Heating device for use as e.g. auxiliary heating system, in vehicle, has heat transmission ribs, where radial distance between ribs and outer side of wall area is larger in axial end area and than distance in front and/or after front wall

摘要

The device (10) has an exhaust gas collecting chamber (48) axially provided between an axial end area (52) of heat transmission ribs (46) and a front wall (56) provided at a combustion chamber component (11). The exhaust gas collecting chamber is radially placed between an inner side (40) of a circumference wall area (22) and an outer side (42) of another circumference wall area (44). A radial distance between the heat transmission ribs and outer side of the latter circumference wall area is larger in the axial end area and than distance in front and/or after the front wall.
