Abstract

This article presents a numerical and experimental investigation for the single-phase forced laminar convective heat transfer through arrays of micro-channels in micro heat exchangers to be used for cooling power-intensive semiconductor packages, especially the stacked multi-chip modules. In the numerical analysis, a parametric study was carried out for the parameters affecting the efficiency of heat transfer in the flow of coolants through parallel rectangular micro-channels. In the experimental study, the cooling performance of the micro heat exchanger was tested on prototypes of stacked multi-chip modules with difference channel dimensions. The simulation results and the experiment data were acceptably accordant within a wide range of design variations, suggesting the numerical procedure as a useful method for designing the cooling mechanism in stacked multi-chip packages and similar electronic applications.
