摘　　要：为解决闭式冷却塔在冬天停机时排水不尽易冻裂和遇腐蚀性工质易损坏的问题,将工程塑料毛细管网技术引入闭式冷却塔。根据理论计算设计了毛细管网闭式冷却塔,并且进行了实物模块的性能实验。研究表明:在单台塔体大小相同的条件下,两台毛细管网闭式冷却塔能够达到一台常规管径紫铜管闭式冷却塔的散热能力,且换热器部分的成本相差无几,由于毛细管网闭式冷却塔具有防腐、抗冻、阻垢、降噪的优势,所以具有良好的技术经济性。In order to solve the frost crack problem in winter and the tube corrosion problem of corrosive medium in closed cooling towers,engineering plastic capillary-network technology is introduced to the tower.A capillary-networked closed cooling tower was designed by theoretical calculation and the performance of real model has been tested.Research indicates that the heat-exchange ability of two capillary-networked closed cooling towers is similar to a normal closed cooling tower＇s with copper-tubes of the same size.The cost of the heat-exchanger for both towers is almost the same.On account of the capillary-networked closed cooling towers can prevent corrosion,frost crack,foreign matters,and reduce noise.The capillary-networked closed cooling towers have better technical and economic performance.
