Description
SPECIFICATION
A heat insulating device
The invention relates to a heat insulation device in accordance with the preamble of Claim 1.
Heat insulation devices of this type are used in power engineering, in particular in the case of equipment in which heat losses are to be avoided.
tnteralia, heat insulation devices are used in the case of high-temperature storage batteries on the basis of alkaline metal and chalkogen. The storage cells are surrounded by a thermal insulation device in order to prevent them from cooling particularly during the shutdown periods of the high temperature storage battery in order that there is also a temperature of approximately 3500C in the storage cells after the pauses, which is a necessary prerequisite for the optimum functioning of the storage cells.
The German Offenlegungsschrift 30 83 142 discloses a heat insulation device with a doublewalled housing, between the two housing walls of which an evacuated space is provided which is completely filled with at least one insulating material. In this connection two infrared optical opacifiers are used as insulating material, in particular magnetite and titanium oxide. The disadvantage in this case is that when the outer housing wall is damaged, in particular when it is torn open, the effect of the heat insulation is completely lost. If the heat insulation device is used with a storage battery which is used as a source of electrical power for an electric vehicle, the possibility of the insulation device being damaged in an accident cannot be excluded.This causes the immediate loss of the heat insulation, as a result of which the functioning ability of the battery is lost since the operating temperature of 3500C, in particular during shut-down intervals, can no longer be maintained.
The invention is therefore based on the object of providing a heat insulation device with which the heat balance in the interior may be maintained in the desired manner even when there is partial damage.
In accordance with the invention this object is achieved by the features of Claim 1.
In accordance with the invention, a plurality of heat insulating cushions is disposed in the space between the two walls of the housing. Preferably at least 4 to 1 5 layers of these heat insulating cushions are arranged around the inner housing wall, in particular they are wound around it.
The cover of each heat insulating cushion is manufactured from aluminium or a heat-resistant steel. Preferably, two sheets of the abovementioned materials are hermetically welded or soldered together. Each heat insulating cushion is completely evacuated and filled up with at least one insulating material. Two powdery infrared optical opacifiers which have mixed together may be used for this purpose. Titanium oxide and iron oxide (magnetite) are particularly suitable for this purpose. The size of the particles of the titanium oxide should be at most 0.01 ym. The size of the particles of iron oxide should not exceed 0.2 ssm.
Glass- or ceramic fibre paper arranged in a plurality of layers inside the heat insulating cushion may be used as insulating material instead of these two infrared optical opacifiers.
Preferably an intermediate layer of glass silk fibres is arranged between each two successive layers of glass-or ceramic fibre paper.
The heat insulation device according to the invention has an unexpectedly simple construction which enables this heat insulation device to be mass produced in an easy manner. The heat insulation occurs solely by means of the heat insulation cushions such that the housing of the insulation device does not have to be constructed such that it is gastight. The heat insulating cushions are also produced easily since the outer cover of the cushions is formed by two sheets, between which the insulating material is arranged and which may be welded together by known methods. It is also possible to evacuate the cushions easily by means of the apparatus belonging to the prior art. If there is partial damage to the housing forming the insulation device, the heat insulating effect is not lost.The number of heat insulating cushions disposed around the inner housing wall is selected such that adequate insulation of the inner region is insured even when a number of the heat insulating cushions arranged further towards the exterior are damaged.
Embodiments of the invention are hereinafter described with reference to the accompanying drawings, in which:
Figure 1 shows a vertical section through a heat insulation device for a high-temperature storage battery;
Figure 2 shows a heat insulating cushion in section;
Figure 3 shows a further heat insulating cushion in section;
Figure 4 shows the production of a heat insulating cushion; and
Figure 5 shows a pipeline surrounded by the insulation device according to the invention.
Figure 1 shows a heat insulation device 1 which is defined by a double-walled housing 2.
This is square and has an inner space 3 which, for example, is suitable for accommodating electrochemical storage cells 31. Outer and inner housing walls 2A and 2B are made from a heatresistant steel. For reasons of weight the thickness of their walls is not too great. The thickness thereof is 0:2 to 1 mm preferably 0.4 to 0.7 mm.
The outer and inner housing walls 2A and 2B are arranged at a predetermined distance from one another such that a space 6 is formed therebetween. The size of the distance between the outer and inner housing walls 2A and 2B depends upon the desired width of this space 6. Heat insulating cushions 7 are arranged inside this space 6. As may be seen from Figure 1, the heat insulating cushions are disposed around the inner housing wall 2B. Preferably, between 4 and 15 of such heat insulating cushions are arranged, in particular wound, around the inner housing wall 2B.
Figure 2 shows a section of a heat insulating cushion 7 of this type. An outer cover 8 of the heat insulating cushion 7 is preferably formed by two aluminium sheets 8A and 8B. Instead of these aluminium sheets, sheets of heat-resistant steel or high-grade steel may be used. The production method of these heat insulating cushions 7 will be explained hereinafter in greater detail. The heat insulating cushions 7 are inserted in the space 6 such that the two sheets 8A and 8B are arranged perpendicular to the temperature gradients. The two sheets are approximately 0.05 to 0.2 mm preferably 0.1 to 0.2 mm thick. In addition, the two sheets have the same dimensions. The total thickness of a heat insulating cushion 7 of this type, including the two sheets 8A and 8B, is between 0.2 and 0.6 mm.The insulating material 9 is arranged between the two sheets. In the case of the embodiment illustrated in Figure 2, the insulating material is formed by two powdery infrared optical opacifiers 10 and 11 which have been mixed together. The infrared optical opacifier 10 is magnetite (Fe304), which has needle-shaped crystals. These crystals are preferably arranged such that they extend perpendicular to the temperature gradients. Titanium oxide is used as the second infrared optical opacifier. The two infrared optical opacifiers may be contained in the heat insulating cushion in a mixing ratio of 1:1. In addition the heat insulating cushion 7 is evacuated such that a maximum residual gas pressure of 1 to 10 mbar remains in the interior thereof.In order to ensure that the heat insulating cushion is evacuated for a long period of time, the cushion may also contain a getter material (not illustrated here).
Figure 3 shows a further heat insulating cushion 7 which is likewise defined by two metal sheets 8A and SB. The two sheets likewise are of the above-mentioned thickness and are of the same size. At their edge regions, wherein they are in contact with one another, they are welded together. The insulating material 9 is again disposed between the two sheets 8A and 8B. In the case of the embodiment illustrated here the insulating material 9 is formed by glass- or ceramic fibre paper 12. A plurality of papers of this type is arranged such that the papers are at predetermined distances from, and parallel to one another and parallel to the sheets 8A and 8B. In order to obtain optimum insulation, no punctiform or flat contact should form between two successive papers 12.In order to ensure this, at least one intermediate layer 13 is arranged between each two successive papers 12. In the embodiment shown here, this intermediate layer 13 is formed by a layer 13 of glass silk fabric.
The production of a heat insulating cushion 7 of this type is illustrated in Figure 4. Two sheets 8A and 8B of aluminium or high-grade steel, in particular a heat-resistant steel, are used to produce the heat insulating cushion 7. The two sheets are of the same size. Preferably they are quadrilateral, in particular rectangular. The insulating material 9 is disposed between the two sheets 8A and 8B. The size of the sheets 8A and 8B is selected such that they cover the insulating material 9 well. The insulating material 9 may consist of the materials described above or of some other material suitable for this purpose.At their edge regions, at which they are in contact with one another, the two sheets 8A and 8B are permanently connected to one another along the dotted line 15. Preferably, the two sheets are hermetically connected to one another by means of a rolled seam weld. In addition, a pipe 16 is welded in, in a leaktight manner, between the two sheets 8A and 8B. A second pipe 17 is inserted in this pipe 16, which pipe 17 projects as far as the insulating material 9 (not shown here). A rubber hose 18 is pushed over the two pipes 1 6 and 17 and sits firmly on the pipe 16 and the pipe 17. A vacuum pump (not shown here) is connected to the hose 18. When the two sheets have been rigidly connected to one another, the space between them is evacuated.During this process, the heat insulating cushion 7 is maintained at a temperature which is approximately the same as the operating temperature of the electrochemical storage cells 31 or of some other apparatus disposed inside the space 6 of the heat insulating device 1. When the desired vacuum between the sheets has been obtained, the inner pipe 1 7 is drawn towards the exterior until the inner aperture thereof is in a plane with the inner aperture of the outer pipe 1 6. Subsequently, the two sheets 8A and 8B are also hermetically connected to one another in the region which hitherto the pipe 17 penetrated. Thus the inner ragion of the heat insulating cushion 7 is sealed in a gastight manner towards the exterior.The pipes 16 and 17, and the hose 18, which hitherto was still located on the two pipes 1 6 and 17, are now separated from the heat insulating cushion. The producton process is thus concluded.
Figure 5 shows a further embodiment of the heat insulation device 1. In this connection it is disposed about a pipe-line system 20, inside which hot flowing media, such as gases, for example, are transported. Figure 5 shows only a limited section of this pipeline system 20. The heat insulation device also comprises a space 6 in this case, which space 6 is defined by an inner and an outer housing wall. The space 6 is defined by two pipes 21 and 22 which have different diameters. In particular the pipe 21 with the smaller diameter is disposed concentrically inside the pipe 22. As a result of this a uniform intermediate space is provided between the two pipes 21 and 22, which is used as the space 6 for the heat insulating device 1. A plurality of heat insulating cushions 7 is again disposed inside the space 6. Preferably, the heat insulating cushions 7 are wound in a plurality of layers about the inner pipe 21,so that it is surrounded by a plurality of heat insulating cushions 7. These heat insulating cushions 7 are constructed in the manner described above. The insulating material 9 inside these heat insulating cushions 7 may consist, for example, of two infrared optical opacifiers or of glass- or ceramic fibre paper.
The invention is not only limited to the embodiments illustrated in Figures 1 and 5, on the contrary it includes all heat insulating devices comprising a double-walled housing, between the two housing walls of which heat insulating cushions are arranged.
