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

The development of simulation methods and data reduction for heat sink expe riments are the purpose for this work. The study dealt with an experimental investigation of semiconductor heat sinks performance characteristics. The heat sinks were constructed of aluminum and consisted of an arrays of stag gered pin fins and longitudinal fins. The cooling fluid was an air and the experiments were conducted with a porous medium Reynolds number ranging fro m 400 to 17000. A number of data reduction parameters and procedures were d eveloped using scaling heterogeneous formulation by volume averaging theory (VAT). Analysed the basic homogeneous heat transfer performance features a nd shown insolvency of using conventional Nusselt numbers, homogeneous heat transfer rate and effectiveness parameter. Introduced and analysed heterog eneous upper scale heat transfer characteristics. Provided comparisons with other studies.
