EP2498024A3

Cooling system for electronic equipment

Abstract

An electronic device which is required to perform a precise operation with a heat generation amount from itself being large, such as a computer and a server, can be efficiently cooled at low running cost. Server rooms (14A, 14B) in which a plurality of servers (28) are placed, an evaporator (34) which is provided close to each of the servers (28), and cools exhaust air from the server (28) by vaporizing a refrigerant with heat generating from the server (28), a cooling tower (38) which is provided at a place higher than the evaporator (34), cools the refrigerant by outside air and water sprinkling, and condenses the vaporized refrigerant, and a circulation line (40) in which the refrigerant naturally circulates between the evaporator (34) and the cooling tower (38).
