ABSTRACT:
A multi-channel device fabrication process and multi-channel devices made therefrom wherein two ribbons of sheet material edge webs and, optionally, additional webs and/or support members are secured to a ribbon of sheet material base web. The resulting partial laminate is separated into subassemblies, each subassembly comprising a base and two edge strips and, optionally, additional strips which cooperate to define a plurality of open channels with, optionally, support members. A plurality of subassemblies may stacked together with an end plate to form a complete stack, the edges of each subassembly being attached together to form a complete unit. One or more headers or manifolds may be attached to the outside of the complete unit to provide combined fluid inlet to, and egress from, the unit.
