Microfabricated heat sinks and heat exchangers are of increasing interest for numerous applications, including electronics cooling, due to the enhancement of convective heat transfer as well as an increase in surface area per unit volume with reduction in characteristic length scale. High cost per unit volume and limitations on device thickness severely constrain the applicability of heat transfer devices fabricated using traditional microfabrication techniques. HRL has developed a novel 3-D microfabrication method utilizing self-propagating photopolymer waveguides to form micro-scale truss architectures over large areas. I will present experimental and computational investigations into the fluid dynamics and heat transfer properties of these micro-scale trusses; multiobjective optimization guided materials architecture design; and newly enabled heat transfer devices, including cold plates and heat exchangers.
