    双金属翅片管具有单金属不可比拟的优点

    双金属翅片管由基管(如钢管,铜管)和铝管在翅片管机上冷轧复合成型,也称钢(铜)铝复合翅片管或轧片管。它克服了铝和其它金属不能焊接的缺点,利用基管的耐压性和铝的高效传热性、可塑性,突出了两种材料在工艺上的特点。具有其它类型翅片管不可比拟的优点。
    The bimetal finned tube is formed by cold rolling of the base tube (such as steel tube, copper tube) and aluminum tube on the finned tube machine, also known as steel (copper) aluminum composite finned tube or rolled tube. It overcomes the disadvantage that aluminum and other metals can not be welded, and highlights the technological characteristics of the two materials by making use of the pressure resistance of the base tube and the high efficiency heat transfer and plasticity of aluminum. It has the unparalleled advantages of other types of finned tubes.
    重量轻:铝的比重是常用有色金属和黑色金属中最小的,轻金属的翅片材质决定了用它制造的热交换器具有重量轻的特点。
    Lightweight: Aluminum is the smallest proportion of common non-ferrous and ferrous metals, light metal fin material determines the use of its heat exchanger with light weight characteristics.
    传热性能高:铝的导热性约211.9W/m•K,较银铜而言成本更低,性价比更高。导热性能好的物体,往往吸热快,散热也快。
    High heat transfer performance: the thermal conductivity of aluminum is about 211.9W/m. K, lower cost and higher cost performance than silver and copper. Objects with good thermal conductivity tend to absorb heat quickly and dissipate heat quickly.
    空气阻力小:双金属翅片管加工成型后翅片表面光滑无褶皱。空气可以从翅片间距内轻易穿透。
    The air resistance is small: the finned surface of the bimetal finned tube is smooth without wrinkles. Air can be easily penetrated from the fin spacing.
    接触热阻低:实践证明,双金属翅片管在210度以下的工作环境中接触热阻几乎为零。低接触热阻是高效传热的性能保证。
    Low contact thermal resistance: Practice has proved that the contact thermal resistance of bimetal finned tube in the working environment below 210 degrees is almost zero. Low contact thermal resistance is the guarantee of high efficiency heat transfer.
    散热面积大:双金属翅片管翅化比最大可达22.7。单位散热面积远大于常规绕片散热管。
    The heat dissipation area is large: the fin to tube ratio of bimetallic fins can reach up to 22.7. The heat dissipation area of the unit is much larger than that of the conventional winding tube.
    使用寿命长:双金属翅片管在加工的过程中,基管和铝翅片紧密的复合成一体。并在基管表面形成0.5mm厚的一层包覆层,保护基管不与外界环境空气接触,可提高使用寿命。
    Long service life: bimetal finned tube in the process of processing, the base tube and aluminum fin close composite integration. A 0.5mm-thick cladding layer is formed on the surface of the base pipe to protect the base pipe from contact with ambient air, which can improve the service life.
    双金属翅片管还具有不易结尘,不易结垢。易清洗和排除表面积水,对温度的特变有良好的抗力,能长期保持良好的传热性能等特点。
    Bimetallic finned tube is also difficult to deposit and is not easy to scale. It is easy to clean and remove surface water, has good resistance to temperature changes, and can maintain good heat transfer performance for a long time.辛苦整理.转载请注明http://www.wxsxsjx.com
