Structure Analysis on Liquid Distributor at the Tube Box Entrance of Plate Air -Cooled Cooler

Abstract

Abstract:

Plate air -cooled cooler is a new kind of coolers that combines the merits of both plate heat exchanger and air -cooled heat exchanger .It has better water -saving and less environment -polluting characteristics , and combines high efficiency with more circulation areas of plate heat exchanger .So it' s a new kind of advanced, high efficient and energy -saving heat exchanger .Since plate bundles of plate heat exchangers were designated vertically , while the medium enters plate bundles, the uniform level has an important influence on coo ling efficiency .Pushing force, outflow mode , jam possibility , resistance to liquid , influence by erosion,operation flexibility , weight and distributed mass of three kinds of liquid distributors were analyzed.Distributed mass and pressure drop of liquid distributors are analyzed.The structure design ideas and evaluation criterion are obtained.

Key words: 　Air -coo led cooler , 　Distributor , 　Efficiency , 　Pressure drop

摘要： 板式空冷器是一种将板式换热器与空冷式换热器的优点结合的新型空冷器。它既具有空冷器节水效果好、环境污染小的特点, 又综合了板式换热器传热效率高、流通面积大的特点, 是一种先进的新型、高效、节能型换热设备。由于板式空冷器的板束为垂直设计, 因此, 介质进入板束时的均布水平对于空冷器的冷却效率有着重要的影响。分析了导流板式、分布管式、筛板式3 种液体分布器的推动力、流出方式、堵塞可能性、对流体阻力、分布受腐蚀的影响、操作弹性、质量、分布质量等性能, 分析了液体分布器的分布质量与压力降。得出了其结构设计的基本思想与评价方法。
