The present invention relates to utensils such as deep freezer, vacuum bottle, incubation canteen thermally insulated container that uses and the manufacture method that is used for the thermal insulating material and the thermally insulated container thereof of these thermally insulated containers, and at length be presented in the airbag of airtight interlayer of the interlayer container that is combined into one by endogenous pyrogen and outer container, enclose the gas that thermal conductivity is lower than air.Therefore the present invention relates to the thermally insulated container made as thermal insulating material and the manufacture method of used thermal insulating material and this thermally insulated container.
In the past, thermally insulated containers such as above-mentioned deep freezer, its endogenous pyrogen and outer container are made by synthetic resin, organic foam materials such as filling hard polyurethane foam, polystyrene foam in the interlayer between interior outer container, perhaps fill inorganic material such as perlite rock, as the adiabatic layer of thermally insulated container.
And endogenous pyrogen and the outer container made with metallic material form vacuum heat-insulating layer between the interlayer of container and outer container within it and make thermally insulated container.
But, use expanded material to make the thermally insulated container that heat guard is filled, because the permeability to heat of thermal insulating material is big,, need to increase the thickness of adiabatic layer in order to improve the heat-insulating property of thermally insulated container.Moreover during filling foaming body, in order to improve the efficient of filling procedure, adiabatic layer must have certain thickness between the interlayer of interior outer container, and the result is, the 5-10 that the thickness of thermally insulated container packed layer is about the vacuum insulation layer thickness doubly.Thus, the thermally insulated container of filling thermal insulating material, its Volumetric efficiency is that thermally insulated container diminishes in the ratio of the effective volume of closing endogenous pyrogen under the state of lid to total volume, therefore can not satisfy the requirement that portably uses fully.
For the thermally insulated container that vacuum heat-insulating layer is arranged, though the very thin thickness of adiabatic layer, heat-insulating property is good, the use that is easy to carry, but manufacture method complexity, cost height.In addition, in order to increase endogenous pyrogen and the outer container ability to bear to bar pressure, endogenous pyrogen and outer container are wanted to bear bar pressure and the shape of having placed restrictions on container, and the technology of using the square container of easily making is difficulty just.
The object of the present invention is to provide a kind of cheap, heat-insulating property is good, Volumetric efficiency is high thermally insulated container and be suitable for the thermal insulating material of this thermally insulated container and the manufacture method of this insulation volume.
First style of the present invention is the thermally insulated container that forms adiabatic layer in the interlayer of the interlayer container that is integrated by inside and outside groups of containers, encloses the thermally insulated container that at least a low heat conductivity gas is made as thermal insulating material among xenon, krypton, the argon in the airbag of the interlayer between interior outer container.
In being suitable for the concrete style of this thermally insulated container, can select one of following material to make airbag, the i.e. film of synthetic resin of film of synthetic resin, sheet metal cover and metal vacuum coating film of synthetic resin etc.The thickness of thermal insulating material with below the 5mm for well.In this interlayer can be with a plurality of thickness thermal insulating material below the 5mm stacked form better.The foamed thermal insulating with softness is preferably filled between the interior outer container of interlayer container and the space between thermal insulating material.
Second style of the present invention is in the airbag that is made of the gas tightness film, encloses a kind of low heat conductivity gas in xenon, krypton, the argon at least with as thermal insulating material.
In being suitable for the enforcement style of this thermal insulating material, can select one of following material to make airbag, these materials comprise the film of synthetic resin of synthetic resin, film, sheet metal cover and metal vacuum coating film of synthetic resin etc., for preventing gaseous exchange, the inside face of airbag is preferably made corrugated.Stacked by many airbags, and in each airbag, enclose the gas of low heat conductivity.Every layer thickness is less than the such thermal insulating material the best of 5mm.Moreover preparation has the double walled airbag of sandwich structure, should be from structure the best of filled soft foamed thermal insulating between sandwich structure and the airbag.
The 3rd kind of style of the present invention is that endogenous pyrogen engages with outer container and is the interlayer container of the one manufacture method as a kind of like this thermally insulated container of the adiabatic layer between interior outer container, under the state of airbag on the assembled in advance in the interlayer between endogenous pyrogen and outer container, endogenous pyrogen and outer container are combined into one, then, in above-mentioned airbag, fill at least a low heat conductivity gas in xenon, krypton, the argon, then this airbag is sealed to make adiabatic layer.
In being suitable for the enforcement style of this method, airbag is made of one of following material, and these materials comprise film of synthetic resin, the thin mould of sheet metal cover synthetic resin and metal vacuum coating film of synthetic resin etc.The thickness of adiabatic layer with less than 5mm for well.The a plurality of airbags of stacked arrangement in the interlayer between endogenous pyrogen and outer container seal a plurality of airbags of low heat conductivity gas respectively with these, stacked assembling the best.
In being more suitable for the concrete style of this method, airbag is provided with the tubular gas introducing port, and on the interlayer container, be provided with the outlet of this gas introduction port, when between interlayer during the assembling airbag at the interior outer container of interlayer container, to this gas introduction port be extracted from the opening part of interlayer container, from gas introduction port filling low heat conductivity gas in the interlayer container that disposes airbag, then gas introduction port is sealed, the pipe of sealing gas introduction port is packed in the opening, preferably again this opening (outlet) is clogged.
Thermally insulated container of the present invention, because in the interlayer of endogenous pyrogen and outer container, wherein enclose and dispose the airbag of at least a low heat conductivity gas in xenon, krypton, the argon as thermal insulating material, compare with the thermally insulated container that former use foaming body is made thermal insulating material, its adiabatic layer attenuation, so the Volumetric efficiency of thermally insulated container has had raising.That is to say with the thermally insulated container that uses foaming body etc. to make thermal insulating material and compare that have under the situation of equal heat-insulating property, the thickness of adiabatic layer can reduce by more than 50, and therefore can increase its effective internal volume.In addition, make the thermally insulated container of thermal insulating material with polyurethane foam, because the poor heat resistance of polyurethane itself, even endogenous pyrogen and outer container use the good synthetic resin of resistance to effect of heat, can not be used as the uses such as vacuum bottle that can add hot soup, yet thermally insulated container of the present invention, its endogenous pyrogen and outer container and airbag all are to make of resistance to effect of heat good synthetic resin or metal, therefore can be used as cool-bag.In addition owing to use the thermal insulating material of filling gas, thereby make the thermally insulated container lightweight as airbag.
In addition, compare with the thermally insulated container of band vacuum heat-insulating layer, its endogenous pyrogen and outer container additionally do not bear the barometric pressure load, thermally insulated container must not made withstand voltage shape, therefore thermally insulated container energy attenuation, and make its whole lightweight, and can be made into the casing of the different shapes such as rectangle on plane.
Also have, owing to all be filled with the thermal insulating material of flexibility between interior outer container, reaching between outer container and airbag, the heat-insulating property that makes the rotation angle position that the thickness of airbag can attenuation is also because of using these thermal insulating materials to be compensated, thereby can improve the heat-insulating property of thermally insulated container.
If adopt the manufacturing process of thermally insulated container of the present invention, in the interlayer of endogenous pyrogen and outer container under the state of assembled in advance airbag, endogenous pyrogen and outer container are combined into one, also seal it subsequently toward the interior filling low heat conductivity gas of airbag then, make airbag under contraction state, it be packed in the interlayer into airbag even so very narrow and small interlayer also can be packed into.Compare with filling foaming body operation or vacuum seal operation, toward the interior filling gas of airbag, only seal operation can be made thermally insulated container simply, therefore can improve the manufacturing efficient of adiabatic objective device, and then make simple to operateization of making thermally insulated container, again because of not needing foaming body and vacuum, thereby reduced the manufacturing cost of thermally insulated container again.

Endogenous pyrogen 2 and outer container 3 can be used following material, and these materials comprise: synthetic resin materials such as ABS resin, polypropylene, polyethylene, poly terephthalic acid diethylester, polycarbonate, polystyrene, acrylic resin, hard PVC.The material of container 2,3 also is not limited to synthetic resin, with stainless steel and other metal materials make also fine, or one with synthetic resin another is made of metal and also can.
Opening is made on the top of endogenous pyrogen 2, be formed with the case shape at the end, make flange 2a in the top.Outer container 3 is made square tube shape, be connected to base plate 3b in its sidewall 3a lower end.Sidewall 3a is assemblied in endogenous pyrogen 2 outsides, and the bottom on the flange 2a top of the upper end of sidewall 3a and endogenous pyrogen 2 connects and is one.Methods such as engaging and the lower end of sidewall 3a and engaging of base plate 3b of the bottom, top of the upper end of sidewall 3a and the flange 2a of endogenous pyrogen 2, joint method can select for use lining cement to engage, heating is merged, the sound wave that becomes is fused.Base plate 3b centre at outer container 3 has a round mouth 3c, is preferably made or to cover the osed top structure with shrouding.
Preferably set up at the inside face of the outside face of endogenous pyrogen 2 and outer container 3 and to have prevented thermal-radiating metallic membrane, metallic membrane can be selected the vacuum evaporating method for use, and one of methods such as chemical method or electrochemical plating or its two kinds of methods combine metal or alloy plated films such as copper, silver, aluminium, chromium are formed.
The airbag 5 that inserts in the interlayer 4 between endogenous pyrogen 2 and outer container 3, shown in the expansion drawing of Fig. 3, its structure comprises the side 5a that links up around rectangular bottom 5b and the 5b.Central part below the 5b of bottom is opened a tubular gas introducing port 5c who extends out.Airbag 5 can select for use synthetic resin thin slice of film of synthetic resin, sheet metal cover synthetic resin film or metal spraying etc. to make.The material of synthetic resin thin slice with its gas release amount and the penetrating amount of gas is little and material that rigidity is high for well, for example polypropylene, poly terephthalic acid diethylester, polyester, polycarbonate, polystyrene, hard PVC, polyamide etc.The thickness of film of synthetic resin is preferably 0.05~1.0mm.The metal cover film is to be formed by stacking with metallic papers such as aluminium foil and above-mentioned film of synthetic resin, and the film of synthetic resin of metal spraying is then made metal vacuum spraying platings such as aluminium to above-mentioned film of synthetic resin.
Low thermal conductivity gas a kind of or that its miscellaneous gas is formed in the inert gas argon that above-mentioned permeability to heat is low, xenon, the krypton is introduced airbag 5 by gas introduction port 5c, and seal it subsequently, again 4 side 5a are erected, place the interlayer between endogenous pyrogen 2 and the outer container 3, be made for large-sized under casing shape that has.
In the interlayer of endogenous pyrogen 2 and outer container 3, be filled with the foamed thermal insulating 7 of flexibility in the corner that interior envelope has the airbag of gas not to be connected to, as flexible polyurethane foam etc.
About the manufacture method of thermally insulated container 1, lift an example now, be described in Figure it.
Make endogenous pyrogen 2 and outer container 3 respectively with synthetic resin, and be ready to airbag 5.In advance the end of airbag 5 is fixed on below the flange of endogenous pyrogen 2.The upper end of the following and outer container 3 sidewall paneling 3a on the flange 2a top of endogenous pyrogen 2 is engaged with lining cement (as epoxy adhesive), and the corner of the interlayer 4 between endogenous pyrogen 2 and outer container 3 fills up with foam-thermal insulation then.As shown in Figure 4, in the interlayer 4 of the outer container 3 of endogenous pyrogen 2, pack into the airbag 5 of unaerated, with lining cement (as epoxy resin adhesive) base plate 3b is bonded on the sidewall paneling 3a lower end of outer container 3, at this moment the gas introduction port 5c of airbag 5 stretches from the opening 3c of base plate 3b.The low thermal conductivity gas that one of argon, xenon, krypton or its miscellaneous gas are formed is filled in the airbag 5 from the gas introduction port 5c of airbag 5 then, thereupon with sealing or viscose glue seals gas introduction port 5c and joins.The gas introduction port 5c of good seal puts in the opening 3c of base plate 3, and with shrouding or lid opening 3c is clogged.
If adopt such thermally insulated container 1, interlayer at endogenous pyrogen 2 and outer container 3 is equipped with airbag 5 (thermal insulating material) for 4 li, wherein since in fill the little gas of thermal conductivity ratio air, compare adiabatic layer 8 attenuation with the thermally insulated container that uses foaming body, therefore the Volumetric efficiency of thermally insulated container 1 has improved, in other words, compare, have under the situation of identical heat-insulating property with the thermally insulated container that uses thermal insulating material such as foaming body, the thickness of adiabatic layer 8 can reduce below half, and effectively internal volume has increased.In addition, use polyurethane foam to make the thermally insulated container 1 of thermal insulating material, because the poor heat resistance of polyurethane self even endogenous pyrogen 2 uses the good synthetic resin material of resistance to effect of heat with outer container 3, can not be used it as the vacuum bottle that can pour hot soup into.And the thermally insulated container 1 in the present embodiment, its endogenous pyrogen 2, outer container 3 and airbag all are to make with the good synthetic resin of resistance to effect of heat, therefore be used as vacuum bottle to it so long and use.Therefore other made the thermally insulated container lightweight owing to fillings in the airbag 5 that is used as thermal insulating material is gas.
Moreover, compare with the thermally insulated container of band vacuum heat-insulating layer, do not increase the barometric pressure load of endogenous pyrogen 2 and outer container 3, also thermally insulated container 1 need not be manufactured pressure-resistance structure, this not only makes thermally insulated container attenuation and lightweight, also can manufacture the thermally insulated container of the different shapes such as rectangle box-shaped body of band surface plate.
Also have since between interior outer container and and airbag 5 between, be filled with the thermal insulating material 7 of flexibility, its heat-insulating property of place of airbag 5 became unevens is filled out thermal insulating material 7 and is compensated with adding around the corner, thereby has improved the heat-insulating property of thermally insulated container 1.
If manufacture method according to present embodiment thermally insulated container 1, assembled in advance has under the situation of airbag 5 in the interlayer 4 of endogenous pyrogen 2 and outer container 3, endogenous pyrogen 2 engaged with outer container 3 be one, filling and enclose the gas of low heat conductivity in airbag 5 then, airbag 5 is packed under contraction state in the interlayer 4, also airbag 5 can be laid into even interlayer is narrow and small like this.Compare with filling foaming body and vacuum seal operation, toward airbag 5 interior filling gass, simple to operate, easily thermally insulated container 1 is made in sealing thus, and it is made efficient and may improve.Because the manufacturing process of thermally insulated container 1 is simple, do not need foaming body and vacuum again, so the manufacturing cost of thermally insulated container 1 can reduce.
The thermally insulated container 1 of this embodiment, in the interlayer 4 between container 2 and the outer container 3 airbag 5 is housed within it, preferably airbag 5 is made the multilayer laminated structure, owing to use a plurality of airbags 5 with this stepped construction, the convection current and the thermal radiation of gas can be contained in the airbag, have improved the heat-insulating property of airbag thus.When assembling a plurality of airbag, the independent gas introduction port 5c of gas from each airbag 5 can be imported.For stoping gaseous exchange, the thickness of each layer airbag is preferably disposed on below the 5mm simultaneously.In addition, take place for preventing a bag interior convection current, airbag 5 inside faces can adopt undulatory thermal insulating material.The 2nd embodiment
Fig. 5 is an example of thermal insulating material of the present invention, and symbol 11 is heat baffles.
Heat baffle 11 is by the inwall that sandwich structure is arranged 12 with the synthetic resin manufacturing, inserts the airbag made from the air-tight membrane 13, and injects little three parts such as gas 14 1 class thermal insulating materials 15 of thermal conductivity ratio air and form in airbag.Filled polyurethane foams 16 in the gap between the thermal insulating material 15 in the heat baffle 11 and the inside face of sandwich structural body 12.The inside face of the airbag 13 of thermal insulating material 15 is made the corrugated to prevent that convection current from taking place simultaneously.
Airbag 13 can cover thin slice synthetic resin thin slice or the coat of metal film of synthetic resin is made by film of synthetic resin, metal, the film of synthetic resin material with its gas release amount and the amount of penetrating is little and rigidity is high material for well, for example polypropylene, poly terephthalic acid diethylester, polyester, polycarbonate, polystyrene, hard PVC, polyamide etc., the thickness of film of synthetic resin with 0.05~1.0mm for well.The metal coverlay is through being formed by stacking with metallic papers such as aluminium foil and above-mentioned film of synthetic resin.The coat of metal film of synthetic resin be with metal vacuum spraying platings such as aluminium to above-mentioned synthetic tree film and make.
Sealed-in gas 14 in the airbag 13, its permeability to heat k is than air (2.41 * 10 2Wm -1K -10 ℃) little, thereby available unreactable gas xenon (k=0.52 * 10 2Wm -1K -10 ℃), krypton (k=0.87 * 10 2Wm -1K -10 ℃), argon (k=1.63 * 10 2Wm -1K -10 ℃) in one of or its miscellaneous gas, because of the permeability to heat of xenon, krypton, argon is little, do not have the problem in the environmental protection during use, be particularly suitable for.
The thickness of thermal insulating material 15 is below 15mm, if thickness is during greater than 5mm, convection current easily take place internal gas 14, and thermal insulating material 15 can increase at its horizontal capacity of heat transmission, and reduces adiabatic efficiency/adia.eff., and the Volumetric efficiency of thermal insulating material 15 just can not get actv. and improves.
In addition, this thermal insulating material 15 is not limited to 1, and available a plurality of superimposed uses also can be used in combination with former isocyanurate foam or styrofoam.
Manufacture method about heat baffle 11, at first produce synthetic resin sheet material 12a, 12b with suitable methods such as injection moldings, then when their engaged at end is got up to make sandwich structural body 12, the thermal insulating material 15 that other is made inserts, airbag 13 that perhaps only will not enclose gas inserts between two walls and sheet material 12a and 12b is bonded with each other to after the one again, and gases such as xenon are injected airbag 13 and seal it by pre-designed gas introduction port.
The manufacture method of airbag 13 is earlier with the gluing fold plate 17 of going up of a face of synthetic resin thin slice, then two films are had pleat line 17 in the face of altogether, again its periphery heat-sealing is got up to get final product.
The heat baffle of making like this 11 except the thermal insulating material that can be used as various insulations such as deep freezer, incubation canteen, cold insulation container, also can be used as thermal insulating material used on the various buildings such as general dwelling house, building etc.
This heat baffle 11 when institute's sealed-in gas is the especially little gas of permeability to heat such as xenon, is compared with the thermal insulating material that uses polyurethane foam to do, have under the situation of identical heat-insulating property, its thickness reduces half, and the thickness of heat insulating part dwindles, attenuation, thereby realizes lightweight.
Because the thickness of thermal insulating material is processed into below the 5mm, the film inside face of airbag is made the corrugated that prevents convection current, can prevent the generation of gas convection current in the airbag, thereby improve heat-insulating property.
In addition, in the present embodiment, in plastic sandwich structural body 12, insert thermal insulating material 15, heat baffle 11 is made lath-shaped, but be not limited to this shape, also be applicable to sandwich structural body or the multilayer wall construction body of making different shape.And airbag 13 or heat baffle 11 can be with two-layer above stacked usefulness, and so, though thickness has increased, its heat-insulating property is higher.
