Abstract
A vehicle airflow system includes a centrifugal fan and an air diffuser. The centrifugal fan is configured to direct air radially outward from a rotational axis of the fan. The air diffuser has a plurality of air deflectors that are disposed radially about the fan. The air deflectors have curved surfaces. Each curved surface defines an airflow channel that has an inlet extending radially outward from a periphery of the centrifugal fan and an outlet extending axially away from the diffuser relative to the rotational axis of the fan.
