Abstract:
1. A heating, ventilating and cooling system for a vehicle comprising: a die cast housing defining an interior volume and including a first air inlet, a second air inlet, a face vent outlet and a floor vent outlet different than the face vent outlet, the interior volume defining an airflow path between the first and second air inlets and the face and floor vent outlets; an evaporator in fluid communication with the first air inlet; a heating element in fluid communication with the second air inlet; a blower in fluid communication with at least one of the evaporator and the heating element; and a stationary baffle engaging an interior wall of the housing downstream of the first and second air inlets, the baffle including a plurality of integrally formed stationary fins extending into the interior volume and simultaneously distributing a first predetermined airflow volume greater than zero to the face vent outlet and a second predetermined airflow volume greater than zero to the floor vent outlet, the plurality of stationary fins extend in a direction substantially perpendicular to a die pull direction of the housing, the plurality of fins progressively decreasing an amount of the first predetermined airflow volume to the first air outlet and progressively increasing an amount of the second predetermined airflow volume to the second air outlet between a first end of the plurality of fins and a second end of the plurality of fins opposite to the first end, wherein at least one of the plurality of stationary fins is substantially planar and at least one of the plurality of stationary fins is curved to direct air toward the floor vent outlet, wherein warm air from the first air inlet is allowed to mix with air from the second air inlet upstream of the baffle.
