Reduction of scale build-up in an evaporative cooling apparatus

Abstract

A direct evaporative cooler includes a liquid delivery system and an assembly of two or more plates. At least one plate of the assembly of two or more plates may include a top surface having a wicking material with an exposed surface for receiving a liquid thereon from the liquid delivery system, and one or more masks lining a portion of the exposed surface. The one or more masks may be impermeable to the liquid thereby preventing the liquid from evaporating through the one or more masks, and the one or more masks may be sized and shaped such that a wick rate of the liquid on the exposed surface exceeds an evaporation rate of the liquid.
