Experimental verification of a model for the optimization of pin fin heatsinks

Abstract

An analytical model for the optimization of pin fin heatsinks was developed. The model is based on correlations of flow resistance and heat transfer from studies of tube bank heat exchangers. Experimental verification of the model shows that, with some minor modification to the heat transfer correlations, it reasonably represents heat transfer trends. Flow resistance trends are under-predicted for both inline and staggered pin arrangements. Even with these limitations this tool is useful for the optimization and pin arrangement selection of pin fin heatsinks.
