Advantages of High Frequency Welded Sawtooth Finned Tubes Under the same heat transfer medium environment, open fins greatly increase the contact probability of high-temperature flue gas and fins compared with non-open fins, and correspondingly improve the heat transfer effect of fins. The average heat transfer coefficient is 5-13 higher. percentage point, and due to the opening of the fin, the circulation area of the flue gas and the wind tunnel effect are increased, and the pressure difference on both sides of the fin is reduced. The resistance of the open fin tube is about 20% lower, which improves the heat transfer efficiency and prevents accumulation. The role of ash.
