Abstract:
1. A method of fabricating a cooling apparatus for facilitating cooling of an electronics rack, the method comprising: associating an air-to-liquid heat exchanger with the electronics rack and disposing the air-to-liquid heat exchanger to cool at least a portion of air passing through the electronics rack, wherein air moves through the electronics rack from an air inlet side to an air outlet side thereof, and the air-to-liquid heat exchanger comprises a plurality of distinct, coolant-carrying tube sections, each coolant-carrying tube section of the plurality of distinct, coolant-carrying tube sections comprising a coolant inlet and a coolant outlet, one of the coolant inlet or the coolant outlet of one coolant-carrying tube section being coupled in fluid communication with a coolant loop to facilitate flow of coolant through the one coolant-carrying tube section; providing a plurality of coolant-cooled structures in thermal contact with a plurality of electronic components of the electronics rack, the plurality of coolant-cooled structures facilitating transfer of heat from the plurality of electronic components to the coolant; and connecting in dedicated fluid communication one coolant-cooled structure of the plurality of coolant-cooled structures and the other of the coolant inlet or the coolant outlet of the one coolant-carrying tube section of the plurality of distinct, coolant-carrying tube sections of the air-to-liquid heat exchanger, the connecting in dedicated fluid communication ensuring flow of coolant directly between the one coolant-carrying tube section of the air-to-liquid heat exchanger and the one coolant-cooled structure of the plurality of coolant-cooled structures.
