PRESSURE DROP AND HEAT TRANSFER IN AIRFLOW COOLED FINNED HEAT SINKS USING CORRELATIONS
|
| |
|
Summary :
|
|
ABSTRACT. A NETWORK FLOW MODEL WAS DEVELOPED TO CALCULATE THE PRESSURE DROP ACROSS A FINNED PARALLEL PLATE HEAT SINK. AIRFLOW WAS ASSUMED AT EITHER LAMINAR OR TURBULENT REGIME IN THE FIN CHANNELS. THE PRESSURE DROP INCLUDED VISCOUS FRICTION AND THE CONTRACTION AND EXPANSION LOSSES OF THE FLOW. HEAT TRANSFER CORRELATIONS WERE ADAPTED FROM THE LITERATURE. A COMPARISON WAS MADE WITH PUBLISHED DATA FOR THE AIRFLOW VOLUMETRIC FLOW RATE ACROSS A HEAT SINK AND THE ASSOCIATED THERMAL RESISTANCE. |
