Abstract:
An evaporative cooler comprising:a liquid distributor; a body having a surface and occupying a first plan area for receiving liquid from said liquid distributor over said surface substantially throughout said first plan area; an air moving device arranged to generate a flow of air; said body surface being positioned in said flow of air and said flow of air causing a small portion of said liquid received by said body to evaporate, thereby cooling a remaining portion; a heat transfer working fluid conduit positioned substantially outside of said flow of air and having a second plan area dimensioned smaller than said first plan area; said heat transfer working fluid conduit having a surface arranged to receive substantially all of the cooled liquid portion from said body thereover in a heat transfer relationship to warm said liquid portion; a flow accelerator positioned between said body and said heat transfer working fluid conduit to accelerate a flow velocity of said non-evaporated liquid by at least 9.5 feet/second (2.9 meters/second) before contacting said heat transfer working fluid conduit, a liquid concentrator arranged between said body and said heat transfer working fluid conduit to concentrate said non-evaporated liquid from said first plan area, substantially into said second plan area; a liquid collector arranged to receive substantially all of the warmed liquid portion from said heat transfer working fluid conduit; a liquid recirculating mechanism arranged to return said warmed liquid portion to said liquid distributor.
