ABSTRACT:
A heat sink is built including a three dimensional array of cylindrical openings for air to flow through instead of fins. By having a larger surface area than heat sinks with fins, this high surface area heat sink results in increased heat transfer to the surrounding air than a similarly sized heat sink with fins. Heat sinks including an array of cylindrical openings may be manufactured through extrusion, stamping, and other common techniques.
