Definitions

  • the present invention relates to a vacuum insulation panel.
  • vacuum insulation panels are used in various fields since they have better performance with respect to the conventional insulation materials and since they provide better thermal resistance by using the insulating feature of the vacuum.
  • a vacuum insulation panel is produced by putting a porous core material into a membrane (outer protective envelope) exclusively or together with getter material that retains gas and moisture according to the characteristic of the core material, vacuuming and closing it by providing leak-proofing.
  • the gas pressure is enabled to be decreased by reducing the number of gas molecules in the environment.
  • materials such as precipitated silica, fumed silica, aerogel, fiberglass, open-cell extruded polystyrene and open-cell polyurethane, etc. are used as the core material.
  • the vacuum insulation panel realized in order to attain the aim of the present invention is produced by vacuuming and pressing an open-porous core material placed into a barrier to prevent scattering.
  • the core material of the present invention comprises perlite.
  • the perlite By means of the perlite the particle size of which is adjusted so as to remain between 100 nanometer and 1 micron, the insulation effectiveness of the vacuum insulation panel is improved.
  • the production cost of the vacuum insulation panel is decreased without changing the insulation performance of the vacuum insulation panel by using perlite. Besides by means of using of perlite in the vacuum insulation panels, environment-friendly i.e. green products are realized.
  • a vacuum insulation panel realized in order to attain the aim of the present invention is illustrated in the attached figures, where:
  • Figure 1 - is the schematic view of a vacuum insulation panel of the present invention.
  • the vacuum insulation panel (1) comprises a core material (2) with open porous structure and a barrier (3) that holds the core material (2) together.
  • the open porous core material (2) is filled into a barrier (3) preferably together with a getter material, depending on the material properties forming the core material (2) and vacuumed.
  • a vacuum insulation panel (1) is realized comprising the open porous core material (2) having low thermal conductivity coefficient, with increased insulation effectiveness.
  • the core material (2) of the present invention comprises perlite.
  • the perlite comprises by mass 71 - 75% Si02, 12.8 - 18% A102, 2.9 - 4% Na20, 0.5 - 5% K20, 0.5 - 0.2% CaO, 0.1 - 1.5% Fe203, 0.2 - 0.5% MgO.
  • the production cost is decreased without changing the insulation performance of the vacuum insulation panel by using perlite as the core material.
  • the core material (2) comprises 90%- 95% perlite and 10% to 5% SiC by mass.
  • the SiC in the mixture serves as the opacifier.
  • the core material (2) comprises the perlite, the particle size of which is between 100 nanometers and 1 micron. As the particle size of the porous perlite is deceased, it reaches lower thermal conductivity coefficient values (4.5 mW/m.K-5.5 mW/m.K).
  • the thermal conductivity value of the vacuum insulation panel (1) can be adjusted by changing the particle size distribution and the porous structure of the perlite. As the particle size gets smaller, the thermal conductivity coefficient of the perlite decreases and conductivity of the vacuum insulation panel (1) decreases.
  • the core material (2) comprises perlite with a density between 70 kg/m 3 and 150 kg/m 3 .
  • the density of the vacuum insulation panel (1) can be adjusted by changing the particle size of the perlite during the pulverization process. As the density of the perlite, hence of the core material (2) decreases, the thermal conductivity value of the vacuum insulation panel (1) decreases and the insulation performance is improved.
  • the vacuum insulation panel (1) is suitable to be used inside the door and/or the body of a household appliance.
  • the household appliance is a cooling device.
  • the household appliance is an oven.
  • the household appliance is a laundry dryer
  • the household appliance is a dishwasher.
  • the thermal conductivity of the vacuum insulation panel (1) is reduced, enabling the cooling device (1) to operate more efficiently.
  • perlite instead of polyurethane, the amount of waste polyurethane, that is produced while destroying the used cooling devices (1) and that is destroyed by being burned or buried into the ground, is decreased.

Abstract

La présente invention concerne un panneau isolant sous vide (1) comportant un matériau d'âme (2) avec une structure poreuse ouverte et une structure barrière (3) qui retient le matériau d'âme (2). Le matériau d'âme poreux ouvert (2) est placé dans une structure barrière (3) de préférence conjointement avec un matériau dégazeur, en fonction des propriétés du matériau formant le matériau d'âme (2), et mis sous vide. On réalise ainsi un panneau isolant sous vide (1) comportant le matériau d'âme poreux ouvert (2) qui présente un faible coefficient de conductivité thermique, avec une efficacité d'isolation accrue.
