Definitions

  • the invention relates to a Kondu irritationstragISE and a method for its preparation, with means for passing a medium having a flat metal foam core having two flat sides and at least one end face, wherein on the flat sides in each case at least one Flachtimedeck für and on the at least one end face at least one end face cover layer arranged and with the metal foam core cohesively fluid-tight manner, and wherein the Flachputdeck füren and the at least one Stirnitendeck slaughter the metal foam core on all sides, wherein the metal foam core closed cells and at least on a flat side fluid channels forming embossed recesses as means for passing the medium and wherein the recesses of the flat side of the metal foam core overlapping flat side cover layer are closed to the outside.
  • One-piece plate-shaped supporting bodies are known as sandwich constructions with a homogeneous core of foamed materials, in which the foam core is arranged as a middle layer between two cover layers of the same or different material. The three layers are firmly connected.
  • the aim of sandwich constructions is to save on Material and weight to achieve improved carrying capacity over the starting materials.
  • Both the topsheets and the core layer of such a construction must accommodate different forces and stresses and are therefore suitably matched to one another.
  • the foam core has the main task to keep the two cover layers at a distance and thereby absorb appropriate forces.
  • the foam core has the task to ensure a shear transfer between the cover layers, as well as to stabilize the cover layers against buckling and buckling.
  • the deformation stiffness of such a sandwich plate increases with increasing shear strength of the core.
  • the cover layers also have the task to absorb the bending moment in the form of a pair of forces, that is both tensile and compressive forces.
  • the foam core As material for the foam core and the two cover layers, metal or plastic is often used due to the favorable weight-stability-price ratio. It has proved particularly expedient to form the foam core forming the middle layer with closed cells of corrosion-resistant metal, for example aluminum, open cells being also possible. Such a cell structure is generally only very thinly laminated on both sides with aluminum sheets, wherein the height of the flat metal foam core essentially determines the thickness of such an aluminum support body. Such aluminum support body have an extremely high mechanical stability at very low weight and also have a high conductivity.
  • conduction also called heat conduction or heat diffusion, is understood in physics as the heat flow in a solid or in a fluid at rest due to a temperature difference.
  • Aluminum support bodies are used as essentially two-dimensional or as three-dimensionally shaped components, for example in aircraft, automobile, caravan, ship and boat construction.
  • the primary technique for producing closed-cell aluminum foam is based on aluminum powder and a metal hydride, for example titanium hydride. Both powders are mixed together and then compacted by hot pressing or extrusion to a starting material, which is then heated to a temperature above the melting point of aluminum.
  • a metallic support body as described above, is outstandingly suitable for constructing a Konduktionstragêt stresses for a heating or cooling panel. Further fields of application for metallic foams are heat shields, thermal encapsulations, filters or sound-absorbing cladding.
  • the publication DE 2010 013 734 A1 discloses a device for cooling and a method for its production.
  • the proposed device in the manner of a cooling plate comprises open-pore metal or plastic foam, which is plate-shaped and has a top, a bottom and front sides, wherein the foam is surrounded by a jacket of fluid-tight film-like material.
  • the jacket has at least one inflow and one outflow and consists of cover plates for the flat sides and side parts for the end faces of the foam core.
  • the open pores of the foam core form continuous channels through which a fluid can flow.
  • the foam core which is preferably made of metal such as aluminum, a heat exchange between the foam material and the fluid passed through takes place.
  • the fluid can enter analogously to a sponge on one side of the foam material and exit on an opposite side, where the inflow and the outflow are arranged.
  • a disadvantage of the known heat exchanger is considered that the metallic foam core is open-pore, that is, that it has open cells formed and that it lacked incorporated fluid channels. Due to the non-existent fluid channels in connection with the unfastened cell structure of the metal foam core, the fluid flows through the entire metal foam core with high flow resistance. Thus, on the one hand, although a strong turbulence of the fluid, that is, a good heat transfer between the foamed metal core and the fluid achieved, but on the other hand, the flow rate of the fluid reduced so that the heat transferring to the fluid is not sufficiently dissipated. Accordingly, the performance of the cooling device is limited.
  • the solar collector has at least one absorber surrounded by a housing made of a metallic, crosslinked 3-D structure.
  • the structure preferably consists of open-pored or closed-pore metal foam made of aluminum or an aluminum alloy.
  • the absorber is covered with a transparent disc which is part of the thermally insulated housing, the absorber and the disc being separated by an air gap. The absorber is flowed through by a heat transfer medium.
  • the aim of the present invention is to overcome the above-described disadvantages of the prior art.

Otherwise, when the flat sides are formed as a polygon, the metal foam core has a certain number of corner numbers of rectangular rectangular end faces, on each of which an associated identical end face cover layer is arranged.
  • the central idea of the invention is to reduce the flow resistance in the Kondu VietnamesestragISE by providing defined fluid channels are provided in the metal foam core.
  • the medium conducted through the conduction support body for heat transport should flow only in the intended fluid channels and not branch into the adjacent cells of the metal foam core.
  • a metal foam is used for the metal foam core having closed cells. Due to the high thermal conductivity of the metal foam core with the closed cells, the heat exchange between the flat sides, the Flachcrowdeddeck füren and the flowing medium of the Kondutechnischstrag emotionss is not affected.
