Heat exchanger is a very good energy-saving equipment, which can reuse the energy that would have been wasted. Fin-tube heat exchanger is a member of the heat exchanger family. Today, the fin-tube manufacturer Xiaobian will introduce some working principles and characteristics of fin-tube heat exchanger for you, so as to facilitate your understanding of fin-tube heat exchanger. The film tube heat exchanger has a better understanding.
The principle of finned tube heat exchanger -- characteristics of finned tube heat exchanger
1. Heat transfer efficiency is high because the fin disturbance to the fluid causes the boundary layer to break up continuously, so it has a larger heat transfer coefficient. At the same time, because the partition and fin are very thin and have high thermal conductivity, the fin-tube heat exchanger can achieve high efficiency.
2. Compact finned-tube heat exchanger has an extended secondary surface, so its specific surface area can reach 1000_/m3.
3.輕巧 原因為緊湊且多為鋁合金制造，現在鋼制，銅制，復合材料等的也已經批量生產 。
3. The reason for lightness is compact and mostly made of aluminium alloy. Now steel, copper and composite materials have been produced in batches.
4. The finned-tube heat exchanger with strong adaptability can be applied to heat transfer between gas-gas, gas-liquid, liquid-liquid and various fluids, as well as phase change heat transfer with collective change. Through the arrangement and combination of the runners, it can adapt to different heat transfer conditions, such as countercurrent, cross flow, multi-stream, multi-pass flow and so on. Through the combination of units in series, parallel connection and series parallel connection, the heat exchange needs of large equipment can be satisfied. Industry can be stereotyped and mass produced to reduce costs and expand interchangeability through building blocks.
5. the manufacturing process is strict and the process is complicated. It is easy to plug, not corrosion-resistant and difficult to clean and repair, so it can only be used in situations where heat transfer media are clean, non-corrosive, not easy to scale, not easy to deposit and not easy to plug.
The above is to introduce some of the working principles and characteristics of finned tube heat exchanger, I hope you can refer to understand, when we need to buy the use of finned tube heat exchanger in the future, I believe that it can certainly bring us a very good use effect, save more energy resources.
