Abstract
An evaporative cooler body comprises a non-corrosive, insulative assembly of self-locating, self-jigging parts. Stand-off means are provided for increasing the effective area of the evaporative cooling pads and for improving air flow across the surface of and through said pads. An improved water distribution means permits sheeting of the water across the top surfaces of the evaporative cooling pads to obtain a more uniform distribution of water within said pads. Means are provided for interrupting water flow on the surface of the evaporative cooling pads and returning such water to the interior of said pad so as to increase the overall efficiency of the evaporative cooler. The evaporative cooler cabinet is comprised of a minimal number of reaction injection molded elements of high modulus urethane elastomer. The material insulates both sound and heat providing a quieter running and more cooling-efficient device. Color may be permanently molded into the cabinet. The cabinet will not rust, chip, corrode or fade. Precision molding of the elements permits the cabinet to be assembled readily without the need for welding, rivets, screw fasteners or the like since the precision fit of the…
