摘要：
The heat transfer characteristics of flat-high-fin tubes and corrugated-high-fin tubes are investigated in the wind tunnel. It is found that the heat transfer effect of corrugated-high-fin tubes is 1.2 times better than that of flat-high-fin tubes. The corresponding correlation between Nusselt number and Reynolds number is obtained. The mean deviation of the experimental curve from the calculated one is 5.9% for corrugated-high-fin tubes, and 3.8% for flat-high-fin tubes. Meanwhile, the pressure drop for corrugated-high-fin tubes is 1.1 times as large as that for the flat-high-fin tubes. The corresponding correlation between the friction factors and Reynolds number is also gained. The mean deviation of the experimental curve from the calculated one is 6.5% for corrugated-high-fin tubes, and 4.9% for flat-high-fin tubes.
