Micro-architected materials for heat exchanger applications

摘要

A method of exchanging heat between fluids with a heat Exchanger comprising a three-dimensional ordered microstructure material within a shell. The three-dimensional ordered microstructure material has dimensions that allow for large surface area to volume ratios, between 300 and 15000 m2/m3. Alternatively the three-dimensional ordered microstructure may have an open volume fraction between 0.4 and 0.6. The three-dimensional ordered microstructure may be comprised of hollow truss elements and partially filled with a thermally conductive material or a fluid. The Heat Exchanger has a heat transfer coefficient multiplied by the surface area to volume ratio between 3.7*107 and 7*109 Watts per M3K.

1. A method of exchanging heat between two fluids, the method comprising:
receiving a first fluid in a first input port of a heat exchanger device and receiving a second fluid in a second input port of the heat exchanger device; wherein the heat exchanger device comprises a three-dimensional ordered microstructure material and a shell; wherein said three dimensional ordered microstructure material further comprises a plurality of truss elements intersecting at a plurality of nodes to form a continuous material, 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 the three-dimensional ordered microstructure material has a node to node spacing between 10 micrometers and 5 millimeters; and said plurality of truss elements having a diameter between 1 micrometer and 5 millimeters.
