PACKING FOR HEAT-EXCHANGE APPARATUS Russian patent published in 2006 - IPC F28F25/08 

FIELD: heat power engineering, metallurgy, oil refining, petroleum chemistry and other branches of industry using circulating water supply, applicable for enhancing the efficiency of water cooling in operation as a sprinkler and for reduction of its irrevocable loss in operation as a water catcher in cooling towers.

SUBSTANCE: the packing for a heat-exchange apparatus has units with long-sized bulky components with a lattice shell enveloped by closed surface contours and fastened in the units by inner frameworks formed by fixing components passing through the bulky components. The mentioned fixing components of the inner frameworks are made in the form of a single flexible core or pipe, or belt repeatedly alternating the through penetration of the unit with bending through its closed surface of the stiffness profile, the ratio of the radius of bending to the largest dimension of the profile of the bulky component equals 0.1-10, and the beginning and end of the fixing component are fastened on the closed surface contour of the unit stiffness. At such a structure of the units their assembly is considerably simplified due to the use of a single flexible fixing component, a strong coupling between the bulky components with the lattice shell, fixing components of the inner frameworks and closed surface contours of stiffness is provided. The availability of bendings between the fixing components of the inner frameworks and the closed surface contours of stiffness forms bulky, flexible complexes in the units uniformly redistributing the arising external mechanical loads between themselves. The bulky components with the lattice shell are fully unloaded and not subjected to deformation and shrinkage, and reflect and crush the water splashes in operation as a sprinkler, effectively catch the water drops carrier away by the air flow in operation as a water catcher.

EFFECT: enhanced efficiency of packing operation by 15-20%.
