INTAKE HEATER FOR HVAC FRESH AIR INTAKE

摘要

A vehicle having a cowl tray and a Heating, Ventilation, and Air Conditionin g (HVAC) system is provided with one or more coolant-to-air heat exchangers near the intake opening of the HVAC system or attached to the cowl tray, in order to prevent an accumulation of snow and ice from blocking the flow of intake air into the HVAC system and interferin g 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 bas e of the vehicle windshield, due to turbulent precipitation.
