Abstract: A monolithic vapor chamber heat dissipating device uses a phase change liquid and one or more wicks to dissipate heat from a heat-generating system. The phase change liquid and one or more wicks may be directly coupled to the heat-generating system, or may be coupled to an intermediate evaporator substrate. The phase change liquid vaporizes as it absorbs heat from the heat-generating system. When the vapor rises and encounters a condenser substrate, the vapor condenses and transfers the heat to the condenser substrate. The condensed vapor is drawn by gravity and the one or more wicks to the phase change liquid coupled to the heat-generating system.
