Definitions

  • the invention relates to a recuperator comprising a number of neighbouring hexagonal sheets which extend parallel to each other and which are connected to each other at at least a part of their periphery and wherein flow passages are formed between neighbouring sheets.
  • Dutch publication N L 1030270 describes a method for producing a heat exchanger having hexagonal sheets which extend parallel to each other. I n this case, sheets are stacked on top of each other and then neighbouring sheets are connected to each other at their periphery by means of chemical welding, wherein a solvent is used to partially dissolve the material of the sheets at their periphery.
  • a housing is subsequently applied in order to the thus obtained stack of sheets welded to each other, which housing is connected to the stack by means of adhesive bonding.
  • the housing ensures that the dimensions of the thus produced heat exchangers are relatively constant and that the heat exchangers are, for example, interchangeable as a result.
  • the housing provides mechanical protection to the stack and the possibility of attaching the heat exchanger to air supply and discharge lines which communicate with the flow passages between the sheets.
  • each of the sheets, at its periphery, is at least partially surrounded by and connected to an associated connecting body and neighbouring connecting bodies are connected to each other at at least a part of the periphery of the associated sheets and together the connecting bodies form the wall of a housing, wherein passage openings are provided in the wall which are connected to the flow passages for allowing air into the flow passages via the passage openings, wherein neighbouring connecting bodies are provided with protruding parts and with recesses respectively on sides facing each other, wherein the forms of the protruding parts and of the recesses adjoin each other in order to connect the connecting bodies to each other by a press fit.
  • connecting body makes it superfluous to connect sheets to each other directly, for example by adhesive bonding or welding, such as in particular chemical welding or ultrasonic welding. Chemical welding and adhesive bonding have the significant drawback that they (may) require solvents which are dangerous and for this reason extra safety provisions are required.
  • Neighbouring sheets of the recuperator according to the invention are connected to each other via the connecting bodies associated with the respective sheets during production of the recuperator.
  • the connecting bodies which are connected to each other further function as a housing in the sense that they protect the sheets.
  • the connecting bodies can further be formed in order to make attachment to supply and discharge lines possible in a simple manner. It is thus not necessary to use separate housings which are tailor made in advance. This also has the advantage that it is more likely to be cost-effective to produce recuperators in smaller numbers, for example specifically for a certain application or to customer specifications.
  • a correct positioning of the connecting bodies with respect to one another and thus of the sheets can readily be achieved by providing the neighbouring connecting bodies with protruding parts and with recesses respectively on sides facing each other, wherein the forms of the protruding parts and of the recesses adjoin each other in order to connect the connecting bodies to each other.
  • the protruding parts and the recesses may also advantageously be used to produce an airtight or at least substantially airtight connection between the neighbouring connecting bodies.
  • the connection between two neighbouring connecting bodies can be airtight with a high degree of reliability due to the press fit by means of which neighbouring connecting bodies are connected to each other.
  • connection by means of a press fit makes the application of welding or bonding neighbouring connecting bodies to each other superfluous, although it is also possible to combine the clamping connection with a welded or adhesive connection to increase the reliability of the connection.
  • the additional welded or adhesive connection can then, for example, have an extra securing effect.
  • the application, in the event of such a combination, of ultrasonic welding has the advantage that it is then not necessary to use any solvents in any case.
  • a band may also be arranged around the housing, which is optionally connected to each or at least a portion of the connecting bodies.
  • the passage openings are formed between neighbouring connecting bodies.
  • the passage openings are formed by connecting the neighbouring connecting bodies to each other, which enables a relatively simple embodiment of the connecting bodies.
  • the passage openings it is also possible for the passage openings to be formed in, instead of between, connecting bodies.
  • the assembly of the connecting bodies with associated sheets can be facilitated if the protruding parts and/or the recesses have a tapered form or at least partially a tapered form, as a result of which it is possible to realize a self-aligning positioning.
  • a practical embodiment at least during assembly and optional disassembly, can be obtained if neighbouring connecting bodies are connected to each other by means of a click-fit connection.
  • recuperator is provided with a sealing body between neighbouring connecting bodies at the location where they are connected to each other, wherein it may be further preferred, with a view in particular to achieving a simple assembly, for the sealing body to be connected to one of the two neighbouring connecting bodies.
  • the invention is suitable, inter alia, for recuperators of the membrane type.
  • the sheets of such recuperators are suitable for exchanging moisture.
  • the material of such sheets is not suited or is poorly suited to being welded.
  • the use of adhesive for connecting membrane sheets to each other has the drawback that this is a step which is difficult to control and, partly as a result thereof, expensive, particularly if recuperators are produced in relatively large numbers, and that, depending on the type of adhesive that is used, it also involves the use of harmful solvents. Therefore, at least a portion of the sheets of a recuperator according to the invention may advantageously be permeable to moisture.
  • the recuperator may be configured to have sheets which are all provided with a profile.
  • the connecting bodies can contribute to a correct positioning of the sheets, more specifically the profiles thereof, with respect to each other, since the sheets can behave in a relatively stiff way owing to the connection with the connecting bodies.
  • the invention is also suitable for a more traditional way in which sheets can be provided in a recuperator, namely wherein the neighbouring sheets are flat and are provided with a profile in an alternating fashion.
  • the recuperator according to the invention may also advantageously be used if sheets are made of different materials, for example if neighbouring sheets are made of different materials in an alternating fashion.
  • An advantageous application of the invention may be in recuperators wherein a portion of the number of sheets is made of a moisture-permeable material and the other portion of the number of sheets is made of a material which is not permeable to moisture. In traditional recuperators, such materials are difficult to combine.
  • connecting bodies In order to produce a good connection between a connecting body and an associated sheet, it may be preferred, in the event that sheets made of different materials are used, for the connecting bodies to be made of different materials. In this case, a fixed combination is formed of the material of the connecting body and the material of the associated sheet.
  • each of the sheets is at least substantially, including also completely, surrounded by an associated connecting body.
  • connecting bodies may be injection moulded, particularly in the case of relatively large production numbers.
  • the periphery of the housing is bar-shaped.
  • the bar shape of the housing facilitates the attachment of other parts, such as in particular air ducts, to the recuperator.
  • the invention provides the possibility of providing the housing with a bar-shaped periphery in a simple manner, namely by adapting the design of the connecting bodies hereto.
  • Bar-shaped is understood to mean all forms in which six main surfaces are connected to each other at right angles. The definition of bar-shaped therefore also includes the form of a cube.
  • the connection between the sheet and the connecting body can be produced directly during the injection moulding.
  • the sheets are over-moulded with the material of the connecting bodies along the first part of the periphery of the connecting bodies during the injection moulding of the connecting bodies at the periphery of the sheets.
  • the invention therefore also relates to a method for producing a connecting body for use in a recuperator according to the invention, the method comprising the following steps closing a mould, wherein a mould cavity is formed and a sheet is positioned in the mould cavity at at least a part of the periphery of the sheet,
  • the invention further provides a method for producing a recuperator according to the invention, the method comprising the following steps
  • encircling connecting bodies each having a sheet that is connected to the associated connecting body and extends on the inside of the encircling connecting body
  • connecting connecting bodies to each other by a press fit in such a way that flow passages are formed between neighbouring sheets associated with neighbouring connecting bodies.

  • Clamping layers 2a and 2b on top of one another may be done manually but optionally also in an automated manner, for which purpose a relatively simple assembly machine may be sufficient. This machine may be suitable for heat exchangers of different dimensions, with no or only limited re-setting being required.
  • Figures 4a to 4c show successive steps of an alternative method for producing a layer 2, wherein, after solidification of the plastic material as explained with reference to Figures 3a to 3e, an extra mould cavity 26 is formed at the underside of the connecting body 3 by moving injection duct body 27, which extends over the entire length of groove 16, downwards with respect to the bottom mould body 23'. Subsequently, liquid plastic material is supplied to the extra mould cavity 26 via injection duct 28 in injection duct body 27.
  • the material of this plastic differs from the plastic material in mould cavity 24 in the sense that it behaves resiliently in solidified form, like a rubber. After solidification of the plastic material in the extra mould cavity 26, it is adhered to the plastic material in mould cavity 24 and forms a seal 29.
  • layer 2a' The product thus produced is denoted as layer 2a'. It is of course also possible to provide layer 2b with a seal in a similar way as seal 29. This layer is denoted by reference numeral 2b'.
  • the seal 29 serves to promote an airtight attachment of neighbouring layers 2a', 2b' ( Figure 4e).

Abstract

L'invention concerne un récupérateur comprenant un certain nombre de plaques hexagonales voisines qui sont reliées les unes aux autres. Des passages d'écoulement sont formés entre des plaques voisines. Chacune des plaques, à sa périphérie, est au moins partiellement entourée par un corps de liaison associé et reliée à celui-ci. Des corps de liaison voisins sont reliés les uns aux autres au niveau d'au moins une partie de la périphérie des plaques associées et forment ensemble la paroi d'un logement. Des ouvertures de passage sont ménagées dans la paroi et sont reliées aux passages d'écoulement pour permettre à l'air de s'écouler dans les passages d'écoulement par les ouvertures de passage. Des corps de liaison voisins sont pourvus de parties en saillie et d'évidements respectivement sur des côtés opposés, les formes des parties en saillie et des évidements étant adjacentes les unes aux autres afin de relier les corps de liaison par un ajustement par pression. L'invention concerne en outre des procédés de fabrication d'un corps de liaison et d'un récupérateur.
