Abstract
A pin fin heat sink having mixed geometry pin fin configurations is presented. The mixed geometry pin fin configuration are designed to optimize the positive attributes of each individual pin fin geometry to provide a low cost overall system and provide better system performance in high flow rate systems. In an exemplary embodiment, the pin fin heat sink comprises a base surface having a plurality of pin fins perpendicular to and protruding therefrom. The plurality of pin fins actually comprises a plurality of pin fins having a first configuration and a plurality of pin fins having a second configuration. The second configuration pin fins are intended to streamline any turbulence created by the first configuration pin fins which are located upstream of the second configuration pin fins. Preferably, the first configuration comprises substantially circular shaped pin fins and the second configuration comprises substantially elliptical shaped pin fins.
