Device having nano-coated porous integral fins

Abstract

Disclosed herein is an apparatus including a plurality of nano-coated, porous integral fins and/or grooves on the evaporator tubes. In some examples, the apparatus is an evaporative cooler, such as a horizontal-tube, falling-film evaporator. In some examples, the evaporator tubes are in either a horizontal and/or tilted and/or vertical position. Also disclosed are methods of using the disclosed apparatus, such as a cooling device including as an evaporative cooler.
