1. A rack assembly for cooling a computer system, comprising:

  • a rack providing support for one or more columns of heat-generating electronic devices and device fans for moving air from an air inlet side of the rack through the devices and through an air outlet side of the rack;

    a unitary door having a support frame spanning the air outlet side of the rack and a hinge pivotally coupling the door to a rear vertical edge of the rack, wherein the unitary door includes an air-to-liquid heat exchanger panel spanning an air outlet passage inside the support frame so that substantially all of the air passing through the air outlet side of the rack must pass through the heat exchanger panel; and

    a coolant circulation system including a coolant distribution unit for chilling liquid coolant, a supply hose placing the coolant distribution unit in fluid communication with an inlet manifold of the air-to-liquid heat exchanger, and a return hose placing an outlet manifold of the air-to-liquid heat exchanger in fluid communication with the coolant distribution unit, wherein the supply hose and return hose are routed outside the cross-sectional area of the air outlet passage.
