COOLING TOWER WITH AIR CONTROL DEVICES Russian patent published in 2015 - IPC F28C1/00 

FIELD: power industry.

SUBSTANCE: evaporative cooling tower includes a stack at the base of which there are air inlet openings with turning flow control shields with a horizontal rotation axis and air guide shields with a vertical rotation axis, which are located at the air inlet openings. The cooling tower includes turning air guide shields with the horizontal rotation axis, which are installed at an angle to horizon inside the stack at the base of the air inlet openings. The turning flow control shields with the horizontal rotation axis and the air guide shields with the vertical rotation axis are made in the form of a single structure installed in all air inlet openings and consisting of three shields with a horizontal rotation axis, which are located in the centre, and two shields with a vertical rotation axis, which are located on edges. The invention allows controlling intensity and uniform distribution of an airflow in winter time as a result of combined use of turning shields with horizontal and vertical rotation axes.

EFFECT: increasing thermal efficiency of stack-type evaporative cooling towers.
