Features of Elliptical Finned Tube
(1) 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.
(2) 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.
(3) 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.
(4) 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.
(5) 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.
Application of Elliptical Finned Tube
Application: The convection chamber of the heating furnace in the petrochemical industry is used in the Elliptical Finned Tube
, which can increase the heat transfer coefficient on the gas side, and the area of the elliptical tube is 2 to 3 times that of the straight tube. Due to the application of Elliptical Finned Tube, in the design of this case, the same radiation intensity can get the same thermal intensity.
It uses winding technology, ranging from stable, segmented combination and firm, to surface galvanized and nickel-based brazing, depending on the application. has a high heat transfer efficiency, while the wind side has a small
Compared with the section of the circular tube, the heat transfer coefficient can be increased by 25%, and the air resistance can be reduced by 15%-25%.
