A method and apparatus for pool boiling includes introducing a fluid into a chamber of a housing which has one or more protruding features. One or more diverters extend at least partially across the one or more protruding features in the chamber. One or more bubbles are formed in the fluid in the chamber as a result of bubble nucleation. At least one of growth and motion of the one or more of the bubbles are diverted with the one or more diverters to generate additional localized motion of the fluid along at least one of the one or more protruding features and other surfaces in the chamber of the housing to at least of transfer additional heat to the liquid and increase the critical heal flux limit.

Passive two phase heat transfer systems

A boiling heat transfer unit includes a substrate having a heat exchange region including a plurality of nucleating regions adjacent to feeder channels, wherein adjacent nucleating regions are separated by the feeder channels at a distance whereby vapor formed in the nucleating regions is moved away from the nucleating regions influencing liquid flow through the feeder channels towards the nucleating regions thereby establishing continuous self-sustaining separate vapor and liquid pathways increasing heat transfer due to developing region heat transfer in the feeder channels and enhancing overall boiling performance.
