A highly efficient evaporative cooler having high cooling capacity in relation to its size, wherein the incoming air is directed to flow along an evaporative pad, rather than directly therethrough, resulting in highly efficient temperature reduction of the incoming air.

An evaporative air cooling device, comprising: means defining an air flow passage; air blower means mounted to cause air to flow through the passage; an evaporation pad having a thickness substantially smaller than at least one of its length and width, said thickness being defined by an upstream surface and an opposing surface of the pad, the pad being installed in a portion of the passage, said portion being shaped and sized to generally conform to the length and width of the pad and to be substantially greater in width than the thickness of the pad in the direction of said thickness, so that an unimpeded flow channel of substantial cross sectional area is provided through said portion of the passage, said channel extending substantially both the length and the width of the pad and being bordered on at least one of its sides the upstream surface of the pad; and means wetting the pad with water without prior contact of the water with a stream of air to be cooled.
