Systems and assemblies for cooling server racks

A system for cooling server racks comprising:

• a first row of server rack enclosure sub-assemblies, the first row of server rack enclosure sub-assemblies including a plurality of first server rack enclosure sub-assemblies configured to receive at least one first server rack configured to support at least one first server, the first row of server rack enclosure sub-assemblies defining a front portion with respect to the at least one first server rack and a rear portion with respect to the at least one first server rack;
• a second row of server rack enclosure sub-assemblies, the second row of server rack enclosure sub-assemblies including a plurality of second server rack enclosure sub-assemblies configured to receive at least one second server rack configured to support at least one second server, the second row of server rack enclosure sub-assemblies defining a front portion with respect to the at least one second server rack and a rear portion with respect to the at least one second server rack, the rear portion of the second row of server rack enclosure sub-assemblies facing the rear portion of the first row of server rack enclosure sub-assemblies and disposed in spaced relation to one another;
• a central ceiling coupled to the rear portion of the second row of server rack enclosure sub-assemblies and the rear portion of the first row of server rack enclosure sub-assemblies and extending therebetween, the central ceiling, the first row of server rack enclosure sub-assemblies, and the second row of server rack enclosure sub-assemblies defining a confined hot aisle;
• a first cooling sub-assembly disposed above the central ceiling and in thermal communication with the confined hot aisle, the first cooling sub-assembly comprising a structure configured to receive at least one first heat exchange member for exchanging heat between a first fluid flowing through the at least one first heat exchange member and a second fluid flowing through the confined hot aisle and removes the heat from the first and second server racks of the first and second rows of server rack enclosure sub-assemblies, respectively, the at least one first heat exchanger member offset from a central portion of the central ceiling towards one of the at least one first server rack and the at least one second server rack of a first pair of at least one first server rack and at least one second server rack, wherein the first cooling sub-assembly includes a first forced convection member operably coupled thereto and in fluid communication with the confined hot aisle, the first forced convection member disposed adjacent to one of the first row of server rack enclosure sub-assemblies and the second row of server rack enclosure sub-assemblies, wherein the first second fluid flows through the confined hot aisle, through the at least one first heat exchange member, and out of the confined hot above the central ceiling;
• a second cooling sub-assembly disposed above the central ceiling between a second pair of the at least one first server rack and the at least one second server rack and in thermal communication with the confined hot aisle, the second cooling sub-assembly disposed adjacent to the first cooling sub-assembly and including a second forced convection member operably coupled thereto and in fluid communication with the confined hot aisle, the second forced convection member disposed in juxtaposed relation to the first forced convection member such that the second forced convection member is disposed adjacent towards an opposite one of the first row of server rack enclosure sub-assemblies and the second row of server rack enclosure sub-assemblies to which the first forced convection member is disposed such that the first and second forced convection members are disposed in an alternating fashion along a length of the first and second rows of server rack enclosure sub-assemblies;
• and
• a central cooling circuit in thermal communication with the at least one first heat exchange member of the first cooling sub-assembly, the central cooling circuit configured to remove the heat transferred to the first fluid,
• wherein the structure of the first cooling sub-assembly comprises a set of frame members configured and disposed to retain the at least one first heat exchange member, the set of frame members supporting the at least one first heat exchange member to enable the thermal communication with the confined hot aisle for cooling of the first pair of the at least one first server rack and the at least one second server rack,
• wherein the second cooling sub-assembly includes a structure configured to receive at least one second heat exchange member for exchanging heat between the first fluid flowing through the at least one second heat exchange member and the second fluid that flows through the confined hot aisle and removes the heat from the second pair of the at least one first server rack and the at least one second server rack, and
• wherein the first cooling sub-assembly includes a first fluid section in fluid communication with the at least one first heat exchange member, the second cooling sub-assembly includes a second fluid section in fluid communication with the at least one second heat exchange member, the first and second fluid sections disposed at the central portion of the central ceiling such that the at least one first heat exchange member is disposed adjacent to the first fluid section, the at least one second heat exchange member is disposed adjacent the second fluid section, and the at least one second heat exchange member is offset from the central portion of the central ceiling towards the opposite one of the at least one first server rack and the at least one second server rack of the first pair of at least one first and second server racks adjacent to where the at least one first heat exchange member is disposed such that the at least one first heat exchange member and the at least one second heat exchange member are disposed in an alternating fashion.
