【摘要】 冷冻水冷器各传热管的冷却水量分布不均匀使其冷却效率普遍较低。本文简要评述了目前常用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 12 5mm以上时 ,冷却水分布的整体均匀度可达 85 %以上 ,可以较好地解决现有设备普遍存在的不均布问题。这种均布技术简单可行 ,设计方法也十分简便 ,可以较方便地推广应用。更多还原

【Abstract】 The generally low operation effciency of vertical water cooler is due to the ununiformity of the cooling water distribution in each heat transfer tube. The problem existed in the distribution structure was briefly analyzed, and a new design of pond-distribution sieve-plate was proposed. Optimization studies and simulation experiments showed that the water depth in the pond, which is on the sieve-plate, is the key parameter for water distribution. When the depth is greater than 125 mm,the overall evenness of water distribution is more than 85%. The new structure is simple and the design method is easy for industry application.更多还原
