    The invention relates to a cladding unit, in particular for boilers, hot water storage tanks, buffer storage, heat and / or cold generators, heat and / or cold storage for their thermal insulation.
    DE 10 2006 050 939 A1 describes a generic, heat-insulating casing for the body, in particular for hot water storage. 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 EP 2 700 886 A2 a hot water storage has become known in which the storage container is surrounded by both a conventional Dämmmantel 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 protect the storage tank with the vacuum
    To be able to cover the insulating 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 is used, in particular, for wrapping or sheathing boilers, hot water storage tanks, storage tanks, heat and / or refrigeration generators, thermal and / or cold storage devices for their thermal insulation or thermal insulation, wherein the cladding unit may comprise at least the following components: an outer insulating layer with an outer surface and with an inner surface spaced therefrom in an insulating layer thickness, wherein, starting from the inner surface towards 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 are spaced from one another in the wrapping direction, 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 is formed a free groove width; an inner insulating layer, which inner insulating layer is arranged on the inner surface of the outer insulating layer, in particular with the outer insulating layer is at least partially connected, wherein the two insulating layers define a lower longitudinal end face and an upper longitudinal end face and in the range of mutually zuwendbaren end between each of the lower Länasstirnfläche and the upper Länasstirnfläche a transverse end face extends: an outer lining, which outer lining is disposed on the outer surface of the outer Dämmschicht; 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 recess extending in the direction of the outer surface; 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 a right angle to extending width dimension and a panel thickness, wherein the width dimension extends in a parallel direction with respect to the transverse end faces and the longitudinal dimension extends in a parallel direction with respect to the longitudinal end faces; the at least one vacuum insulating panel is disposed in the at least one recess; the at least one recess in the undeformed, planar layer of the insulating layers has a recess length, which recess length corresponds to a sum formed from the longitudinal dimension of the at least one vacuum insulation panel plus a sum of groove widths of those grooves, which grooves are at least one vacuum Insulating panel are covered with located in a Dämmstellung insulation layers.
    The advantage achieved in this way is that, in the case of the enveloping unit according to the invention, the outer insulating layer with the wedge-shaped grooves or notches or recesses arranged or formed therein can be provided 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. Due to 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 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 the recess width, which extends in the direction of the longitudinal axis of the storage to be enveloped and thus also in the direction of the enveloping unit, is selected to be shorter than the height or longitudinal extent of the two transverse end faces of the outer insulating layer, the vacuum can also be selected. Insulated panel on the lower and the upper longitudinal end face facing edge regions also be protected within 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 contact of the wrapping unit on the outer skin or the outer surface of the body to be wrapped, in particular of the memory can be 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 located 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 can be aeschaffen in particular the vacuum-tight envelope formed the vacuum insulation panel.
    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-apart notches, 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 the appropriate material or. Choice of material can create a tensile and / or pressure-resistant plate who the, which additionally 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. This allows the thermal insulation or. Insulating effect can be additionally 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 ,
    For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

    By way of introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component names, the disclosures contained in the entire description can be mutatis mutandis to the same parts with the same reference numerals or component names. Also, the location information chosen in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and these position information in a change in position mutatis mutandis to transfer to the new location.
    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.
    1 to 4, a wrapping unit 1 is 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. Hereinafter, the body is generally referred to as memory 2. The body or the memory 2 is usually supported on a flat footprint and has a height extent. Furthermore, the memory 2 can also define a longitudinal axis 3, which is preferably oriented vertically in the installation state of the body or the memory 2.
    The wrapping unit 1 can be formed from a plurality of individual components or individual components, which are only described in general here, the detailed description of which takes place in more detail in the following figures.
    Basically, the wrapping or sheathing of the memory 2 takes place in such a way that the sheathing unit 1 is manufactured as a plane-like structural unit and this is wrapped around or wrapped around the outer surface of the memory 2 as a sheath or sleeve. The circumferential enveloping or sheathing of the memory 2 in a plane extending in a vertical direction with respect to the generally vertically oriented longitudinal axis 3 is referred to below as the wrapping direction or circumferential direction. If the body or the storage 2 is enveloped by the wrapping unit 1 at least on its outer surface or its outer skin and thus also predominantly covered by it, this position of the wrapping unit 1 becomes an insulating position or an insulating position or a wrapping position designated. In this case, mutually facing end portions of the wrapping unit 1 are connected together to form a related unit.
    If the wrapping unit 1 is in its insulating or insulating position or wrapping position, this also defines its own longitudinal axis. For simplicity, the same reference numeral is used for this own longitudinal axis, as has been previously described for the memory 2 or body. The longitudinal axis 3 of the memory 2 or body as well as the own longitudinal axis of the wrapping unit 1, when this is in its insulating or insulating position or wrapping position or is erected thereto, are preferably arranged congruently extending to each other.
    Basically, the wrapping unit 1 serves as an insulating material to reduce the passage of heat energy, so as to protect the memory 2 or body from cooling or heating. The insulating or insulating position or wrapping position can also be referred to as thermal insulation position.
    In the present embodiment, the wrapping unit 1 comprises at least one outer insulating layer 4, an inner insulating layer 5, an outer lining 6 and a closure device 7. The outer insulating layer 4 is formed in the present embodiment of a foam plate, in particular of a foamed plastic material. For example, as a plastic material, a rigid polyurethane foam (PUR), polystyrene foam (PS), expanded polystyrene (EPS), extruded polystyrene (XPS) or other rigid, preferably closed-cell, plastic materials, which also have insulating or insulating properties can be used , Usually, the wrapping unit 1 is made prior to attachment to the memory 2 in an undeformed, planar starting position and only when applied to o-the body or memory 2 deformed in a respect to the longitudinal axis 3 curved position or position.
    In order to achieve a good, clot-free nestling of the wrapping unit 1, in particular the outer insulating layer 4, on the memory 2, the inner insulating layer 5 may be provided. This can be formed of a multi-ply sheet, of a nonwoven fabric of fibers.
    Furthermore, it can be seen that the inner insulating layer 5 is arranged on that side of the outer insulating layer 4, which is the memory 2 and its longitudinal axis 3 is facing.
    The outer lining 6, which covers the outer insulating layer 4 to a predominant part or even completely, 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 may be formed as a cladding element or be designated and represents in the present embodiment, the outer boundary of the cladding unit 1 on its side facing away from the memory 2 side.
    FIGS. 2 to 4 show a first possible embodiment of the wrapping unit 1, which may be independent of itself, without the body or storage 2 in a planar, undeformed position or position, wherein the same reference numerals or component designations as in FIG the previous Fig. 1 are used. In order to avoid unnecessary repetition, reference is made to the detailed description in the preceding FIG.
    As described above, in this embodiment, the outer insulating layer 4 is formed of a largely rigid plastic material. In the planar, undeformed starting position, the outer insulating layer 4 is limited in its spatial form by an outer surface 8 and an inner surface 9. The inner surface 9 is arranged in an insulating layer thickness 10 of the outer surface 8 spaced.
    Since the selected material of the outer insulating layer 4 is designed to be rather rigid and this is usually designed as a foam plate, appropriate precautions have to be taken, inter alia, the insulating layer 4 to the memory 2 in a non-deformed, planar starting position to curved Dämm- or To install insulating position. For this purpose, a plurality of wedge-shaped grooves 11 are recessed in a known manner in the outer insulating layer 4, starting from the inner surface 9 in the direction of the outer surface 8. The individual grooves 11 have a longitudinal extension or a longitudinal course, which are thus aligned in a parallel direction with respect to the longitudinal axis 3 of the memory 2. Furthermore, the individual grooves 11 are bounded by mutually facing groove surfaces 12. Furthermore, the individual grooves 11 are each arranged in the wrapping direction, ie in the circumferential direction about the memory 2, spaced from one another about the longitudinal axis 3.
    In the undeformed, planar position of the outer insulating layer 4 shown in FIG. 2, each of the grooves 11 has a free groove width 13 formed between the mutually facing groove surfaces 12. These respective free groove widths 13 are measured in a 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 and directly on the inner surface 9 of the outer insulating layer 4.
    The inner insulating layer 5 is arranged on the inner surface 9 of the outer insulating layer 4 and thus provided on that side of the wrapping unit 1, which is the outer surface of the memory 2 facing or zuwendbar. The inner insulating layer 5 may be connected to the outer insulating layer 4, in particular its inner surface 9, at least partially.
    Preferably, both insulating layers 4, 5 form a lower longitudinal end face 14 which can be turned towards the footprint of the accumulator 2, and an upper longitudinal end face 15 arranged in the direction of the height of the accumulator 2, ie in the direction of the longitudinal axis 3, distanced from it, or define said upper end face 15. The two longitudinal end faces 14, 15 may also be referred to as circumferential end faces when the wrapping unit 1 has been arranged on the outside of the store 2. In addition, in particular the outer insulating layer 4 and / or the inner insulating layer 5 defines in each case an end face 16 extending between the lower longitudinal end face 14 and the upper longitudinal end face 15 in the region of end regions which can be turned towards each other in the insulating or insulating position. If the wrapping unit 1 is located in their insulating or insulating position, in which they surround the memory 2, the two transverse end faces 16,17 extend 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 and 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 aligned in the vertical direction with respect to the longitudinal axis 3 level.
    The outer insulating layer 4 is thus bounded or fixed in its spatial form by its outer surface 8, the inner surface 9 and the lower and upper longitudinal end surfaces 14, 15 extending therebetween and the transverse end surfaces 16, 17.
    As can now better be seen from FIGS. 2 and 3, the outer insulating layer 4 has on its inner surface 9 at least one recess 18 extending in the direction of the outer surface 8.
    The at least one recess 18 is provided so that it can be accommodated or used in this at least one vacuum insulating panel 19. In its undeformed, planar position, the vacuum insulation panel 19 has a longitudinal dimension 20 and a width dimension 21 extending at right angles thereto. The vacuum insulation panel 19 may have a selected panel thickness 22 depending on the insulating or insulating effect. The width dimension 21 of the vacuum insulating panel 19 extends in a parallel direction with respect to the transverse end face 16, 17, the longitudinal dimension 20 extending in a parallel direction with respect to the two longitudinal end faces 14, 15.
    The above-described at least one recess 18 is intended to be able to receive the at least one vacuum insulation panel 19 recessed in the outer insulating layer 4. For this purpose, the dimensions of at least one recess 18 are to be adapted to the at least one vacuum insulation panel 19 to be accommodated therein. Outgoing from the undeformed, planar layer of the insulating layer 4, 5, at least one recess 18 has a recess length 23, which at least a sum formed from the longitudinal dimension 20 of the at least one vacuum insulating panel 19 plus a sum of groove widths 13 of those grooves corresponds to which grooves 11 in itself in the insulation or. Isolation insulating layers located 4, 5 are covered by the at least one located in the recess 18 vacuum insulating panel 19.
    Due to the circumferential wrapping or wrapping of the memory 2 of the wrapping unit 1, each of the mutually facing groove surfaces 12 the individual grooves 11 are applied to each other in the insulation or insulation insulation layers 4, 5. This results in the region of the inner surface 9 a shortening of the recess 18 in the direction of their now curved Ausnehmungslänge 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 of the recess 18 is thus to be selected as a function of the elongated longitudinal dimension 20 of the vacuum insulating panel 19. Thus, the recess length 23 of the at least one recess 18 in the undeformed, planar position of the insulating layers 4, 5 may be selected such that the at least one recess 18 ends before the two transverse end faces 16, 17 of the outer insulating layer 4.
    Regardless, it would also be possible that the recess length 23 of the at least one recess 18 in the undeformed, planar position of the insulating layers 4, 5 is selected such that the at least one recess 18 in each case at least one of the two transverse end surfaces 16, 17, in particular at both of the transverse end faces 16,17, the outer insulating layer 4 ends. In order to achieve a height support or cover of the vacuum insulating panel 19 in the recess 18, the at least one recess 18 in the undeformed, planar position of the insulating layers 4, 5 have a recess width 24, which the width dimension 21 of at least one Vacuum insulating panel 19 corresponds. It may be advantageous if the recess width 24 is chosen to be slightly larger than the width dimension 21 of the at least one vacuum insulating panel 19.
    As can be seen from the illustration of FIG. 3, the recess width 24 of the recess 18 is selected to be equal to or only slightly larger than the width dimension 21 of the vacuum insulating panel 19 in order to be able to safely pick it up. Furthermore, the recess width 24 of the recess 18 and thus also the width dimension 21 of the vacuum insulating panel 19 are preferably shorter than a longitudinal extension of the transverse stop face 16, 17 between the lower longitudinal end face 14 and the upper longitudinal end face 15. Thus remains between the recess 18 and The lower longitudinal end face 14 and also between the recess 18 and the upper longitudinal end face 15 are each an edge strip of the outer insulating layer 4 and thus the inner surface 9 obtained. 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 takes place.
    In order to avoid too far distancing the vacuum insulating panel 19 in the position located in the at least one recess 18 from the inner surface 9 of the outer insulating layer 4, the at least one recess 18 in the undeformed, planar Laae of the insulating layers. 4 5 have a recess depth 25 which corresponds to the panel thickness 22 of the at least one vacuum insulation panel 19. The recess depth 25 is preferably chosen to be at least so deep that the at least one vacuum insulating panel 19 does not protrude beyond the inner surface 9 in the direction of the reservoir 2 or projects beyond the inner surface 9.
    If the at least one vacuum insulation panel 19 is arranged or accommodated in the at least one recess 18, it is advantageous if it is covered by the inner insulating layer 5 over its full area. Furthermore, it is possible for the inner insulating layer 5 to be connected at least in sections to the vacuum insulating panel 19 on its side facing the vacuum insulating panel 19.
    But it would also be a full-surface connection between the inner insulating layer 5 and the vacuum insulating panel 19 possible.
    Furthermore, it may be advantageous if the at least one vacuum insulating panel 19 is connected to the outer insulating layer 4 only in at least one connecting section situated in a half longitudinal dimension 20 of the at least one vacuum insulating panel 19. This provided approximately centrally with respect to the longitudinal dimension 20 connection of the vacuum insulating panel 19 with the outer insulating layer 4 thus holds this only in the central portion 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 may also extend throughout the entire width dimension 21 of the at least one vacuum insulating panel 19. The connecting portion may be formed approximately strip-shaped.
    As can now be better seen in FIG. 2, the at least one vacuum insulation panel 19, spaced apart from one another in the direction of its longitudinal dimension 20, has a first end 26 and a second end 27. By formed in the extended or planar position of the two insulating layers 4, 5 longer than the longitudinal dimension 20 Ausnehmungslänge 23 of the recess 18, the two each in the direction of the longitudinal dimension 20 spaced from each other ends 26, 27 with respect to the outer insulating layer 4 in the wrapping direction in their relative Laae in the at least one Ausnehmuna 18 be adjustably received. This makes it possible that in the course of the wrapping process or the sheathing 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 the recess length 23 completely fills.
    It is also possible that at least one additional insulating element 28 is arranged or provided on at least one of the transverse end faces 16, 17 of the outer insulating layer 4. Preferably, the insulation elements 28 are provided on both of the transverse end faces 16, 17. The one or more insulating elements 28 serve also to be able to thermally insulate or seal the closure region of the wrapping unit 1 and in addition to be able to compensate for certain production inaccuracies. For this purpose, 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, the at least one insulating element 28 can be covered by the inner insulating layer 5 at least on its side facing away from the outer lining 6. For this purpose, a predetermined longitudinal extent of the inner insulating layer 5 of the straight longitudinal extent of the longitudinal end faces 14,15 plus the thickness of the at least one additional insulating element 28 is to be selected.
    Depending on the selected panel thickness 22, it may also be advantageous to be able to deform the vacuum insulating panel 19 from its initially planar, undeformed starting position into the insulating or insulating position, if this is facing the inner insulating layer 5 at least Side is provided with a plurality of spaced-apart in the direction of cover arranged notches 29. The notches 29 are indicated in dashed lines in FIG. 2 in the vacuum insulation panel 19. The notches 29 preferably have a parallel orientation with respect to the grooves 11 disposed in the outer insulating layer 4.
    The previously described outer lining 6 is preferably arranged on the outer surface 8 of the outer insulating layer 4. The closure device 7 can in turn be arranged or provided in the insulating or Isolierstelluna each other zuwendbaren or already turned ends of the outer lining 6, in particular its cladding element. As closure device 7, for example, interlocking, hook-shaped closure strips, a hook-and-loop fastener or the like could be selected.
    In Fig. 4, the wrapping unit 1 is shown simplified in a radial partial section, wherein the wrapping unit 1 is shown in the insulating or insulating position on the body or the memory 2 in its circumferentially closed position.
    Due to the tensile or the tensile stiffness and the pressure-resistant or pressure-resistant training of the outer lining 6 and also due to the outer insulating layer 4, which are arranged in the outer insulating layer 4 grooves 11 have been brought with their respective mutually facing groove surfaces 12 for mutual contact with each other. Therefore, the now closed grooves 11 are shown only with a simple stroke.
    Furthermore, it can be seen that the usually also zugsteif and pressure-resistant trained vacuum insulating panel 19 is arranged curved around the longitudinal axis 3.
