Two-phase liquid immersion cooling of computers is becoming an increasingly favorable heat removal strategy. A re-entrant cavity heat sink has been developed to address these needs. In confined situations, the vapor generated moves through the channel formed between adjacent substrates. Bubble transport is therefore affected by the channel width. Saturated pool boiling results are presented and discussed for vertically oriented channels of widths ranging from 0.1 cm to 0.6 cm to cover typical values likely to be encountered. The heat source was a deposited aluminum thin film heater of size 0.9 cm by 0.9 cm. The cavities were laid out over a 2.5 cm by 2.5 cm area. Testing was carried out in FC-72, It was found that the presence of a parallel plate affected the heat transfer performance adversely.ETX
