Description

[0051] Further details and advantages of the invention will be explained in detail with reference to an exemplary embodiment illustrated in the drawing.

[0052] The only FIGURE shows a perspective sectional view of an exemplary construction of a vacuum insulation body according to the invention in the region of the evacuation port. The vacuum insulation body comprises a high-barrier film 10 that encloses a vacuum region which according to the FIGURE extends above the illustrated segment of the high-barrier film 10.

[0053] The arrangement according to the FIGURE also can be provided as such, i.e. as assembly (with or without desiccant or getter 60), and then be vacuum-tightly connected with the further high-barrier film of the vacuum insulation body during the manufacturing process.

[0054] Reference numeral 20 designates the plate or base plate that is fabricated of a material which is resistant to the introduction of zeolite beads when forming the vacuum, so that the beads cannot press into the material of the base plate 20.

[0055] Reference numeral 30 designates a filter fleece, in order to separate the non-illustrated core material which is disposed above the filter fleece and above the high-barrier film from the sorption pump or from the space R. In the space R the adsorbent material 60 is disposed, which can be e.g. zeolite beads or a packing of zeolite beads.

[0056] Reference numeral 40 finally designates the molded part according to the invention, which serves as flow distributor or flow provider from the space to the evacuation port 50. The evacuation port 50 consists of a film tube and likewise is vacuum-tight. Preferably, the evacuation port 50 also consists of a high-barrier film. It suitably is vacuum-tightly connected with the high-barrier film 10.

[0057] As can furthermore be taken from the FIGURE, the flow distributor has an upper plate-shaped portion 41 to which the filter fleece 30 is attached. Furthermore, a lower portion 42 is shown, which is e.g. thermally sealed or otherwise connected with the plate 10. Between the regions 41 and 42 a circumferential region 43 extends, which for example can have the shape of a cylinder piece and which includes apertures through which the gas obtained during evacuation is withdrawn from the space R.

[0058] The plate-shaped portion 41 can be gas-impermeable or also porous or be provided with one or more openings, so that gas can penetrate through the portion 41.

[0059] By using the flow distributor 40, the free flow cross-section in this way can be increased during evacuation with respect to the cross-sectional area of the evacuation port 50 or of the evacuation tube 100 of the vacuum generation unit introduced into the same and thus increase the efficiency during evacuation.

[0060] It can furthermore be seen in the FIGURE that the molded body not only has the task to provide for the evacuation of the space R, but in addition to also form a receptacle for the evacuation tube 100 which is enclosed by the evacuation port 50.

[0061] The region 41 of the flow distributor 40 preferably is gas-impermeable, so that during evacuation the gas gets through the fleece 30 into the space R and from the space R through the openings in the web-like regions 43 to the evacuation tube 100.

[0062] The plate 20 preferably is designed flat. On its inside it adjoins the space R for receiving the adsorbent material and on its outside the high-barrier film 10. The plate 20 provides the arrangement with a certain mechanical stability, provides for the tight abutment of a heating device from outside, i.e. according to the FIGURE from below, and also prevents that flow channels are clogged in that the adsorbent material is pressed in during evacuation. Furthermore, the high-barrier film is protected against being damaged by penetrating adsorbent material.
