Many new concepts in designing and fabricating thermal management materials TMMs were explored to make an efficient meso-scale heat exchanger. The proposed TMMs have multi-functionality that combines structural material with cooling components by utilizing embedded microstructures in a miniature-sized body to enhance heat and mass transfer, chemical reactions etc. Mesomachines are expected to provide a number of important functions where a premium is placed on mobility, compactness, or point application. More specifically, we are designing and fabricating micro-textured Functionally Graded Material FGM and micro-configured for cooling channels medium to compensate thermal gradient loading as a result of heat transfer into a cooling fluid circulating in the network of channels and manifolds. Previous work Kwon et al., 1994, Kwon and Dharan, 1995 attest to the motivation for such medium. For the complicated structure with cooling channels such as our heat exchanger, finite element FE modeling provides the flexibility needed to design an optimal gradiency in properties by analyzing not only the magnitude of heat transfer into the fluid flow but also the integrity of the structure.
