本文对水平管外及管束间的凝结换热计算作了比较分析，分析了现有的几种流速修正 系数以及管束修正系数具体算法之间的差别，提出了较为合理的管束修正系数的计算式。
In this paper, the calculation of condensation heat transfer between horizontal tubes and tube bundles is comparatively analyzed. The differences between the existing flow velocity correction coefficients and the specific algorithms of the tube bundle correction coefficients are analyzed. A more reasonable calculation formula of the correction coefficient of the tube bundle .
