Harmonica Shaped Aluminum Tube

The section of Harmonica Shaped Aluminum Tube is similar to that of Harmonica Shaped Aluminum Tube. It is also called Harmonica Shaped Aluminum Tube. In the process of use, the Harmonica Shaped Aluminum Tube flows through the medium to be cooled. The number of holes of Harmonica Shaped Aluminum Tube is generally 5-25, more than 60, with a wall thickness of 0.2-1.0mm and a height of about 5mm. It is used to make a belt condenser. The user first coiled the Harmonica Shaped Aluminum Tube on a special mould into a serpentine shape, and then covered with 0.15-0.20mm thick composite foil The processed wave radiator is assembled with the Harmonica Shaped Aluminum Tube, and then welded into the condenser of the heat exchange system in the inert gas brazing furnace.
Alloy and specification



The Harmonica Shaped Aluminum Tube has thin wall, many holes and small inner cavity area. It should be extruded with alloy with good shaping, strong fluidity, moderate strength, good weldability and high corrosion resistance. Most of the first series of alloy are used. 1035 is used in China, The microstructure of 1050 and 1070 alloy, Harmonica Shaped Aluminum Tube weld shall be free of defects, and shall not crack during cold deformation. The bursting pressure that can bear is > = 8N / mm2. The processing plant uses 5-8mn extruder for extrusion. In order to improve the corrosion resistance of Harmonica Shaped Aluminum Tube, alloy 3003,3102 can be used, and Alloy 6063 can be used to improve the pressure bearing capacity of Harmonica Shaped Aluminum Tube.
