Definitions

  • the invention relates to a layer heat exchanger with a layer block for guiding a first fluid flow adjacent to a second fluid flow and a housing surrounding the layer block.
  • Heat can be transferred from the first fluid stream to the second fluid stream via layer heat exchangers.
  • the fluid streams can be guided adjacent to each other.
  • the object of the invention is to provide an improved layer heat exchanger, in particular with an improved temperature change stability.
  • the object is achieved with a layer heat exchanger with a layer block for guiding a first fluid stream adjacent to a second fluid stream and a housing surrounding the layer block in that between the layer block and the housing, a decoupling device for mechanical decoupling and floating mounting of the layer block is arranged in the housing.
  • a decoupling device for mechanical decoupling and floating mounting of the layer block is arranged in the housing.
  • the layer block at high temperatures, for example of up to 900 ° C or higher, more expands than the surrounding housing.
  • Such a temperature behavior basically leads to alternating temperature voltages.
  • these temperature change voltages can be absorbed by the decoupling device and reduced to a minimum.
  • the forces transferred from the layer block to the housing can be reduced so much that a mutual destruction of the layer block and the housing, in particular bending of the housing, are excluded.
  • the layer block is thus separated from the housing by the decoupling device or floatingly mounted in the housing. Different thermal expansion coefficients can thus be compensated, so that, for example, advantageous for the layer block materials with a greater thermal expansion than the housing - or vice versa - can be used.
  • a preferred embodiment of the Schichtebenschreibtragers is characterized in that the decoupling device has elastic properties. Due to the elastic properties, the different strains can be compensated elastically reversible.
  • a further preferred embodiment of the Schichtebenschreibtragers is characterized in that the decoupling device comprises mineral fiber mats.
  • Mineral fiber mats advantageously have a high temperature resistance and elastic properties and can therefore advantageously be arranged between the housing and the layer block.
  • a further preferred embodiment of the Schichtebenschreibtragers is characterized in that the decoupling device comprises molded wire mesh.
  • these wire knits are filled with fillers, in particular with minerals, graphite, glass or glass composites in order to increase the sealing function.
  • the decoupling device of an amorphous solid such as Glass exists or a glass-matrix composite material.
  • the material can of course be suitably pressed.
  • Glass-matrix composite material is understood according to the invention to mean a material having a glass as the base material, in which ceramic particles, fibers or the like, for example of ZrO 2 or YSZ, or metallic particles, fibers or the like, for example of Ag, are incorporated.
  • Important parameters for adjusting the viscosity and the thermal expansion coefficient of the glass matrix composite material are the glass transition temperature of the glass matrix base material and the amount and type of ceramic or metallic particles or fibers. A common value is the addition of about 10 percent of particles or fibers.
  • a further preferred embodiment is that in order to increase the tightness, the decoupling device is covered with a sealing foil, for example a metal foil.
  • a sealing foil for example a metal foil.
  • a variant of this embodiment is to incorporate into the decoupling device, the sealing film, for example, in that a sealing foil is inserted into a mineral fiber mat.
  • a further preferred embodiment of the Schichtebenschreibtragers is characterized in that the decoupling device has a positive connection between the housing and the layer block.
  • the decoupling device can be clamped between the housing and the layer block.
  • the positive connection between the housing and the layer block can advantageously ensure exact positioning of the layer block within the housing.
  • an exact relative positioning of the decoupling device to the rest of the housing can be ensured via the positive connection, for example for assembly purposes.
  • a further preferred embodiment is characterized in that the layer block is not thermo-mechanically separated all around by the decoupling device in the housing, but only locally at locations which have a particularly high temperature.
  • the page the Schichtissestedtragers via which the heated and therefore cool medium supplied to the layer block will be connected via a welded or soldered connection firmly with the housing.
  • the thermal expansion of the layer block is then absorbed by the remaining coupling elements.
  • the advantage of this embodiment is that a transfer of a medium from one side to the other by means of bypassing by the decoupling device is reduced, since the weld or Lötglagenaht is usually gas-tight.
  • a further preferred embodiment of the Schichtebenschreibtragers is characterized in that the positive connection has two oppositely arranged trough-shaped cover plates and U-profiles.
  • the material fiber mats of the decoupling device can be inserted in a form-fitting manner into the trough-shaped cover sheets.
  • a further preferred embodiment of the Schicht Vietnamese agostedtragers is characterized in that the housing has the U-profiles associated lid and four manifolds for guiding the fluid flows. About the collection boxes adjacent fluid streams can be added to the layer heat exchanger each and again discharged. About the U-profiles and the lid, a substantially cubic or cuboidal structure can be generated. The U-profiles and the covers are components of the housing of the Schichtissestedtragers.
  • Figure 1 shows a portion of a Schichttownauertragers 1, wherein in a three-dimensional view obliquely from above a housing 3 with a total of four headers 5 an upper lid 7, a lower lid 9 and a total of eight U-profiles 11.
  • the eight U-profiles 11 are between the upper lid 7 and the lower lid 9 are arranged so that the lower lid 9 is arranged parallel to the upper lid 7.
  • FIG. 2 shows the housing shown in Figure 1, but without the headers 5. As a result, the lower lid 9 is visible. It can be seen that the lower lid 9 associated with a trough 13.
  • the U-profiles 11 are arranged so that they are U-shaped opening in the direction of the interior of the housing 3, wherein each two of the U-profiles 11 are associated with each other fluid-tight.
  • FIG. 3 shows a three-dimensional view from above of a layer block 15.
  • the layer block 15 can be arranged within the housing 3 in such a way that a first fluid flow 16 adjacent to a second fluid flow 18 can be guided by means of opposite collecting tanks 5.
  • the fluid streams 16 and 18 can thus be performed in crossflow.
  • the layer block 15 has inlet and outlet surfaces 17. These are limited by 2 x 4 welded and / or soldered surfaces 19.
  • the surfaces 19 are bounded by an upper cover plate 21 and the lower cover plate 13 above and below.
  • the layer block 15 has fluid paths, not shown in more detail, which are constructed to guide the fluid streams 16 and 18 adjacent to one another.
  • the layer block 15 shown in FIG. 3 can be stored floatingly within the housing 3 of the layered heat exchanger 1 by means of a decoupling device 25 shown in FIGS. 4 and 5 in a mechanically decoupled manner.
  • Figure 4 shows a side view with a half-section of the housing 3 of the Schichthoffauertragers 1.
  • Figure 5 shows a cross section in the corner, wherein two of the U-profiles 11 and schematically indicated the layer block 15 are shown in section.
  • the decoupling device 25 has two mineral fiber mats 27, wherein an upper mineral fiber mat 27 is visible in Figure 4 in half section of the housing 3. The mineral fiber mats 27 are positively inserted into the cover plates 21 and 13.
  • the particular all-round thermal expansion of the layer block 15 is indicated. It can be seen that this thermal expansion of the layer block can be absorbed by the mineral fiber mats 27 and 40 before they can penetrate onto the covers 7 and 9 of the housing 3. The layer block 15 is thus stored mechanically decoupled within the housing 3 via the mineral fiber parts 27, 40, 25 and 31. Furthermore, it can be seen that the mineral fiber mats 27 are inserted in a form-fitting manner in the trough-shaped cover plates 21 and 13. Consequently, the layer block 15 is additionally accommodated in a form-fitting manner within the housing 3. The cover plates 21 and 13 may be assigned to the layer block 15. A cohesive connection, which could lead to increased temperature AC voltages, is therefore not necessary.
  • FIG. 5 shows a further detail of the decoupling device.
  • the decoupling device consists of the eight U-profiles 11, the two cover sheets 7 and 9 and the mineral fiber parts 27, 40, 25 and 31.
  • the U-profiles 11 visible mineral fiber strips 31 are introduced in section. These are thus fixed in a form-fitting manner in the U-profiles 11.
  • the mineral fiber strips 31 are dimensioned so that they strike elastically resiliently on the layer block 15.
  • the thermal expansion of the layer block 15 in the direction of the plane of the figure 5 is indicated. It can be seen that this direction of elongation of the layer block 15 is transmitted to the U-profiles 11 of the housing 3 via the mineral fiber strips 31 of the decoupling device 25.
  • the layer block 15 is also in the dimension of the image plane of Figure 5 form-fitting, elastically resilient, floating. The thermal expansion of the layer block 15 thus does not strike directly on the U-profiles 11 of the housing 3.
  • the layer heat exchanger 1 is thus advantageous for high temperature differences, for example up to 900 ° C and higher, as they can occur between the first and second fluid flow designed.
  • the decoupling device 25 can effectively counteract increased wear.
  • the decoupling device 25 prevents the occurrence of high temperature stresses between the layer block 15 and the housing 3.
  • a failure of the Schichthoffübertragers 1 can be prevented so effectively.
  • All parts of the housing 3 are mechanically decoupled from the layer block 15. It can therefore be stored without a cohesive, so only by the positive connection of the layer block 15 within the housing 3. Thus, it is effectively prevented that the housing 3 and the layer block 15 can mutually destroy each other by temperature change voltages.
  • connection of the collecting boxes 5 to the U-profiles 11 can be made fluid-tight.
  • the mineral fiber strips 31 can be mounted with respect to the layer block 15 under a certain pretension This results in the smallest possible leakage between the first and the second fluid streams 16 and 18 conducted via the layer block 15.
  • the mineral fiber mats 27 shown in Figure 4 can be mounted under a certain bias between the covers 7 and 9 and the cover plates 21 and 13, so that there is also the smallest possible leakage current.
  • the layer heat exchanger 1 has a three-part or three-shell structure, from the inside to the outside with the layer block 15 and optionally its cover plates 21 and 13, the mineral fiber mats 27 and 40 and the mineral fiber strip 31 of the decoupling device 25 and the covers 7 and 9 and the U Profiles 11 of the housing 3 as a third layer.
  • the middle shell of the decoupling device 25 may comprise a high-temperature-resistant mineral fiber fleece.
  • the mineral fiber web as a so-called “swelling mat”, for example as mineral fiber with vermiculite.
  • this can reversibly stretch at high temperatures and thus bias the layer block 15 against the housing 3.
  • the U-profiles 11 bias the mineral fiber strips 31 in two directions.
  • the U-profiles 11 can be connected to each other under bias, preferably welded to welds 35, be.
  • the U-profiles 11 can be welded together fluid-tight at the corner.
  • the U-profiles 11 can be fluid-tight welded to the manifolds 5 at welds 37.
  • the U-profiles 11 at welds 39 fluid-tight with the upper and lower cover 7, 9 of the housing 3 can be welded fluid-tight.
  • the decoupling device 25 or the mineral fiber mats 27 and 40 and the mineral fiber strips 31 can compensate for a thickness of between 0 and 20 mm in an elastically distanced manner, and thus absorb differences in temperature expansion.
  • the layer block 15 of the Schichtebenesttragers 1 is thus mounted by means of the decoupling device 25 floating on all sides in the sealed over the welds housing 3 so that the thermal expansion of the layer block 15 can act practically non-deforming on the housing 3.
  • voltage peaks can be reduced and therefore the thermal resistance of the layer heat exchanger 1 can be increased.
  • any internal leaks may be minimized and / or reduced to zero.
