Definitions

  • the invention relates to a card for the construction of permeable structures, in particular for the construction of cross-flow heat exchangers.
  • Cards of the type mentioned made of ceramic material and permeable structures made therefrom are known from DE-A-36 43 750.
  • the known cards have first recesses which form continuous channels in the case of stacked cards.
  • Second recesses are arranged around the first recesses in such a way that the second recesses of adjacent cards partially overlap, channels being formed which extend perpendicularly to and surround the continuous channels.
  • the large flow resistance in the channels, which are formed by the second recesses, is disadvantageous.
  • the invention seeks to remedy this.
  • the webs remaining between the holes in a row of holes and a row of holes and the recesses can be 1 to 10 mm wide, the recesses 1 to 50 mm.
  • the cards are stacked alternately by turning around the axis of symmetry defined by the middle row of holes and about the perpendicular thereto, the holes forming continuous channels in stacked cards and the recesses forming flat channels which extend substantially across the continuous channels.
  • the holes can be of any geometric shape, e.g. circular, oval, triangular to polygonal.
  • the advantages of the invention can be seen essentially in the fact that by varying the web length between the card edge and the longest recess or the second longest and shortest recess by up to + 6%, the media exchange between adjacent flat channels can be variably designed or prevented. In addition, the flow resistance is reduced because the flat channels form continuous slots.
  • the permeable structure can be built from a map pattern.
  • Structures for several media flowing in parallel can also be built up by designing the end foils. 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 holes 2 of a row of holes are spaced 1 to 10 mm apart, i.e. the webs 8 remaining between them are 1 to 10 mm wide.
  • Recesses 3, 4, 5 of different lengths are arranged between the rows of holes.
  • the recesses are 1 to 50 mm wide and have a distance (web 9) of 1 to 10 mm to the rows of holes. All recesses start at the edge of the card, ie they cut it. The longest recess 3 and the second longest recess 4 intersect the same card edge 10. The shortest recess 5 is arranged opposite the second longest and intersects the card edge 11. The length of the webs remaining between the recesses 4 and 5 and between the recess 3 and the card edge 6.6a is 25% ⁇ 0 to ⁇ 6% of the card length in the direction of the rows of holes. According to FIG. 1, the length of the webs 6.6a is 25%, according to FIG. 2 approximately 20% of the card length.
  • Green cards made of ceramic material cannot be made in any thickness. By laminating individual cards together, plates and blocks can be produced are, which then each have a multiple of the card thickness. Subsequent firing turns the laminated block into a homogeneous ceramic component. In addition to ceramic material, metal sheets or plastic films can also be used for the punched cards.
  • the surface area ratio of perforated channels to flat channels can be influenced by these design variants.
  • the area and channel cross-section on the hole side always remain constant.
  • the area and channel cross-section of the flat channels can, however, be varied by arranging several cards in the same position.
  • the total cross-section flowed through always remains the same on the side of the flat channels.
  • the stacking of single cards gives the largest area ratio.
  • a stack of, for example, five cards 1 in the same position reduces the area of the connecting webs 6, 6a to 1/5 and increases the individual channel cross-sections to five times with a constant cross-sectional area and constant conditions on the hole side. This means that in the case of heat exchangers with the same external dimensions, the area ratio can be varied in a simple manner and thus adapted to the requirements.
  • the holes 2, in any shape and number, are arranged on the card in such a way that when the card 1 is turned, they always coincide with the holes 2 of the card above or below (FIG. 4).
  • the stacking sequence (FIG. 3), through which the structure is permeable to the second medium, has a rhythm of four.
  • One or more identical cards 1 are brought into layers A, B, C and D and laminated on top of each other in this position and sequence. This means that a certain card corner - indicated by a plus sign - comes to rest on all four stacking corners one after the other.
  • So card B is created by turning card A around Axis of symmetry, card C by turning card B around the perpendicular to the axis of symmetry and card D by turning card C around the axis of symmetry (FIG. 3).
  • the four-card stack is repeated until the desired block height is reached.
  • the block can be completed by a cover card that only contains the rows of holes.
  • the card 1 described can be combined into larger units in both the longitudinal and transverse directions.
