Claim 0:
1. A heating, ventilation, and/or air conditioning (HVAC) unit, comprising:
a heat exchange section comprising a plurality of panels defining an air flow path through the heat exchange section, wherein the air flow path comprises an upstream portion and a downstream portion separated by an interface, the upstream portion comprises an upstream volume extending from an inlet of the air flow path to the interface, the upstream volume comprises a first cross-sectional area, the downstream portion comprises a downstream volume extending from the interface to an outlet of the air flow path, the downstream volume comprises a second cross-sectional area greater than the first cross-sectional area, and the second cross-sectional area increases from the interface to the outlet; and
a heat exchanger comprising an upstream edge disposed within the upstream volume and a downstream edge disposed within the downstream volume, wherein the heat exchanger overlaps with the interface such that a first portion of the heat exchanger is disposed within the first cross-sectional area of the upstream volume and a second portion of the heat exchanger is disposed within the second cross-sectional area of the downstream volume.
