翅片管散热器是气体与液体热交换器中使用较为广泛的一种换热设备。它通过在普通的基上加装翅片来达到强化传热的目的。基可以用钢管;不锈钢管;铜管等。翅片也可以用钢带;不锈钢带,铜带,铝带等。不管是单金属的翅片管或者是双金属的翅片管,其都是翅片管的一种类型,而翅片管就是我们常说的散热器,因为在用途上有所不同,且结构和特点的不同等,所以翅片管在分类上也比较多样化,今天翅片管厂家重点介绍单金属和双金属翅片管的区别:翅片管是我们换热器中常用的一种换热原件,在这些翅片管中,每种分类的翅片管的作用都有所不同,今天我们就来讲讲双金属复合翅片管与单金属复合翅片管的区别吧。

Whether it is single metal finned tube or bimetal finned tube, it is a type of finned tube, and finned tube is what we often call radiator. Because of the difference in use, structure and characteristics, the classification of finned tube is also more diversified. Today, finned tube manufacturers focus on the difference between single metal and bimetal finned tube: finned tube is me In these finned tubes, the function of each type of finned tube is different. Today, let's talk about the difference between bimetal composite finned tube and single metal composite finned tube.

单金属复合翅片管由铝管整体轧制而成,称铝轧翅片管,无接触热阻,强度高,耐热和机械震动,热膨胀性能好,且具有可观的扩展换热面。用这种翅片管制成的换热器,效果领先于串片或绕片式换热器,是一种用途很广的换热器。单金属复合翅片管也可由钢管直接轧制或者铜管轧制而成。

Single metal composite finned tube is made by rolling aluminum tube as a whole. It has no contact thermal resistance, high strength, heat resistance and mechanical vibration, good thermal expansion performance and considerable expansion heat exchange surface. The effect of the heat exchanger made of this kind of fin tube is better than that of the heat exchanger with series or wound fins. Single metal composite finned tube can also be directly rolled from steel tube or copper tube.

双金属复合翅片管分为钢铝复合翅片管和铜铝复合翅片管。钢铝复合翅片管是由(钢管、铝管;或不锈钢管、铝管)经复合后再轧制出翅片,铜铝复合翅片管由(铜管、铝管)经复合后再轧制出翅片,具有结合紧密、热阻小、传热性能好、强度高、流动损失小、防腐蚀性能强、在长期冷热工况下不易变形,工作寿命长等优点。

Bimetal composite finned tube is divided into steel aluminum composite finned tube and copper aluminum composite finned tube. Steel aluminum composite finned tube is composed of (steel pipe, aluminum tube; or stainless steel tube, aluminum tube) and then rolled out of fin; copper aluminum composite finned tube is rolled out of fin by (copper tube, aluminum tube) after lamination. It has the advantages of close combination, small thermal resistance, good heat transfer performance, high strength, small flow loss, strong corrosion resistance, not easy to deform under long-term cold and hot conditions, and long working life.

整体轧制翅片无毛刺、无皱折、易于清洗、在采暖空调工程中进行湿式冷却时易排除翅片外表面凝结水,在烘燥加热及其它热交换场合不易结尘、结垢。单金属的翅片管主要是利用铝管,并采用整体的轧制技术制造而成,所以还可以将其称之为铝轧翅片管,和热阻之间没有任何的基础,强度非常高,不仅耐热还非常的耐机械的振动,整个热膨胀性能也比较良好,可以在换热面上进行有效的扩展。利用单金属翅片管制造而成的换热器,在使用的效果上高出绕片式的换热器很多,用途也较为广泛,而且单金属的翅片管,还可以利用铜管或者是钢管进行轧制,由于轧制的材料不同,所以使用的范围和用途也不同。

The integral rolling fin has no burr, no wrinkle, easy to clean, easy to remove condensation water on the surface of fin when wet cooling in heating and air conditioning engineering, and is not easy to dust and scale in drying heating and other heat exchange occasions. Single metal finned tube is mainly made of aluminum tube and made by integral rolling technology, so it can also be called aluminum rolling finned tube. There is no foundation between it and thermal resistance. Its strength is very high. It is not only heat-resistant, but also very resistant to mechanical vibration. The whole thermal expansion performance is relatively good, which can be effectively extended on the heat exchange surface. The heat exchanger made of single metal finned tube is much higher than that of wound plate heat exchanger, and its application is more extensive. Moreover, the single metal finned tube can also be rolled by copper tube or steel pipe. Due to the different rolling materials, the scope and use of the heat exchanger are also different.

双金属的翅片管还可以分为铜铝复合的翅片管,或者是钢铝的复合翅片管两种,其中钢铝的复合翅片管是直接轧制出来的,而铜铝的复合翅片管则是经过复合之后再轧制,所以两者之间具备较多的不同,因此在使用性能上也有所不同。而且双金属的翅片管在结合上较为紧密,热阻也非常小,传热的性能比较优质,强度也非常高,而且在流动的损失上较小,主要的还是防腐蚀的性能比较强,可以比较长时间的在冷热的工况下使用,并不会出现任何的变形。利用整体轧制方式的翅片管不会出现毛刺和折皱的现象,而且清洗起来也更加方便,如果使用在采暖的空调中,可以比较便捷的将外表面的凝结水进行排出,而在烘燥和加热,或者是其他的热交换的场合下使用,还不容易出现结垢或者是结尘等不良。

Bimetallic finned tube can also be divided into copper aluminum composite finned tube or steel aluminum composite finned tube. Steel aluminum composite finned tube is directly rolled out, while copper aluminum composite finned tube is rolled after composite rolling, so there are many differences between the two, so the performance is also different. Moreover, the bimetallic finned tube is closely combined, the thermal resistance is very small, the heat transfer performance is relatively high, the strength is also very high, and the flow loss is small, the main or corrosion resistance performance is relatively strong, can be used for a long time in cold and hot conditions, and will not appear any deformation. The finned tube with integral rolling method will not appear burr and wrinkle phenomenon, and it is more convenient to clean. If it is used in heating air conditioning, it can be more convenient to discharge the condensate on the external surface. However, when it is used in drying and heating or other heat exchange occasions, it is not easy to have scaling or dust deposition.

翅片式散热器目前使用较广泛的是钢铝翅片管(绕片式钢铝复合型翅片管、轧片式钢铝复合型翅片管)它利用了钢管的耐压性和铝的高效导热性能,在专用的机床上复合而成。其接触热阻在210℃的工作情况下几乎为零。翅片管散热器一般用于加热或冷却空气,具有结构紧凑,单位换热面积大等特点。广泛应用于纺织,印染,石油,化工,干燥,电力等各个领域。
