Claim 12:
13. A heating, ventilation, and/or air conditioning (HVAC) unit, comprising:
a first panel defining an upstream portion of an air flow path through a heat exchange section of the HVAC unit, wherein the upstream portion comprises an inlet of the heat exchange section and an upstream volume comprising a first cross-sectional area, wherein the first panel and the upstream volume each extends in a downstream direction from a first end of the first panel to an interface, and wherein the first cross-sectional area is substantially constant from the inlet to the interface;
a second panel defining a downstream portion of the air flow path, wherein the downstream portion comprises an outlet of the heat exchange section and a downstream volume comprising a second cross-sectional area greater than the first cross-sectional area, the second panel extends from the interface at an oblique angle, relative to the first panel, along the downstream direction to a second end of the second panel, the downstream volume extends from the interface to the second end of the second panel, and the second cross-sectional area of the downstream volume increases 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.
