立式水冷器冷却水量均布技术试验研究

分析了各传热管冷却水量分布不均匀对立式水冷器运行效率的影响，简要评述了企业常用的分布结构存在的问题及其原因，提出了池式均布筛板理论，并且进行了模拟试验和结构参数的优化研究。试验结果表明，均布技术的关键参数是筛板上的积水池深度达到125mm以上时冷却水分布的整体均匀度可以达到85％以上。可以满意地解决现在普遍存在的不均布问题。这种均布技术结构简单，设计方法也十分简便，可以很方便的推广应用。

EXPERIMENTAL RESEARCH ON WATER WELL-DISTRIBUTD TECHNOLOGY FOR VERTICAL WATER COOLERS

This paper analyzes the effect of water not being well - distributed for heat transfer pipes on the operation efficiency of vertical water coolers, briefly reviews the problem of distribution structure commonly used in industry.The new theory of pond distribution sieve-plate is proposed . Optimization study of structure parameter and stimulated experiments show that the key parameter of the distribution technology is the water depth in the pond, which is just on the sieve-plate. When the depth is more than 125 mm, the overall evenness of water distribution can be more than 85% .Thus, the common problem of water not being well-distributed is solved satisfactorily. This distribution technology has simple structure and the design method is easy, so it can be applied in industry conveniently.
