Abstract：
Aiming at the issue of the uniformity of water distribution in indirect evaporative coolers, based on the improvements of structure of water distributors and the selection of water absorbing materials, presents specific measures and conducts some accordingly experimental studies. The results show that these measures can improve the uniformity of water distribution, enlarge the surface wettability coefficient and enhance the heat and mass exchange effectiveness of indirect evaporative coolers.
