The fin material extrudes around the outside of the tube.<\/span><\/p><p>\u00a0<\/p><p><span style=\"color: #000000;\">This manufacturing process creates a tight mechanical bond between the fin and tube.<\/span><\/p><p>\u00a0<\/p><p><span style=\"color: #000000;\">Unlike some welded fin tube designs, continuous welding does not hold the fin to the tube with extruded fins.<\/span><\/p><p>\u00a0<\/p><p><span style=\"color: #000000;\">Instead, the aluminum extrusion process creates a strong mechanical bond.<\/span><\/p><p>\u00a0<\/p><p><span style=\"color: #000000;\">Typically, aluminum is the fin material of choice due to its thermal conductivity and light weight.<\/span><\/p><p>\u00a0<\/p><p><span style=\"color: #000000;\">At the same time, the tube inside can be made from carbon steel, stainless steel, copper, or other alloys.<\/span><\/p><p>\u00a0<\/p><p><span style=\"color: #000000;\">Ultimately, this creates a strong tube with a large external heat transfer surface area.<\/span><\/p><p>\u00a0<\/p><p><span style=\"color: #000000;\">Consequently, <strong>extruded fin tubes<\/strong>\u00a0offer an efficient solution to heat transfer on the air-side of heat exchangers.<\/span><\/p><p>\u00a0<\/p><p><a href=\"https:\/\/customindustrialheatexchanger.com\/shop\/fin-tube-machine\/extruded-fin-tube-machine\/extruded-fin-tube-machine\/\"><span style=\"color: #000000;\"><strong><em><u><i>Extruded Fin Tube Machine<\/i><\/u><\/em><\/strong><em><u><i>\u00a0<\/i><\/u><\/em><\/span><\/a><\/p><p>\u00a0<\/p><h2><span style=\"color: #000000;\"><strong>3. How Do Extruded Fin Tubes Work? <\/strong><\/span><\/h2><p>\u00a0<\/p><p><span style=\"color: #000000;\">The basic function of <strong>extruded fin tubes<\/strong>\u00a0is simple enough.<\/span><\/p><p>\u00a0<\/p><p><span style=\"color: #000000;\">By adding fins to the outside of the tube, you increase the external surface area.<\/span><\/p><p>\u00a0<\/p><p><span style=\"color: #000000;\">For instance, air generally has a lower heat transfer capacity than water.<\/span><\/p><p>\u00a0<\/p><p><span style=\"color: #000000;\">Therefore, increasing the surface area on the air-side of the heat exchanger can improve its design.<\/span><\/p><p>\u00a0<\/p><p><span style=\"color: #000000;\">During operation, heat conducts from the fluid inside the tube through the tube wall.<\/span><\/p><p>\u00a0<\/p><p><span style=\"color: #000000;\">From there, heat moves to the fins and spreads through the larger surface area of the fins.<\/span><\/p><p>\u00a0<\/p><p><span style=\"color: #000000;\">Lastly, air or another fluid removes heat from the fin externally.<\/span><\/p><p>\u00a0<\/p><p><span style=\"color: #000000;\">Through this process, a relatively small tube can exchange heat with a larger volume of air.<\/span><\/p><p>\u00a0<\/p><p><span style=\"color: #000000;\">Additionally, the continuous fins provide a constant surface area for heat transfer along the tube length.<\/span><\/p><p>\u00a0<\/p><p><span style=\"color: #000000;\">As a result, <strong>extruded fin tubes<\/strong>\u00a0allow for consistent thermal performance in many heat exchanger applications.<\/span><\/p><p>\u00a0<\/p><h2><span style=\"color: #000000;\"><strong>4.
