Definitions

  • Condenser housing with at least one thin wall and this condenser housing containing condensation dryer
  • the invention relates to a capacitor housing having at least one thin wall, in particular a thin thermally conductive wall, and a condensation dryer containing this capacitor housing.
  • a closed hot air circuit in particular for drying laundry
  • an open cooling air flow generally operate.
  • the laundry to be dried is heated, which absorbs evaporating water and transported to a heat exchanger (condenser).
  • the water contained in the process air stream condenses due to the cooling with the cooling air.
  • the water is separated from the process air stream and disposed of separately.
  • the dewatered process air stream is reheated by a heating unit and then passed through the laundry to be dried again.
  • a condensation dryer with associated components is described for example in DE 102 59 343 A1 or DE 199 08 801 A1.
  • a condenser is therefore constructed so that a large area cooled by an air flow exists as a condensing surface for precipitating the water from the process air. The larger this area, the more effective the condenser works.
  • the temperature difference, by which the process air must be cooled, so that an efficient condensation is possible, can be the lower, the larger the condensation surfaces are with the same size of the condenser.
  • EP 1 050 618 B1 proposes a heat exchanger with a plurality of heat exchanger plates arranged one above the other for a household laundry dryer, in which the gas stream extends directly in front of and / or behind the heat exchanger plates at an angle to the plane thereof and wherein the ends of the heat exchanger plates around which the gas stream flows are staggered ,
  • the hitherto known heat exchangers or condensers require that during the operation of the condensation dryer for the separation of the water from the moist process air, a cooling air flow is generated and passed through the condenser.
  • the invention is therefore based on the object to provide a capacitor with increased heat exchange performance.
  • the object of the invention is also to provide a condensation dryer with an improved capacitor. Condenser and condensation dryer should also be easy and inexpensive to manufacture.
  • a capacitor housing for a process air stream in a household laundry dryer, wherein at least a portion of the capacitor housing consists of a thermally conductive thin wall.
  • the invention also relates to a condensation dryer with a drying chamber for the objects to be dried, a process air circuit in which there is a heater for heating the process air and the heated process air can be guided by means of a blower over the objects to be dried, and a condenser the water in the moist process air can be condensed, wherein the condenser comprises the aforementioned condenser housing.
  • the thin wall of the capacitor housing has a thickness of from 0.01 to 1 mm, more preferably from 0.03 to 0.3 mm, and most preferably from 0.05 to 0.15.
  • the capacitor 1 according to FIG. 1 has a capacitor housing 2 with a thin thermally conductive wall 3.
  • 4 indicates a bottom plate (bottom plate) of a condensation dryer not otherwise shown.
  • 5 indicates an access for an optional cooling air flow.
  • 6 means a fan in the process air circuit of the condensation dryer, through which the process air is conveyed through a heating and drying chamber of the condensation dryer not shown in FIG. 1 to the condenser block 7 and after the condensation of moisture back into the drying chamber via the heater.
  • the thin wall 3 of the capacitor case preferably has a thickness of 0.01 mm to 1 mm, more preferably 0.03 mm to 0.3 mm, and most preferably 0.05 mm to 0.15 mm.
  • the condensed moisture is generally collected in a condensate collecting vessel, not shown in FIG. Suitable condensate collection vessels are described for example in DE 102 59 343 A1 and DE 199 08 801 A1.
  • the thin wall 3 of the capacitor housing 2 is protected from external influences by the base plate 4.
  • the bottom plate 4 is in contact with the thin wall 3, so that the area available for heat exchange with the outside air is increased.
  • “In contact” here means that the bottom plate 4, the thin wall 3 touches directly or via a particular thermally conductive material Protection of the thin wall 3 is particularly important for very thin walls (use of films) of importance, which have only a low mechanical stability.
  • the thermally conductive thin wall 3 is made of a plastic or a metal, wherein the thickness of the wall is generally lower when using a plastic as a wall material due to the lower thermal conductivity of plastics than when using a metal.
  • plastics can be used numerous plastics.
  • such plastics are used, which either as such, by suitable additives and / or due to a special treatment have an increased thermal conductivity.
  • plastics are preferred which contain elemental carbon and / or metals.
  • metallized plastics are also suitable.
  • "elementary carbon” means in particular graphite or another thermally conductive form of carbon.
  • Numerous metals can also be used as the material for the thin wall 3. Preferred are those with high thermal conductivity. Preferably, steel sheet or aluminum sheet is used. An especially preferred metal used is aluminum.
  • the thin wall 3 is suitably connected to the remaining capacitor housing, for example by welding or gluing. A connection by welding is preferred.
  • the thin wall 3 may be located at different locations of the capacitor housing 2.
  • the thin wall 3 preferably forms at least part of the bottom of the capacitor housing 2.
  • the thin wall 3 of the capacitor may be flat or curved.
  • the thin wall 3 is flat.
  • the capacitor housing 2 generally includes a single thin wall 3.
  • the thin wall 3 consists of several parts, each curved or planar.
  • the thin wall 3 can also form a thinner part of an otherwise thick housing part.
  • the wall plate (or bottom plate 4) of the condensation dryer has a greater thickness than the thin wall 3 of the capacitor housing second
  • the thin wall 3 When using the capacitor housing 2 in a condensation dryer, the thin wall 3 as such may form an outer wall of the condensation dryer. Alternatively, in front of the thin wall 3, there may be a wall plate (e.g., a bottom plate 4) of the condensation dryer which is in contact with the thin wall 3.
  • a wall plate e.g., a bottom plate 4
  • the capacitor housing described here has the advantage of improved heat exchange. Thereby, a condensation dryer with an improved efficiency for the condensation process and thus the entire drying process is obtained.
  • the use of the capacitor housing also allows a condensation dryer, which can dispense with a separate flow of coolant and thus can be made cheaper.
