<p>PROBLEM TO BE SOLVED: To enable reduction of the temperature of condensed working fluid and enhancement of cooling performance in a cooling device for cooling a rack type server.SOLUTION: A heat receiving part 12, a heat radiation passage 13, a heat radiation part 15, a feedback passage 14, and the heat receiving part 12 are successively connected in this order to form an annular circulation passage in which working fluid 17 is accommodated. In a cooling device 4 configured so that a check valve 21 is provided at the upstream of the heat receiving part 12, the heat radiation part 15 has a rectangular parallelepiped heat radiation case 16, a partition plate 33 for partitioning the inside of the heat radiation case 16 into right and left parts, and a liquefaction chamber 34 and a cooling water chamber 35 which are disposed at the right and left sides of the partition plate 33. In the liquefaction chamber 34, plural first heat radiation fins 38 each having plural openings 38a are provided in the up-and-down direction of the partition plate 33, and the first heat radiation fins 38 are configured to be inclined upwards from the partition plate 33 side.</p> |
