Summary

USUALLY, A LOT OF CONDENSED WATER REMAINS ON THE FIN SURFACES OF AN AIR COOLER, THUS INCREASING THE PRESSURE DROP OF AIR FLOW THROUGH AN AIR COOLER. THE HYDROPHILIC COATING WAS CONFIRMED TO BE VERY EFFECTIVE FOR REDUCING THE PRESSURE DROP AND THE RESULTS OBTAINED WERE AS FOLLOWS: 1) THE HYDROPHILIC COATING, CONSISTED OF A PLASTIC PAINT, SYNTHETIC SILICA AND SURFACE ACTIVE AGENT, IMPROVES THE WETTABILITY OF THE FIN SURFACES. 2) THE PRESSURE DROP THROUGH THE AIR COOLER IS ABOUT 40 PERCENT LESS THAN THAT OF CONVENTIONAL ONES. 3) THE EFFECTIVENESS OF THE HYDROPHILIC COATING HAS BEEN VERIFIED TO BE SUFFICIENTLY VALID FOR ACTUAL USE.
