Revising the goals and means for the base-to-air cooling stage for semiconductor heat-removal-experiments and their results

Abstract

The development of simulation methods and data reduction for heat sink experiments are the purpose of this work. The study dealt with an experimental investigation of semiconductor heat sink performance characteristics. The heat sinks were constructed of aluminum and consisted of an array of staggered pin fins and longitudinal fins. The cooling fluid was air and the experiments were conducted with a porous medium Reynolds number ranging from 400 to 17000. A number of data reduction parameters and procedures were developed using a scaling heterogeneous formulation by volume averaging theory (VAT). We analysed the basic homogeneous heat transfer performance features and have shown the insolvency of using conventional Nusselt numbers, homogeneous heat transfer rate and effectiveness parameters. We introduced and analysed heterogeneous upper scale heat transfer characteristics, and provided comparisons with other studies.
