An evaporative cooler apparatus and method of operation are disclosed. The invention was conceived and developed to humidify and cool the attic space between the roof and the ceiling of man-made buildings or other structures. The apparatus is comprised of an induced draft fan assembly which blows air through an evaporation bundle comprised of one or more concentric cylinders of fibrous evaporation pads. The most advantageous embodiments of the invention and optimum parameters of operation result in reduced costs for installation, for evaporation water, for electrical power, and for service and maintenance as compared with devices of the prior art.

An evaporative cooler apparatus comprising in combination: a. An induced draft fan, mounted within the attic of a building or structure to facilitate intake of outside, ambient air through a screened intake vent; b. An adapter section which receives air from the fan, and provides conduit for the air into the evaporation bundle; and receives excess evaporation water from the evaporation bundle, and provides conduit for said water into a water drain pipe or conduit; c. An evaporator bundle comprised of concentric elements such as cylinders of fibrous pad media within a containment shell; d. A means for suspension or support of said evaporation apparatus in an inclined position within the attic space of said structure to provide natural capillary and gravity flow of evaporation water from the higher end of said evaporation bundle to the lower end of said evaporation bundle; e. A conduit and flow control system to supply evaporation water to said evaporation bundle; said flow control system including trickle irrigation nozzles which are affixed to the top surface of each evaporation element said irrigation nozzles spaced to provide even distribution of evaporation water throughout the evaporation pads by the action of gravity and capillary flow of said evaporation water; f. Annular spacers to support the evaporation elements within the containment shell of the evaporation bundle in an array to facilitate equalized air velocity in all annular spaces between the evaporation elements, and facilitating flow of air with minimum resistance; g. A supporting means, such as a restraining bar, to prevent telescoping movement of the elements of the evaporation bundle.
