Subtractive design: A novel approach to heatsink improvement

摘要

Typical Heatsink design includes base and fin thickness, fin height, and fin gap optimization. In situations where material cost or mass of the heat sink are also a design priority further optimization with respect to mass removal can be significant. This paper discusses a method to further improve a heat sink topology by the systematic removal of heat sink mass where the Thermal BottleNeck (BN) Number was found to be lowest.
