Modular floating wateb-cooltng system

Abstract

Abstract AN EVAPORATIVE WATER-COOLING SYSTEM AND METHOD FOR REDUCING THE TEMPERATURE OF HEATED WATER IN AN OPEN FLOW CHANNEL UTILIZES A PLURALITY OF WATER PUMP AND SPRAY UNITS OR MODULES FLOATING IN THE CHANNEL AND ANCHORED AT SEQUENTIAL LOCATIONS THEREALONG. IN A PREFERRED EMBODIMENT, THE MODULES ARE IDENTICAL IN DESIGN, AND EACH INCLUDE AT LEAST THREE SEPARATE FLOATS, A POWER-OPERATED WATER PUMP SUPPORTED BY ONE OF THE FLOATS, AT LEAST TWO SPRAYS SUPPORTED BY OTHERS OF THE FLOATS, AND PIPES CONNECTING THE PUMP TO THE SPRAYS. WITHIN EACH MODULE, THE FLOATS ARE PREFERABLY ALIGNED IN THE DIRECTION OF FLOW, THE PUMP FLOAT BEING CENTERED WITH SPRAY FLOATS UPSTREAM AND DOWNSTREAM, AND THE PUMP INTAKE BEING LOCATED BENEATH AND PROTECTED BY THE OVERHANG OF ITS DISK-SHAPED FLOAT. THE SPRAYS PROJECT WATER UPWARDLY INTO THE ATMOSPHERE FOR EVAPORATIVE COOLING AND RETURN TO THE CHANNEL. THE STANDARDIZED MODULES CAN BE PATTERNED IN FLOW-DIRECTION SEQUENCES AND CROSS-CHANNEL CLUSTERS, PROVIDING A PREDETERMINABLE TEMPERATURE REDUCTION PROFILE UNDER SPECIFIED DESIGN CONDITIONS. THE SYSTEM IS ADAPTED FOR BOTH ONCETHROUGH AND CLOSED-LOOP CHANNELS. AS WATER FLOW RATE, CHANNEL VOLUME AND/OR TEMPERATURE REDUCTION REQUIREMENTS CHANGE, THE PATTERN CAN BE ALTERED ACCORDINGLY, BY EITHER DOWN OR CROSS-CHANNEL MODULE MODIFICATIONS.
