Patent ID: 7283358

Claim:
A cooled electronics system comprising: an electronics rack, the electronics rack having: an air inlet side and an air outlet side, the air inlet and air outside sides respectively enabling ingress and egress of air; at least one electronics drawer; at least one air moving device, the at least one air moving device being capable of causing external air to flow from the air inlet side of the electronics rack, across the at least one electronics drawer to the air outlet side of the electronics rack; an apparatus coupled to the electronics rack for facilitating cooling the electronics rack, the apparatus comprising: an air delivery structure coupled to the electronics rack for delivering air flow at a location external to the electronics rack and in a direction to facilitate mixing thereof with any re-circulating exhausted inlet-to-outlet air flow from the air outlet side of the electronics rack to the air inlet side thereof, wherein the delivered air flow is cooler than the re-circulating exhausted inlet-to-outlet air flow, and wherein mixing of the delivered air flow and the re-circulating air flow facilitates lowering air inlet temperature at a portion of the air inlet side of the electronics rack, thereby enhancing cooling of the electronics rack.
