FAN COOLING TOWER Russian patent published in 2016 - IPC F28C1/00 

FIELD: power industry.

SUBSTANCE: invention relates to the heat-power engineering, can be used for circulated water cooling. The fan cooling tower contains an exhaust tower with air-duct openings along the perimeter of its bottom part, an air trap, a water distribution system with contracting nozzles, and installed symmetrically relatively to the longitudinal axis of the tower, sprinkler and pond divided to sections by the partitions, each of them is made zigzag out of bi-metal with creation ion section of the alternating in staggered order confusers and diffusers, wherein the water distributing system is made by the located in pairs contracting nozzles, and on the internal surface of each pair of nozzles the curvilinear grooves located longitudinally from the large base to small base are made, wherein in the first nozzles pair the guide of the curvilinear groove is directed CW, and in the second nozzles pair the guide of the curvilinear groove is directed CCW, wherein the exhaust tower has cone nozzle with hollow shaft, on which the wind wheel with curvilinear cavities and impeller is secured, wherein the curvilinear blades of the wind wheel and impeller during mutual synchronous movement create the contracting nozzle of rotation; besides, in the hollow shaft between the wind wheel and impeller the output openings are made for the venting air, and the wind wheel is connected with electric accumulating device.

EFFECT: reduced additional energy consumption die to presence of the increased humidity of the atmosphere vented air during the circulating water cooling during long-term operation.
