<p>PROBLEM TO BE SOLVED: To lower a temperature of a condensed working fluid and to enhance cooling capacity, in a cooling device for cooling a rack type server.SOLUTION: A cooling device 4 is configured in such a manner that: an annular circulation path is formed in which a working fluid 17 is stored by connecting a heat receiving part 12, a heat radiation path 13, a heat radiation part 15, a feedback path 14 and the heat receiving 12 sequentially; and in the heat receiving part 12, a check valve 21 is provided at an upstream of the heat receiving part 12. The heat radiation part 15 is configured by: a rectangular parallelepiped-shaped heat radiation case 16; a partition plate 33 for partitioning the inside of the heat radiation case 16 vertically; a liquefaction chamber 34 on the upstream side of the partition plate 33 and a cooling water chamber 35 on the downstream side of the partition plate 33. An upper end of the partition plate 33 is located lower than a lower end of a second connection part 37 to the feedback path 14 provided below the liquefaction chamber 34.</p> |
