In a natural circulation-type phase-change cooling device (1000), cooling performance is reduced when the number of heat generation sources to be cooled increases. Accordingly, this phase-change cooling device (1000) is provided with: a plurality of heat reception units (1010) respectively having, accommodated therein, a refrigerant which receives heat from a plurality of heat generation sources; a condensation unit (1020) which condenses and liquefies a refrigerant vapour obtained as a result of the vaporization of the refrigerant in the heat reception units (1010), to generate a refrigerant liquid; a refrigerant-vapour conveyance structure (1100, 1101) which connects the heat reception units (1010) and the condensation unit (1020), and conveys the refrigerant vapour; and a refrigerant-liquid conveyance structure (1200) which connects the heat reception units (1010) and the condensation unit (1020), and conveys the refrigerant liquid. The refrigerant-vapour conveyance structure (1100, 1101) is provided with: a plurality of secondary vapour tubes (1110) which are respectively connected to the plurality of heat reception units (1010); a vapour merging unit (1120, 2100, 3100, 3200) which is connected to the plurality of secondary vapour tubes (1110), and in which the refrigerant vapour merges; and a main vapour tube (1130, 3130) which connects the vapour merging unit (1120, 2100, 3100, 3200) and the condensation unit (1020). |
