<p><P>PROBLEM TO BE SOLVED: To provide a liquid cooling system using a plurality of coolant temperature controlling units (CCUs) such that a function is not stopped because of the trouble of a heat exchanger, a control valve, the loss of a cooling water source or the like. <P>SOLUTION: Each CCU 310 of a plurality of the coolant temperature controlling units (CCU) out of a plurality of electronic racks that should be cooled is coupled to one electronics rack 330 that is different and incidental to, and is provided with the heat exchanger, first cooling loops provided with the control valve and second cooling loops 315, 316. The first cooling loops receive an objective cooling facility coolant from the source, and at least a part of the coolant is allowed to pass through the heat exchanger through the control valve. The second cooling loops 315, 316 supply an objective system coolant to the incidental electronics rack 330, and in the heat exchanger, the heat is diffused in the objective cooling facility coolant in the first cooling loops from the electronics rack 330. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
