Abstract
A cooling apparatus for use with an electronic system provides an uninterrupted operation capability. A pump supplies a cooling liquid to a liquid-cooled electronic system. The pump is controlled by a controller that also controls a three way valve for controlling the operation of a three-way valve for regulating the flow quantity of the cooling liquid flowing into a heat exchanger for cooling the cooling liquid. The cooling apparatus has a plurality of cooling control units. While one cooling control unit is in operation, the other is in the standby state. If one cooling control unit fails, the standby cooling control unit is automatically put in the operating state, thereby allowing servicing of the failing unit without interrupting the operation of the liquid-cooled electronic system and the cooling apparatus.
