摘　　要：本文介绍低翅片螺纹管流动沸腾传热强化和折流杆流动沸腾两相流压降分析模型，并提出了螺纹管折流杆流动沸腾的试验结果和曲线。试验表明其压降甚小，而强化传热是光管束的２．７～３．９ 倍。In the paper, the analyzing model of the flow boiling and two-phase-flow pressure drop of Rodbaffle reboiler with thread tube were presented. The experimental results and testing curves were given. It showed that Pressure drop in reboiler is so low and but the highest enhanced effects is 2 7~3 9 times as bare tube bundle
