PLATE FOR SPRINKLER OF WATER-COOLING TOWER Russian patent published in 2005 - IPC

FIELD: heat exchange apparatus.

SUBSTANCE: plate comprises flat section at the top edge of the plate provided with longitudinal stiffening rib and sinusoidal corrugation arranged over the height of the plate and made of two or more sections with opposite inclination of corrugations. The sides of the corrugations are provided with projections. The bottom section of the corrugations of the sprinkler ends either in closed or semi-closed rhomboid or corrugated slot with parallel walls. The plate of the sprinkler is provided with three layers of corrugation. The sinusoidal corrugations of adjacent parts are either inclined in opposite directions or in the same vertical direction keeping the height and horizontal width of the sinusoidal corrugations to be constant. The smaller inclination angles to the horizon is greater of the smaller angle of inclination of the subsequent section, and projections made of wave-like corrugation on the surface of each section is perpendicular to the sinusoidal corrugations to provided 90° between the direction of the sinusoidal corrugations with respect to the wave-like corrugations arranged on them. The surface of the sprinkler plate is provided with grain corrugation whose height is 0.01-0.5 of the height of the wave-like corrugations made of horizontal strips of height within 0.01-1.0 of the height of corresponding section of the sprinkler plate. The flat section with stiffening ribs can be arranged on any side of the four-side sprinkler plate.

EFFECT: enhanced efficiency of cooling.
