Definitions

  • the present invention relates to an evaporator assembly for a vehicle heater or reformer, comprising a metal support, an evaporator medium carried on the support, and a heating element.
  • Such evaporator arrangements are used, for example, in so-called evaporator burners, in order to be able to distribute this liquid fuel by introducing the initially liquid fuel into the usually porous evaporator medium due to the capillary action in the volume range of the porous evaporator medium and to be able to evaporate over a comparatively large surface area.
  • the shell-like support is generally constructed of metal material, so for example made of sheet metal.
  • an electrical heating element, the carrier and the evaporator medium are sandwiched on one another.
  • the support is usually designed to be relatively thin, so that it thermally deforms during temperature changes. This can lead to voids between the carrier and the heating element, resulting in poorer contact between the heating element and the carrier result.
  • the strength of the carrier could be improved, but at the same time the thermal mass would thereby also increased, whereby the carrier would heat up slower and thus the evaporation of the fuel would take place more slowly after a start of the evaporator assembly.
  • the US 2004/0173692 A1 discloses an evaporator arrangement in which a porous evaporator medium is provided on a cup-shaped carrier on a side facing a combustion chamber to be positioned. At the rear side, that is, the side facing away from the combustion chamber side of the carrier, a evaporation heating element designed as a heating conductor is arranged in a recess provided for this purpose.
  • the US 4,611,985 A discloses an evaporator which, on the side of a carrier facing a combustion chamber, on which side also a porous evaporator medium is arranged, has a pin-like projection which absorbs heat during combustion operation and conducts it to the carrier which applies the porous evaporator medium.
  • the EP 1 484 552 A1 discloses an evaporator assembly in a vehicle heater wherein a plate member disposed opposite to a porous evaporator medium and heatable by an electrically energizable heater comprises a pin-like projection passing through the porous evaporator medium which serves locally in the region of the combustion chamber in a starting phase high temperatures produce that ignition occurs.
  • a vehicle heater with an evaporator assembly in which a porous evaporator element is provided on the side facing a combustion chamber side of a carrier constructed of ceramic material.
  • an electrically energizable heating element is arranged, which is covered on its side facing away from the carrier by a potting compound.
  • an evaporator assembly for a vehicle heater or a reformer is provided, as defined in claim 1.
  • the inventive material-locking connection of the heating element with the metal carrier ensures good heat transfer from the heating element to the carrier even when the carrier is thermally deformed. That is, in the evaporator arrangement according to the invention, a consistently good evaporation performance can be ensured and the energy introduced can be reduced by the good heat transfer with the same effect, since less losses occur.
  • heating element it is conceivable to connect the heating element to the carrier by means of a temperature-resistant adhesive or by welding, but it is particularly preferred that the heating element is materially connected to the carrier by soldering or Ansintern.
  • the heating element comprises an electrically operated wound heating conductor.
  • the heating element designed as a heating element is arranged on the side facing away from the evaporator medium side of the carrier, whereby the heating element does not come directly into contact with the fuel in the evaporator medium in contact and a more uniform heat distribution in the evaporator medium is achieved.
  • the present invention provides a method for producing an evaporator arrangement according to claim 4
  • the material-locking connection of the heating element with the carrier can be carried out simultaneously with a soldering process for connecting a fuel inlet pipe to the evaporator arrangement, so that no additional operation for the installation of the heating element is required.
  • Fig. 1 is an evaporator assembly for an evaporator burner of a vehicle heater or for a reformer generally designated 10.
  • This evaporator assembly 10 comprises a flame tube 12, in which a combustion chamber housing 14 is arranged, into which, for example, via the openings 16 combustion air is introduced.
  • liquid fuel is introduced into an evaporator arrangement 20 arranged in the combustion chamber housing 14.
  • the evaporator arrangement 20 is fastened, for example by means of a securing ring 28 to the combustion chamber housing 14 and comprises a cup-shaped carrier 22, in which a porous evaporator medium 24 is arranged.
  • the carrier 22 is made of metal, for example, from sheet metal.
  • the evaporator medium 24 may comprise interconnected regions 24a, 24b, which may, for example, due to different pore size for a uniform distribution of the fuel as possible.
  • At the side remote from the evaporator medium 24 side of the carrier 22 designed as a wound heating conductor heating element 26 is arranged.
  • the liquid fuel introduced into the evaporator arrangement 20 through the fuel inlet pipe 18 is distributed in the porous evaporator medium 24, which in turn is heated by the heating element 26, so that the liquid fuel in the evaporator medium 24 is evaporated.
  • the heating element 26 is connected by solder joints 30 materially connected to the carrier 22. These solder joints 30 are preferably mounted substantially along the entire length of the heating element 26. In the manufacture of the evaporator assembly 10, these solder joints 30 can be made in the same operation as connecting the carrier 22 to the fuel inlet pipe 18.
  • the heat-conducting cross section between the heating element 26 and the carrier 22 is significantly improved by the solder joints 30, since the original line contact between these two components is replaced by a flat contact.
  • the two components are so firmly connected to each other by the solder joints 30 that thermal or mechanical deformation of the carrier 22, the heat-conducting connection between the heating element 26 and the carrier 22 can not deteriorate. Since no soiling and deposits can form between the heating element 26 and support 22 in the evaporator arrangement 20 according to the invention, the heat-conducting connection is ensured over the entire service life of the evaporator arrangement 20.
  • the introduced electrical energy can be reduced for a constant evaporation performance, since less heat transfer losses and heat flow occur clearer direction is given.
  • connection of the heating element 26 to the support 22 could be made by a heat-resistant and thermally conductive adhesive, by welding or by sintering.
