    摘要: An airflow assembly includes a fan, a shroud, a plurality of ribs, and a fan support. The fan has a number of fan blades. The shroud includes (i) a plenum defining a plenum opening located adjacent to the number of fan blades, and (ii) a barrel extending from the plenum so as to surround the plenum opening. The plenum further defines at least one airflow opening spaced apart from the plenum opening. Each of the plurality of ribs extends inwardly from the barrel. The fan support is attached to the plurality of ribs and is configured to support the fan. The at least one airflow opening is not an attachment structure or a guiding structure, is not configured to receive a fastening member, and does not function as a water drain.
