Patent ID: 10813243

Abstract:
It is impossible to avoid the increase in device cost and maintenance cost in order to cool a plurality of heat sources efficiently using a natural-circulation type phase-change cooling device; therefore, a phase-change cooling device according to an exemplary aspect of the present invention includes a plurality of heat receiving units configured to hold respectively refrigerant receiving heat from a plurality of heat sources; a condensing unit configured to generate refrigerant liquid by condensing and liquefying refrigerant vapor of the refrigerant evaporated in the heat receiving units; a refrigerant vapor transport structure connecting the heat receiving units to the condensing unit and configured to transport the refrigerant vapor; and a refrigerant liquid transport structure connecting the heat receiving units to the condensing unit and configured to transport the refrigerant liquid, wherein the refrigerant liquid transport structure includes a main-liquid-pipe connected to the condensing unit, a refrigerant liquid reservoir connected to the main-liquid-pipe and configured to store the refrigerant liquid, and a plurality of sub-liquid-pipes respectively connecting the refrigerant liquid reservoir to the plurality of heat receiving units.
