双侧强化换热高效冷凝传热管的试验研究

Experimental Investigation of DoubleSide Augmented HeatConducting HighPerformance Condenser Tube

介绍了双侧强化高效冷凝换热管的试验研究方法。所用试验装置保证在同样蒸气状态下，对光滑管和高效传热管同时进行直接对比的性能测定。对氨蒸气凝结试验的结果表明，高效传热管的平均传热系数比光滑管提高４０％以上。

In this paper, the experimental investigation method of the doubleside augmented heatcondueting highperformance condenser tube is introduced. The experimental results for the vapor condensation of NH3 at the outside show that the average coefficient of the doubleside augmented highperformance heatconducting condenser tube can be increased 40% as compared with the smooth tube.
