Notes:
Numerous methods have recently emerged for fabricating cellular lattice structures withunit cells that can be repeated to create 3D space filling systems with very high interconnected porefractions. These lattice structures possess exceptional mechanical strength resulting in highlyefficient load supporting systems when configured as the cores of sandwich panels. These samestructures also provide interesting possibilities for cross flow heat exchange. In this scenario, heat istransported from a locally heated facesheet through the lattice structure by conduction and isdissipated by a cross flow that propagates through the low flow resistant pore passages. Thecombination of efficient thermal conduction along the lattice trusses and low flow resistance throughthe pore channels results in highly efficient cross flow heat exchange. Recent research is investigatingthe use of hollow truss structures that enable their simultaneous use as heat pipes which significantlyincreases the efficiency of heat transport through the lattice and their mechanical strength. Therelationships between heat transfer, frictional flow losses and topology of the lattice structure arediscussed and opportunities for future developments identified
