The phase change radiator is an integrated plate structure with a hollow cavity, and phase change working media are filled in the cavity and are in a negative pressure state. When heat flow is conducted to an evaporation zone of the phase-change radiator from a heat source, the phase-change working medium in the cavity starts to generate a liquid phase vaporization phenomenon at a specific temperature under a vacuum condition, at the moment, the phase-change working medium can absorb heat energy and quickly vaporize, vapor of a vapor phase can fill the whole cavity under the condition, and the vapor phase moves to a condensation section to be cooled and liquefied and then flows back to the evaporation section under the action of gravity or capillary force to form gas-liquid circulation.
