Description
FLEXIBLE VACUUM INSULATION PANEL AND
METHOD OF MANUFACTURE
This invention relates to flexible vacuum insulation panels and their manufacture.
Vacuum insulation panels are of great interest for providing highly efficient thermal insulation performance particularly at relatively low temperatures in a range from -50 degrees to 50 degrees Celsius.
A vacuum insulation panel normally comprises a lightweight core in the form of a rigid foamed plastics or a compacted powder or fibrous material. One or more of these materials is contained within a low permeability envelope which is evacuated and sealed to form a rigid panel.
Special envelope materials have been developed to inhibit penetration by gases and water vapour which would otherwise soften the vacuum and reduce the insulation efficiency.
These envelope materials, or barrier bags, are usually in the form of a laminate construction with each layer fulfilling a particular function.
Vacuum insulation panels have an inherent rigidity due to the action of the evacuation of the core and the resulting formation of a constrictive outer layer in the form of the enveloping barrier bag. However, some applications, for example for large tanker vehicles, require vacuum insulation panels to have a degree of flexibility to enable the panel to fit a contoured surface.
It is therefore an object of the present invention to provide a flexible vacuum insulation panel and method of manufacture which overcomes or minimises this problem.
According to one aspect of the present invention there is provided a flexible vacuum insulation panel comprising a core having first and second major faces and comprising a plurality of core members of thermal insulation material arranged substantially side-by-side between the first and second major faces, a first envelope enclosing the core members, and means interconnecting material of the first envelope at the first and second major faces of the core along a line intermediate adjacent core members; and a second envelope enclosing the core, the arrangement being such that the vacuum insulation panel is capable of flexing along the line intermediate adjacent core members. - 3
According to another aspect of the present invention there is provided a method of manufacturing a flexible vacuum insulation panel comprising the steps of: producing a core having first and second major faces and comprising a plurality of core members of thermal insulation material arranged substantially side-by-side between the first and second major faces, the core members being enclosed within a first envelope with means interconnecting material of the first envelope at the first and second major faces of the core along a line intermediate adjacent core members; enclosing the core in a second envelope; evacuating the second envelope; and sealing the evacuated second envelope, the arrangement being such that the vacuum insulation panel is capable of flexing along the line intermediate adjacent core members.
The first envelope may comprise a polymeric material, for example woven or non-woven polymeric material. The non- woven polymeric material may be non-woven polyester.
The first envelope may comprise woven glass material. - 4
The second envelope may be in the form of a laminate construction and may be manufactured from more than one laminate construction.
The core members of thermal insulation material may comprise one or more materials selected from powders, fibres, moulded insulation materials and pre-cast insulation shapes.
The powders may be in the form of compacted powders.
The powders may include a microporous matrix which may include an opacifier.
The compacted powders may be reinforced with fibres.
The core members may comprise finely divided silica having a large surface area.
The finely divided silica may be compacted to a density sufficient to withstand air pressure applied to a surface of the panel.
The interconnecting means may be in the form of stitching through the material of the first envelope at the first and second major faces of the core. - 5
The interconnecting means may be applied to the first envelope material before the core members have been provided within the first envelope.
For a better understanding of the present invention and to show more clearly how it may be carried into effect reference will now be made, by way of example, to the accompanying drawings in which: Figure 1 is a plan view of a component of a flexible vacuum insulation panel according to the present invention; Figure 2 is cross-sectional view taken along the line A-A in Figure 1; Figure 3 is cross-sectional view showing the component of Figures 1 and 2 contained within a second envelope; Figure 4 is cross-sectional view showing the components of Figures 1, 2 and 3, forming a flexible vacuum insulation panel according to the present invention, after evacuation of the second envelope; and Figure 5 is a cross-sectional view of the flexible vacuum insulation panel according to the present invention shown in Figure 4 in a flexed configuration. - 6 -
Although the figures show the core comprising five core members of insulation material, it should be understood that the core can be produced with two or more core members.
Figures 1 and 2 show a core 1 of a flexible vacuum insulation panel according to the present invention comprising a plurality of thermal insulation core members 3 arranged substantially side-by-side and enclosed in a first envelope 5. The material of the first envelope 5 on a first major face 7 of the core 1 is interconnected by means of a plurality of lines of stitching 9 to the material of the first envelope 5 on a second major face 11 of the core 1. The lines of stitching 9 are positioned intermediate each adjacent pair of core members 3. In the region of the lines of stitching 9 the material of the first envelope 5 on the first 7 and second 11 major faces is displaced towards each other such that the material is drawn together by the stitching until ideally substantially in contact intermediate the core members 3. The regions of drawn together material sewn together by lines of stitching 9 act as hinged regions along which the core members 3 of the core 1 may be flexed relative to one another.
The core members 3 are arranged in a coplanar configuration separated by the width of a line of stitching 9.
A first method of producing a core with core members 3 is as follows. The first envelope 5 of the core is formed by two sheets of material, for example non-woven polymeric material, preferably non-woven polyester, located on top of one another being sealed together around three sides by means of heat-sealing. A single member of thermal insulation material is introduced into the first envelope and the first envelope is then sealed completely by heat sealing together the two sheets of material on the fourth side. The single member of thermal insulation material has substantially equivalent planar dimensions to the inner dimensions of the first envelope. The core is over-stitched by a sewing operation which passes a plurality of lines of stitching 9 through the first envelope 5 and the single member of thermal insulation material to cause the material of the first envelope on the first major face 7 of the core 1 to become stitched to the material of the first envelope on the second major face 11 of the core 1. The stitching, as well as attaching together the material of the first envelope on the first 7 and second 11 major faces of the core, also draws the material on the two faces together, such that the material of the first envelope on the first and second major faces of the core 1 are ideally - 8 substantially in contact in the region of the lines of stitching and the displaced material of the first envelope separates the single member of thermal insulation material into a plurality of core members 3. Adjacent core members 3 are hinged relative to one another in the region of the drawn together material of the first envelope, along the lines of stitching 9.
If the thermal insulation material introduced into the first envelope is in the form of uncompacted material, for example powders, the core may be compressed following the sealing of the first envelope, to compact the thermal insulation material prior to the sewing operation and the formation of a core with individual core members.
A second method of producing a core with core members 3 is to produce the first envelope by sealing together, by heat sealing, three sides of two sheets of material, for example non-woven polymeric material, preferably non-woven polyester, located on top of one another. A plurality of individual core members 3 are introduced into the first envelope 5 and the first envelope is then sealed completely by heat sealing together the two sheets of material on the fourth side. The core is over-stitched by a sewing operation which passes lines of stitching through the first envelope 5 in regions intermediate adjacent core members 3, causing the material of the first envelope on the first major face 7 of the core 1 to become stitched to the material of the first envelope on the second major face 11 of the core 1. The sewing operation is such that the material of the first envelope on the first and second major faces of the core 1 is displaced towards each other and the material is drawn together by the stitching until ideally substantially in contact in the region of the line of stitching. The over-stitching process produces a core with separate core members 3, with adjacent core members 3 being hinged relative to one another in the regions of the drawn together material of the first envelope, along the lines of stitching 9.
A third method of producing a core with core members 3 is to produce the first envelope by sealing together by heat sealing means, on three sides, the two sheets of material located on top of one another. The first envelope is then sewn together with a plurality of lines of stitching to produce a plurality of longitudinal compartments along the entire length of the envelope. Individual core members 3 are introduced into each of the longitudinal compartments of the first envelope. The first envelope is then sealed completely by means of heat sealing together the two sheets of material on the fourth side to form a plurality of core members 3 contained within compartments of the first - 10 envelope 5. Adjacent compartments of the first envelope are substantially separated from each other by regions of the material of the first envelope on the first and second major faces of the core which are evidently displaced towards each other when the core members are provided.
Adjacent core members 3 are hinged relative to one another in the regions of the drawn together material of the first envelope along the lines of stitching 9.
If the core member material introduced into the first envelope in the third method of producing a core is in the form of uncompacted material, for example powders, the core may be compressed following the sealing of the first envelope to compact the core members, for example in order that the core can be made more handleable.
Although hereinabove heat sealing is used to seal together the four sides of the first envelope, it should be appreciated that the four sides could also be sealed by means of sewing the two sheets together.
It should also be appreciated that although the first envelope comprises sheets of non-woven polyester, other materials may be used to produce the first envelope, for example woven polymeric material or woven glass material. - 11
It should be appreciated that where woven glass material is used, the first envelope would be sealed by sewing.
The core members 3 of thermal insulation material may comprise any of the well known materials such as powders, fibres, moulded insulation materials, pre-cast insulation shapes and compacted powders. The powders and compacted powders may comprise organic or inorganic materials and may include a microporous matrix which may also include an opacifier. The opacifier may be selected from opacifier materials comprising titanium oxide, iron titanium oxide, zirconium silicate, carbon, silicon carbide and iron oxide.
Such opacifier may be in powder, particulate or platelet form.
The compacted powders may be reinforced with fibres.
A particularly advantageous material for the core members 3 is finely divided silica having a large surface area and which can act as a getter for water and gas molecules. The finely divided silica is compacted to a density sufficient to withstand air pressure applied to a surface of a vacuum insulation panel using the silica material.
Another particularly suitable material comprises finely divided carbon particles. Such a material provides a core - 12 member structure with opacification and is also very effective when combined with silica or other materials.
The core members 3 may also be formed from fibres, which may be organic or inorganic and either natural or synthetic. A bonding agent may be used with such fibres.
Figure 3 shows the core arranged within a second envelope.
The second envelope 13 is of a form well known to the skilled person, that is the envelope is of a laminate construction with each layer fulfilling a particular purpose. A typical construction for the second envelope 13 is an outer layer of metallised polyester, for example 12 micron thick, providing an abrasion resistant surface, a second layer of metallised polypropylene, for example 18 micron thick, a third layer of metallised polyester, for example 12 micron thick, and a fourth layer of polyethylene, for example 60 micron thick, to allow heat sealing. The metallised layers inhibit permeation of water vapour and other gases, and give tear resistance. The layers are bonded to one another by an adhesive so that the laminate construction handles as a single film. The construction of the second envelope may involve more than one laminate construction such that a first laminate construction is used to produce a first major face of the - 13 second envelope and a second laminate construction is used to produce a second major face of the second envelope.
The assembly of the core members 3, first envelope 5 and second envelope 13 is evacuated and sealed using standard techniques and apparatus (not shown) known to the skilled person.
Figure 4 shows the construction of a vacuum insulation panel 15 according to the present invention after evacuation, sealing and exposure to atmospheric pressure.
Figure 5 shows how the regions of the panel 15 corresponding to the position of the lines of stitching 9 can be used as hinge lines such that flexing the panel 15 along the lines of stitching 9 enables the panel to obtain a flexed configuration.
The presence of the drawn together regions of the material of the first envelope along the lines of stitching intermediate the core members, even when contained within the evacuated second envelope, provides a degree of flexibility to the vacuum insulation panel. - 14
