Definitions

  • the present invention relates to an evaporator assembly, such as may be used in a vehicle heater.
  • an evaporator assembly generally comprises a housing arrangement having a bottom area and a peripheral wall, wherein the bottom area is at least partially covered by a porous evaporator medium.
  • liquid fuel is fed via a fuel feed line into the volume region of the porous evaporator medium.
  • the fuel is distributed by Kapillarn Quapfungsober Structure of the porous evaporator medium in the direction of the combustion chamber. It has hitherto been known to cover the bottom area of such a housing arrangement with a substantially disk-like, planar porous evaporator medium. It is also known to line the peripheral wall with a substantially cylindrically shaped porous evaporator medium.
  • an evaporator assembly in particular for a vehicle heater, comprising a housing assembly having a bottom portion and a peripheral wall, wherein the bottom portion is at least partially covered by a porous evaporator medium and wherein the evaporator medium on a combustion chamber in the housing assembly side facing with a arched Brennstoffabdampfungsober Structure is formed.
  • the evaporator assembly according to the invention which is basically of the type of the so-called bottom evaporator, that the evaporator medium covering the bottom region is not designed planar or with planar Brenstoffabdampfungsober Design, but is curved here.
  • This not only affects the distribution characteristic of the fuel fed into such an evaporator medium in an advantageous manner, but at the same time also increases the available Brennstoffabdampfungsober Structure for the same covered area of the bottom area.
  • the efficiency in the fuel evaporation can be significantly improved.
  • curvature extends substantially over the entire evaporator medium, that is substantially in the region of the entire evaporator medium, this advantageous characteristic of the enlargement of the Brennstoffabdampfungsober Assembly and the better distribution is present.
  • this is formed as a curved body, for example, with a substantially constant material thickness.
  • the evaporator medium is formed on its side facing away from the combustion chamber side with a substantially planar surface. That means, that this porous evaporator medium in adaptation to the existing curvature has a varying material thickness, which leads to the advantage that the interaction with a possibly existing and the evaporation assisting bottom heating can be improved by the planar design of the rear side.
  • a curvature apex lies in a central region of the evaporator medium. In this way, a very symmetrical fuel distribution can be achieved.
  • a camber vertex is offset with respect to a central region of the evaporator medium.
  • the mounting position of the porous evaporator medium in the housing assembly and the evaporation behavior in adaptation to the desired mounting position of the evaporator assembly can be varied per se.
  • the evaporator medium may be convexly curved with respect to the combustion chamber, ie be bulged towards the combustion chamber, which is advantageous in particular when the housing arrangement is installed with the bottom area lying below.
  • the evaporator medium is concavely curved, thus providing a cavity. This is especially advantageous when the evaporator assembly is installed with overhead floor area.
  • a fuel feed line opens into the evaporator medium in the region of a curvature vertex. In this way it can be ensured that, in particular, taking advantage of gravity effects of the fuel is distributed in the desired manner on the porous evaporator medium.
  • an evaporator assembly that can be used in a vehicle heater, which could also be generally referred to as a combustion chamber assembly, is designated by 10.
  • This comprises a housing assembly 12 having a peripheral wall 14 which is generally approximately cylindrical in shape and a bottom portion 16.
  • the bottom portion 16 forms a substantially cup-like structure together with the peripheral wall 14 and may be integrally formed therewith, for example be attached as a separate assembly to the peripheral wall 14.
  • a combustion chamber 18 is provided, in which at an axial distance to the bottom portion 16 - axially relative to a longitudinal center axis A of the housing assembly 12 - air inlets 20 open.
  • the bottom region 16 is covered by a porous evaporator medium 22.
  • this porous evaporator medium 22 covers the entire bottom area 16 and rests with a peripheral edge 24 on the floor area 16 and also on the circumferential wall 14.
  • the shape of the porous evaporator medium 22 may be such that it is inserted and held under interference fit in the housing 12.
  • additional securing elements can ensure a stable mounting of the porous evaporator medium 22 in the housing assembly 12.
  • the porous evaporator medium 22 is of braided, spun, web or other porous material, such as e.g. Foam ceramic or sintered material, constructed and ensures that this fed-in liquid fuel is distributed by Kapillarrion Quassober medium 22.
  • the porous evaporator medium 22 On a side facing the combustion chamber 18, the porous evaporator medium 22 has a Brennstoffabdampfungsober Design 26 on.
  • Fuel generally hydrocarbon, can evaporate into the combustion chamber 18 via this fuel evaporation surface 26 and form an ignitable or combustible mixture with the atmospheric oxygen present there.
  • the Brennstoffabdampfungsober Type 26 of the evaporator medium 22 is designed curved, and that is configured convexly curved with respect to the combustion chamber 18
  • the evaporator medium 22 with over its the bottom portion 16 covering the extension area substantially constant material thickness or Wall thickness is designed so that not only the Brennstoffabdampfungsober
  • the entire evaporator medium 22 forms a curved body.
  • a curvature vertex 28 that is to say in the orientation in FIG. 1, the highest region of the curvature with respect to the bottom region 16, a fuel feed line 30 opens into the porous evaporator medium 22.
  • this curvature vertex 28 continues to be located centrally in the porous evaporator medium 22, wherein central reference here also refers to the central area or central area of the housing arrangement 12 or the floor area 16, essentially defined by the longitudinal center axis A.
  • the liquid fuel introduced into the porous evaporator medium 22 in the area of the centrally located crown vault 28 will not only be affected by capillary action distribute in the volume range of the porous evaporator medium 22, but also under the action of gravity. This means that the generally poorly fueled edge regions are better fed, and thus the entire fuel vapor deposition surface 26 can be more evenly utilized for fuel vapor deposition.
  • This improved Brennstoffabdampfungs characterizing also contributes that by the curved configuration of the evaporator medium 22 and the Brennstoffabdampfungsober Structure 26 thereof with the same covered surface of the bottom portion 16 in comparison to a planar evaporator medium, a larger Abdampfungsober Structure 26 is available.
  • the curvature vertex 28 of the evaporator medium 22 is offset laterally with respect to the center thereof or also the longitudinal center axis A of the housing arrangement 12.
  • existing convex curvature of the Brennstoffabdampfungsober Structure 26 and the evaporator medium 22 is thus clearly visible in Fig. 2 eccentric position and eccentric Fuel supply via the fuel supply 30 attained.
  • FIG. 4 A further variant of an evaporator assembly or combustion chamber assembly 10 according to the invention is shown in FIG. 4.
  • the evaporator medium 22 is designed with respect to the combustion chamber 18 concavely curved Brennstoffabdampfungsober Structure 26 or is formed overall as a concave curved body.
  • the curvature vertex 28 is arranged here again in the central region and forms the region of the evaporator medium 22 closest to the bottom region 16.
  • the fuel feed line 30 also opens into the evaporator medium 22 here with respect to the longitudinal center axis A in the central region.
  • This embodiment is particularly advantageous when the evaporator assembly 10 is installed as shown in FIG. 4, i. with downwardly open housing arrangement 12.
  • the liquid fuel introduced into the porous evaporator medium 22 will also be distributed very evenly into the outer edge regions of the evaporator medium 22 by the capillary action and assisted by the action of gravity.
  • the evaporator medium 22 is again formed with respect to the longitudinal center axis A offset vaulting apex 28, resulting in a correspondingly asymmetrical design of the evaporator medium 22.
  • This variant is again particularly suitable for inclined or horizontal installation, since it is then ensured that a very uniform distribution of the fuel in the porous evaporator medium 22 and a correspondingly uniform Brennstoffabdampfung in the direction of the combustion chamber 18 can be obtained by the fuel distribution unevenly influencing gravity.
  • the evaporator assembly 10 described above may be embodied differently and that it may be used for other purposes without deviating from the principles of the invention.
  • the entire bottom region 16 does not necessarily have to be covered by the porous evaporator medium 22.
