Abstract:
1. A cooling apparatus for an electronics rack, the cooling apparatus comprising: an air-to-liquid heat exchanger associated with the electronics rack and disposed 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, at least 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; at least one coolant-cooled structure in thermal contact with at least one electronic component of the electronics rack, the at least one coolant-cooled structure facilitating transfer of heat from the at least one electronic component to the coolant; and a tube connecting in fluid communication one coolant-cooled structure of the at least one coolant-cooled structure, 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 tube facilitating 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 at least one coolant-cooled structure.
