翅片管散熱器是氣體與液體熱交換器中使用較為廣泛的一種換熱設備。它通過在普通的基管上加裝翅片來達到強化傳熱的目的?；?a title="翅片管" target="_blank" class="sitelink">管可以用鋼管；不銹鋼管；銅管等。翅片也可以用鋼帶；不銹鋼帶，銅帶，鋁帶等。不管是單金屬的翅片管或者是雙金屬的翅片管，其都是翅片管的一種類型，而翅片管就是我們常說的散熱器，因為在用途上有所不同，且結構和特點的不同等，所以翅片管在分類上也比較多樣化，今天翅片管廠家重點介紹單金屬和雙金屬翅片管的區別：翅片管是我們換熱器中常用的一種換熱原件，在這些翅片管中，每種分類的翅片管的作用都有所不同，今天我們就來講講雙金屬復合翅片管與單金屬復合翅片管的區別吧。

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.

單金屬復合翅片管由鋁管整體軋制而成，稱鋁軋翅片管，無接觸熱阻，強度高，耐熱和機械震動，熱膨脹性能好，且具有可觀的擴展換熱面。用這種翅片管制成的換熱器，效果領先于串片或繞片式換熱器，是一種用途很廣的換熱器。單金屬復合翅片管也可由鋼管直接軋制或者銅管軋制而成。

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.

雙金屬復合翅片管分為鋼鋁復合翅片管和銅鋁復合翅片管。鋼鋁復合翅片管是由(鋼管、鋁管;或不銹鋼管、鋁管)經復合后再軋制出翅片，銅鋁復合翅片管由(銅管、鋁管)經復合后再軋制出翅片，具有結合緊密、熱阻小、傳熱性能好、強度高、流動損失小、防腐蝕性能強、在長期冷熱工況下不易變形，工作壽命長等優點。

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.

整體軋制翅片無毛刺、無皺折、易于清洗、在采暖空調工程中進行濕式冷卻時易排除翅片外表面凝結水，在烘燥加熱及其它熱交換場合不易結塵、結垢。單金屬的翅片管主要是利用鋁管，并采用整體的軋制技術制造而成，所以還可以將其稱之為鋁軋翅片管，和熱阻之間沒有任何的基礎，強度非常高，不僅耐熱還非常的耐機械的振動，整個熱膨脹性能也比較良好，可以在換熱面上進行有效的擴展。利用單金屬翅片管制造而成的換熱器，在使用的效果上高出繞片式的換熱器很多，用途也較為廣泛，而且單金屬的翅片管，還可以利用銅管或者是鋼管進行軋制，由于軋制的材料不同，所以使用的范圍和用途也不同。

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.

雙金屬的翅片管還可以分為銅鋁復合的翅片管，或者是鋼鋁的復合翅片管兩種，其中鋼鋁的復合翅片管是直接軋制出來的，而銅鋁的復合翅片管則是經過復合之后再軋制，所以兩者之間具備較多的不同，因此在使用性能上也有所不同。而且雙金屬的翅片管在結合上較為緊密，熱阻也非常小，傳熱的性能比較優質，強度也非常高，而且在流動的損失上較小，主要的還是防腐蝕的性能比較強，可以比較長時間的在冷熱的工況下使用，并不會出現任何的變形。利用整體軋制方式的翅片管不會出現毛刺和折皺的現象，而且清洗起來也更加方便，如果使用在采暖的空調中，可以比較便捷的將外表面的凝結水進行排出，而在烘燥和加熱，或者是其他的熱交換的場合下使用，還不容易出現結垢或者是結塵等不良。

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.

翅片式散熱器目前使用較廣泛的是鋼鋁翅片管（繞片式鋼鋁復合型翅片管、軋片式鋼鋁復合型翅片管）它利用了鋼管的耐壓性和鋁的高效導熱性能，在專用的機床上復合而成。其接觸熱阻在210℃的工作情況下幾乎為零。翅片管散熱器一般用于加熱或冷卻空氣，具有結構緊湊，單位換熱面積大等特點。廣泛應用于紡織，印染，石油，化工，干燥，電力等各個領域。
