Abstract
An airflow assembly, includes a plenum, a barrel, a fan support, a fan assembly, and a plurality of ribs. The plenum includes an opening structure defining a plenum opening. The barrel extends in a downstream direction from the opening structure, and defines a barrel space and a downstream edge. The fan support is at least partially positioned within the barrel space. The fan assembly is supported by the fan support and includes (i) a motor and (ii) a blade assembly configured to rotate about an axis. Each of the ribs extends between (i) the opening structure or the barrel and (ii) the fan support. The downstream direction is parallel to the axis. An upstream direction is opposite of the downstream direction and parallel to the axis. A plane intersects the axis and is perpendicular to the axis.
