What is it about?
Vapor chambers are sealed, heat-spreading devices that use phase change (boiling, condensation) to keep sensitive electronics within safe temperature limits. We present a new category of vapor chambers, which do away with porous wicks and offer important advantages over conventional vapor-chamber designs.

Why is it important?
Wickless vapor chambers feature lower thermal resistance to heat flow, a desirable characteristic for high performance. They are thinner than conventional (wick-lined) vapor chambers, thus offering an advantage for high-power electronics, which generate high amounts of heat in confined spaces.
