Patent ID: 8656985

Claim:
A rackmount rear door heat exchange apparatus, comprising: an external structure, supportive of a computing device, through which an airflow for cooling the computing device is generated; first and second doors sequentially coupled to the external structure downstream from the computing device such that the that first door is disposed in an intervening position between the computing device and the second door and fluidly interposed between the computing device and the second door such that the airflow flows over the computing device, the first door and, subsequently, the second door; a water supply system fluidly coupled to a water supply and to the first and second doors to thereby supply water to the first and second doors by which the airflow is cooled; first and second valves coupled to the water supply system for association with the first and second doors, respectively, each valve being configured to close and to thereby block a supply of water to the associated door during service of the associated door; and an exhaust system, disposed proximate to the external structure, configured to recycle the cooled airflow downstream from the second door and to transfer the cooled airflow upstream from the computing device for repeated cooling of the computing device the exhaust system being configured to transfer recycled airflow upstream from the computing device and comprising: an airflow receiving unit disposed downstream from the second door; and an airflow generating unit disposed upstream from the computing device such that: the second door is disposed in an intervening position between the first door and the airflow receiving unit, the computing device is disposed in an intervening position between the airflow generating unit and the first door, and Where the airflow flows in a linear direction from the airflow generating unit, over the first door, over the second door, and then to the airflow receiving unit.
