Abstract
A lamina stack for a two-pass evaporator composed of laminae for converting two media mass streams from a liquid state into a gaseous state, comprises at least two laminae. Structures comprising recesses and raised regions on a first media lamina form a first media chamber perfused by one of the media mass streams. The structures on a second media lamina form a second media chamber perfused by the other one of the media mass streams. The at least two of the laminae can be supplied with thermal energy. Both media laminae have comparable structures, with at least a majority of the recesses in the one of the media laminae being disposed above or below the raised regions of the respective other media lamina.
