Vapor Chamber

Vapor chamber is similar to heat pipe in flat copper plate form, filled with working fluid. It is vacuumed and then injected with just enough liquid (e.g. water) to wet the wick. Liquid changes to vapor phase bringing the heat from evaporation section in all directions to cooling zone (condenser), followed by the capillary force of wick brings working fluid back to evaporation section and continue the cycle.
