Abstract
An air flow mixing system for a vehicle air conditioning system having a distribution door to force air from a first air flow to mix with a second air flow of different temperature proximate a merging region in the air conditioning system. In one embodiment, the distribution door has an arcuate passageway or scoop to forcibly route air from the first airflow to the second airflow. In a second embodiment, the distribution door has at least one projecting channel to divide each of the first and second air flows into a plurality of alternating flow paths to promote heat transfer and mixing of the two airflows. In each embodiment, the pivoting distribution door facilitates heat transfer between the airflows resulting in a more even temperate airflow emerging from the merging region.
