Abstract
A sealed insulating panel with a first sheet or a spacer member sandwiched between two second sheets. Small spacer elements are sandwiched between the plates to maintain the spacing between the plates and provide a long conductive path. The seal is formed in such a way as to encompass the entire panel, thereby forming at least one vacuum-tight chamber. Each chamber is under partial vacuum so that external pressure pushes the plates together to form a tight fitting arrangement. The spacers on the first central sheet are staggered to maximize the length of the conduction path and thereby reduce heat and sound conduction.
Description
The present invention relates to a kind of evacuated insulation panel, more particularly, relate to a kind of glass window device.
As everyone knows, Dewar bottle is one of the most effective insulation system, and it utilizes sealed at both ends coaxial sleeve to form a vacuum chamber.The form of partial vacuum has been eliminated heat transfer conduction and convection current basically, and radioactive conduction of heat has then greatly been reduced on the low-E surface on the inner sleeve.
Do many work and attempted the principle of above-mentioned Dewar bottle is applied to include the plane insulation system of window, wall member and solar collector.This relates to the plate that uses two must divide at a certain distance.The periphery of this two boards sheet then need seal and be evacuated.The successful technology that can support at present application in this technology provides the coating of low-E and long-term sealing.But, also do not find the effective ways that can when keeping insulation effect, keep described plate spacing.
The conventional method of keeping spacing between described plate is to use pillar, spheroid or honey comb structure, or most recently used aeroge and glass fiber.These supporters or too high conductibility is arranged and too thick, or optical characteristics that can the infringement glass window with regard to glass window.
Two plates that separated by separator are all used in all suggestions of known relevant evacuated panel.Said separator must be separated installation relatively firm and usually, so that supporting atmosphere outside pressure.Therefore, these separators provide a significant conduction path, and insulation effect is reduced.
Composite board glass window device has illustrated in " the double window device of sealing factory building " literary composition that Suo Weixun (Sovalson) and Weir inferior (Wilson) are write, and this literary composition was published in " Canada's building digest " in October, 1963 that building research portion of Canadian National Research Council publishes number.
Illustrated structure is a kind of typical insulating glass unit in the above-mentioned article, this kind device has two blocks of plates that separate with the hollow metal separator, said separator then includes desiccant, and this desiccant is then surrounded by one or two sealant between frame and plate.A defective of this class formation is that the air in the folded space of above-mentioned plate very easily conducts heat and sound.Another defective is that plate can be done rapid convex-concave motion, that is to say, plate can be about crooked along with the change of air pressure and temperature.Owing to reflect and distortion, will damage the aesthetic characteristic of this seal.And this also is harmful to for sealing, and described device is damaged.
Another problem of using the metal separator is to produce in the marginal portion to conduct heat, thereby causes the contraction and the thermal stress of interior periphery, and they also easily cause described device damaged.Remove this, the comparatively expensive air pressure inside that also can influence described device of desiccant.Under low-temperature condition, desiccant can be from air absorbed nitrogen, cause the turning-in of this glass plate.Under the condition of high temperature, then opposite phenomenon can take place.
In order to address these problems, once adopted a kind of glazing structure of extremely high price, it has very exquisite seal, in glass edge being included in movable form.
Above-mentioned all structures have almost been represented all in the world insulating glass unit products.
For this reason, one of purpose of the present invention provides a kind of insulating slab that has improved.
According to the present invention, it provides:
One isolated part;
A pair of continuous external sheet, and place between these two external sheet with above-mentioned isolated part;
Two groups of isolated components, one group between described isolated part and external sheet, another group is then between described isolated part and another piece plate, thereby make described external sheet and described isolated part keep at interval, simultaneously, wherein one group of isolated component is staggered with respect to another group isolated component;
Sealing device between described two external sheet, this device is lived these two external sheet vacuum seals, thereby limits a chamber that is in the described insulating slab device; And
The partial vacuum that in above-mentioned chamber, forms, at this, these isolated components and isolated part are just supporting described external sheet, and atmospheric pressure is lived in opposing.
Above-mentioned isolated part has two functions, promptly shifts the load between the staggered isolated component, and increases thermal impedance, just reduces the conductivity between second plate.Like this, isolated part can be discontinuous, and homogeneous thickness needn't be arranged.The plate that isolated part is preferably continuous, isolated component be monolithic molding with it then.
Can provide aforementioned sealing device with any suitable material, for example use epoxy adhesive, it can form both airtight also fluid-tight sealing device.Like this, said sealing device preferably bonds on the end face of this insulating slab around the periphery of described insulating slab.When being that above-mentioned sealing device needn't contact with this plate, thereby limits two independent cavity under the continuous situation as the plate of transfer load.Described sealing device can form by similar to the second plate material sheet composition in bonding or the fusion or identical materials.
One center isolated part is set then can provides another advantage, can make spacing of cut between two external sheet to Min..Different with existing technology, a long conduction path can keep small cross section, that is to say, even above-mentioned two external sheet have only very narrow interval, also can provide higher thermal resistivity.This is because the cause that the major part of any conduction path all can make it distribute along isolated part.Like this, the interval between described isolated part and each plate can be much smaller than the thickness of each plate.This has reduced when described cavity volume reduces because of pushing the danger that produces accidentally with regard to further.
The present invention also provides a kind of valve jacket, and it comprises that a kind of platy structure gets shape for can limit chamber first category vessel or a kind of tubular structure.
The present invention also provides the method for the described insulating slab of a kind of assembly.
The present invention generally had been described above already,, the present invention had been done more detailed description hereinafter with reference to the accompanying drawing of having described most preferred embodiment of the present invention.In the accompanying drawings:

Most preferred embodiment of the present invention is described in detail in detail below.
Accompanying drawing shows understands an a kind of glass window device and an opaque plate.At first, with the device of key diagram 1 to Fig. 4.
This kind glass window device has a center glass plate A, and this plate provides an isolated part, and a side of these parts engages with subplate B, and opposite side then engages with the subplate C that same configuration is arranged.
Be installed in respectively between every couple of plate A and B, A and the C with thin smooth isolation disc 21, they separated in parallel to each other, thereby provide in skim space 23 between plate A and the B and the similar spaces between plate A and C 25.The seal closure D of assembly periphery is stated in topped residence
1Gas tight seal around assembly plate groups A, B, C periphery is provided, thereby has made space 23 and 25 become vacuum sealing chamber.Provide nonvolatil partial vacuum also promptly for chamber 23 and 25.
The best approach of producing said apparatus is as follows.Make plate A water intaking mean place, disc 21 suitably is placed on the surface of this plate, plate B then overlays on the described disc.After this, laying disc on the plate B again and plate C is being overlayed on this disc, thereby constituting an assembly by stacked plate A, B, C and therebetween disc.
Vacuum sealing device D can make with any suitable material such as epobond epoxyn.As shown in Figure 4, in order to reduce the volume of this sealing device, make the sealing device be arranged at plate B, C between the peritropous surface, rather than be bonded on the central plate A, thereby formed two independent cavity.
To isolate disc by plate A, B, the formed assembly of C is clipped in their centres and isolates closed chamber 23 and 25.
Show among Fig. 5 and Fig. 6 and understand another kind of structure of the present invention.Wherein seal closure is a kind of continuous in cement or the suitable thin layer D that constitutes of material
1, this thin layer extends around the periphery of described device.In order to be coated with thin layer D
1, to plate very thin copper film 29 at the edge of glass plate earlier.In order to vacuumize, adopted a socket 31 that passes the sealant device.
As shown in Figure 3, plate A can give brachymemma so that chamber 23,25 fuses, thereby no longer needs to vacuumize respectively.In Fig. 6, can be evacuated by socket 31, then it is nipped off and seals.
Assembly
The character that constitutes described each optimal components of glass window device is as follows.
Glass
The character of glass is unimportant.Any suitable glass be can use, stained glass and/or coated glass comprised.But structure of the present invention is particularly suitable for using from about 2mm to about 6mm, is preferably the thick thin glass of 4mm.Optimally then be to use glass tempering or that heat strengthens.Because the glass of low-E can produce high insulation values, thereby it has special advantage.But in that not have method to eliminate a large amount of when hot, this kind glass should not be used as central plate A.
Separator
The most handy thin transparent plastic material of separator such as vinyl or polycarbonate etc. are made.Optimal material then is plasticised polyvinyl chloride and the polycarbonate that contains ultraviolet inhibitor.What separator was ideal is that diameter is the disc of 1.5mm to 6.5mm.This disc can be stamped out by the flat plate of above-mentioned material, and is pure transparent.This kind separator preferably possesses the original depth of the 0.5mm to 1mm that has an appointment, so that correspondingly set the spacing between all plates, that is to say, this spacing is less than the thickness of every plate basically.
Preferably the separate each other center to center distance of about 12mm to 75mm of described separator, the center to center distance of 50mm then is best.This center to center distance partly is by the anti-pressure ability of separator and causes the atmospheric pressure of glass bending to be limited that glass bending then can cause macroscopic distortion and touch and close.Described separator is staggered to the conduction path that can significantly increase by described insulating slab.
Effectively conduction path will arrive next nearest isolated component via an isolated component by the slender space of first plate.
Described isolated component can be bonded on the glass surface, but also can not be bonded on the glass surface, is not having under the bonding situation, and separator can only be remained on and should be had on the position by atmospheric pressure.In this case, if vacuum failure, the separator that is in the glass device of vertical placement will play the warning effect, drops to the bottom of this device.
Separator is preferably nonrigid, and can be in 2% to 20% scope compress slightly between described plate.
The elasticity of separator material can make isolated component play following all effects, that is:
ⅰ) slow down and/or reflect vibration (thereby having suppressed the propagation of sound) via insulating slab;
ⅱ) can adapt to motion between plate, this motion is caused by vibration, airflow loads or variations in temperature;
ⅲ) can imitate shape during pressurized, improve optical property therefrom with glass surface.
The glass window device
The optimum range of the permanent partial vacuum in the chamber 23 and 25 is about 10
-3To 10
-12Torr (Torr), preferably 10
-4Torr.Can partly fill air other gas in addition in the chamber 23 and 25.
Glass window device of the present invention has the structural strength that exceeds general glass window device, allows the equal fit on glass in most surfaces district.When this structure was in pressured state, the intensity that is improved was provided by layered structure, and in this structure, pressure is distributed on all plates.For example, rely on the special separator among the present invention, the airflow loads on the glass window device of the present invention can be shared by all plates.
Above-mentioned glass window element will have very high hot transfer impedance.Because low diathermaneity is combined with vacuum, thereby three kinds of common interchange of heat forms such as conduction, convection current and radiation all can be eliminated effectively, or significantly reduce at least.
Comprise that as Fig. 7 30 are shown with in the insulating slab of curved edge, all can use isolated component in a manner described having different shape.
Fig. 8 shows clear a kind of insulating slab 32, and this strip has one first plate 33, a pair of second plate 34a, 34b and one the 3rd plate 36 in inside.Between first plate 33 and the second plate 34a, 34b, be provided with two groups of isolated components shown in 38,40.Between the second plate 34b and the 3rd plate 36, also be provided with one group of additional isolation element, shown in 42.
Each isolated component in the isolated component group 38 is staggered with respect to isolated component adjacent with it in the isolated component group 40, equally, each isolated component in the isolated component group 40 also is staggered with respect to isolated component adjacent with it in the isolated component group 42. Isolated component group 38,42 can be corresponding.
Fig. 9 shows clear a kind of insulating slab 50, and this plate is except that its plate is crooked, and remainder is all the same with insulating slab 40.
All previous constructions all are applicable to the transparent glass window device made by glass sheet or make the formed insulating slab of opaque plate by other material such as metal.Following embodiment has comprised and has had integrally formed ripple, protruding isostructural plate or insulating slab.Like this, although in some applications, but the plate shown in glass or other transparent material be processed into or the shape of insulating slab, but also can use other opaque material.
Figure 10 shows clear another kind of insulating slab 60, and this strip has first plate 62 and a pair of second plate 64 as isolated part.In this case, staggered isolated component is integrally formed with above-mentioned first plate 62.Can form staggered isolated component by the mode that makes thin plate produce ripple, so that form staggered ripple 62a and 62b.
Figure 11 shows clear another kind of again insulating slab 70, and this strip has one first plate 72 and a pair of second plate 74.In this case, staggered isolated component is the structure that staggers mutually on the opposed surface of first plate 72.
Figure 10 and isolated component shown in Figure 11 are hemispheric, thereby a kind of some contact is provided, to reduce the coefficient of conductivity by described isolated component.Certainly, the contact of this point also can be provided by other shape shown in Figure 12, in Figure 12, number indicates each respective plates with the reference number of Figure 11.For example, isolated component can be formed on second plate 74 shown in Figure 12 a and be tapered 75, and it is done to put with first plate 72 and contacts.Figure 12 b and Figure 12 c then show the bright situation of using sphere 76 and cylindricality 77 isolated components.
Can be independent of plate provides separator, perhaps provides separator with plate with being integral.For separator independently, they can link up by meticulous grid.So that big relatively plate is done fast and accurate localization.This technology has than big thickness and for being the most suitable under the opaque situation at plate, for example can be used for improving the intensity of plate.In addition, described grid also can be processed into to have much smaller than plate thickness at interval, so that prevent or reduce at least and the contacting of plate.The edge of second plate 74 can be crooked so that make it near plate 72, thereby make the edge weather strip have minimum possible width, so that keep partial vacuum.
Further specify below, when a plurality of chambers link together (Fig. 3), it is continuous that center panel 72 can need not to be.An effect that function has been an isolated part of center panel, so as between two groups of separators transfer charge.Thereby, can between each separator, provide space or through hole with mold pressing or when otherwise forming described separator and center panel 72.
In order to help separator and to locate, can be provided with coupled that engages with separator with this separator mold pressing all-in-one-piece plate.Like this, described separator just can comprise and be formed on two relatively auxilliary mutually isolated parts on plate, makes the merging of joining of this two boards sheet and described separator that described plate is suitably located.
The insulating slab of solar collector 80 forms is got in Figure 13 explanation, and this strip has one first plate 82 and second plate 84 and 85.As previous embodiments, between first plate and second plate, dispose two groups of staggered isolated components, promptly among the figure shown in 86 and 88.Have one apart from the insulation plate 90 of second plate 85 certain intervals forming a hot trap 92, this trap generally includes a conduit that is used for the heat absorption fluid.According to the present invention, plate 90 also can insulate.First and second plate 82,84 is transparent, can directly radiant heat be sent to hot trap 92.On second plate 85, be provided with the coating 93 of low-E, in order to prevent that the radiation heat loss is to the outside.85 of second plates can be made by any suitable opaque material, enter the radiations heat energy of this gatherer and the heat that is absorbed is conducted to hot trap 92 with absorption.
With reference to Figure 14 a and Figure 14 b, the valve jacket among the figure shown in 100 has two insulation plates 102, and this kind plate comprises a base plate 104, and this base plate then is by nested two cube members 106 and 108 and integrally formed.These two insulation plates have common outer rim 112.Each cube member is in fact all formed by five limit chambers.The independent plate of chamber 106,108 is a spacer assembly, and this device is got the form of isolated part or plate 110, and plate 110 then has two groups of staggered isolated component 110a, 110b on its two opposite flanks; In addition, if plate 110 is also not necessarily continuous.In this case, isolated component can become one with the isolation plate, as shown in figure 11.As previously mentioned, also be formed with border seal at peripheral 112 places.
The distinguishing feature of case chamber 100 is: do not have excessive edge penalty in the edge without sealing, and can form the single vacuum chamber of being convenient to produce.As hereinbefore, remain in contact with one another, thereby respectively isolate plate and needn't engage in its lower edge because environment stress makes these isolate plates.
Any structure that the limit arranged all can be by assembling up such as pentagon or analogous shape, taper, hemispheric mode.In addition, such sheath body also can not built base plate, promptly in a tubular form, in this case, then will on insulation top of plate and lower periphery border seal be set.For more complicated shape, then need to use the polylith plate, but still many plates are linked together, and form for example inner space of an entity, and except all not providing and extraneous direct, conductive leading at its each place, aperture.
Although isolated component is said to be by transparent elastic material hereinbefore and makes, they also can effectively be stood external pressure and have not the suitable material of deflation characteristic basically to make by any other.They only are only transparent in the place of necessity.
Can resist external pressure, the airtight and any suitable material that has air tight characteristic basically in order to keep the partial vacuum in the insulating slab, can to use to have.
Although the present invention be with device with three, four plates for for example with explanation, the quantity of plate also can be five or more, and inner plate also can be discontinuous.
In the application's device, between all plates, there is displacement hardly, and also has stress hardly at bonding interface.
When environment stress or temperature changed, general insulating slab can exhaust when through hole is arranged with outside the connection, perhaps can bend when sealing.The exhaust meeting causes the moisture that causes the insulating properties reduction and produce fault and holds back; And bending also can reduce insulation values, and weakens the intensity of plate and make its profile generation deformation.Perimeter seal in the general insulating slab plays a part structural element.On the other hand, in insulating slab of the present invention, described periphery sealing then is mainly used to keep partial vacuum.
General insulating slab depends on air collected, that be used as insulation, thereby its insulation values increases along with collected air capacity.Increase air capacity, will make the plate thickening.This will gain in weight and cost in increased capacity or degree of crook.On the other hand, only need between the plate of insulating slab 10, have enough gaps to prevent that them from contacting here.The laminated piece of Xing Chenging is a kind of thin, economic and firm insulating slab like this.
Even in order to change insulating properties, should on chamber, connect an air pump 120 and valve 122, as shown in Figure 6, thereby air or other suitable gas can be passed in and out as required in order to cause significant conductibility.For the gas beyond the air, the air pump 120 also suitable gas container of Ying Yuyi links to each other.
In order to obtain high vacuum, can dry and the degasification operation, so that control remaining gas, steam or the like.
