Abstract

With the miniaturisation of electronic equipment’s, removal of heat generated in the microprocessors has become a great problem for research. Nowadays micro fins are extensively used as heat sinks. Therefore the heat transfer analysis of micro fins is an interesting but yet a limited area of research. This paper extends the heat transfer analysis of micro fins under natural convection. It presents the experimental determination of the effect of fin shape, spacing and height on the Nusselt number. A set of six micro fins, with different shape, height and spacing is tested in a standard experimental setup and the Nusselt number for each microfin is determined. Based on the experimental result a correlation is developed connecting nusselt number as a function of the height to space ratio and the shape coefficient. The correlation is validated with the research results in the literature.
