COOLING DEVICE AND DATA CENTER PROVIDED WITH SAME

摘要

A cooling device has a circulation passage that annularly connects heat receiving part, heat radiation passage, heat radiation part, and feedback passage in order, and working fluid housed in the circulation passage, and check valve provided on an upstream side of heat receiving part. Heat radiation part has a liquefying chamber and a cooling water chamber separated by a partition plate. The liquefying chamber has a first connection part connected to heat radiation passage at an upper part of liquefying chamber, and a second connection part connected to feedback passage at a lower part of liquefying chamber, and has a plurality of first heat radiation fins fixed to the partition plate, and having a plurality of openings or cutouts. The cooling water chamber has a cooling water inlet, a cooling water outlet, and a plurality of second heat radiation fins that separate a passage from the cooling water inlet to the cooling water outlet into a plurality of parallel passages.
