Introduction
The processing technology of cold-rolled aluminum steel finned tube isthat aluminum tube and steel pipe are first processed into bimetalcomposite pipe,and then the fin is formed after mechanical cold rolling.Based on the physical characteristics of aluminum tube,the finned tubewith steel tube as the core and aluminum fin formed by cold rolling aremade into one.The efficiency of using finned tubes is very high, because the heat dissipation of finned tubes is dozens of times higher than that of ordinary bare tubes due to the winding of fins on the base tube. Moreover, the interior of finned tubes is smooth, and the resistance of the medium flowing in the tubes is small. At this point, not only does it improve the heat transfer efficiency of the finned tube, but it also greatly reduces production costs.
It is widely used in steel, petroleum, chemical industry,machinery, shipbuilding, power station, hospital and food industry.
In fact, using extruded finned tubes is very meticulous, as this type of finned tube can effectively greatly increase the contact area. This further enhances the efficiency of thermal energy conversion and enables more efficient use of energy, achieving better results. Therefore, this is a very environmentally friendly and energy-saving device that can play an effective environmental role.
