Abstract

Heat dissipation in electronic circuits is important to maintain their reliability and functionality. In this work micro-channel based bio-inspired flow field models are proposed and numerically analyzed. The proposed flow fields have single to four, inlet-outlet pairs. COMSOL is used to do the numerical analysis. Conjugate heat transfer analysis is done on the quarter sectional models, utilizing bi-axial symmetry of the flow fields to reduce computational cost. Constant heat flux is applied to the base of the proposed heat sinks. The results show that, the thermal and hydraulic resistances of the proposed models are lower than traditional micro-channel arrays. The four inlet-outlet pairs, model shows a thermal resistance of 0.121 to 0.158 C/W at constant Re inlet condition, achieved with a pumping power of 0.102-0.126W. Two and four, inlet-outlet pair models with aspect ratio 8.6 have a thermal resistance of 0.069 and 0.067 C/W, for pumping powers 2.078 and 4.365W respectively. The pressure drop of the proposed models is lower than conventional microchannel arrays.
