ABSTRACT:
A heater core is placed within a casing at a location substantially remote from an air inlet formed in a side wall of the casing. The heater core is arranged such that air introduced into the heater unit is guided to the underside of the heater core and then upwardly flows through it. An air-mix damper is supported on the heater core at a side facing the air inlet, with its free end arranged to be seated on the upper and lower edge surfaces of the air inlet so that it can be pivoted through a sufficiently large angle. The heater core and the air-mix damper have their walls cooperating with associated inner walls of the casing to define upper and lower air passages. Further defined in a zone immediately above the heater core is an air mixing chamber wherein cold air delivered through the upper air passage and warm air delivered through the lower air passage and the heater core are collided with each other at substantially right angles. An upper or face air outlet and a defroster air outlet which are connected to their respective air grilles provided in the instrument panel of an automotive vehicle associated with the air conditioning system.
