Definitions
- the subject of this invention is a method of manufacturing a vacuum thermal insulation board.
- Some insulating panels have the constitution of Figure 1, namely an insulating lining 1 enclosed in a casing 2 usually formed of a lower sheet 3 and an upper sheet 4, at least one of which is folded around the lining 1 in order to adhere to the other leaves.
- a weld 5 is established between the portions near the edges of the sheets 3 and 4 to isolate the volume they include and the lining 1 from the outside.
- the panel can then be inserted behind a shield to form a heat shield. He who is represented is plane but he can be cylindrical or of another form.
- An insulating material commonly used for the liner 1 is a so-called microporous, that is, an agglomerated powder of a material such as silica.
- the sheets 3 and 4 are generally composed of two layers of polyethylene between which an aluminum layer is interposed to increase the strength and sealing of the sheets. Welding therefore concerns the polyethylene layers and is easily carried out.
- FIG. 1 already described illustrates a thermal insulation panel to be constructed
- FIG. 2 represents the panel by explaining the steps of the manufacturing process
- FIG. 3 illustrates the suction device
- FIG. 4 is a detail of the wedge used, - and Figure 5 illustrates a welding tool.
- FIG. 2 is discussed.
- two more superposed sheets 3 'and 4' will be used to enclose an internal volume comprising the lining 1, but the lower sheet 3 'like the top sheet 4 'will now be provided with an appendix 6 on one side of the panel, opened by a hole 7 giving in the interval leaves 3' and 4 'and indirectly in the volume of the lining 8.
- a first weld 8 is executed in a closed contour surrounding the lining 1 and the hole 7, thus passing through the outer edge of the appendix 6.
- FIG. 3 illustrates the suction method used.
- a vise 11 clamps the appendix 6. Its upper jaw opening on the hole 7 is hollow and comprises a conduit 12, opening in front of the hole 7 and leading to a vacuum pump 13.
- the sheets 3 'and 4' are maintained at a sufficient clearance by a hold
- the wedge 14 slipped between them and prevents Appendix 6 from curling up.
- the wedge 14 is provided with grooves
- 3 'and 4' sheets of stainless steel, titanium or low-alloy nickel were used. These metals have given good results. Their alloys, and possibly other metals, may be suitable.
- FIG. 5 represents a possible device, in which two wheels 16 and 17 both dependent on an arm 18 shown in a diagram are arranged facing each other so as to be in contact with the sheets 3 'and 4', respectively.
- the wheels 16 and 17 roll under and on the envelope when the arm 18 pull them. They are both connected to an electrical circuit 19 which imposes a potential difference heating Joule by the effect of the stack of sheets 3 'and 4' located between them.
- the energy is sufficient to produce a melt 20 between the rollers 16 and 17 and a weld bead 21 upon solidification.
- knobs 16 and 17 could also be replaced by a fixed counter-electrode resting on the sheet concerned or on the support of the envelope; it would also be possible to arrange the knurls 16 and 17 side by side, transversely or longitudinally, on the same sheet 3 'and 4', and the melt would still develop between the two sheets 3 'and 4' and between the knurls 16 and 17.
- These design variants belong to the art of knurling.
