Abstract:
1. A method comprising: providing a heat exchanger door configured to hingedly couple to an electronics rack along a hinge axis and reside at one of an air inlet side or an air outlet side of the electronics rack, and wherein the heat exchanger door comprises: a door assembly 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 assembly comprising an airflow opening, the airflow opening facilitating the ingress or egress of airflow through the electronics rack with the heat exchanger door coupled thereto, the door assembly comprising: an air-to-coolant heat exchanger disposed so that airflow through the airflow opening passes across the air-to-coolant heat exchanger, the air-to-coolant heat exchanger to extract heat from the airflow passing thereacross, and comprising: a heat exchanger core and a heat exchanger casing coupled to the heat exchanger core, the heat exchanger core comprising at least one coolant-carrying channel which loops through the heat exchanger casing; and a vertically-extending casing portion; and a structural support attached to the heat exchanger casing, the structural support comprises a vertically-extending structural support attached to the vertically-extending casing portion, the vertically-extending structural support and attached to the vertically-extending heat exchanger casing defining a tubular door support structure, wherein the at least one coolant-carrying channel loops through the heat exchanger casing within the tubular door support structure defined by the structural support and the heat exchanger casing, wherein the hinge axis passes through the tubular door support structure of the heat exchanger door.
