Micro channel heat sink with embedded pin-fin structures

The dissipation of heat with the help of micro channel heat sink and micro pin-fin fin heat sink has been a topic of interest for many researchers over a decade. The comparison between these two heat sink and the advantage and disadvantages of one over the other has been studied by researchers. In this paper, the authors are trying to study the effect of introducing pin-fin structures inside the micro channel heat sink. A FOM term is introduced in the paper to evaluate the overall performance of the ordinary micro channel heat sink and the micro channel heat sink with pin-fin structures embedded in it. The effect of introducing different shapes of pin-fin structures inside the micro channel is also studied in the paper. The study results showed that there is a huge increase in the overall performance of the micro channel heat sink by introducing pin-fin structures inside the channel, but the study also showed that the effect of introducing different shapes of pin-fin structures inside the channel is negligible.
