Definitions

  • the invention relates to a plate element for a plate heat exchanger.
  • Such plate elements are customary in the most varied of shapes and made of a large number of different materials.
  • EP-A-2053335 discloses a plate element according to the preamble of claim 1, ie a plate element for a heat exchanger, which is an at least two-layer arrangement, with a layer by means of which enthalpy can be transferred between two fluid flows separated by the plate element, and at least one perforated layer.
  • the invention is based on the object of providing a plate element for a plate heat exchanger which, on the one hand, can be manufactured with little effort, has a comparatively low weight and yet, in addition to the usual heat exchange properties, also has excellent enthalpy exchange properties. In addition to sensible heat or temperature, moisture or water vapor should also be transferred or exchanged between different fluid flows.
  • Such a plate element can be produced with the desired properties with little effort.
  • the membrane layer of the plate element according to the invention can advantageously be configured as a plastic membrane layer.
  • the at least one carrier layer of the plate element according to the invention can be designed as a woven or non-woven layer with comparatively little effort, the selection of the materials mentioned advantageously resulting in the necessarily perforated structure of the carrier layer.
  • the at least one carrier layer of the plate element is formed from a thermally deformable material.
  • this is designed as a three-layer laminate arrangement, with a further carrier layer, which is arranged on the side of the membrane layer facing away from the first carrier layer and by means of which the plate element also has a predeterminable mechanical strength and a spatial structure can be lent and this can be maintained.
  • a planar, punctiform, striped or grid-shaped connection of each carrier layer with the membrane layer can be realized by the material properties of each carrier and / or membrane layer. No additional connecting means, such as adhesives or the like, are then required.
  • the fleece layers can advantageously be configured from a polyester fleece.
  • This polyester fleece should expediently have a weight which is between 20 and 80, preferably about 50 g / m 2 .
  • the polyester fleece can be adjusted hygroscopically.
  • polyester fleece has a coating made of a zeolite and a binder.
  • the enthalpy transmission properties of the plastic membrane layer can be achieved with comparatively little effort if the plastic membrane layer is made from a polymer or polyurethane material.
  • the plate elements described above can be crimped and welded or glued at their edges so that they can be joined together to form a plate heat exchanger with extremely little technical and structural effort.
  • an at least two-layer laminate arrangement of a membrane layer, preferably a plastic membrane layer, and at least one carrier layer, preferably a fleece layer on both sides of the plastic membrane layer, is created in a flat shape, after which this flat Laminate arrangement is provided with the spatial, stable and upright maintainable structure provided for the plate element by means of a single deformation step.
  • those tools can be used which are also used in plate elements made of materials known from the prior art. Therefore, no complex changes etc. to existing production facilities are required.
  • the deformation associated with the production of the adhesive connection takes place by means of pressing at a maximum of 160 degrees C. This ensures that the enthalpy transmission properties of the membrane layer are not impaired.
  • the hygroscopic setting of the carrier or nonwoven layers can be achieved with comparatively little effort by providing the carrier or nonwoven layers with a coating of a zeolite and a binder by means of an immersion or spraying process.
  • the carrier or nonwoven layers Due to the hygroscopic setting of the carrier or nonwoven layers, if a hydrophilic setting of the carrier or nonwoven layers is provided, it can be achieved that water deposited in the carrier or nonwoven layers is evenly distributed over the surface of the carrier or nonwoven layers , whereby the permeability of the plate element is retained as a whole.
  • the plate element 1 shown in the single figure is not to scale in this figure, but only shown in principle. In the embodiment shown in the figure of the panel element 1 according to the invention, this is designed as a three-layer laminate arrangement 1.
  • This three-layer laminate arrangement 1 includes a plastic membrane layer 2 arranged centrally in the laminate arrangement 1, a first fleece layer 3 arranged above the plastic membrane layer 2 in the figure, and a second fleece layer 4 arranged below the plastic membrane layer 2 in the figure.
  • enthalpy can be transferred between two fluid flows not shown in the figure, one of the fluid flows flowing above the plate element 1 and the other of the two fluid flows flowing below the plate element 1.
  • the plastic membrane layer 2 is formed from a polyurethane material in the illustrated embodiment.
  • the first nonwoven layer 3 and the second nonwoven layer 4 are formed from a thermally deformable nonwoven material, in the illustrated embodiment from a polyester nonwoven.
  • the polyester fleece has a weight of 50 g / m 2 .
  • the polyester fleece is designed to be hygroscopically adjustable, for which purpose the polyester fleece is provided with a coating which consists of a suitable zeolite and a binder.
  • the plate element 1 is given a predeterminable mechanical strength and a spatial structure.
  • This mechanical strength and this spatial structure are for the duration of the use of the plate element can be maintained upright in a plate heat exchanger.
  • a flat adhesive connection is provided between the plastic membrane layer 2 on the one hand and the fleece layers 3, 4 on the other hand.
  • this can be realized by means of material properties of the polyester nonwoven forming the nonwoven layers 3, 4 and / or by means of material properties of the plastic membrane layer 2.
  • a flat three-layer laminate arrangement 1 is first created.
  • the plastic membrane layer 2 is placed on the lower fleece layer 4 and the upper fleece layer 1 is placed on the plastic membrane layer 2.
  • the plate element 1 created.
  • the same tools can be used for this process step that are also used in the production of conventional plate elements.
  • these are provided with a coating of a zeolite and a binder, this coating being able to be produced by an immersion or a spraying process.
