Abstract: The present disclosure relates to a device for exchange of energy and/or mass transfer between fluid flows, which device comprises a first fluid inlet (3a), a first fluid outlet (3c), a second fluid inlet (5a), a second fluid outlet (5c), a plurality of first channel layers (3) connecting the first fluid inlet (3a) with the first fluid outlet (3c), and a plurality of second channel layers (5) connecting the second fluid inlet (5a) with the second fluid outlet (5c), wherein the plurality of first channel layers (3) and the plurality of second channel layers (5) are arranged in a stacked manner forming stacked fluid channels (2), wherein at least some of the first channel layers (3) are in physical contact with a respective second channel layer (5) thereby forming channel pairs, wherein the channel pairs are spaced apart from each other, whereby cross-current channels (7) are formed therebetween, extending from one lateral side (9) of the stacked fluid channels (2) to the opposite lateral side (11) of the stack

Abstract: The present invention relates to a method of producing multiple channels for use in a device for exchange of solutes between at least two fluid flows. The invention further relates to such a device. At least a first and a second sheet are comprised. The method comprises the steps of providing at least one of the first and second sheets with at least one profiled surface and joining the first and second sheets together with the profiled surfaces facing against each other. Channels are formed by the shape of the profiled surfaces.

Abstract: The present disclosure relates to a sheet (1) for exchange of heat and/or mass transfer between fluid flows, which sheet (1) is provided with corrugations defining open channels (3, 5),wherein every other open channel (3) is a corrugated open channel (3), wherein a cross-section of every corrugated open channel (3) has two channel end points(3a, 3b), and two peaks (3c, 3d) and a valley floor (3e) between the two channel end points(3a, 3b), wherein the two channel end points (3a, 3b) of a corrugated open channel (3) define the mouth of that corrugated open channel (3), wherein the remaining open channels that are intermediate each pair of corrugated open channel (3) are intermediate open channels (5), wherein corrugated open channels (3) and intermediate open channels (5) have mouths in opposite directions. A device comprising such a sheet and a method of manufacturing the sheet is also disclosed herein.
