Estimating the term…
A contact body or evaporative heat and mass exchanger packing composed of a plurality of side-by-side thin sheets interlocked with one another. The sheets are grooved with a serpentine-like, continuously-variable, cross section form to produce a plurality of liquid and gas channels between the sheets. The sheets have integrally-formed knobs and sockets specifically located to provide up-spaced alternate sheet support without utilizing adhesives of any type. The sheets are preferably composed of a thermoplastic material of any desired length, being continuously pressure-vacuum formed from long sheet rolls. The groove crests abut adjacent sheets apices at continuously-variable spacings of both greater and lesser dimension than the basic edge spacing of the serpentine grooves. The flat crests or apices of grooves are also infinitely variable in width dimension while maintaining a constant sidewall groove angle. The individual sheets are rotatably oriented to provide ideal bottom edge alternate sheet displacement for enhancing fluid flow.
Surface-type heat and mass exchanger fill packing assembly having a top, bottom and side edges for use in an evaporative heat and mass transfer apparatus for producing interaction between a liquid and a gas, said assemably being composed of continuously curved or serpentine-grooved, spaced vertically aligned sheets forming passageways having valleys and ridges formed by said grooves extending in a generally continuously curved, sinusoidal or serpentine path fr.COPYRGT.m edge to edge of said sheets, the groove width at a ridge or valley constantly varying in width from edge to edge of the sheet along the groove, and the entrance angle for liquid at the one edge and gas at the opposite edge of the fill, being the angle of the groove relative to the perpendicular, is maintained nearest to said perpendicular, and where the groove side wall angle relative to the perpendicular to the plane of said fill is constant at any position on said fill, said passageways providing space and surface for liquid and gas interaction, the sheets having the ridges of adjacent sheet grooves forming variable-angle isosceles angular relationship with one another.
