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

and reduce noise. The capillary-networked closed cooling towers have better technical and economic performance.
