ABSTRACT:
Temperature variation among electronic apparatuses installed in the data center is reduced, enhancement in reliability of the electronic apparatuses, and increase in service life are achieved, and efficient cooling of an electronic apparatus group is realized. Further, an electronic apparatus with low noise is provided. A front cover is provided on a front surface of an electronic apparatus, and a back cover is provided on a rear surface of it. A supplied air opening is formed at a lower side of the front cover, and an exhaust air opening is formed at an upper side of the back cover. The supplied air opening is connected to a blowing in opening from below the floor level, and the exhaust air opening is connected to a ceiling air duct. The ceiling air duct is provided with a heat exchanger, and indirect heat exchange is performed with external air.
