Product Description
Height Fin Tube Radiator For Heat Exchanger System, The high-fin tube is used to advantage when gases are to be heated or cooled or when a process stream is to be air-cooled. High-fin tubes come in a wide variety of fin heights, thickness, and spacings, giving values of Ao/Ai up to 25. For corrosion protection, a mechanically bonded liner tube may be used inside the finned tube. The liner can be made of corrosion-resistant alloy, while the outer tube and fins are made of a high conductivity metal such as copper or aluminum to improve heat transfer.
One major application of high-finned tubes is in air-cooled heat exchangers. Atmospheric air, like all low pressure gases, gives a very low heat transfer coefficient at normal velocities. By contrast, the tube-side fluid, usually a liquid to be sensibly cooled or a vapor to be condensed may have a coefficient up to 100 times higher, or even more. Therefore, high-finned tubes are used in these exchangers to reduce to overall size of exchanger required.

Selection of Tube Spacing and Slice Distance

Usually, the fin-Tube Heat Exchanger spacing and height are mainly affected by the wing-to-wing ratio, fineness ratio and the tube inside and outside the media membrane heat transfer coefficient has a great relationship. If the tube inside and outside the membrane heat transfer coefficient of difference, should select the wing than the relatively large fin tubes, such as steam heating the air. When there is phase change in one side of the medium, the difference in heat transfer coefficient will be larger, such as the exchange of hot and cold air, when the hot air below the dew point, you can use finned tube heat exchanger. In the absence of phase change of air and air heat transfer, or water and water heat exchange, usually more suitable for bare pipe. Of course, you can also use low-fin tube, because at this time belongs to the weak heat transfer coefficient, to strengthen one side of which have some effect. However, the role of the wing is too large is not obvious, the best internal and external contact area of the tube at the same time to strengthen, you can use threaded pipe or groove tube.

Fins from the main consideration is fouling, dust, easy to clean and other factors, at the same time to be strictly in line with equipment requirements such as pressure drop. Arrangement, the pipe and the distance between the tube is not easy to too large, generally> 1mm or more for the cloth can be. In the heat transfer process, the air flow through the finned tube heat exchanger, the main is the two sides of the fin surface to participate in heat transfer. The middle part of the two fin tubes has only a small amount of radiation heat transfer, the heat transfer effect is not obvious. This part because no fin, no resistance, easy to penetrate the air. During the process of air heating, the cold air without heat exchange will neutralize the heated air passing through from the middle of the fin, but reduce the effect of heat exchange. Compared with the foreign finned tube heat exchanger, The spacing is only 0.5mm larger than the outer diameter of the fin, showing the importance of the tube spacing when arranging the finned tubes.
