结构设计特殊的H型翅片管适应能力强

双H型和单H型我们都可以统称为H型翅片管,作为加强和提升换热的元件被各大行业所应用,广泛的使用在工业的锅炉、电站的锅炉和窑炉等烟气系统的余热回收装置中,随着换热行业的迅速发展,H型翅片管的使用也越来越普遍,主要还是由于其自身的结构设计较为独特,整体的构造非常稳定且不易发生变形,传热的效率更高也是H型翅片管应用愈发广泛的主要原因。在结构上H型翅片管采用的是锯齿的独特设计,利用对冲的方式将翅片和钢管进行焊接,而焊接后翅片的接触形成较多的锯齿形,因此受热的面积才会更加的均匀,焊接的表面也较为牢固,焊角的整个表面非常圆滑,不会出现夹渣的气孔以及现象,在焊接的熔合率上可以达到98%以上的效果,更是为良好的传热系数提供了有利的保障。

Double H type and single H type can be collectively referred to as H type finned tubes, which are used in various industries as components to enhance and enhance heat exchange. They are widely used in waste heat recovery devices of industrial boilers, power station boilers, kilns and other flue gas systems. With the rapid development of the heat exchange industry, H type finned tubes are increasingly used, mainly because of their unique structural design, The overall structure is very stable and not easy to deform, and the higher heat transfer efficiency is also the main reason why H-shaped finned tubes are more widely used. In structure, H-shaped finned tubes adopt the unique design of serrations. The fins and steel pipes are welded by means of butt welding. After welding, the fins contact to form more serrations, so the heated area will be more uniform, the welded surface will be more solid, the entire surface of the weld corner is very smooth, without slag inclusion pores and phenomena, and the fusion rate of welding can reach more than 98%, It also provides a favorable guarantee for good heat transfer coefficient.

由于H型翅片管在布置上采用的是顺列的方式,钢管的表面空间会被翅片分割成若干个小区域,为烟气起到了均流的作用,如果和使用错列方式布置的光管,以及螺旋的翅片相比较的话,H型翅片管在钢构性能上更好,且不容易产生变形现象,不管是磨损或寿命都更长。在防腐的性能方面H型翅片管同样占据优势,不仅是耐更多介质的腐蚀,适应环境的能力非常强,但是某些产品制造后没有进行复合材质的处理,只是在铝制的产品中添加上钢管即可,因此在使用时防腐的性能会稍低,所以还是建议大家选购正规的品牌,相应的在质保上也更有保障。其次,铜铝复合材质的暖气片结构瘦高扁片,虽然可以节省大量的空间,但因为产品的特殊性需要水压较大,供暖锅炉是无法满足要求的,那么这类翅片管的应用会比较受限制。

 

As the arrangement of H-shaped finned tubes is in line, the surface space of the steel tube will be divided into several small areas by fins, which plays a role in equalizing the flow of flue gas. If compared with smooth tubes arranged in staggered way and spiral fins, H-shaped finned tubes have better steel structure performance, are not easy to produce deformation, and have longer wear and life. In terms of anti-corrosion performance, H-shaped finned tubes also occupy an advantage. They are not only resistant to more media corrosion, but also have a strong ability to adapt to the environment. However, some products have not been treated with composite materials after manufacturing, and only steel pipes can be added to aluminum products. Therefore, the anti-corrosion performance will be slightly lower when used. Therefore, it is recommended that you choose a formal brand, and the corresponding quality assurance will be more guaranteed. Secondly, although the copper aluminum composite radiator structure is thin and flat, it can save a lot of space, but because of the particularity of the product, the water pressure is large, and the heating boiler cannot meet the requirements, then the application of this type of finned tube will be limited.
