Patent ID: 8573289

Claim:
A Heat Exchanger device comprising: a shell; and a three-dimensional ordered microstructure material comprising a plurality of intersecting truss elements within the shell; wherein said truss elements comprise; a plurality of first truss elements defined by a plurality of first self-propagating polymer waveguides and extending along a first direction; a plurality of second truss elements defined by a plurality of second self-propagating polymer waveguides and extending along a second direction; and a plurality of third truss elements defined by a plurality of third self-propagating polymer waveguides and extending along a third direction; wherein said truss elements interpenetrate each other at a plurality of nodes to form a continuous material; wherein the three-dimensional ordered microstructure material has a node to node spacing between 10 micrometers and 5 millimeters; and said plurality of truss elements have a diameter between 1 micrometer and 5 millimeters.
