  • Apparatus and method for facilitating cooling of an electronics rack by mixing cooler air flow with re-circulating air flow in a re-circulation region
    Patent number: 7283358
    Abstract: Apparatus and method are provided for facilitating cooling of an electronics rack employing an air delivery structure coupled to the electronics rack. The air delivery structure delivers air flow at a location external to the electronics rack and in a direction to facilitate mixing thereof with re-circulating exhausted inlet-to-outlet air flow from the air outlet side of the electronics rack to the air inlet side thereof. The delivered air flow is cooler than the re-circulating exhausted inlet-to-outlet air flow and when mixed with 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.
