An indirect evaporative cooler assembly includes staggered wet and dry channels. An electric fan moves air through the assembly. Air passes through the wet channels where a material wicks moisture stored in a reservoir into the wet channels. As a result, the side walls of the wet channels are evaporatively cooled. Air moving through dry channels is cooled by the cooling of the walls of the wet channels, and by the presence of louvered convoluted fins in the dry channels that allow for air circulation and further heat dissipation. The wet channels are distinguished by the presence of an electrolyte saturating the material, and electrodes disposed on either side of the material combined to generate an electrical current. Pairs of electrodes are connected in series, and generate electricity to power the electric fan. An auxiliary power source is activated when the voltage from the electrodes drops below a pre-determined level.

An assembly as set forth in claim 4 including a dry system detector for signaling a low level of water in said reservoir. 7. An indirect evaporative cooler assembly comprising; a dry channel for passing ambient air, a wet channel for passing air and in heat conducting relationship with said dry channel, a moisture containing material disposed in said wet channel for evaporating moisture into air passing through said wet channel to cool air passing through said dry channel, characterized by an electrolyte saturating said material for producing electrical voltage, a positive electrode, a negative electrode, said material being disposed between said electrodes for establishing current flow between said electrodes, and a plurality of said wet channels each defined by box-like structure. 8. An assembly as set forth in claim 7 wherein said adjacent wet channels are separated by one of said dry channels. 9. An assembly as set forth in claim 8 wherein with said dry channels and said wet channels are disposed transversely to one another for directing air flow horizontally through said dry channels and directing air flow vertically through said wet channels. 10. An assembly as set forth in claim 9 wherein said wet channels include oppositely facing side walls, and including a plurality of pairs of said positive and negative electrodes separated by said material sandwiched between each pair of said electrodes and extending between said side walls, said pairs of electrodes being spaced from one another horizontally along said box-like structure. 11. An assembly as set forth in claim 10 wherein said material is disposed on said side walls between adjacent pairs of said electrodes. 12. An assembly as set forth in claim 9 wherein said pairs of electrodes are connected in series. 13. An assembly as set forth in claim 10 wherein said walls of said wet channels define a plurality of passageways between said wet channels and said dry channels for allowing a portion of air flowing into said dry channels to enter said wet channels. 14. An assembly as set forth in claim 13 including a plurality of convoluted fins spaced vertically from one another and extending between said side walls of said wet channels within said dry channels. 15. An assembly as set forth in claim 14 wherein said convoluted fins are wired in and brazed at apexes within said dry channels from the side walls of the wet channels for holding and vertically separating the convoluted fins in the dry channels. 16. An assembly as set forth in claim 15 wherein said convoluted fins include a plurality of louvers for enhancing the heat transfer with the air flow. 17. An assembly as set forth in claim 14 wherein said wet channels include end walls extending between said side walls and including an air flow divider disposed over each of said end walls for directing air flow into said adjacent dry channels. 18. An indirect evaporative cooler assembly comprising; a dry channel for passing ambient air, a wet channel for passing air and in heat conducting relationship with said dry channel, a moisture containing material disposed in said wet channel for evaporating moisture into air passing through said wet channel to cool air passing through said dry channel, characterized by an electrolyte saturating said material for producing electrical voltage, wherein said electrolyte comprises non-conductive metallic salt rendered conductive in the presence of water, a positive electrode, and a negative electrode, said material being disposed between said electrodes for establishing current flow between said electrodes.
