The invention relates to a monolithic phase change heat sink. 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 condensedvapor is drawn by gravity and the one or more wicks to the phase change liquid coupled to the heat-generating system. 本公开涉及单片相变散热装置。单片蒸汽室散热装置使用相变液体和个或多个芯体来散发来自发热系统的热量。相变液体和个或多个芯体可以直接耦合到发热系统，或者可以耦合到中间蒸发器基板。相变液体蒸发，因为它从发热系统吸收热量。当蒸汽上升并遇到冷凝器基板时，蒸汽冷凝并将热量传递给冷凝器基板。冷凝的蒸汽通过重力和个或多个芯体被吸引到与发热系统耦合的相变液体。
