Abstract:
1. An apparatus for cooling electronic components housed in a computer rack for providing cooling during performance of maintenance operations, comprising: a heat exchange assembly comprising an air-to-liquid heat exchanger disposed within an outlet door of said computer rack, the outlet door being pivotably mounted to an air outlet side of the computer rack; the outlet door comprising a plurality of louvers which open or close with the closing or opening of the outlet door, respectively, the air-to-liquid heat exchanger being mounted in the outlet door such that when the outlet door is closed, egressing exhaust air from the air outlet side of the computer rack passes across the air-to-liquid heat exchanger before passing through the plurality of louvers; at least one air moving device(s) disposed on said outlet door; an activator for activating the at least one air moving device(s) with the opening of the outlet door and deactivating the at least one air moving device(s) with the closing of the outlet door; the at least one air moving device(s) being disposed such that when activated, exhaust air egressing from the air outlet side of the computer rack is drawn across the air-to-liquid heat exchanger; and a containment plate secured to a top of said the outlet door and disposed to facilitate exhaust air egressing from the air outlet side of the computer rack being drawn through the air-to-liquid heat exchanger when the outlet door is opened and the at least one air moving device(s) is activated, and to inhibit the exhaust air from returning directly to an air inlet side of the computer rack without passing through the at least one air moving device(s).
