ABSTRACT:
A high performance, high pin fin density heat sink (10) has mating first and second opposing base members (22, 24) having first and second pin fins (18, 20) extending generally perpendicularly therefrom. The pin fins (18, 20) are generally cylindrical and each bonded into recesses (30, 32) formed on the opposing base member (22, 24). The spaces between nearest adjacent first and second pin fins (18, 20) form narrow fluid passageways (12) having a gas inlet in (14) for communicating with a heat generating body and gas out let end (16).
