More Information
Summary:A vehicle having a cowl tray and a Heating, Ventilation, and Air Conditioning (HVAC) system is provided with one or more coolant-to-air heat exchangers (119) near the intake opening (114) of the HVAC system or attached to the cowl tray (109), in order to prevent an accumulation of snow and ice from blocking the flow of intake air into the HVAC system and interfering with the windshield wiper system. The accumulation of snow and ice in the HVAC intake is a problem commonly experienced by vehicles having the HVAC intake located near the base of the vehicle windshield, due to turbulent precipitation.
