NATURAL DRAUGHT EVAPORATION COOLING TOWER WITH EXTERNAL HEAT EXCHANGE Russian patent published in 2014 - IPC F28C1/00 F28F25/00 

FIELD: power engineering.

SUBSTANCE: natural draught evaporation cooling tower comprises an exhaust tower with air inlet windows in its base, a water-collecting pond, a water-distributing system and an irrigation device, and also air guiding shields located outside the exhaust tower at the angle to the radius of the tower base. The water-distribution system and irrigation device are taken outside from the exhaust tower and are covered with a roof on top, arranged above air inlet windows, and at the bottom the base is created with inclination towards the water-collecting pond. The water-distribution system is arranged under the roof above the air inlet windows and is made in the form of a circular pipe with nozzles, on which water sprayers are installed. The irrigation device is made in the form of air guiding shields arranged outside the exhaust tower at the angle to the radius of the tower base.

EFFECT: increased thermal efficiency of natural draught evaporation cooling towers, increased effectiveness of heat exchange.
