摘要

The engineering part has a heating device for supplying air to heat a passenger compartment. An air nozzle (1) comprises air guiding element (9), and discharges air in an interior of a motor vehicle, and an air duct (2) with a channel wall (3) arranged at outside of a housing. The channel wall passes the air from an air outlet opening to an air nozzle, where density of the channel wall is less than 0.5 kg/dm power cube (dm3), 0.3 kg/dm3 or 0.2 kg/dm3 or 0.1 kg/dm3. The channel wall is partially or completely made of froth material.
