Definitions

  • the invention relates to a heater, in particular a vehicle auxiliary heater, which has a burner component which projects into a combustion chamber delimited by a combustion tube, and which is accommodated in a burner head housing of the heater surrounding the latter.
  • the combustion air which is supplied by a combustion air fan of the heater, enters the space around the burner component.
  • a heater in particular a vehicle heater of the type mentioned above is described.
  • a burner component is provided, which can be pressed in the axial direction in the direction of the combustion tube by means of a pressing device for fixing the position.
  • the pressing device presses the burner component against correspondingly defined conditions of the burner head housing part, the burner head housing part on the one hand and the outer surface of the burner part on the other hand delimiting the space into which combustion air coming from a combustion air blower enters and which then enters the burner component.
  • the invention therefore aims at overcoming the difficulties described above to provide a heater, in particular a vehicle heater, in which the combustion air supply to the burner is cheaper, in particular with regard to optimizing the burner performance and the low pollutant content.
  • a heater in particular a vehicle heater, with a burner component projecting into a combustion chamber bounded by a combustion tube and accommodated in a burner head housing of the heater surrounding it, combustion air entering the space around the burner component, characterized in that a Jacket part surrounds the burner component in such a way that a combustion air space of a predetermined volume is limited between the inner surface of the jacket part and the outer surface of the burner component.
  • a combustion air space surrounding the burner component is thus formed largely independently of the size and design of the burner head housing part, the volume of which can be determined in advance in such a way that it is matched to the design of the burner and the desired output of the heater.
  • a defined combustion air flow to the burner component is achieved in the heater according to the invention, which is essentially independent of the design and layout of the burner head housing.
  • the burner in the heater according to the invention is designed such that the jacket part with the burner component forms a completely functional structural unit, which is independent gig of the heater housing can be checked for functionality before installing the heater.
  • the outer part of the jacket part rests on the inner surface of the burner head housing part, whereby thermal decoupling is achieved by means of the air gap between the burner part and the jacket part, through which combustion air flows, so that the burner head housing part is not in direct heat-conducting connection with the burner component .
  • the burner can thus be operated largely free of temperature influences through the burner head housing part.
  • the jacket part is divided or subdivided in the radial direction. This simplifies the assembly of the jacket part and in particular the jacket part can also be designed in such a way that further burner devices, such as flame monitors, ignition devices and the like. are carried by the burner jacket part.
  • the parting plane is preferably inclined to the outer surface of the outer part and the parts of the outer part thus formed are braced against one another in order to achieve a tight seal in the region of the parting plane.
  • the combustion air space is preferably delimited on the end face by a cover which cooperates with the burner component and which seals the combustion air space on the end face from the surroundings.
  • an inlet opening for the combustion air coming from the combustion air fan can be provided, via which the combustion air is introduced into the combustion air space.
  • This opening is preferably also sealed off from the environment, preferably by means of a sealing ring.
  • the combustion air is introduced into the combustion air space in a predetermined flow direction, so that the combustion air supply is as low-loss as possible. This will make the Ener the need of the combustion air fan is favorably influenced in the sense of a reduction.
  • the combustion air is preferably introduced into the combustion air space via the inlet opening in such a way that the combustion air is directed onto the outer surface of the burner part.
  • a section of a total of 1 heater is shown.
  • a burner tube 3 is arranged coaxially to the longitudinal center axis 4 of the heater 1.
  • the combustion tube 3 delimits a combustion chamber 5.
  • the combustion tube 3 is surrounded by a heat exchanger 6, which in turn is enclosed by the housing part 2.
  • a so-called "water heater” is illustrated which works with a liquid heat transfer medium which flows through the space between the heat exchanger 6 and the housing part 2.
  • the hot combustion gases generated in the combustion chamber 5 give off their heat to the liquid heat transfer medium, which is thereby heated and is used in the intended use for vehicle heating.
  • the hot combustion gases leave the heater 1 through an exhaust gas outlet 7.
  • the inlet area with the inlet and the outlet area with the outlet for the heat transfer medium are not shown in the drawing, since they are not in the plane of the drawing.
  • a burner component which represents the actual flame producing burner, and into which an ignition device 11, for example a glow plug, and a Flame detector 12 protrudes.
  • a so-called evaporation burner is selected as the combustion design, which comprises an absorbent body 13 which is arranged upstream of the ignition device 11 in the burner component 10 and which serves to evaporate the preferably liquid fuel supplied.
  • a jacket part generally designated 14 surrounds the burner component 10 and is arranged concentrically to it in such a way that a combustion air space 15 is formed between the burner component 10 and the jacket part 14, which is designed in the form of an annular gap.
  • this combustion air space 15 is delimited by a cover 16, which is tightly connected to the burner head housing part 2a.
  • this cover 16 there is an inlet opening 17 which is connected to an outlet (not shown) of a combustion air blower (also not shown).
  • a seal 18, which is designed in the form of a sealing ring 19, is inserted into the inlet opening 17 for sealing against the environment.
  • combustion air is introduced into the combustion air space 15 with low losses by the combustion air fan in such a way that the combustion air flow is directed onto the outer surface of the burner component 10.
  • Openings 20 are provided in a distributed arrangement over the circumference of the burner component 10, through which openings the combustion air is introduced into the interior of the burner component 10.
  • a further opening 21 is provided on the burner component 10 in the vicinity of the ignition device 11 in order to introduce combustion air into the space 22 around the ignition device, which is further delimited by a carrier 23 for the absorbent body 13.
  • the jacket part designated overall by 14, is divided in the radial direction, so that matching parts 14a, 14b are obtained.
  • the parting plane 24 is inclined to the outer surface 25 of the outer part 14 and a device 26 is provided see, by means of which the parts 14a, 14b of the jacket part 14 can be braced against one another in order to achieve a tight seal in the region of the parting plane 24.
  • the part 14a of the jacket part 14 also serves as a support for the flame detector 12, while the other part 14b thereof, which faces the cover 16, receives the ignition device 11.
  • the casing part 14 is a whole or at least a part 14a, 14b of the casing part 14 is made of a light metal or a light metal alloy, such as made of aluminum or an aluminum alloy. As a result, the weight for the additionally provided jacket part 14 can be reduced.
  • the jacket part 14 expediently lies at least partially on the inner surface of the burner head housing part 2a and is supported by the latter.
  • an annular space serving as the combustion air space is formed around the burner component 10, the volume of which, in order to optimize the combustion properties of the burner, to the desired design of the heater and the like. can be coordinated. Furthermore, can be chosen by the predetermined air volume, which is largely independent of the size and shape of the burner head housing part 2a, so that vibrating air volumes are avoided. This results in a low-noise operation of the burner and the heater 1 as a whole. Furthermore, the jacket part 14 enables a thermal decoupling of the housing part 2 and the burner head housing part 2a, so that the burner is largely free of temperature influences of the housing part 2.
  • the present invention is not limited to the details of the above-described embodiment, but the casing part 14 can also be configured differently, provided that the aim of the predetermined volume of the combustion air space around the burner component 10, which is the aim of the invention, is achieved.
