SHORT-LAYERED COOLING TOWER SPRINKLER Russian patent published in 2012 - IPC F28F25/08 

FIELD: machine building.

SUBSTANCE: short-layered cooling tower sprinkler consists of corrugated sheets assembled into packets and installed vertically and parallel to the oppositely directed corrugations on adjacent sheets; the sheets with slanting corrugations alternate with the sheets of with straight corrugations. Height of the sprinkler packets is within the limits defined by a ratio H=m·d_e, where h is height of sprinkler packets, m is a coefficient equal m=3÷6, d_e is an equivalent diameter of the irrigator channel equal d_e=4F/p, F is area of the living section of the irrigator channel hole, P is perimetre of the irrigator channel hole. In each subsequent sheet with straight corrugations direction of the corrugation is changed to 90°. The straight corrugations are made of trapezoidal section. The slanting corrugations on sheets are made with the slope angle α=65÷85° relative to a horizontal edge of the sheet. In each subsequent sheet with slanting corrugations direction of the corrugation is changed to the opposite. The slanting corrugations are made of triangle section. The sprinkler packets are in a cooling tower are stacked in several layers, with the packets located relative to one another rotated by 60÷90°.

EFFECT: intensification of heat exchange and mass exchange while minimising flow resistance.
