露点间接蒸发冷却器湿通道侧材料亲水性研究

To explore the performance of hydrophilic materials on the wet channel side of a dew point indirect evaporative cooler. The hydrophilic properties of the materials were verified and compared by testing the wicking height, water droplet spreadability, moisture absorption and desorption, and surface structure of six hydrophilic material samples. The tests proved that polymer fiber materials and Coolpass fiber materials have better moisture absorption and desorption performance, and have greater diffusion ability and better evaporation ability under the action of moisture capillarity. It is considered that the selection of excellent hydrophilic materials can greatly tap the efficiency potential of the dew point indirect evaporative cooling system.
