Abstract:
A computer system, comprising:an enclosure having at least one intake and at least two exhausts formed therein; at least one computer system device disposed in the enclosure; and a cooling system including at least two coolant flow control assemblies, each flow control assembly positioned substantially adjacent to one of the at least two exhausts of the enclosure, and each coolant flow control assembly including: a pressure creator; and a valve assembly substantially aligned with the pressure creator, the valve assembly comprising first and second ends and first and second hinged members, each member having a first side, the first and second hinged members being operatively coupled to the first and second ends of the valve assembly at the first side of each member; wherein, each pressure creator is configured to create a pressure difference between a coolant pressure outside the enclosure and a coolant pressure inside the enclosure, the pressure difference causing an inward flow of cool coolant from outside the enclosure through the intake to the at least one computer system device and causing heated coolant exposed to the at least one computer system device to flow outside the enclosure through the at least two exhausts, wherein the members of the valve assembly close if one of the pressure creators of the at least two flow control assemblies fails to maintain the pressure difference, the closed members preventing an inward flow of heated coolant from outside the enclosure adjacent to the exhaust that is substantially adjacent to the failed pressure creator of the at least two coolant flow control assemblies.
