Claim 7:
8. A heat exchange section of a heating, ventilation, and/or air conditioning (HVAC) unit, comprising:
a plurality of panels defining an air flow path through the heat exchange section;
an upstream portion of the air flow path defined by the plurality of panels, wherein the upstream portion comprises an inlet of the heat exchange section and a first cross-sectional area;
a downstream portion of the air flow path defined by the plurality of panels, wherein the downstream portion comprises an outlet of the heat exchange section and a second cross-sectional area greater than the first cross-sectional area of the upstream portion, wherein the plurality of panels defines an interface between the upstream portion and the downstream portion, the upstream portion defines an upstream volume extending from the inlet to the interface, the first-cross-sectional area of the upstream portion is substantially constant from the inlet to the interface, and the downstream portion defines a downstream volume extending from the interface to the outlet; and
a heat exchanger disposed within the air flow path, wherein the heat exchanger comprises an upstream edge disposed within the upstream volume and a downstream edge disposed within the downstream volume.
