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.

摘要： Apparatus and method are provided for two-phase dielectric cooling of an electronic device. The apparatus includes a coolant flow path, a vapor condenser and one or more vapor fans. The coolant flow path is in fluid communication with the electronic device, where liquid dielectric coolant within the flow path vaporizes upon contacting the electronic device, forming dielectric coolant vapor, and thereby facilitating cooling of the electronic device. The vapor condenser is also in fluid communication with the coolant flow path and facilitates condensate formation from the dielectric coolant vapor. The one or more vapor fans are disposed within the flow path to actively move dielectric coolant vapor into contact with the vapor condenser, and thereby enhance cooling of the electronic device by facilitating coolant condensate formation and thus recirculation of the coolant condensate as liquid dielectric coolant.
