摘要

Computational modeling, temperature measurements, and flow visualizations were conducted to investigate the enhancement of combined natural convection, conduction, and radiation heat transfer from a 25.4 mm x25.4 mm discrete heat source in a 127 mm x 127 mm and 41.3 mm high enclosure, using pin-fin heat sinks. The pin-fin array was attached to the heated component, which was flush mounted on the enclosure base. Effects of flow confinement by enclosure walls on heat transfer from the pin-fin heat sink ware found prominent.
