Claim of US Patent No. 10,716,236

1. A data center cooling system, comprising:a first module comprising a warm air plenum positionable to receive an airflow from one or more rows of racks that support a plurality of heat-generating electronic devices, the warm air plenum comprising a warmed air inlet adjacent an open side of the one or more rows of racks and a warmed air outlet adjacent a data center volume above the one or more rows of racks, the warmed air inlet comprising a perimeter edge in contact with a top portion of a first row of the one or more rows of racks and a top portion of a second row of the one or more rows of racks that is positioned parallel to and opposite a warm air aisle defined between the first and second rows of racks to form a barrier between the top portions of the first and second rows of racks and the first module, where the barrier substantially prevents airflow from a portion of a human-occupiable workspace of the data center adjacent open front sides of the one or more racks to the warm air inlet;
a second module positionable in the data center volume above the one or more rows of racks and comprising:
a horizontal bottom panel;
a plurality of vertical side panels coupled to the horizontal bottom panel;
at least one cooling module vertically mounted adjacent at least one of the vertical side panels; and
at least one fan, the at least one fan positioned to circulate a warmed airflow from the one or more rows of racks, through the warmed air plenum, into the data center volume, through the at least one cooling module to cool the warmed airflow, and into the human-occupiable workspace of the data center adjacent the one or more rows of racks; and
an airflow partition mountable in the data center volume above the one or more rows of racks and adjustable to interrupt the warmed airflow between the warmed air plenum and the second module,
wherein the warmed air outlet defines an opening in a ceiling panel that extends horizontally over and above the first and second rows of racks such that the warm air plenum is open to the data center volume at or above the ceiling panel, and the at least one cooling module of the second module is disposed adjacent to the opening in the ceiling panel, and the at least one fan is positioned to circulate a cooled airflow from the at least one cooling module into the human-occupiable workspace of the data center and through the open front sides of the one or more rows of racks.
