Abstract:
A microchannel mass exchanger, comprising a laminate bonded from sheets comprising:(a) an inner sheet having a solid margin around a circumference, said solid margin defining a slot through a thickness of said inner sheet; (b) at least one outer sheet having at least two header holes positioned within said solid margin and positioned at opposite ends of a slot length; wherein the inner sheet is adjacent to the at least one outer sheet; wherein the solid margin sealably spaces the at least one outer sheet; wherein the at least one outer sheet defines at least one longitudinal wall of a flow channel having a length parallel to a sheet length, such that a fluid can enter through one of said header holes into said slot to flow in a direction parallel or longitudinal to the length of said flow channel; (c) a fluid within the flow channel; (d) a mass transfer medium within the solid margin and on or integral with at least one of said outer sheet or an end block; wherein said microchannel mass exchanger has an outer surface defined by a plurality of edge thicknesses of inner and outer sheets, said outer surface proximate a thermal load so that said thermal load is transmitted via conduction through said outer surface and also transmitted via convection between said inner sheet and said at least one outer sheet and said fluid.
