PURPOSE:To reduce the dispersion of the blow-out temperature by installing a guide damper so that the air stream which passes through a heat exchanger and the stream which makes a detour around the heat exchanger collide at a right angles or more and allowing the air to blow out in the direction crossing at right angles with the direction towards the heat exchanger. CONSTITUTION:A main damper 3 is positioned according to the demanded car compartment temperature, and air stream is divided into a stream C which makes a detour around a heater core 2 and a stream B which passes through the heater core 2. A guide damper 4 follows in nonlinearity according to the position of the main damper 3 so that the divided stream B' which passes through the heater core 2 always collides at an angle over 90 deg. with the divided stream C. Therefore, the divided stream B' which passes through the heater core 2 collides at right angles with the divided stream C, and a sufficiently mixed air stream D is formed. Said mixed air stream D is blown out from a blow-out port 5 directed at right angles to the heater core 2. Therefore, the blow-out temperature can be made uniform. |
