| 摘要 |
<p>The invention relates to a heating device for a motor vehicle interior compartment, particularly for an electrically powered vehicle. The device comprises an air intake (14) fitted with an air pulsing device (20), an air outlet (32) supplying at least one outlet duct (34, 36, 38) opening out into the interior compartment, an air-transmission branch (22) interposed between the air intake and the air outlet, an air heating branch (24) interposed between the air intake and the air outlet and a mixing flap (28) capable of distributing a flow of air between the two aforementioned branches. The heating branch (24) contains a resistive heating radiator (40) with a positive temperature coefficient (PTC) capable of being powered by a voltage source on board the vehicle and a preheat radiator (42) capable of being powered by a stationary external voltage source when the vehicle is parked. Application exclusively to electrically powered motor vehicles. <IMAGE></p> |
