Abstract: A combustion chamber assembly unit, especially for a vaporizing burner and particularly especially for a vehicle heater, includes at least two combustion chamber elements (12, 20, 26, 32, 50, 52, 64, 102, 126) with wall areas (12, 34, 46, 54, 64, 104, 130, 140, 142). The at least two combustion chamber elements are arranged in a radially staggered pattern in relation to a longitudinal axis (L) of the combustion chamber and are fixed to one another by laser welding.

Abstract: A vaporizing burner combustion chamber assembly unit, especially for a vehicle heater, includes a bottom part (32) with a bottom wall (34) and with a first circumferential wall (38) and a porous evaporator medium (42) at least partially covering a front side of the bottom wall, which is to face a combustion chamber (14). A ring-shaped holding part has a second circumferential wall (54) and a contact area (56) touching the porous evaporator medium. The first circumferential wall extends, from an outer edge area (36) of the bottom wall essentially in a longitudinal axis (L) direction of a bottom assembly unit (30), on a rear side of the first bottom wall facing away from a combustion chamber, in the direction away from the porous evaporator medium. The second circumferential wall extends at least partially over the first circumferential wall on its outer side and is fixed to same.
