Auteurs : MISALE M., GUGLIELMINI G., FROGHERI M.

Résumé

Heat transfer measurements were taken during nucleate pool boiling of a saturated liquid (FC-72), utilized for thermal control of electronic components, from finned surfaces placed in a horizontal channel. The fins were 3 or 6 mm high. Starting from a uniform configuration, for which the width spacing of the spines was 0.4 mm, non-uniform surfaces were obtained by regularly removing some rows of spines. The effect of channel width (20 mm down to 0.5 mm) and spines distribution was analyzed. The experimental data were also compared with those obtained in the case of an unconfined extended surface.
