A furnace has a cabinet having at least one wall at least partially defining an interior space of the cabinet, a heat exchanger disposed in the interior space, and a protrusion formed integrally with the at least one wall, the protrusion extending generally inward into the furnace to at least partially obstruct a circulation airflow through the cabinet.

Furnace cabinet with integral protrusion

Systems and methods are disclosed which may include (1) providing a preselected and/or non-uniform airflow distribution output from a heat exchanger, (2) selectively directing air through a relatively lower resistance flowpath to manage an airflow characteristic and/or distribution downstream of the heat exchanger, (3) providing an HVAC system comprising a heat exchanger comprising a fin arrangement configured to cause relatively more air to contact a selected component that lies either upstream or downstream relative to the heat exchanger, and (4) receiving a relatively uniform airflow into a heat exchanger and outputting an airflow comprising a localized increased airflow rate. A heat exchanger comprising differentiated resistance flowpaths may selectively affect a direction and/or localized flow rate or distribution of an airflow exiting the heat exchanger.
