G型镶嵌式翅片管使用注意事项

G型镶嵌式钉头管翅片管是一种新型高效换热元件。它是针对串片型和绕制型翅片做成的散热器的缺点,而改进采用高频焊接翅片管的一种高效散热元件,翅片管的本身是将带钢缠绕于钢管上,同时采用高频焊接工艺,把片焊牢在管上,保证了管与翅片的结合强度,具有换热效率高,散热面积大,使用寿命长,适应温度范围广,承受压力高等特点。本厂可以根据用户要求制作,直径从20至150mm各种规格、材质的G型镶嵌式翅片管。

G型镶嵌式翅片管其主要优点是:

  1、 生产效率高,可连续缠绕生产;

  2、 成本低,它依靠高频焊接本身的特性——集肤效应加热工件表面,达到焊牢的目的,焊接过程中不需添加任何填充金属材料;

  3、 由于高频电流仅在钢管浅表面通过,焊接热影响区小,因此设计计算时,不需考虑由此引起的壁厚附加量;工件焊后也不需要进行热处理;

  4、 焊接牢靠,能承受频繁开、停工而引起的热冲击波动。

 

G-type inlaid finned tube is a new type of high efficiency heat exchanger. In view of the shortcomings of the radiators made of serial and wound fins, it is an efficient heat dissipation element that improves the use of high-frequency welded finned tubes. The finned tubes themselves wind the strip steel on the steel pipes. At the same time, high-frequency welding technology is used to weld the fins firmly on the tubes, ensuring the bonding strength between the tubes and fins. It has the characteristics of high heat exchange efficiency, large heat dissipation area, long service life, wide temperature range and high pressure. Our factory can make G-shaped inlaid finned tubes of various specifications and materials with diameters from 20 to 150 mm according to user requirements.
The main advantages of G-type inlaid finned tube are:
1. High production efficiency, continuous winding production;
2. Low cost, it relies on the characteristics of high-frequency welding itself - skin effect to heat the surface of the workpiece, so as to achieve the purpose of welding firmly, and no filler metal materials need to be added in the welding process;
3. Because the high-frequency current only passes through the shallow surface of the steel pipe and the welding heat affected zone is small, the additional wall thickness caused by this need not be considered in the design calculation; The workpiece does not need heat treatment after welding;
4. The welding is firm and can withstand the thermal shock fluctuation caused by frequent startup and shutdown.
