Definitions
- the present invention relates to a combustion chamber arrangement, in particular for a vehicle heater, comprising a combustion chamber housing an outer wall and a bottom wall, being in the bottom wall a combustion air supply area for supplying combustion air provided in a combustion chamber formed in the combustion chamber housing is.
- combustion air For heaters, especially vehicle heaters, that is in one Combustion air fed combustion air generally the ambient air, so that this combustion air when feeding into the combustion chamber generally also has ambient temperature.
- the combustion air is axial, i.e. in the Direction of the longitudinal center axis of a combustion chamber or a flame tube is promoted to the combustion chamber housing, this occurs first in Contact with the bottom wall of the combustion chamber housing or one Area of this bottom wall. This causes this bottom wall is cooled comparatively strongly.
- a combustion chamber arrangement in particular for a vehicle heater, comprising a combustion chamber housing with an outer wall and a bottom wall, wherein In the bottom wall a combustion air supply area for supplying Combustion air into a combustion chamber formed in the combustion chamber housing is provided, with a limiting element in the combustion chamber housing is provided which is an effective area for combustion the combustion chamber limited to the bottom wall.
- combustion chamber arrangement thus ends by Providing the limiting element that area in the combustion chamber housing formed combustion chamber in which combustion can take place and which is therefore used effectively for combustion, already at a distance to the bottom wall.
- the consequence of this is that between that area, in which combustion takes place, and comparatively from the outside strongly cooled bottom wall a reduced heat transfer contact is provided and thus the temperature level in the combustion chamber or the area in which combustion takes place is essential is more uniform.
- the limiting element to be provided according to the invention to be able to further improve the insulation effect introduced suggested that between the limiting element and the bottom wall a space is provided.
- the one between the delimiter and the space formed by the bottom wall thus forms an insulation layer that further reduces heat transfer from the combustion chamber or the combustion taking place in it Combustion chamber housing causes in this area.
- Combustion chamber arrangement can be provided that from the bottom wall a combustion air inlet section runs out and that the Bounding element worn on the combustion air inlet section is.
- the present invention further relates to a heater, in particular for Vehicles comprising a combustion chamber arrangement according to the invention and a combustion air blower, which combustion air in the direction of the Bottom wall of the combustion chamber housing to and through the combustion air inlet area promotes it into the combustion chamber.
- the combustion chamber arrangement 10 comprises an essentially pot-like designed combustion chamber housing 12 with a substantially cylindrical or annular outer wall 14 and one, for example integrally designed and a combustion chamber 16 on one side axially - 12-delimiting with respect to a longitudinal center axis L of the combustion chamber housing Bottom wall 18.
- Integrally formed with the bottom wall can also have a combustion air inlet connection, which is likewise provided essentially in a ring Be 20, so in the then essentially annular bottom wall 18, a combustion air supply area 22 is formed, in which those only indicated schematically Combustion air blower 24 brought up and indicated by an arrow B. Combustion air can flow.
- combustion air inlet connection 20 which essentially also has an inner wall of the combustion chamber housing 12 so that a substantially annular Combustion chamber 16 is formed, several are distributed in the circumferential direction Combustion air inlet openings 26 are formed so that the through the Combustion air blower 24 initially supplied combustion air P flows towards the bottom wall 18 in the direction of the longitudinal axis L.
- the combustion air supply area 22 into the combustion air inlet connection 20 arrives and through the combustion air inlet openings 26 then flows essentially radially outwards and thus into the Combustion chamber 16 arrives.
- a porous evaporator medium 30 is provided on an inside 28 of the outer wall 14 of the combustion chamber housing 12.
- This porous Evaporator medium 30 is preferably designed to cover the entire Covering inside 28.
- Via a fuel line, not shown becomes liquid fuel from the outside through the outer wall 14 sprayed into the porous evaporator medium 30 so that it is below Capillary delivery effect distributed therein and towards the combustion chamber 16 lying surface of the porous evaporator medium 16 then evaporates.
- Combustion air P also introduced is a combustible or ignitable air / fuel mixture generated.
- glow ignition element can initiate the ignition so that when the ignition is off the combustion exhaust gases the open end region axially distant from the bottom wall 18 emerge from the combustion chamber 16 and in one in the direction of the longitudinal axis L enter the elongated flame tube 32 and there through a flame shield 35 flow through.
- limiting element 34 in the form of an annular disk is provided in the combustion chamber housing 12 . In the example shown, this is on the combustion air inlet connection 20 pushed on and rests on a shoulder 36 formed thereon. to fixed bracket, a locking ring can be provided. Is also one correspondingly tight fit between the limiting element 34 and the combustion air inlet connection possible.
- the limiting element 34 is positioned so that it is at a distance from the bottom wall 18, so that between the bottom wall 18 and this limiting element 34 a space 38 is formed. Through the limiting element 34 thus becomes the combustion chamber 16 provided in the combustion chamber housing 12 divided into two areas, namely the one already mentioned Gap and the other one on the other side of the delimitation element 34 still effective effective for combustion Area 40.
- the limiting element 34 takes over in the combustion chamber arrangement according to the invention 10 an aperture function so that through the foregoing mentioned division of the entire combustion chamber 16 in the for the combustion effective area 40 and the one not for combustion effective area or space 38 an insulation area to the bottom wall 18 is created.
- this space 38 is namely solely due to the fact that essentially no combustion air no combustion will take place in this area.
