Abstract: 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.
