Note:
The present authors have developed high-performance and very compact heat sinks of both pin-fin and plate-fin types for air cooling, and experimentally studied their heat transfer and pressure drop characteristics. The present heat sinks with fin pitch of 0.4-2.1 mm and thickness of 0.2-1.0 mm have excellent cooling performance per unit heat sink volume of three to ten times as large as commercial heat sinks. The correlation of the Colburn j-factor/Fanning friction factor vs the Reynolds number for the present heat sinks was found to be very close to that of conventional large-size heat exchangers in spite of the heat sink's extreme compactness and leading edge effect.
