Definitions

  • the invention relates to a permeable structure which is constructed from cards to form a stack of cards and in which continuous channels are arranged in rows and flow spaces are formed between the rows of channels and are delimited by cover plates on opposite sides in the stacking direction.
  • cards made of green ceramic, metal, such as Alloys made of copper, steel, aluminum or plastic can be understood.
  • Permeable structures of the type mentioned made of ceramic are known from DE-A 40 226 54. These structures have rows of holes running parallel to one another, between which channels are arranged, which are provided in alternating sequence with uniform and regularly arranged webs. When using the structures as a heat exchanger, the heat exchange takes place via these webs.
  • the invention aims inter alia significantly improve the heat transfer and identify means for controlling the heat transfer.
  • the advantages of the invention can be seen essentially in the fact that the heat exchange and the fluidization in the flow spaces can be influenced by varying the length of the webs.
  • the Individual cards for building the structure can be cut from an endlessly producible card, whereby the pattern of the individual cards can be varied, so that at least 3 to 20 different card patterns can be used for its construction within the permeable structure.
  • Structures for several media flowing in parallel can also be constructed by designing the cover plates or using blind cards. By deviating the hole centers from the common hole row axis, structures can be built up in which the channels formed by the holes are given a step-like to helical surface.
  • the continuous channels 1, which are created by stacking the cards 2, are arranged in rows 3.
  • Flow spaces 4 are formed between the channel rows 3 and are delimited on opposite sides by (covers) cover plates 5.
  • at least two transverse webs 6 are arranged on the same card level, the transverse webs 6 having a different length "B" in at least half of the cards.
  • the arrangement of the crosspieces 6 in the flow spaces 4 can be made as desired according to the requirements for heat exchange and media swirling.
  • the channels 1 extend essentially perpendicular to the flow spaces 4 and can run in a straight line and parallel to one another. By deviating the holes 7 (hole centers) in the individual cards 2 from the channel axes, step-shaped or helical channel surfaces can be generated.
  • the channels 1 can also be arranged in any shape and arrangement with respect to one another be.
  • the individual channels 1 can have a constant or variable cross section over their length and / or with one another (FIGS. 4 and 5).
  • the first channel 1a (hole 7a, FIG. 3) of a row 3 can have a larger cross section than the other channels 1 which form the row 3 and which are partially surrounded by the flow spaces 4a.
  • the width "A" of the flow spaces 4 can be constant or vary in the flow direction (FIG. 4).
  • the flow spaces 4 can also have further obstacles of any design, such as deflection plates etc. (not shown).
  • the transverse webs 6a on the edge can be provided with ribs 8 (FIG. 2).
  • the channels 1 of a row 3 can be connected to one another and / or to adjacent channel rows 3 by appropriate design of cavities in the cover plates 5, which can be constructed from any number of cards 2 (not shown). Corresponding connections can also be created by installing special intermediate cards or layers of cards (not shown). The same also applies to the flow spaces 4.
  • the channels 1 and the flow spaces 4 can be constructed from differently cut maps (FIG. 4).
  • FIG. 4 which shows a section of an endlessly producible card band, shows the cut lines for the cards 2a, 2b, 2c, 2d.
  • the cover plates can have openings 9 or collecting channels (not shown) for the channels 1 and can be provided with an attached frame 11, which saves the grinding of the entire cover plate surface.
  • the wall thicknesses "W" can be varied between the channels 1 and / or the flow spaces 4. Corners and edges can be rounded.
  • the transverse webs 6 and walls 10 between the channel rows 3 and the flow spaces 4 can be provided with closed, inaccessible hollow chambers or with cavities which can be flowed through or through one or a few openings (not shown).
  • the cards can be connected by lamination with subsequent firing, by soldering, welding, gluing or mechanically (eg using a tie rod) with the interposition of seals.
  • the cards 2 with the breakthroughs can be produced by casting, sawing, milling, turning, deep drawing, embossing, lasering, punching or liquid jet cutting.
  • heat exchangers for heating devices, in particular for condensing heating devices and waste heat boilers for the heat exchange gas / gas, gas / liquid or liquid / liquid media, as well as for burner designs with gaseous or liquid fuels.
