An air conditioning device for a motor vehicle integrating a double flow heat spreader

The invention relates to a device (1) dual air conditioner flux motor vehicle, comprising an enclosure (2) containing an evaporator (3) and a radiator (4). A lower air flow admitted through lower inlet (6) successively through a lower portion of the evaporator (3) and radiator (4) before being discharged from a bottom outlet (7). An upper air flow admitted through an upper air inlet (9) successively passes through an upper portion of the evaporator (3) and radiator (4) before being discharged from an upper outlet (12, 13, 14 ). The device of the invention comprises a first distribution flap (17) located between the evaporator (3) and radiator (4) and a second distribution flap (18) located between the radiator (4) and the outputs of air (12, 13, 14). Each flap separates the underflow from the upper stream having an edge along one side of the radiator (4) while being movable between an upper position and a lower position.
