The utility model relates to transport engineering, advantageously to systems for heating and ventilating vehicle passenger compartments. The technical result of using the utility model consists in expanding the functional possibilities by arranging elements of the thermal curtain in the space above the door in the vehicle without restricting the space for arrangement of a door drive mechanism and place for the operation thereof. The device has smaller overall dimensions on account of a reduction in the dimensions of the heating unit. The device has a casing fixed in the upper part of a door opening in a vehicle body, a ventilation unit arranged in said casing and having an air-distributing diffuser box, a unit for controlling the fans, and a protective filter. The heater is a thermal unit consisting of heating rod elements which, for electric vehicles, are in the form of electric heaters - a unit of thermoelectric heaters in the form of ribbed insulated electric resistances, and, for motor vehicles, are in the form of ribbed tubular heat exchangers in a housing made of electrothermally stable plastic. |
