ABSTRACT:
A cooling apparatus for an electronic system, includes a coolant tank, main pumps, heat exchangers, a common supplementary pump, and supplementary check valves. The coolant tank temporarily stores a coolant. The main pumps are respectively arranged in a plurality of heat generators in the electronic system, and the main pumps supply the coolant from the coolant tank to the heat generators. The heat exchangers cool the coolant from each of the heat generators and return the coolant to the coolant tank. The common supplementary pump is operated when any one of the main pumps has failed and supplies the coolant from the coolant tank. Each of the supplementary check valves has an upstream side connected to an outlet port of the supplementary pump and downstream sides connected to outlet ports of the main pumps. Each of the supplementary check valves is opened when a pressure difference between the upstream side and the downstream side of each of the supplementary check valves is larger than a predetermined value.
