hot-dip zinc coating is that the protective effect on the surface of the substrate of hot dip galvanized steel is much better than a paint or plastic layer. During hot dip zinc, zinc and iron- steel has spread to produce a metallic compound layer which is called layer alloy. Alloy layer has multilayer structures, and the chemical compositions of which are Fe3Zn10 or Fe5Zn21, FeZn7, FeZn13, and etc. Alloy layer and steel as well as alloy and pure zinc layer is called metallurgical combination.

Elliptical Finned Tube(Oval Tube Aluminum) Manufacturing Process:

An oval seamless tube is used as the base tube, and the finned tube is spirally wound with aluminum fin tape or copper fin tape under tension and tightly wound on the outer surface of the base tube.

Elliptical Finned Tube(Oval Steel Tubing) Advantages:

The reflux zone and windward area is much smaller, reduce the hydromechanics on the air side, then reduce the energy consumption.

Inside the heat exchanger equipment, oval tube bundle is more compact than circular tube bundle, so the heat exchanger has smaller volume and is with lower cost.

The fins are not sensitive to typical mechanical loads, for example hailstorm or walk on the bundles.

The rectangular fins are with high strength, protecting the base tube from fracture in winter, prolonging the tube life-span.
