Abstract :
High-performance inversely trapezoidal heat sinks for multi-chip modules under forced air cooling have been developed by means of thermal simulation. Heat sink specifications were assumed as follows: 60 mm (length)×60 mm (width)×17 mm (height) with less than 0.8°C/W thermal resistance at 3 m/s air velocity. A simple thermal simulation method for a heat sink was first developed to perform thermal flow analysis in the air and heat transfer analysis. The accuracy of this simulation was within ±20%, and a novel plate-format heat sink with inversely trapezoidal fins has been successfully designed using this simulation
