COOLING TOWER PACKING UNIT Russian patent published in 2017 - IPC F28F25/08 

FIELD: water supply.

SUBSTANCE: invention relates to recycling water supply, specifically to structural elements of cooling towers and other devices for heat-mass exchange between liquid and gaseous media, in particular, to cooling towers of sprinklers and water catchers elements. Cooling tower tip unit contains tubular elements from thermoplastic material with latticed wall folded in layers parallel to each other, wherein at ends tubular elements are welded to each other, tubular elements are made with triangular cross section and between each layer of tubular elements strip from thermoplastic material is laid across tubular elements along each of their ends, welded to tubular elements in places of their contact with strip, wherein during welding melting tubular elements end sections and strips laid between them and forming unit solid end walls, and cavities of each of tubular elements and inter-tube space is filled with heat-mass exchange additional elements. Heat and mass exchange additional elements are made in form of cylindrical ring, on side, inner and outer surfaces of which screw thread in opposite directions is made, or in form of ball on surface of which semi-spherical shape through bores are made, or in form of ring, on outer surface of which screw surface is made according to plated screw type, or in form of, at least, three-bladed propeller.

EFFECT: technical result is uniformity of heat-mass exchange and, consequently, increasing of sprinkler cooling capacity.
