摘要
凝结换热试验结果表明，所试验的水平单头螺旋槽铜管管外水蒸气凝结换热系数约为光管的两倍；通过理论分析，得到了考虑表面张力作用的水平单头螺旋槽的管凝结换热准则方程．
The dimensionless equation of condensation enhantal by surface forces horizonal spirallycorragated tube is presented,The results of exporiment show that condensation heat transfer coefficientas for horizonae spirally corrugatred tube is approxirnately tuice higher than that of the smooth tube.
