The difference between bimetal finned tube and single metal finned tube

Finned tube is a common heat exchange component in our heat exchangers. In these finned tubes, the functions of finned tube in each category are different, the differences are as follows:
Single metal composite finned tube is made of aluminum tube rolled as a whole, called aluminum rolled finned tube, no contact thermal resistance, high strength, heat resistance and mechanical vibration, good thermal expansion performance, and has considerable expansion heat transfer surface. This kind of fin tube heat exchanger, the effect is preferred to the series or wrap heat exchanger, is a very wide use of heat exchanger. The single metal composite finned tube can also be directly rolled by steel tube or copper tube.

The 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 tube, aluminum tube; Or stainless steel tube, aluminum tube) after composite rolling again after a fin, copper aluminum composite finned tube by (copper tube, aluminum tube) through a composite rolling again after a fin, is tightly bound, small heat resistance, heat transfer performance is good, high strength, small flow loss, strong corrosion resistance performance, in cold and hot condition for a long time is not easy to deformation, long working life.
The whole rolled fins have no burr, no wrinkle, easy to clean, easy to remove the condensation water on the outer surface of the fins during wet cooling in heating and air conditioning projects, and not easy to form dust and scale in drying heating and other heat exchange occasions.
