Description

The invention relates to a cladding unit, in particular for boilers, hot water tanks, buffer storage, heat and / or cold generators, heat and / or cold storage for their thermal insulation.

The DE 10 2006 050 939 A1 describes a generic, heat-insulating casing for body, in particular for hot water tank. The sheath consists of a sleeve enveloping the respective body with a heat-insulating layer of an originally flat foam plate, which is provided on the outside with a cover layer of a sheath with a higher tensile strength. On the inside of the originally flat foam plate to the outer heat-insulating layer to softer layer is arranged. So that the rigid foam plate can be bent around the body, it has on its inside longitudinally extending, wedge-shaped recesses. At the free longitudinal edges of the sleeve, the longitudinal edges connecting fastening devices are provided. This heat-insulating casing has been well proven in practice, but could not be achieved in all applications, a sufficient insulation effect.

From the EP 2 700 886 A2 a hot water storage has become known in which the storage container is surrounded by both a conventional Dämmmmantel and a vacuum insulating panel. The attachment of the thermal insulation of the hot water tank is such that the storage container is first surrounded by the vacuum insulating panel and then the storage container is coated with the already attached vacuum insulating panel by means of Dämmmantels. The vacuum insulation panel consists of a plate with notches, so as to be able to cover the storage tank with the vacuum insulation panel. The disadvantage here is that the vacuum insulation panel, in particular its vacuum-tight outer skin, easily damaged and therefore can be leaking, causing the otherwise good insulation or insulation is lost.

The object of the present invention was to overcome the disadvantages of the prior art and to provide a cladding unit, by means of which a high thermal insulating effect or thermal insulation effect can be achieved with the same wall thicknesses as possible. Furthermore, the risk of damage to individual components of the wrapping unit should be reduced. In addition, but also the installation of the wrapping unit to be insulated or insulated body to be simplified.

This object is achieved by a wrapping unit according to the claims.

The wrapping unit designed according to the invention serves in particular for wrapping or sheathing of boilers, hot water storage tanks, buffer storage tanks, heat and / or cold generators, heat and / or cold storage for their thermal insulation or thermal insulation, wherein the cladding unit may comprise at least the following components:

• - An outer insulating layer having an outer surface and a spaced in a Dämmschichtdicke arranged inner surface, wherein starting from the inner surface in the direction of the outer surface a plurality of wedge-shaped grooves are arranged, each with mutually facing groove surfaces in the outer insulating layer, wherein the grooves each in the wrapping direction spaced from each other, and wherein on the inner surface of the outer insulating layer in the undeformed, planar position between each mutually facing groove surfaces of each of the grooves, a free groove width is formed;
• An inner insulating layer, which inner insulating layer is arranged on the inner surface of the outer insulating layer, in particular at least partially connected to the outer insulating layer, wherein the two insulating layers define a lower longitudinal end face and an upper longitudinal end face and in the region of mutually zuwendbaren end between each of the lower longitudinal end surface and the upper longitudinal end surface extends a transverse end face;
• - An outer lining, which outer lining is arranged on the outer surface of the outer insulating layer;
• A closure device, which closure device is arranged on mutually facing ends of the outer lining, wherein
• - The outer insulating layer has on its inner surface at least one extending in the direction of the outer surface recess;
• - At least one vacuum-insulating panel is provided, which has at least one vacuum insulating panel in its undeformed, planar position a longitudinal dimension and at right angles to extending width dimension and a panel thickness, wherein the width dimension in the parallel direction with respect to the transverse end faces extends and the longitudinal dimension extends in a parallel direction with respect to the longitudinal end faces;
• - The at least one vacuum insulating panel is arranged in the at least one recess;
• - The at least one recess in the undeformed, planar position of the insulating layers has a recess length, which recess length of a sum formed from the Longitudinal dimension of the at least one vacuum-insulating panel plus a sum of groove widths of those grooves corresponds to which grooves are covered by the at least one vacuum-insulating panel in located in a Dämmstellung insulation layers.

The advantage achieved thereby is that, in the case of the wrapping unit according to the invention, the outer insulating layer with the wedge-shaped grooves or notches or recesses arranged or formed therein can be achieved with an insulating position curved around the wedge-size insulating body around the thermally insulated or insulating body. The additional provision of at least one vacuum insulating panel, the insulating effect of the entire enclosure unit can be significantly improved. By providing an additional recess arranged in the region of the inner surface of the outer cover layer, the vacuum insulation panel can thus be accommodated within the wall thickness of the outer insulating layer, without an increase in the wall thickness and, in addition, being covered by the two insulating layers. By the predetermined choice of the recess length of the recess in the planar position of the insulating layers, it is possible to use the vacuum insulating panel in the recess can, so that it is located within the insulation thickness of the outer insulating layer. Thus, due to the mostly planar or aligned orientation of zuwendbaren to be insulated or insulating body inner surface of the vacuum insulating panel and the inner surface of the outer insulating layer, the inner insulating layer without any step formation in the still undeformed, planar position of the insulating layers also planar be arranged on it. Due to the predetermined recess length, which in the planar position of the insulating layers with respect to the longitudinal dimension of the vacuum insulating panel has greater longitudinal extent, so on the one hand when attaching the wrapping unit on the body to be wrapped, the vacuum insulating panel curved and additionally the closing the arranged in the outer insulating layer wedge-shaped grooves made so far until each of their mutually facing groove surfaces come into contact with each other. By arranging and receiving the vacuum insulating panel in the recess of the outer insulating layer can be dispensed with during mounting additional holding and Justiervorgänge, since the vacuum insulating panel forms an integral part or component of the wrapping unit.

Furthermore, it may be advantageous if the recess length of the at least one recess in the undeformed, planar layer of the insulating layers is chosen such that the at least one recess ends in front of the two transverse end faces of the outer insulating layer. This can also be ensured at the mutually turnable ends or mutually zuwendbaren end portions of the wrapping unit, that the vacuum insulating panel is always located within the outer insulating layer and the same damage can be prevented in these sections.

Another embodiment is characterized in that the recess length of the at least one recess in the undeformed, planar layer of the insulating layers is selected such that the at least one recess ends in each case at the two transverse end faces of the outer insulating layer. As a result, an even higher and better thermal insulating or insulating effect and, associated therewith, a lower energy transport between the body to be wrapped and the outer atmosphere surrounding the body can be achieved.

Another possible embodiment has the features that the at least one recess in the undeformed, planar layer of the insulating layers has a recess width, which recess width corresponds to the width dimension of the at least one vacuum insulating panel. Thus, in the insulating or insulating position, a stationary positioning of the vacuum insulating panel can be achieved in the arranged in the outer insulating layer recess. Since preferably the recess width, which extends in the direction of the longitudinal axis of the memory to be enveloped and thus also in the direction of the cladding unit, is shorter than the height or longitudinal extension of the two transverse end faces of the outer insulating layer, so can also the vacuum-insulating panel the edge areas facing the lower as well as the upper longitudinal end face may also be arranged protected inside the outer insulating layer.

A further embodiment provides that the at least one recess in the undeformed, planar layer of the insulating layers has a recess depth, which recess depth corresponds to the panel thickness of the at least one vacuum insulating panel. By matching the recess depth with respect to the panel thickness of the vacuum insulation panel, a projection of the vacuum insulation panel over the inner surface of the outer insulation layer can be prevented. This creates the possibility of being able to arrange the inner insulating layer steplessly over the inner surface defined by the outer insulating layer. Thus, a planar system of the wrapping unit on the outer skin or the Outside surface of the body to be wrapped, in particular the memory created.

Another embodiment is characterized in that the at least one vacuum insulating panel is connected to the outer insulating layer only in at least one connecting section situated in half the longitudinal dimension of the at least one vacuum insulating panel. Due to the choice and position of the connecting portion between the vacuum insulating panel and the base of the outer insulating layer can be provided within certain limits, a holder or relative fixation of the vacuum insulating panel relative to the recess in the outer insulating layer.

Furthermore, it may be advantageous if the connecting portion extends continuously over the entire width dimension of the at least one vacuum insulating panel. Thus, an even more stable and permanent connection between the vacuum insulation panel and the outer insulation layer can be created.

Another alternative embodiment is characterized in that the at least one vacuum insulation panel arranged spaced apart in the direction of its longitudinal dimension has a first end and a second end and that the two in the direction of the longitudinal dimension spaced apart from each other with respect to the outer insulating layer in Enveloping direction are received adjustably in their relative position in the at least one recess. In order for a relative displacement possibility in the direction of the longitudinal dimension spaced apart ends of the vacuum insulating panel with respect. The outer insulating layer can be created during the wrapping process. Because of the connecting section on both sides in the circumferential direction freely projecting ends can be as a mutually the mutually facing groove surfaces of the provided in the outer insulation layer grooves in the formation of the curvature of the wrapping unit for their insulation or insulation position can be ensured.

Another possible and possibly alternative embodiment has the features that the at least one vacuum insulating panel is covered over its entire area by the inner insulating layer. Thus, the vacuum insulating panel can be prevented from direct contact with the outer skin or outer surface of the body to be wrapped. By covering so damage especially the vacuum-tight envelope of the vacuum insulation panel can be created.

Another embodiment provides that the inner insulating layer covers at least one of the transverse end faces of the outer insulating layer. Thus, a gap-free cover of the memory or the body can be achieved even in the joint area of the wrapping unit.

Another embodiment is characterized in that at least one insulating element is arranged on at least one of the transverse end faces of the outer insulating layer and that the at least one insulating element is formed from an automatically elastically recoverable material, in particular from a foamed plastic. By providing at least one automatically elastically recoverable trained insulating element in the joint or connecting portion of the wrapping unit so simple manufacturing inaccuracies of the outer insulating layer can be compensated in their longitudinal or circumferential extent and subsequently a gap-free and dense total envelope are created.

Furthermore, it may be advantageous if the at least one insulating element is covered by the inner insulating layer at least on its side facing away from the outer cladding. Due to the additional covering of the at least one insulating element, an even better insulating or sealing effect can be achieved in the area of impact or closure of the wrapping unit.

Another embodiment is characterized in that the at least one vacuum insulating panel is provided on its side facing the inner insulating layer with a plurality of spaced notches in the wrapping direction, which notches have a parallel orientation with respect to the arranged in the outer insulating layer grooves. This makes it possible, even vacuum insulation panels with a greater thickness to spend more easily in a curved envelope position or insulating position.

Another possible embodiment has the features that the outer insulating layer of a foam plate, in particular of a foamed plastic material, is formed. By choosing the appropriate material or material as a tensile and / or pressure-resistant plate can be created, which also has a good thermal insulation and insulation effect.

A further embodiment provides that the respective mutually facing groove surfaces of the individual grooves abut each other in which insulation layers located in the insulation position. This prevents a chimney effect in the area of the mutually facing groove surfaces. As a result, the thermal insulation or insulating effect can be further improved.

Finally, another embodiment is characterized in that the inner insulating layer is formed of a multi-layer sheet of a nonwoven fabric of fibers. By choosing the material of the inner insulating layer so a cuddly and to be applied to the insulating or insulating body or memory layer to be created, which is easily compressible within certain limits and thereby a gap-free thermal insulation or insulation of the wrapping unit can be created ,

The term "in particular" is understood below to mean that it may be a possible more specific training or specification of an object or a method step, but not necessarily a compelling, preferred embodiment of the same or a compelling approach.

In the 1 to 4 is a serving unit 1 shown, which are attached as cladding for body, in particular boiler, hot water tank, buffer storage, heat and / or cold generators, heat and / or cold storage to the thermal insulation of it. The bodies are mostly cylindrically shaped containers, which can still be provided with connections or connecting pieces not shown in detail. The cross-sectional shape of the body in a mostly horizontal sectional plane need not be cylindrical, but may also be polygonal, oval or even have a different cross-section. Subsequently, the body is generally called memory 2 designated. The body or the memory 2 is mostly supported on a flat footprint and has a vertical extent. Furthermore, the memory can 2 also a longitudinal axis 3 define which in the state of installation of the body or the memory 2 preferably oriented vertically.

The serving unit 1 may be formed of several individual components or individual components, which are described here only in general, the detailed description thereof is made in more detail in the following figures.

Basically, the wrapping or sheathing of the memory takes place 2 such that the wrapping unit 1 is manufactured as a planar unit and this as a jacket or cuff around the outer surface of the memory 2 is beaten or wrapped. The circumferential wrapping or wrapping of the memory 2 in a direction perpendicular to the generally vertically aligned longitudinal axis 3 extending plane is hereinafter referred to as wrapping direction or circumferential direction. Is the body or the memory 2 from the serving unit 1 At least on its outer surface or its outer skin wrapped and thus also to a predominant area ratio, but preferably completely covered by it, this position of the wrapping unit 1 referred to as Dämmstellung or as an insulating position or as a wrapping position. In this case, mutually facing end portions of the wrapping unit 1 connected together to form a related assembly.

Is the wrapping unit located 1 in their insulating or insulating position or wrapping position, a separate longitudinal axis is also defined by this. For simplicity, the same reference numeral is used for this own longitudinal axis, as previously for the memory 2 or body has been described. The longitudinal axis 3 of the memory 2 or body as well as the own longitudinal axis the serving unit 1 if this is in its insulating or insulating position or wrapping position or is erected to it, preferably arranged congruently to each other.

Basically, the wrapping unit serves 1 as an insulating material to reduce the passage of heat energy, so the memory 2 or body to protect against cooling or warming. The insulating or insulating position or wrapping position can also be referred to as thermal insulation position.

In the present embodiment, the wrapping unit comprises 1 at least one outer layer of insulation 4 , an inner layer of insulation 5 , an outer lining 6 and a closure device 7 , The outer insulation layer 4 is formed in the present embodiment of a foam plate, in particular of a foamed plastic material. Thus, for example, a rigid polyurethane foam (PUR), polystyrene rigid foam (PS), expanded polystyrene (EPS), extruded polystyrene (XPS) or other rigid, preferably closed-cell, plastic materials, which also have insulating or insulating properties could be used as the plastic material , Usually, the wrapping unit becomes 1 before attaching to the store 2 manufactured in an undeformed, planar starting position and only when applied to or around the body or memory 2 in a respect to the longitudinal axis 3 curved position or position deformed.

To ensure a good, gap-free nestling of the wrapping unit 1 , in particular the outer insulating layer 4 , at the store 2 can achieve the inner insulating layer 5 be provided. This can be formed of a multi-ply sheet, of a nonwoven fabric of fibers.

It can also be seen that the inner insulating layer 5 on the side of the outer insulation layer 4 is arranged, which the memory 2 or its longitudinal axis 3 is turned.

The outer lining 6 which the outer insulation layer 4 to a large extent or even completely covers, can be formed from a variety of materials, such as films, fabrics or knitted or thin, plate-shaped materials or components. The outer lining 6 can be designed as a cladding element or be designated and in the present embodiment, the outer boundary of the cladding unit 1 on theirs from the store 2 averted side dar.

In the 2 to 4 is a first possible and possibly independent embodiment of the wrapping unit 1 without the body or memory 2 shown in a planar, undeformed position or position, again for like parts, the same reference numerals or component names as in the preceding 1 be used. To avoid unnecessary repetition, the detailed description in the previous one 1 referred or referred.

As described above, in this embodiment, the outer insulating layer 4 formed from a predominantly rigid plastic material. In the flat, undeformed starting position is the outer layer of insulation 4 in its spatial form of an outer surface 8th and an inner surface 9 limited. The inner surface 9 is in an insulating layer thickness 10 from the outside surface 8th arranged distanced.

Since the selected material of the outer insulation layer 4 is designed as rather rigid and this is usually designed as a foam plate, appropriate precautions must be taken to, inter alia, the insulating layer 4 around the store 2 be able to attach in a non-deformed, planar starting position to curved insulating or insulating position. These are in a known manner in the outer insulation layer 4 starting from the inner surface 9 towards the outer surface 8th several wedge-shaped grooves 11 recessed. The individual grooves 11 have a longitudinal extent or a longitudinal course, which thus in a parallel direction with respect to the longitudinal axis 3 of the memory 2 are aligned. Furthermore, the individual grooves 11 by mutually facing groove surfaces 12 limited. Furthermore, the individual grooves 11 each in the wrapping direction, ie in the circumferential direction around the memory 2 to the longitudinal axis 3 spaced around each other.

In the in the 2 illustrated undeformed, planar position of the outer insulating layer 4 is in each case between the mutually facing groove surfaces 12 each of the grooves 11 a free groove width 13 educated. These each free groove widths 13 are in parallel direction with respect to the inner surface 9 , in the vertical direction with respect to the longitudinal extent of each of the individual grooves 11 as well as directly on the inner surface 9 the outer layer of insulation 4 measured.

The inner insulation layer 5 is on the inner surface 9 the outer layer of insulation 4 arranged and thus on that side of the wrapping unit 1 provided which of the outer surface of the memory 2 is turned or zuwendbar. The inner insulation layer 5 can with the outer insulation layer 4 , in particular its inner surface 9 be connected at least in certain areas.

Preferably, both form insulating layers 4 . 5 one of the footprint of the store 2 adaptable lower longitudinal end face 14 and one towards the height of the store 2 , ie in the direction of the longitudinal axis 3 , of which distanced arranged upper longitudinal end face 15 from or define these. The two longitudinal end faces 14 . 15 may also be referred to as peripheral end surfaces when the sheath unit 1 on the outside of the store 2 has been arranged. Furthermore, defines in particular the outer insulation layer 4 and / or the inner insulating layer 5 in the region of end areas which can be turned into one another in the insulating or insulating position, one between the lower longitudinal end face in each case 14 and the upper longitudinal end surface 15 extending transverse end face 16 and 17 , Is the wrapping unit located 1 in their insulating or insulating position, in which they the memory 2 enveloped, the two transverse end surfaces extend 16 . 17 in a parallel direction with respect to the longitudinal axis 3 of the memory 2 and thus in the height direction of the wrapping unit 1 or the memory 2 , The two longitudinal end faces 14 . 15 extend in the insulating or insulating position of the wrapping unit 1 in the circumferential direction and in each case in a direction perpendicular to the longitudinal axis 3 aligned level.

The outer insulation layer 4 is thus in your spatial form through its outer surface 8th , the inner surface 9 and the lower and upper longitudinal end surfaces extending therebetween 14 . 15 as well as the transverse end faces 16 . 17 limited or fixed.

How better off the 2 and 3 can be seen, the outer insulation layer 4 on its inner surface 9 at least one towards the outer surface 8th extending recess 18 on.

The at least one recess 18 is intended that in this at least one vacuum insulating panel 19 can be added or used. The vacuum insulation panel 19 has in its undeformed, planar position a longitudinal dimension 20 and a widthwise dimension extending at right angles thereto 21 on. The vacuum insulation panel 19 Depending on the insulating or insulating effect a selected panel thickness 22 exhibit. The width dimension 21 the vacuum insulation panel 19 extends in parallel direction with respect to the transverse end face 16 . 17 , where the longitudinal dimension 20 in a parallel direction with respect to the two longitudinal end faces 14 . 15 extends.

The above-described at least one recess 18 is provided, the at least one vacuum insulating panel 19 in the outer insulation layer 4 sunk to sink. This is the at least one recess 18 in their dimensions to the at least one vacuum insulation panel to be accommodated therein 19 adapt. Outgoing from the undeformed, planar layer of the insulating layer 4 . 5 has at least one recess 18 a recess length 23 on which at least a sum formed from the longitudinal dimension 20 the at least one vacuum insulating panel 19 plus a sum of groove widths 13 of those grooves, which grooves 11 with insulation layers located in the insulating or insulating position 4 . 5 from the at least one in the recess 18 located vacuum insulation panel 19 are covered.

By circumferentially wrapping or wrapping the memory 2 from the serving unit 1 become the mutually facing groove surfaces 12 the individual grooves 11 with insulation layers located in the insulating or insulating position 4 . 5 put on each other. This takes place in the area of the inner surface 9 a shortening of the recess 18 in the direction of their now curved recess length 23 , This shortened circumferential length of the recess 18 in the insulating or insulating position of the wrapping unit 1 then corresponds to a sum of individual lengths of the material of the outer insulating layer 4 between the individual groove surfaces 12 remaining portions of the material in the same direction.

The recess length 23 the recess 18 is thus dependent on the extended longitudinal dimension 20 the vacuum insulation panel 19 to choose. So can the recess length 23 the at least one recess 18 in the undeformed, level surface of the insulating layers 4 . 5 be chosen such that the at least one recess 18 in front of the two transverse end faces 16 . 17 the outer layer of insulation 4 ends.

Regardless, it would also be possible for the recess length 23 the at least one recess 18 in the undeformed, level surface of the insulating layers 4 . 5 is chosen such that the at least one recess 18 in each case on at least one of the two transverse end faces 16 . 17 , in particular at both of the transverse end faces 16 . 17 , the outer insulating layer 4 ends. To a height support or cover of the vacuum insulation panel 19 in the recess 18 to achieve the at least one recess 18 in the undeformed, level surface of the insulating layers 4 . 5 a recess width 24 which has the width dimension 21 the at least one vacuum insulation panel 19 equivalent. It may be advantageous if the recess width 24 is slightly larger than the width dimension 21 the at least one vacuum insulation panel 19 ,

As from the representation of 3 can still be seen, is the recess width 24 the recess 18 equal to or only slightly larger than the width dimension 21 the vacuum insulation panel 19 to be able to record these safely. Furthermore, the recess width is preferred 24 the recess 18 and thus the width dimension 21 the vacuum insulation panel 19 chosen shorter than a longitudinal extension of the transverse end face 16 . 17 between the lower longitudinal end face 14 and the upper longitudinal end surface 15 , This remains between the recess 18 and the lower longitudinal end surface 14 and also between the recess 18 and the upper longitudinal end surface 15 in each case an edge strip of the outer insulating layer 4 stand and so the inner surface 9 receive. Preferably, the two remaining edge strips can be selected in their width so that a central arrangement of the vacuum insulating panel 19 between the two longitudinal end faces 14 and 15 he follows.

Too far distancing the vacuum insulation panel 19 in which in the at least one recess 18 located position of the inner surface 9 the outer layer of insulation 4 to avoid the at least one recess 18 in the undeformed, level surface of the insulating layers 4 . 5 a recess depth 25 have which of the panel thickness 22 the at least one vacuum insulation panel 19 equivalent. The recess depth 25 is preferably chosen at least so deep that the at least one vacuum insulating panel 19 not over the inner surface 9 towards the store 2 protrudes or the inner surface 9 surmounted.

Is this at least a vacuum-insulated panel 19 in the at least one recess 18 arranged or received, it is advantageous if this of the inner insulating layer 5 full-surface is covered. It is also possible that the inner insulating layer 5 at her the vacuum insulated panel 19 facing side at least in sections with the vacuum insulation panel 19 connected is. But it would also be a full-surface connection between the inner layer of insulation 5 and the vacuum insulation panel 19 possible.

Furthermore, it may be advantageous if the at least one vacuum insulation panel 19 only in at least one, in half a longitudinal dimension 20 the at least one vacuum insulation panel 19 located connecting portion with the outer insulating layer 4 connected is. This approximately centered with respect to the longitudinal dimension 20 provided connection of the vacuum insulation panel 19 with the outer insulation layer 4 thus holds this only in the middle section relative to the outer insulating layer 4 stationary. Furthermore, the connecting portion between the vacuum insulating panel 19 and the base of the recess 18 also throughout the entire width dimension 21 the at least one vacuum insulation panel 19 extend. The connecting portion may be formed approximately strip-shaped.

How better of the 2 can be seen that has at least one vacuum insulating panel 19 in the direction of its longitudinal dimension 20 distanced from each other a first end 26 as well as a second end 27 on. By in the extended or planar position of the two insulating layers 4 . 5 longer than the longitudinal dimension 20 trained recess length 23 the recess 18 , the two should each be in the direction of the longitudinal dimension 20 Distanced from each other ends 26 . 27 concerning the outer insulation layer 4 in the wrapping direction in its relative position in the at least one recess 18 be added adjustable. This makes it possible that in the course of the wrapping process or the wrapping of the memory 2 and the associated circumferential shortening of the recess length 23 by reducing or closing the individual grooves 11 the vacuum insulation panel 19 the shortened recess 18 in the direction of their recess length 23 completely filled out.

It is also possible that at least one of the transverse end faces 16 . 17 the outer layer of insulation 4 at least one additional insulating element 28 is arranged or provided. Preference is given to both of the transverse end faces 16 . 17 each the insulating elements 28 intended. The one or more insulating elements 28 serve to the closure area of the wrapping unit 1 also to be able to thermally insulate or seal well and in addition to be able to compensate for certain manufacturing inaccuracies. For this it is advantageous if the at least one insulating element 28 is formed from an automatically elastically recoverable material, in particular from a foam plastic. Furthermore, this can be at least one insulating element 28 at least on his from the outer lining 6 turned away from the inner layer of insulation 5 be covered. For this purpose, a predetermined longitudinal extent of the inner insulating layer 5 the straight longitudinal extent of the longitudinal end faces 14 . 15 plus the thickness of the at least one additional insulating element 28 to choose.

Depending on the selected panel thickness 22 It may still be beneficial to include the vacuum insulation panel 19 be able to deform from its first planar, undeformed starting position in the insulating or insulating position, if this at least on its inner insulating layer 5 facing side with a plurality of spaced from each other in the wrapping direction notches 29 is provided. The notches 29 are in dotted lines Lines in the 2 in the vacuum insulation panel 19 indicated. The notches 29 preferably have a parallel orientation with respect to in the outer insulating layer 4 arranged grooves 11 on.

The previously written outer lining 6 is preferred on the outer surface 8th the outer layer of insulation 4 arranged. The closure device 7 in turn can be turned towards each other in the insulating or insulating position or already facing ends of the outer lining 6 , In particular its cladding element, be arranged or provided. As a closure device 7 For example, interlocking hook-shaped closure strips, a hook-and-loop fastener or the like could be chosen.

In the 4 is the serving unit 1 simplified illustrated in a radial partial section, wherein the wrapping unit 1 in the insulating or insulating position on the body or the memory 2 is shown in its circumferentially closed position.

Due to the tensile or the tensile stiffness as well as the pressure-resistant or pressure-resistant design of the outer lining 6 and also due to the outer layer of insulation 4 , are those in the outer insulating layer 4 arranged grooves 11 with their mutually facing groove surfaces 12 been brought together for mutual investment. Therefore, the now closed grooves 11 just shown with a simple stroke.

Furthermore, it can be seen that this usually also zugsteif and pressure-resistant formed vacuum insulating panel 19 around the longitudinal axis 3 is arranged curved. The in the direction of the longitudinal dimension 20 spaced apart ends of the vacuum insulation panel 19 are on those side surfaces of the recess 18 moved to the plant or in their immediate vicinity, which side surfaces in the direction of the recess length 23 the recess 18 are distanced from each other. This will be a nearly to complete sheathing of the body or the memory 2 achieved, which is preferably formed gap-free.

Furthermore, the closure device is still simplified 7 shown in their closed position. In this embodiment, in each case at the two transverse end faces 16 . 17 arranged insulation elements 28 , In particular, the associated with these insulating elements 28 , Can be slightly compressed or elastically compressed in the circumferential direction or in the wrapping direction, as well as in the closure region or closure portion of the wrapping unit 1 to form a gap-free enclosure.

In the 5 is another and possibly independent embodiment of the wrapping unit 1 shown, again for like parts, the same reference numerals or component names as in the previous 1 to 3 be used. In order to avoid unnecessary repetition, the detailed description in the previous ones will be used 1 to 3 referred or referred.

Also this sheath unit shown 1 serves for wrapping or sheathing the memory described above 2 or body and includes from the outside to the memory 2 the outer lining 6 , the outer insulation layer 4 as well as the inner insulation layer 5 , In the inner surface 9 the outer layer of insulation 4 in turn, starting from this, the recess described above 18 for holding the vacuum insulation panel 19 intended. Because in the 5 the stretched undeformed position of the wrapping unit 1 is shown and again the grooves described above 11 for easier implementation of the wrapping process in the outer insulating layer 4 are arranged, is the vacuum insulation panel 19 when in the recess 18 position shown shorter in its longitudinal extent than the recess length 23 the recess 18 ,

In contrast to the previously described embodiment of the wrapping unit 1 here is no additional insulation element 28 in the area of the transverse end faces 16 and or 17 the outer layer of insulation 4 arranged. The inner insulation layer 5 covers in the planar undeformed position of the outer insulating layer 4 these on their inner surface 9 over the entire surface and extends at least over one of the transverse end faces 16 and or 17 the outer layer of insulation 4 and covers them with it as well.

At the outer lining 6 , In particular its cladding element, in turn, elements for forming the closure device 7 arranged or provided.

By arranging or providing the inner insulating layer 5 also in the area of at least one of the transverse end face 16 and or 17 the outer layer of insulation 4 can also use this serving unit 1 in their insulating or insulating position in the region of their then mutually facing ends thermally insulating or insulating or sealing together and by means of the closure device 7 held together or connected to each other.
