We can customize Elliptical Finned Tube according to your drawings
Example:
oval rectangular finned tube, oval finned tube, oval circular finned tube, helical oval flat tube, oval H-shaped finned tube.The fins are typically made of materials like aluminum or copper and are spirally or helically wrapped around the base tube. The elliptical shape of the tube and the arrangement of the fins help to enhance heat transfer efficiency.
Elliptical Finned Tube is an elliptical seamless tube as the base tube, which uses aluminum fin strips or copper fin strips to spirally and tightly wrap around the outer surface of the base tube under tension.
Elliptical Finned Tube is an elliptical seamless tube as the base tube, which uses aluminum fin strips or copper fin strips to spirally and tightly wrap around the outer surface of the base tube under tension. Elliptical Finned Tube is a heat exchange element consisting of a base tube elliptical tube and outer fins.
Because Elliptical Finned Tube has superior performance than round finned tube, Elliptical Finned Tube is receiving attention, and Elliptical Finned Tube has been widely used in ethylene, oil refining and other industrial fields. Elliptical Finned Tube is used in heat exchange equipment as a high-efficiency heat exchange element. The flow resistance outside the tube is small and the heat exchange efficiency is high, which makes the heat exchange equipment tend to be compact, lightweight, efficient and miniaturized. Although much research has been done on them, there is still a lot of research work to be done.
Features of Elliptical Finned Tube
Compared with the round tube finned tube, the Elliptical Finned Tube is easier to achieve a compact arrangement, which reduces the overall volume of the entire heat exchanger, thereby reducing the footprint.
Due to the shape characteristics of the Elliptical Finned Tube, the air-side resistance is small, and the heat transfer coefficient between the fluids increases; the thermal resistance in the tube is relatively small, which increases the heat transfer of the fluid in the tube.
The heat transfer area of the Elliptical Finned Tube is larger than that of the circular tube of the same cross-sectional area, because the heat transfer periphery of the elliptical tube is relatively long under the same cross-sectional area.
Rectangular steel fins are the most commonly used in Elliptical Finned Tubes, which have high strength, and the base tube is not suitable for frost cracking in winter and has a long service life.
Since the Elliptical Finned Tube can be arranged more compactly, the front row tube has a greater impact on the rear row. The fin spacing of the rear row tube can be increased to reduce the flow resistance outside the tube, but the number of tube rows should not be too large.
