  • Automotive heating, ventilating and air conditioning module with improved air mixing
    Patent number: 6368207
    Abstract: An HVAC housing includes a novel structure to aid the mixing of hot and cold air downstream of the evaporator and heater core. A series of space, parallel, C shaped channels running transverse to the cold air stream and generally in line with the hot air stream act to smoothly constrict the cold air stream in the gaps between the outer surfaces of the channels, while hot air concurrently runs through the inside of the channels. As the cold air passes over the edges of the channel walls, hot air is drawn out and thoroughly mixed.
