HVAC HVAC Air mixing device of HVAC module for vehicles and HVAC module including same

摘要

An air mixing device, which is arranged in a space where hot air passing through a heater core of a heating, ventilating, and air conditioning (HVAC) module meets cold air passing through an evaporator core to mix the hot air with the cold air, comprises: a plurality of hot air guide pipes forming each hot air guide passage guiding the hot air to a de-frost discharge opening; a first cold air guide positioned on a downstream side of the hot air guide pipe to allow a cold air guide passage, which guides the cold air to a vent discharge opening and a foot discharge opening, to be formed between the hot air guide pipes; and a second cold air guide installed to divide an air flow through the cold guide passage. The hot air guide pipe has a hot air branching window formed to allow a part of the hot air flowing through the hot air guide passage to be branched to be mixed with the cold air passing through the cold air guide passage. The air mixing device is able to elaborately adjust the temperature in each mode.
