Definitions

  • the present invention relates to a heat exchanger assembly for a heater, in particular vehicle heater, comprising an inner heat exchanger housing, which together with an outer heat exchanger housing, called jacket, a flow space for medium to be heated, as it is known from DE-A-10207953 is known.
  • the heat exchanger housing receives heat from the combustion exhaust gases flowing therein and transports it toward the medium to be heated, for example, a liquid medium, such as e.g. Water.
  • the heat transfer from the hot combustion exhaust gases to the medium to be heated should take place as far as possible without heat transfer losses, i. through the inner heat exchanger housing as low as possible heat transfer resistance to be provided. Since the two heat exchanger housings are generally made of the same material, there is the problem that the medium to be heated, which receives heat via the inner heat exchanger housing, then transfers this heat to the outer heat exchanger housing and from there the heat to the environment is emitted as radiant heat.
  • this object is achieved by a heat exchanger arrangement for a heater, in particular vehicle heater, according to claim 1.
  • magnesium or a magnesium-containing material such as a magnesium alloy
  • the inner heat exchanger housing made of aluminum or aluminum-containing material is for efficient heat transfer from the combustion exhaust gases to the medium to be heated.
  • a heat exchanger assembly according to the invention is generally designated 10.
  • This heat exchanger assembly 10 is shown here in combination with a heater 12, of which the essential system areas are recognizable.
  • the heater comprises a pot-like combustion chamber housing 14, which encloses a combustion chamber 16.
  • the fuel to be combusted and the combustion air required for this purpose are fed, and the combustion exhaust gases generated in the combustion chamber 16 combustion flow from the open towards the longitudinal axis L combustion chamber housing 14 through a flame cover 18 in a subsequent to the combustion chamber housing 14 Flame tube 20 a.
  • the hot combustion exhaust gases exit in the direction of the arrows, are deflected by the heat exchanger arrangement 10 and flow back on the outside of the flame tube 20. During this backflow and when impinging on the heat exchanger assembly 10, the combustion exhaust gases transfer heat to the heat exchanger assembly 10 and thus a medium to be heated flowing therein.
  • the heat exchanger assembly 10 comprises a cup-shaped inner heat exchanger housing 24 and an outer heat exchanger housing 26 surrounding it and substantially also pot-shaped. These two pot-shaped heat exchanger housings 24, 26 are fixedly connected to each other in an edge region 28 to produce a substantially tight seal, for example by gluing. In this way, a flow space 30 is formed between the two heat exchanger housings 24, 26, which can flow through the medium to be heated, that is, for example, a liquid such as water or the like. For this purpose, not shown inlet and outlet openings are present, which is a flow through the heat exchanger assembly 10 allow.
  • combustion exhaust gases impinge on a bottom portion 32 of the inner heat exchanger housing 24 and are deflected by this radially outward.
  • the combustion exhaust gases then flow back in the direction of the combustion chamber housing 14 and then leave the arrangement in the region of an outlet opening.
  • the combustion exhaust gases transfer heat to the inner heat exchanger housing 24, which in turn emits the heat to the medium flowing in the flow space 30.
  • the inner heat exchanger housing 24 may be provided on its outer side with a helical projection configuration 38 which on the one hand increases the interaction surface and on the other hand ensures that the medium flowing in the flow space 30 takes a helical path and thus a comparatively has long interaction path for heat absorption. Also in the bottom region 32, projections 40 may be formed for improved heat transfer.
  • the inner heat exchanger housing 24 should be constructed of a material which on the one hand can be exposed to the high temperatures of the combustion exhaust gases, but on the other hand has a comparatively low thermal resistance.
  • a material for constituting the same which ensures that the heat received in the medium to be heated remains substantially contained therein.
  • this outer heat exchanger housing 26 made of magnesium or a magnesium-containing material, such as. B. a Magesiumlegtechnik constructed. This material has a significantly lower coefficient of thermal conductivity compared to aluminum with approx.
  • magnesium also has a significant weight reduction compared to, for example, constructed of aluminum housings result. Also, using this material this outer heat exchanger housing can be made with thinner material thickness, which on the one hand a compact design is made possible and on the other hand, due to the lower material volume and the higher price of magnesium can be compensated compared to aluminum. Furthermore, magnesium or a magnesium alloy material is characterized by a very high corrosion resistance and a better castability compared to aluminum, which in turn results in longer tool life. In the production of such housing components made of magnesium or a magnesium alloy very low manufacturing tolerances can be achieved. In addition, this material is characterized by a good workability. Finally, magnesium can also be prepared by bonding methods, such. B. bonding, very stable with other materials, such. As aluminum, connect, so that a fluid-tight termination of the flow space 30 can be ensured.
  • the configuration of the heat exchanger assembly 10 shown in the figure with respect to the structural design of the outer heat exchanger housing 26 and the inner heat exchanger housing 24 is only exemplary.
  • other projection formations may be provided, as well as the shape of the outer heat exchanger housing may be selected differently at its outer peripheral region, for example, adapted to specific space requirements of this heat exchanger assembly receiving vehicle.
