Influence de la dérivation de flux d'air sur la performance thermique et la chute de pression des sources chaudes à plaques-ailettes ou à ailettes à picots pour le refroidissement des systèmes électroniques.

Influence of airflow bypass on the thermal performance and pressure drop of plate fin and pin fin heat sinks for electronics cooling.

Auteurs : JONSSON H., PALM B.

Résumé

Tests have been performed in a wind tunnel with eight heat sinks of four different designs including plate fin heat sinks and pin fin heat sinks with circular, elliptical and square cross-sections. The cross-sectional area of the wind tunnel was varied over a wide range and the air velocity was varied from 1 through 4 m/s. A bypass correlation has been developed, describing the deviation in thermal performance and pressure drop for bypass cases as compared to cases with no bypass. The correlation contains a number of parameters which are individual for each heat sink.
