ABSTRACT:
An evaporative cooler having an evaporation pad shaped to extend essentially circularly about a blower to define an essentially circular chamber into which the blower draws air through the pad to evaporate moisture therefrom. The chamber may have oppositely convex top and bottom walls, with the blower preferably discharging downwardly through the bottom wall. Water is fed to the top of the pad through a tube extending circularly along the upper edge of the pad and containing water under pressure and having spaced openings through which the water discharges onto the pad.
