Definitions

  • the invention relates to bowl-shaped vacuum insulation panels and their use as thermal insulation material.
  • Vacuum insulation panels are usually manufactured according to the following production scheme:
  • a rigid plate made of a porous material - usually made of a rigid plastic foam - is placed in a foil pouch sealed on 3 sides. The 4th side is then sealed in a vacuum chamber.
  • the foil pouch usually consists of a multi-layer foil with the main components: aluminum as a barrier layer and polyethylene as a sealing layer.
  • This process produces high-performance insulation materials that are superior to all other materials in their low thermal conductivity.
  • Cup-shaped, i.e. curved insulation elements cannot be manufactured or only with great difficulty.
  • the use of such shaped insulation elements would be e.g. for the insulation of curved surfaces, e.g. Pipes desirable.
  • the task was therefore to find a method for producing curved vacuum insulation panels.
  • cup-shaped vacuum insulation panels can be produced with excellent dimensional accuracy by using the
  • the invention therefore relates to a method for producing a shell-shaped vacuum insulation panel, in which
  • the plate is sealed on all sides with a gas-tight film in a vacuum chamber
  • the atmospheric pressure acting on the vacuum insulation panel thus produced in accordance with the invention causes the vacuum insulation panel to bend.
  • the radius of curvature of the panel can be calculated precisely in advance by the number and width of the milled grooves.
  • the grooves can e.g. B. be milled with circular saws or grinding wheels.
  • the grooves can have a rectangular or trapezoidal profile (drawing purple +
  • the grooves should preferably penetrate 50 to 75% based on the plate thickness into the plate.
  • the porous plastic plate can consist of polystyrene or polyurethane, for example.
  • the plate preferably consists of porous polyurethane, in particular of polyurethane waste or recycled compressed polyurethane flakes or powder.
  • Another object of the invention is the use of the cup-shaped vacuum insulation panels produced according to the invention as thermal insulation elements, on curved surfaces, for example cooling device doors, the pipe insulation and in cylinder-shaped hot water tanks.

Abstract

L'invention concerne un procédé pour produire un panneau isolant sous vide arqué. Dans ce procédé, a) des rainures droites sont réalisées parallèlement les unes aux autres sur toute la surface d'un côté d'un panneau plat constitué d'un matériau plastique poreux, b) ce panneau est scellé sous vide sur tous les côtés avec un film étanche aux gaz dans une chambre à vide, et c) la pression normale est rétablie dans cette chambre à vide.
