Heat Sink Optimization through Use of Pin Fins

In a recent blog post, Robert Smith discusses heat sink optimization through the use of pin fins.

“Local heat transfer coefficients are highest when the air first begins to form a boundary layer.  The benefit to lots of pins is that you force the boundary layers to break away often and re-create on the next pin,” Smith said.

The heat sink forms a 3D mesh of pins that cross each other and force mixing of flow. Smith plans to test it against a sample commercial heat sink for chip cooling with very high fin density.
