在换热器设计手册（HEDH）中给出的冷凝器设计程序中，没有确定折流板间距的精确标准。为了在设计过程中考虑合适的折流板间距，编制了一个计算机程序，使设计人员能够确定节段折流板壳管式冷凝器的最佳折流板间距。该方法以换热面积和泵送功率的总费用为目标函数，根据所需地点的经济条件，采用加权因子。最后，提出了一套确定最佳折流板间距的相关公式，可作为HEDH建议的补充。
There is no precise criterion to determine baffle spacing in the presented procedure for condenser design in the Heat Exchanger Design Handbook (HEDH). To consider suitable baffle spacing in the design process, a computer program has been developed which enables designers to determine the optimum baffle spacing for segmentally baffled shell and tube condensers. Total costs of heat transfer area and pumping power are involved to perform objective function, using a weight factor, which depends on the economical conditions of the desired location. As a result, a set of correlation is presented to determine the optimum baffle spacing, which could be considered as a complementary to HEDH recommendations.
