Air-Cooled Heat Sink for Electronic Equipment. Heat Transfer Characteristics of Inclined Strip Fins and a Multiflow Air Duct System.

A high-performance air cooling system unifying the heated plates temperature distribution is investigated. The plates are arranged in series and cooled by serial air flow. As a result of the investigations, fins with projections and a multiflow air duct system have been developed by the authors. The fins have inclined rows of minute projections on the surface and can improve the cooling performance. The multiflow air duct system can promote unification of the plate temperature distribution bypassing fresh, low-temperature air onto the lower plate.
