Heat exchanger door for an electronics rack

An assembly comprising:

• an electronics rack, the electronics rack comprising an air inlet side and an air outlet side, wherein air moves through the electronics rack from the air inlet side to the air outlet side thereof;
• a heat exchanger door hingedly mounted to the electronics rack at one of the air inlet side or the air outlet side thereof, the heat exchanger door comprising:
• a door frame sized and configured to span at least a portion of the air inlet side or the air outlet side of the electronics rack, the door frame comprising an airflow opening, the airflow opening facilitating the ingress or egress of airflow through the electronics rack with the heat exchanger door latched to the electronics rack at the air inlet side or the air outlet side thereof;
• an air-to-coolant heat exchanger supported by the door frame and disposed so that the airflow through the airflow opening passes across the air-to-coolant heat exchanger, the air-to-coolant heat exchanger configured to extract heat from the airflow passing thereacross;
• a door latch mechanism to selectively latch the heat exchanger door to the electronics rack;
• and
• a catch bracket attached to the electronics rack and extending from the electronics rack into the heat exchanger door through a catch opening in the heat exchanger door to facilitate latching of the heat exchanger door to the electronics rack, wherein the door latch mechanism is configured to, and mounted within the heat exchanger door to, physically engage the catch bracket within the heat exchanger door, and thereby latch the heat exchanger door to the electronics rack.
