翅片管从结构型式上翅片管可分为纵向和径向两种基本类型,其他型式均为这两类的开展和变形,例如大螺旋角翅片挨近纵向,小螺旋角翅片挨近径向翅片的形状有圆形、矩形和针形。此外,翅片可设置在管外,称外翅片管;也可设置在管内,称内翅片管或内外兼有。翅片管在进行使用有很多的种类,这样的产品在市场上也不断的涌现其新的品种,翅片管在干燥设备的运行中的作用是给热空气加热物料,这样就使得物料中的水分会蒸发,然后在进行循环干燥的时候,因为存在着较高的温度的空气已经接近了饱和状态,所以翅片管中高温高湿的空气已经不能将物料中的水分带走,所以材料中的水分开始停止蒸发,继续操作会对其产生不利的影响,需要排除这种做法。

The finned tube can be divided into two basic types: longitudinal and radial. The other types are the development and deformation of these two types. For example, the large spiral angle finned tube is close to the longitudinal direction, and the small spiral angle finned tube is close to the radial fin. The shape of the fin is round, rectangular and needle shaped. In addition, the fins can be arranged outside the tube, which is called the outer finned tube; it can also be set in the tube, called the inner finned tube or both.


翅片管按照其制作工艺分类

Finned tubes are classified according to their manufacturing process

翅片管制作工艺可将翅片管分类为全体翅片管、高频焊翅片管、机械衔接翅片管以及焊接翅片管,一般情况下其全体的翅片管在进行制作的过程中主要是由铸造、机械加工或轧制而成,翅片与管子为一全体。焊接翅片管,运用钎焊或惰性气体维护焊等工艺制作。现代焊接技能可使不同资料的翅片衔接在一起,并能将翅片管制作得简略、经济,具有较好的传热及机械性能,已被广泛应用。由于焊缝中残渣不利于传热,甚至会引起开裂,因此在生产这类翅片管时必须确保焊接工艺质量。

Finned tube manufacturing process can be divided into all finned tubes, high frequency welded finned tubes, mechanically connected finned tubes and welded finned tubes. Generally speaking, all finned tubes are mainly made ofCast, machined or rolled, with fins and tubes as a whole. Welding fin tube, using brazing or inert gas maintenance welding and other processes. Modern welding technology can connect the fins of different materials together, and make the finned tube simple and economical. It has good heat transfer and mechanical properties, and has been widely used. Because the residue in the weld is not conducive to heat transfer and even cause cracking, the welding process quality must be ensured in the production of this kind of finned tube.

高频焊翅片管主要是利用其高频发生器发生的频电感应,这样就可以使得管子外表和翅片接触处发生高温,在10μm左右的深度范围内使两者溶化,再加压使翅片与管子连为一体。无焊剂,也无焊料,制作简略,生产率高,传热及机械性能好。这是为理想的一类翅片管,正为广大用户认识和采用。

High frequency welding of finned tube is mainly based on the frequency electric induction generated by its high-frequency generator, which can make the surface of the tube and the fin contact place produce high temperature, dissolve the two in the depth of about 10 μ m, and then pressurize to connect the fin and the tube. No flux, no solder, simple production, high productivity, good heat transfer and mechanical properties. This is an ideal type of finned tube, which is being recognized and adopted by the majority of users.

翅片管通常情况下会有其镶嵌式、套片式、绕片式、或串片式等三种类型。绕片式翅片管制作简略,把金属带用机械或焊接方法周定于管子一端,借管子转动力矩将金属带紧紧地缠绕于管外壁,另一端固定即成绕片式翅片管。绕片的资料可以是铜带、钢带或者铝带。

There are three types of finned tubes, such as inlaid, jacketed, wound, or string. The metal belt is fixed around one end of the pipe by mechanical or welding method. The metal belt is tightly wound on the outer wall of the tube by the rotating moment of the pipe, and the other end is fixed to form the wound fin tube. The data of winding can be copper strip, steel strip or aluminum strip.

如果是材料的含水量较高的话,就会在很短的时间内就会造成外界热空气的较为饱和的状态,如果一般都采用的全新风进行干燥,就是指翅片管的翅片在进行加热之后,把达到温度的热空气在送进干燥器里,同时再→另外一段排出,在隧道式烘道内,热空气的流向与物料的流量相逆流。
