A roll bond heat pipe (RBHP) is very promising in the cooling of electronic
equipment such as notebook computers. This study presents prediction data
on maximum capillary limit obtained for the RBHP with 7.8 mm wide now chann
el. Further, experimental study has been conducted to show the difference b
etween the highest and lowest temperatures on the RBHP. These data determin
e the optimum working fluid charge volume and number of capillary loops for
the RBHP.
