Claim of US Patent No. 10,433,466

1. An apparatus, comprising:a prefabricated infrastructure module (PIM) for mixing configured to provide air handling for an information handling system in an enclosed space, the prefabricated infrastructure module (PIM) comprising:
an interior intake opening configured to receive warm air from a warm aisle of the enclosed space;
an exterior intake opening configured to receive air from an exterior environment;
a mixing aisle configured to receive air from the interior intake opening and from the exterior intake opening and further configured to allow mixing of air from the warm aisle and air from the exterior environment;
a recirculation opening coupled to the mixing aisle and configured to output mixed air from the mixing aisle for recirculation through the enclosed space to cool the information handling system; and
an exhaust opening coupled to the mixing aisle and configured to allow exhaust of air from the mixing aisle to the exterior environment,
wherein the PIM comprises multiple levels, and wherein the mixing aisle traverses substantially an entire length of the PIM multiple times while passing through the multiple levels,
wherein a first portion of the mixing aisle traverses substantially the entire length of the PIM at a first level of the multiple levels and a second portion of the mixing aisle traverses substantially the entire length of the PIM at a second lower level of the multiple levels, and wherein the first portion and the second portion of the mixing aisle are separated by a divider traversing at least a portion of the length of the PIM,
and wherein the mixing aisle is configured to channel air from the exterior intake through the first portion of the mixing aisle and the second portion of the mixing aisle, around the divider, to the recirculation opening.
