Definitions
- the invention relates to an insulating device for insulating a usable space from the outside environment and a method for producing an insulating device.
- a container for storing a liquefied gas is known from the prior art, which is also referred to as a Dewar flask and which is used for storing and transporting a liquefied gas or another, preferably free-flowing, substance at a temperature which is considerably lower than typical room temperature of 20 degrees Celsius, in particular in the range from minus 150 degrees Celsius to minus 200 degrees Celsius, can be used.
- the object of the invention is to provide an insulating device with improved insulating properties and a method for producing an inner shell for such an insulating device.
- the insulating device has an inner shell which borders a usable space and which is surrounded by an outer shell, the inner shell being movably accommodated in the outer shell and delimiting an insulating space with the outer shell, and the inner shell being assigned a superconductor device , and with a magnet device assigned to the outer shell, which is designed for a force-transmitting interaction with the superconductor device for the contactless provision of supporting forces for the inner shell.
- the usable space bordered by the inner shell has at least one opening, so that the usable space can be used, for example, to store a liquefied gas, which can be filled into the usable space through this opening or removed from the usable space through this opening.
- the usable space has a plurality of openings, in particular at the end regions of the usable space facing away from one another, and can hereby be used, for example, in the manner of a pipeline for passing on a liquefied gas.
- the inner shell is made of a material that is made in such a way that substances can be stored and transported that have a temperature of 100 Kelvin or less without the material of the inner shell becoming brittle, which would jeopardize the function of the inner shell would .
- the inner shell at most undergoes an elastic deformation and is not plastically deformed or cracks, at least within the scope of the intended use and taking into account the overpressure that may be present in the usable space and/or taking into account the mass of the fluid to be accommodated in the usable space kicks .
- the inner shell is preferably designed in such a way that it can be regarded as dimensionally stable or shape-fixed when the insulating device is used as intended.
- the outer shell has similar properties to the inner shell, it is preferably provided that the outer shell also undergoes at most elastic deformations when the insulating device is used as intended and can be regarded as dimensionally stable or dimensionally stable.
- the task of the outer shell is to one in providing mechanical protection for the inner shell and for an insulating space formed between the inner shell and the outer shell.
- the outer shell has the task of carrying one or more magnet devices, preferably a permanent magnet device, which are designed for force-transmitting interaction with a magnet device assigned to the inner shell, in particular a permanent magnet device and/or a superconductor device.
- the magnetic device assigned to the inner shell can optionally be fixed, in particular partially, in the usable space and thus on an inner surface of the inner shell and/outside the usable space and thus on an outer surface of the inner shell.
- the superconductor device is at least partially integrated into the material of the inner shell.
- the purpose of the magnetic device assigned to the inner shell is to interact with the magnetic device of the outer shell in a force-transmitting manner in order to enable contactless provision of supporting forces for the inner shell.
- This force-transmitting interaction between the magnetic devices allows a mechanical contact between the inner shell and the outer shell to be reduced to a minimum, in particular to zero.
- convective heat conduction from the outer shell to the inner shell is reduced to a minimum, with the result that a long-lasting insulating effect can be achieved by the insulating device.
- the superconductor device which is assigned to the inner shell and is designed as part of the inner shell in one embodiment, preferably comprises at least one so-called high-temperature superconductor or type II superconductor, i.e.
- a superconductor material is YBCO (yttrium barium copper oxide), whose transition temperature is minus 181 degrees Celsius and which, for example, has superconducting properties when cooled by liquefied nitrogen, which has a temperature of less than minus 192 degrees Celsius - points .
- the inner shell before the insulating device is put into operation, in particular before a liquefied gas is supplied, which has a temperature below the transition temperature of the superconductor device, using suitable means, in particular by applying external forces, is brought into a functional onsposition.
- the inner shell should also assume this functional position in relation to the outer shell during subsequent intended use, or it is intended that this functional position be at least in close spatial proximity to a desired functional position for the inner shell in relation to the outer shell.
- the superconductor device is programmed to a certain extent for the magnetic flux provided by the magnet device. If the temperature of the superconductor device subsequently remains below the material-specific transition temperature, the superconductor device, when the inner shell is deflected from the "programmed" functional position, provides reaction forces in interaction with the magnetic device, which ensure that that the inner shell remains at least substantially in the desired functional position.
- the aforementioned effect of "programming" the superconductor device is also referred to as pinning, in which case eddy current flow tubes are caused in the superconductor device, which, due to the superconducting properties of the material of the superconductor device, can be maintained without loss until the superconductor device is again above its material-specific transition temperature
- the advantage of using superconducting material is that, in interaction with the magnetic device of the outer shell, stable positioning for the inner shell relative to the outer shell can be effected, without a control or regulation or an energy supply being required for this.
- the insulating space between the inner shell and the outer shell is gas-tight, in particular evacuated.
- the gas-tight insulation space is at least largely evacuated, so that the number of molecules in the insulation space is minimal compared to an environmental situation for the insulation device in which atmospheric conditions prevail.
- a support element that is elastic or deformable when the temperature drops below the material-specific transition temperature of the superconductor device is arranged in the insulating space between the inner shell and the outer shell and is designed to support the weight of the inner shell.
- the task of the support element is to bring the inner shell into a position relative to the outer shell that is at least essentially the functional position for the inner shell relative to the outer shell after a material or fluid has been supplied, the temperature of which is below the transition temperature for the superconductor device.
- the support element is preferably made of a material that has a high thermal resistance and thus a low coefficient of thermal conductivity.
- the support element is preferably dimensioned such that it can hold the inner shell in a position before the insulating device is put into operation, which at least essentially corresponds to a later position of the inner shell relative to the outer shell after the insulating device has been put into operation. Furthermore, it is provided that the support element is designed to be elastically deformable in such a way that a relative movement between the inner shell and the outer shell during the intended use of the insulating device is only impeded to a small extent.
- the supporting element is designed by selecting a suitable material and/or a corresponding geometric design in such a way that at temperatures above the material-specific transition temperature of the superconductor device, it ensures that the weight is supported between the inner shell and the outer shell and at Falling below the material-specific transition temperature of the superconductor device causes a significant, in particular abrupt, shape change carried out with which it is ensured that a conductive coupling between the inner shell and the outer shell that existed before the critical temperature was reached is canceled after the critical temperature has fallen below.
- the support element can be made of two materials with different temperature-dependent coefficients of expansion, so that when the temperature falls below the critical temperature, an internal stress in the support element brings about the desired change in shape.
- the inner shell is formed along a, in particular straight, profile section with a constant profile and that along the profile several, in particular in the same pitch, spaced permanent magnets and / or superconductor elements are provided.
- the inner shell is tubular along the profile section, in particular with a circular profile, and that several permanent magnets and/or superconductor elements are arranged along this straight profile section in order to be able to exert a supporting effect on the inner shell that is as uniform as possible .
- Such an arrangement of a multiplicity of permanent magnets and/or superconductor elements on the inner shell is of particular interest when a length of the profile section of the inner shell is considerably greater than a maximum inner diameter of the inner shell.
- the inner shell is designed as an inner tube and that the outer shell is designed as an outer tube and that the inner tube is connected to the outer tube at each end in a sealing manner.
- the insulating device forms a pipe section through which, for example, a liquefied gas, in particular liquefied nitrogen, can be transported with as little heating as possible.
- a liquefied gas in particular liquefied nitrogen
- an insulating device designed in this way can be used for the fluidly communicating connection between a fluid reservoir and a fluid consumer.
- end regions of the inner pipe that point away from one another are sealingly connected to end regions of the outer pipe that point away from one another Usable space coaxially surrounds .
- the inner shell is designed in the shape of a bottle and has a mouth opening for the usable space, the outer shell designed in the shape of a bottle being sealingly connected to the inner shell in the region of the mouth opening.
- the insulating device serves as a container for receiving a fluid or another flowable substance which has a temperature below the transition temperature of the superconductor device and is intended to remain at this temperature for a longer period of time.
- the substance or the fluid can be filled into the bottle-shaped inner shell through the mouth opening, with a cross section of the mouth opening being considerably smaller than a cross section of the adjoining container section of the inner shell.

- a superconductor arrangement 6 is arranged on an inner surface 30 of the inner shell 2 , while a permanent magnet device 7 is arranged on an outer surface 31 of the inner shell 2 .
- the superconductor arrangement 6 comprises, purely by way of example, two cuboid superconductor elements 35 which are arranged on the base region 26 .
- the permanent magnet device 7 comprises, purely by way of example, four permanent magnets 36 which are arranged on the side wall 25 so as to protrude radially outwards.
- permanent magnets 37 embodied in a playful cuboid manner are arranged both on the side wall 20 and on the bottom area 21 .
- a total of six permanent magnets 37 are arranged on the outer shell, with the permanent magnets 37 arranged on the bottom area 21 being arranged vertically below the superconductor elements 35 as shown in FIG.
- the attached to the side wall 20 Permanent magnets 37 are arranged in the radial direction outwards adjacent to the permanent magnets 36 of the inner shell 2 , but are at a smaller distance from the bottom area 21 than the permanent magnets 36 .
- the bottle-shaped inner shell When the bottle-shaped inner shell is filled with a substance that has a temperature below the transition temperature of the superconductor elements 35, the superconductor elements 35 on the bottom area 26 of the inner shell 2 are put into a superconducting state through contact with the substance, whereby the magnetic fields of the permanent magnets 37 arranged opposite on the bottom area 21 of the outer shell 3 are stored by pinning in the superconductor elements 35 .
- the increasing weight causes an elastic deformation of the support element 12 and thus a change in the distance between the superconductor elements 35 and the permanent magnets 37 located opposite, resulting in reaction forces between the superconductor elements 35 and the permanent magnets 37 are caused to counteract this linear displacement of the inner hull le.
- the permanent magnets 36 which are slightly spaced apart in the vertical direction, and the permanent magnets 37 attached to the side wall of the outer shell 3 interact magnetically and thus form a magnetically prestressed system. If the weight of the inner shell 2 increases further as a result of further filling with the cold substance, a possible linear displacement of the inner shell 2 in relation to the outer shell 3 leads to an increase in the magnetic interaction between the permanent magnets 36 and 37, so that an additional supporting effect in vertical direction for the inner shell 2 is caused.
- the superconductor elements 35, the permanent magnets 36 and 37, the support element 12 and the sealing element 16 are preferably matched to one another in such a way that the majority of the support forces for the inner shell are caused by contactless magnetic interaction between the superconductor device 6 and the permanent magnet device 7. It can thereby be achieved that the support element 12 and the sealing element 16 are as filigree or can be made thin-walled and thus allow only a small amount of heat input into the insulating space 5 .
- the same reference symbols are used for functionally identical components as in the first embodiment according to FIG.
- the inner shell 2 of the insulating device 41 is equipped exclusively with superconductor elements 35 .
- a support element 42 is provided, which is shaped in the manner of a rotationally symmetrical bellows.
- the support element 42 is preferably made of a material or a combination of materials which causes the support element 42 to shorten when the temperature falls below a predeterminable value, in particular when the critical temperature of the superconductors 35 is undershot.
- the support element 42 is attached to the underside of the inner shell 2, a support effect by the support element 42 and thus a thermally conductive coupling between the inner shell 2 and the outer shell 3 can be canceled as soon as a cold substance is poured into the usable space 4 of the inner shell 2, the transition temperature of the superconductors 35 is undershot and the superconductors 35 are in magnetic interaction with the permanent magnets 37, so that the inner shell 2 is no longer supported by the support element 42. If the inner shell 2 at a later time - point again heated above the transition temperature of the superconductors 35, the length of the support element 42 also changes back to the linear expansion as shown in FIG. The support of the inner shell 2 is thus again guaranteed by the support element 42 at this point in time.
- the insulating device 51 differs from the insulating device 1 in that the inner shell 52 is made of a composite material, not shown in detail, for example as a winding body. It is provided that the composite material of the inner shell 52 contains a predeterminable proportion of superconducting material, so that no additional superconductor elements are required to bring about a magnetic interaction between the inner shell 52 and the permanent magnets 37 on the outer shell 3 .
- permanent magnets 36 can be provided on the inside at the bottom of the inner sleeve 52 and on the outer surface 31 of the inner sleeve 52 . These are provided for a magnetic interaction with permanent magnets 37 which are each arranged adjacent to the permanent magnets 36 and are partly also fixed to the outer surface of the outer shell 3 .
- the insulating device 61 is designed as a pipeline section in which both the inner shell 62 and the outer shell 63 along a profile section 73 have a constant For example, have a circular profile.
- sealing connections between the inner shell 62 and the outer shell 63 are provided at mutually opposite end regions of the insulating device 61 , each using a sealing element 16 .
- superconductor elements 68 embodied purely as an example in the shape of a circular ring, preferably in a uniform division along the axis of symmetry 11 , are arranged.
- Permanent magnets 69 are arranged in the radial direction opposite to the superconductor elements 68 , which are embodied as ring magnets, for example, and which are fixed to an inner surface 74 of the outer shell 63 .
- the insulating film arrangement 76 is adapted to the diameter of the inner sleeve 62 and the outer sleeve 63, which is reduced compared to the other insulating devices 1, 41 and 51.
