Abstract
An airflow turning device with airflow control channels for an outlet of a heating, ventilation, and air conditioning (HVAC) case that directs airflow to a plurality of different vehicle outlets. The airflow control channels extend from an inner upstream side of the outlet to an outer downstream side of the outlet. Different ones of the plurality of channels have different lengths to generate a varied pressure drop at the outer downstream side in response to airflow blown into the plurality of channels from the inner upstream side.
