摘要： A conduction heat transfer connection is made between a heat source and a heat sink which is flexible so as to adapt to variations in distance between the source and sink and which maintains the required force on the heat source to obtain the required heat transfer across the junction therebetween. The connection consists of a heat conductive metallic foil bundle of sufficient thickness to contact sufficient surface area of the heat source to provide the required heat transfer and of sufficient thinness to be flexible enough to absorb the expansion and contraction due to temperature changes as well as the differences in distance between the heat source and sink and of sufficient length to contact at or near the other end thereof the heat sink.

摘要： An apparatus is provided for cooling an electronics rack, which includes an electronic subsystem across which air passing through the rack flows. A cooling unit provides, via system coolant supply and return manifolds, system coolant in parallel to the electronic subsystem and an air-to-liquid heat exchanger disposed to cool, in normal-mode, air passing through the rack. A controller monitors coolant associated with the cooling unit and automatically transitions the cooling apparatus from normal-mode to failure-mode responsive to detecting a failure of the coolant. In transitioning to failure-mode, multiple isolation valves are employed in switching to a serial flow of system coolant from the electronic subsystem to the heat exchanger for rejecting, via the system coolant, heat from the electronic subsystem to air passing across the heat exchanger.
