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.

Abstract: In one embodiment, a plate for an evaporative cooler is disclosed. The plate may comprise a wicking material with an exposed surface and a sealed surface opposite the exposed surface. An impermeable barrier may be coupled to the sealed surface. One or more masks may line a portion of the exposed surface, wherein the masks may comprise an impermeable material. In some embodiments, the mask may be a strip of impermeable material and may be coupled to a flat area of the top surface. In further embodiments, the one or more masks may align with a liquid wick path of the wicking material. In further embodiments, the one or more masks may line the edge of perforations that pass at least partially through the plate.
