There are many kinds of finned tubes, and the copper-aluminum composite finned tube is a kind of finned tube. The finned tube has two kinds of inner finned tubes and outer finned tubes according to different mounting positions of the fins, and the outer finned tubes are more commonly used。 Depending on the arrangement of the fins, there are two types of finned tubes: longitudinal finned tubes and horizontal finned tubes。 According to the shape of the fin tube, the fin tube has a round fin tube, an elliptical fin tube, and a flat tube fin tube. At present, the circular finned tube heat exchanger dominates the market, but a large number of experiments have shown that the reflow area and the windward area of ​​the elliptical tube are much smaller than the round finned tube, effectively reducing the flow resistance of the air side A. Reduced energy consumption. When the number of tube bundles is present at the same time, the elliptical tube and the flat tube are tighter than the round tube structure. The heat exchanger is small in size and reduces the cost.
