SPRAY BOND Russian patent published in 2004 - IPC

FIELD: water coolers of circulating systems of thermal and nuclear power stations, applicable for cooling of hot water at industrial enterprises. SUBSTANCE: the spray bond has a water-supply pipe-line connected to the pressure header positioned above the pond with a group of spray nozzles in the form of rows separated by air passageways with different heights of the flame, connected in the lower part of the pressure headers are pipe-lines lowered in the direction of the water surface and installed with the aid of floats at the level of the surface, made in the form of posts connected by flexible corrugated inserts with ejectors made on whose inner surface of the expansible parts are helical grooves, the posts with the ejectors in the length of the pressure headers are positioned by pairs that are oriented by their expansible parts towards each other, made on the inner surface of the expansible part of the first of the pair ejectors are helical grooves, whose curvature has a positive direction of rotation of the helical line, and on the inner surface of the expansible part of the second ejector helical grooves are made, whose curvature has a negative direction of rotation of the helical line. EFFECT: enhanced efficiency of cooling due to improved heat exchange because of the enhanced surface of contact of cooled water and atmospheric air at invariable overall dimensions of the spray. 3 dwg
