Abstract
An impingement air flow heat sink performance study which considers the effects of geometry, nozzle-to-sink vertical placement, material and Reynolds number has been performed. The experiments consisted of varying the dimensionless nozzle-to-sink vertical distance from 2 to 12 and the Reynolds number from 1 × 104 to 5 × 104. A new carbon composite material manufactured by AlliedSignal was tested and shown to have superior heat transfer characteristics when compared to aluminum. The study also showed that optimal performance is achieved when the nozzle is placed within the dimensionless vertical distance of eight to twelve from the heat sink, and when the Reynolds number lies between 4 × 104 and 5 × 104. Both experimental and analytical estimates of the spreading resistance within the heat sinks tested were obtained.
