A flexible mesoscopic heat exchanger is provided by the invention. The heat exchanger
of the invention includes uniform microchannels for fluid flow. Separate header
and channel layers include microchannels for fluid flow and heat exchange. A layered
structure with channels aligned in multiple orientations in the layers permits
the use of a flexible material without channel sagging and provides uniform flows.
In a preferred embodiment, layers are heat sealed, e.g., by a preferred lamination
fabrication process.
