摘要
在板式换热器的蒸汽凝结换热试验台上进行了实验研究，获取蒸汽完全凝结和部分凝结两种典型工况下的换热和压降特性．且就板式换热器中蒸汽凝结过程的换热进行分析和处理，得到了一个在板片槽道中蒸汽凝结换热系数关联式．并推荐用于板式换热器的蒸汽凝结换热系数的计算．
Cooperating with Alfa Laval Thermal Company of Sweden, a steam condensation test rig of plate heat exchanger(PHE) was set. The heat transfer and pressure drop characteristics of two kinds of typical operation condition in PHE were obtained (complete condensation and partial condensation). In this paper, the process of steam condensation in PHE is analyzed in detail. Based on the data processing of experimental points, a correlation of steam condensation heat transfer coefficient in wavy plate channel is got, which can be recommended to calculate steam condensation heat transfer coefficient in PHE.
