The single feature that provides in specific embodiment and/or illustrate is not limited to this embodiment or is not limited to other the combination of features with this embodiment, and in the framework of technical scheme, with the variation scheme combination of all other, even it does not relate to especially at this manual.

Identical Reference numeral in each diagrammatic sketch of each figure and accompanying drawing is represented same or similar ingredient or is played the ingredient of identical or similar effect.The do not have Reference numeral feature such according to diagrammatic sketch in the accompanying drawings also is clearly, and this is with whether to have described or do not described such feature irrelevant.That comprise in this manual on the other hand but can not see in the accompanying drawings or unshowned feature can be understood without difficulty for those skilled in the art.

In Fig. 1, schematically illustrate the phantom drawing of fabrication stage 2, so that the shape and the structure of explanation chamber 3 and its wall 4 or partition wall by the embodiment of evacuated insulation panel 1.Fig. 2 illustrates the schematic diagram of the structure of evacuated insulation panel 1 with lateral view or vertical sectional plane.More clearly obtain explaining at the embodiment of the manufacture method that is used for evacuated insulation panel process and separately manufacturing step relatively with Fig. 3-8 after the evacuated insulation panel 1.

Evacuated insulation panel 1 is made of chamber core 5, and it is imitated in the present embodiment and does honeycomb, and therefore is also referred to as honeycomb core.It adopts hexagonal shape, and wherein octagon and other shape comprise that irregular shape also is possible.Chamber core 5 constitutes by wall 4, thereby and comprises chamber 3.This structure and structure are very stable, only need less material and are very light.

In order to constitute the corresponding plate 7 of chamber 3 compacting that is shaped as half chamber 6, and bonded to each other in order to constitute complete chamber 3 subsequently (as shown in the diagrammatic sketch of Fig. 3-6 like that) or weld.Form the individual system of sealing like this.The plate of manufacturing also can be described as half chamber panel 7, and to stack up and down in the structure shown in Fig. 1, and for securely with airtight be connected for example bonding at their contact position place 8, wherein preferably before Next plate 7 is placed and is bonding etc., always on a formed composite members 9, place a new plate 7, carry out bonding then.Transverse to chamber opening or honeycomb opening such piece of 10 cuttings or composite members 9, so that the height of chamber 3 or its wall 4 provides chamber-or the height of honeycomb core, as shown by the diagrammatic sketch of Fig. 6.Just provide to illustrative intelligible size among this external Fig. 6.

By with cap rock 11 sealing be fixedly mounted on the corresponding side of chamber core 5, on both sides with each cap rock 10 locking chamber opening 10.Generate the cell or the chamber 3 of many little sealings like this, and the height of chamber 3 draws the thickness of evacuated insulation panel 1 with the thickness of cap rock 11.Preferably, two cap rocks 11 one after the other in the independent course of work with chamber core 5 bonding and second cap rock 11 bonding in about 98% vacuum particularly.Replace bonding and other fixed form also is feasible, directly be connected to each other as welding or the still unhardened or only subsclerotic material by chamber core 5 and/or cap rock 11.Preferably, the material of cap rock 11 contains still unhardened resin, in any case so that hardening of resin all under vacuum, carry out when being connected second cap rock 11 applying, thereby this vacuum automatically obtains in single chamber or honeycomb cells 4 and keeps.

Preferably, cap rock 11 is made of the epoxy resin that strengthens.Shown in the schematic flow sheet of Fig. 7 and 8 like that, each cap rock 11 wetland in each independent manufacturing step is made a shape and is hardened under vacuum.Be pressed onto in the cap rock 11 that is not coupled as yet, at this wall 4 so that when the hardening of resin of all cap rocks 11, the wall 4 of chamber 3 is connected with described cap rock 11 airtightly with chamber 3.Mode and the advantage that reaches is by this method, to a certain extent cap rock 11 on core 5 the combination manufacturing and fixedly the time, cap rock 11 is firmly and non-dismountablelyly and be connected with the wall material of core 5 airtightly.

So generate have high rigidity, the sandwich material of low weight and very little support.Have the wall 4 of chamber 3 but do not have the core 5 of cap rock 11 in special embodiment, to have bulk density and 1: 17 support and one cubic metre the ratio of about 60kg/m3.Yet this ratio for example also can be in 1: 33 the scope.So little support/space comparison insulation is favourable.

Also can use other material for cap rock 11, the derivative that constitutes of melamine resin and phenolic resins for example, this is a kind of very cheap solution.May for example be connected with the core 5 of evacuated insulation panel 1 respectively by such cap rock 11 by bonding.Also can use other plastics.Particularly cap rock 11 also can contain the reinforce 12 that is made of glass isolator, kraft or sisal etc.The particularly preferred bed thickness of cap rock 11 is about 1mm.

In another structure, cap rock 11 is in its outside, and just a side of core 5 is provided with protective film 13 dorsad, as aluminium film 14 particularly.The advantage that a kind of such protective film 13 and particularly aluminium film 14 has is; when manufacturing is connected with chamber wall 4 with cap rock 11; the special resin material of protecting the corresponding mould that carries out in the Connection Step in the end not to be included in the cap rock 11 damages, so that the bonding of not expecting of such resin material can not take place in mould.So in addition protective film or topping 13 constitute the diffusion barrier that works and prevent that air from entering in the vacuum chamber 3.Also realize other advantage just when using aluminium film 14 grades, promptly this surface of giving out light with it is used as the reflection obstruct that is used for the IR-radiation, thereby additionally improves the insulating capacity of evacuated insulation panel 1.

Conduction of heat is realizing by so-called support pipeline, gas pipeline and radiation pipeline when putting into practice known traditional insulation materials and constitute.About 2/3 gas pipeline with all hot channels has lion's share.In order to eliminate this share, the thermal insulation material in modern times is evacuated, cancel gas pipeline thus at least as much as possible.Radiation pipeline interrupts its reflected back IR-radiation by the surface of reflection.

Air also is drawn out of in evacuated insulation panel according to the present invention, thereby has cancelled gas pipeline.Use in the structure of aluminium film 14 as protective film 13 corresponding, the IR-radiation stops by the luminous surface of height.Remaining keeps the support pipeline, and it is gone out by the thermal conductivity of stock and its Mass Calculation.

The core 5 of evacuated insulation panel 1 is opened by so-called cardboard and is constituted in the current embodiment that relates to.Cardboard is opened according to used reinforcing material and is had 0.1-0.2W/mK in cubic meter.Core with chamber 2 is according to the size of the chamber 30-60kg/m that weighs ³Provide the support share in cubic meter thus, have for example about 1: 17 as already mentioned to about 1: 33 ratio, wherein it relates to preferred value.It is for example applied that to have the value that has provided be that the thermal conductivity that the cardboard of 0.1-0.2W/mK is opened causes the value of the support pipeline of evacuated insulation panel 1 for example to be 0.0058-0.0117W/mK to 0.0029-0.0058W/mK.

Against vacuum insulating slab 1, importance are that air diffusion is in the cavity that vacuumizes.Evacuated insulation panel 1 is in constant gas pressure, and it attempts to realize pressure balance between the vacuum in atmosphere and the chamber 3 at evacuated insulation panel 1.

Constitute by foam core, protective film and plastics-barrier film of being coated with aluminium mostly by the known evacuated insulation panel of practical experience.This barrier film is because its less bed thickness has only the diffusion of preventing lessly.Attempting by putting into practice known evacuated insulation panel, compensating this shortcoming by the special film of preventing.Another shortcoming of known evacuated insulation panel is that it is made of a vacuum chamber because foam core is by the foam manufacturing of opening porous, thereby and pressure balance on whole system, work simultaneously.

Have very conclusive advantage in this special structure according to evacuated insulation panel 1 of the present invention because pressure generally only externally chamber on the edge between the cap rock 11 15 3 or honeycomb place load.Because single chamber 3 is sealed to each other relatively, thus must realize pressure balance in the chamber 3 at first externally, and inwardly diffusion gradually then.This advantage also reaches by following measure, that is: the core 5 according to evacuated insulation panel 1 of the present invention is made of many single chambers 4, and air can only one after the other enter into described single chamber from the edge between cap rock 11.In order further to suppress this effect, set according to preferred structure, core 5 its free edge 15 be between the cap rock 11 with synthetic resin for example non-proliferation such as synthetic resin spatula material encapsulate hermetically.

Air pressure also works by 11 pairs of all chambers 4 of cap rock simultaneously.This according to evacuated insulation panel according to the present invention 1 according to corresponding special tectonic and protected especially; its cap rock 11 not as general common, constitute by the plastic sheeting of thin sensitivity; but constitute by the epoxy resin layer 12 of the enhancing that about 1mm is thick especially; it additionally also can be provided with aluminium film 14 as topping 13, as shown in figure 2.In addition for aluminium film 14, high-isolation film also can be or constitute the ingredient of topping 13.Replacement is as the structural type of film, and topping 13 is also realized as coating.

Below also with inquiring into some manufacturing processes or step in more detail, also provide or illustrate other device characteristic of evacuated insulation panel 1 at its periphery.

Pressboard 7 in chamber pressing station K (referring to Fig. 4), it constitutes half chamber 6 and becomes core 5 by described half chamber bonded together subsequently in cross section.The wall 4 of chamber 3 or the material of partition wall, or the material of the wall 4 of the core 5 of differently saying so or partition wall is to be made of kraft in shown embodiment, and it applies with melamine-phenolic resins-derivative.Resin sclerosis in about 6 seconds under the temperature of the pressure of 30bar and 185 ℃.The advantage of resin is that crosslinked takes place in the same long time with the input energy.So resin can be dry, and not sclerosis fully.Wall material is provided for further being processed into finished product, and differently carries out drying with other resin system and reaction is only carried out under pressure and heating, so that harden.Cross-linking process carried out in about 6 seconds fully.Ejection gas no longer takes place subsequently.Another advantage of this material is, it is cheap and no problemly can store for a long time as raw material.

The wall 4 of chamber 3 is that about 0.5mm is thick, and the size of each 10mm, and each chamber 3 provides the length of material of 49.6mm for wall 4 thus.This value should be understood to be illustrative and can change according to structure types and needs.

In order on applied forcing press P, to make essential pressure not become too high, for example in a plate 7, suppress five and half chambers 6 simultaneously.For wall material needn't extend, the preferred predeformation of described material.For example this material in the time of 60 ℃ flexibly and pressure distortion that can be less, so when starting chamber pressing station K, use heat radiator W.Also can heat operated pressing tool for heat radiator W in addition.Because predeformation can be carried out very fast and need little pressure, can use and drive simple precompression machine VP in addition with pneumatic linear actuator PZ.Obtain pre-plate 7 ' by the precompression machine, this pre-plate is made plate 7 in the subsequent compression step.An example of this procedure division schematically illustrates in Fig. 3 and 4.Whole pressing process is formed in correspondingly all heating by paper, distortion and actual compacting.

The cross section that has of manufacturing is that the plate 7 of the shape of half chamber 3 is input in the bonder of core-or piece-automatically (not shown go out) like this, and in this automatic bonder, described plate 7 is bonded into piece 16 equably, and it also can be described as honeycomb block or chamber piece.In Fig. 5, schematically illustrate, how two blocks of such plates that just illustrate partly 7 stack up and down mutually, so that be connected to each other securely and airtightly on its contact site 8 constituting under the situation of chamber 3, this can carry out by bonding or welding or in other modes that are fit to.

For example, the position that contacts with each other of stacked plate 7 or the adhesive that contact site 8 is provided with quick-hardening about in the of two, it for example applies with automatic device.In practice, adhesive is coated on the single plate 7, thereby before it contacts with each other and fast with bonding well.Repeat this step, connect securely mutually until the plate 7 of sufficient amount and constitute a piece 16.

Replace plate 7 to be bonded into a piece 16, also can be similarly make by a plurality of plates 7 for described by for example welding in a forcing press (not shown go out).

Such piece 16 (described for example have exemplary size and can see in Fig. 6) can be transported in the saw (not shown go out) then.Then from piece 16 transverse to plate 7 according to desired subsequently plate thickness, just under the thickness of the cap rock of considering also will install 11, cut out chamber dish 17.Chamber dish 17 direct cores 5 corresponding to the evacuated insulation panel of making thus 1.

In next manufacture process part, chamber dish 17 is provided with cap rock 11 and for example generates vacuum in chamber 3.As illustrating hereinbefore, can carry out with the gas material of selecting in the filling of this chamber 3.First cap rock 11 and the installation process that also has second cap rock schematically shown in Fig. 7 and 8 with about details referring to this shown process.

Place protective film 13 according to Fig. 7 in step S1 in mould F, for example the aluminium film 14.In step S2, on protective film 13, place the resin bed 12 that strengthens.In step S3, on described resin bed, place chamber dish 17 or core 5 again, use thereon and cover D closed mould F, and from the inner chamber with lid D sealing, deflate (step S4).Inner room towards mould F covers on lid D with rubber bar G loosely; thereby so that the inner room of mould F vacuumize and the air between lid D and rubber bar G flows on the free side that the rubber bar is pressed in core 5 and core is pressed on the resin bed 12 of enhancing; it also is pressed on the topping 13 simultaneously at this, as shown in the step S5.Be pressed into securely in the wet resin of cap rock 11 at this core 5.It is so long that this state keeps, until the hardening of resin of cap rock 11.In step S6, after sclerosis, allow air to flow into again in the inner room of mould F and after lid D opens and to take out the composite members that constitutes by the core 5 and first cap rock 11.

Then, as shown in FIG. 8, place protective film 13 in mould F ' in step S11, for example the aluminium film 14.In step S12, on protective film 13, place the resin bed 12 that strengthens.Place the composite members that is made of the core 5 and first cap rock 11 in step S13 on described resin bed again, (step S14) thereon deflates with lid D ' closed mould F ' and from the inner room with the mould F ' that covers D ' sealing.Lid D ' covers with rubber bar G loosely towards the inner room of mould F '; so that the vacuumizing and the air inflow between lid D ' and rubber bar G ' of the inner room of mould F '; thereby the rubber bar is pressed on the free side of the composite members that constitutes by the core 5 and first cap rock 11 and composite members is pressed on the resin bed 12 of enhancing; it also is pressed onto on the topping 13 simultaneously at this, as shown in the step S15.Be pressed securely onto in the wet resin of second cap rock 11 in this composite members that constitutes by the core 5 and first cap rock 11.This state keeps so longly, until the hardening of resin of second cap rock 11.In step S16, after sclerosis, pass air into again in the inner room of mould F ', and after lid D ' opens, can from by mould F ', take out the evacuated insulation panel of making 1.Evacuated insulation panel 1 can also be cut into Any shape afterwards.

In Fig. 9 and 10, another embodiment that is used to construct the chamber core 5 that comprises a kind of pattern schematically is shown respectively with sectional drawing or phantom drawing.In this pattern, draw the chamber 3 of semicircular chamber 3 ' and X-shape ", thus realize a favourable combination, be used for carrying out less conduction of heat by the wall between cap rock 11 4.For the view in Fig. 9 and 10,,, cut into dish (surface that the view of Figure 10, just in time is parallel to accompanying drawing) from the block fabrication stage as in the embodiment of above-mentioned manufacture method in order to make the chamber core 5 that is used for evacuated insulation panel 1.

About the shape of the pattern of chamber, it is possible also having other modification.So mutually identical hemisphere (not shown go out) can be arranged in the plane by equidirectional on the one hand.The second layer again reciprocally and the hemisphere identical with the hemisphere of first floor be provided with so thereon, make a hemisphere of each hemisphere of first floor and the second place at what a some place just contacts.On the open side of hemisphere, cap rock is installed.Conduction of heat must and be merely able to be undertaken by the contact point of hemisphere then, this means quite few material.This mode is not limited to hemisphere, but works with the shape of any dome-shaped, and its less thickness according to evacuated insulation panel 1 can correspondingly be flat also, as the parts of spherical part or spherical or the shape of other dome-shaped.Such pattern for example can be made in for example single first floor and the second layer, and make the core of finished product in some processes by die casting, deep-draw and other known technology not only in the fabrication stage.

Material about core 5 materials is right, and all combinations all are favourable, consequently optimizes as far as possible little conduction of heat.It is right that this is not the known material that is made of paper and melamine/phenolic resins-derivative.If this organic material paper and timber inorganic material replace as glass fiber material, have so just reduced conduction of heat.For the material of core 5, pure ceramic base material can consider that also the combination of multiple material neither be compulsory in addition.

The present invention just illustrates to illustrative in the accompanying drawings and is not limited to this in manual neutralization by embodiment, but comprise all modification, improvement, replacement and combination, those skilled in the art can be from patent document, especially in the scope of claim and all accompanying drawing in the introduction at this manual and the description of embodiment draw the present invention, and can with those skilled in the art's professional knowledge and prior art combination.All single features of the present invention especially and structure possibility and its embodiment are capable of being combined.
