Description

Die Erfindung betrifft ein wärmeisolierendes Gehäuse zur Lagerung von Kühlgut mit einer wärmeisolierenden Tür und Vakuum-lsolationspaneele, welche in eine Diffusionsschutzfolie eingesiegelte Stützkörper aufweisen und welche zumindest weitestgehend in ein durch Aufschäumen erzeugtes Wärmeisolationsmaterial des Gehäuses und/oder der Tür eingebettet sind.The invention relates to a heat-insulating housing for storing refrigerated goods a heat-insulating door and vacuum insulation panels, which are wrapped in a diffusion protection film have sealed support body and which at least largely in a thermal insulation material of the housing produced by foaming and / or the door are embedded.

Bei Kältegeräten wie beispielsweise Kühlschränken, Gefriergeräten oder dergleichen ist man zur Verbesserung ihrer Wärmeisolationseigenschaften und somit zur Senkung ihres Energieverbrauchs dazu übergegangen, in das durch Aufschäumen erzeugte herkömmliche Wärmeisolationsmaterial sogenannte Vakuum-lsolationspaneele einzubringen. Diese umfassen in eine Diffusionsschutzfolie eingebrachte evakuierbare, als Stützkörper dienende Materialien wie beispielsweise zu Formkörpern gepreßte Aerogele, Kieselsäure oder Glasfasern, bzw. aus offenzelligen organischen Polymerschäumen wie Polyurethanschaum, Polyisocyanuratschaum oder Polystyrolschaum gebildete Plattenkörper. Bei der Auswahl der Vakuum-lsolationspaneele für den Einsatz bei in großen Stückzahlen hergestellten Kältegeräten ist man bestrebt, für die zur Anwendung kommenden Vakuum-lsolationspaneele einen Kompromiß zwischen deren Kosten einerseits sowie deren Wärmeleitfähigkeit bzw. deren Gewicht andererseits zu finden. Als besonders günstig im Hinblick auf diesen Kompromiß haben sich Vakuum-lsolationspaneele mit Stützkörpern auf der Basis von offenzelligen organischen Polymerschäumen herauskristallisiert, wobei in diesem Rahmen Stützkörper aus offenzelligem Polystyrolschaum eine führende Rolle einnehmen. Bei den aus offenzelligen organischem Polymerschäumen, insbesondere bei den aus Polystyrolschäumen gebildeten Stützkörpern besteht jedoch die Gefahr, daß diese aufgrund der exothermen Reaktion des in flüssigen Ausgangskomponenten eingebrachten herkömmlichen Wärmeisolationsmaterials entstehenden Wärme einerseits und den beim Aufschäumen des Wärmeisolationsmaterials entstehenden Druck andererseits beschädigt werden und somit ihre an sich hervorragenden Wärmedämmeigenschaften zumindest zum Teil einbüßen.In refrigeration devices such as refrigerators, freezers or the like is one to improve their thermal insulation properties and thus to Lowering their energy consumption has shifted to that by foaming produced conventional thermal insulation material so-called vacuum insulation panels bring in. These include a diffusion protection film evacuable materials serving as support bodies, such as for example Molded bodies pressed aerogels, silica or glass fibers, or from open cells organic polymer foams such as polyurethane foam, polyisocyanurate foam or polystyrene foam formed plate body. When choosing the vacuum insulation panels for use in large quantities Refrigeration devices are endeavored for the vacuum insulation panels used a compromise between their costs on the one hand and their thermal conductivity or to find their weight on the other hand. As particularly cheap in view of this compromise have vacuum insulation panels with support bodies crystallized out on the basis of open-celled organic polymer foams, in this frame support body made of open-cell polystyrene foam take a leading role. In the case of open-celled organic polymer foams, especially in the case of the support bodies formed from polystyrene foams however, there is a risk that due to the exothermic reaction of the in liquid starting components introduced conventional thermal insulation material generated heat on the one hand and the foaming of the heat insulation material resulting pressure can be damaged on the other hand and hence their excellent thermal insulation properties, at least in part lose.

Der Erfindung liegt die Aufgabe zugrunde, Maßnahmen vorzuschlagen, durch welche bei Gehäusen gemäß dem Oberbegriff des Anspruches 1 unter Anwendung von mit exothermer Reaktion aushärtendem Wärmeisolationsmaterial der Einsatz von Vakuum-lsolationspaneele mit aus offenzelligen organischen Polymerschäumen gebildeten Stützkörpern unter Beibehaltung ihrer wärmeisolierenden Eigenschaften möglich ist.The invention has for its object to propose measures by which for housings according to the preamble of claim 1 using of heat-insulating material that cures with an exothermic reaction vacuum insulation panels with open-cell organic polymer foams formed support bodies while maintaining their heat insulating properties is possible.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß die Vakuum-lsolationspaneele zumindest weitestgehend auf ihren dem Wärmeisolationsmaterial zugewandten Flächen mit Mitteln versehen sind, durch welche die beim Aushärten des Wärmeisolationsmaterials entstehende Wärme von den Vakuum-lsolationspaneelen zumindest weitestgehend abgehalten ist.This object is achieved according to the invention in that the vacuum insulation panels at least as far as possible on their facing the heat insulation material Surfaces are provided with means by which the Heat insulation material generates heat from the vacuum insulation panels is at least largely prevented.

Durch die erfindungsgemäße Maßnahme ist die Möglichkeit eröffnet, nicht nur Vakuum-lsolationspaneele verwenden zu können, deren Stützmaterialien aufgrund ihrer Werkstoffbeschaffenheit per se geeignet sind, die bei der exothermen Reaktion des Ausschäumprozesses freiwerdende Wärme unbeschadet hinzunehmen, sondern nunmehr auch Materialien für Stützkörper in Betracht kommen können, welche an sich durch die freiwerdende Wärme des Ausschäumprozesses Schaden nehmen würden, jedoch hinsichtlich ihres Eigengewichtes, ihrer Kosten und auch bezüglich ihrer geringen Wärmeleitfähigkeit deutliche Vorzüge gegenüber den erstgenannten besitzen und daher besonders für die Großserienproduktion von Gehäusen bei Haushaltskältegeräten geeignet sind. Somit können nunmehr Vakuumisolations-Isolationspaneele mit Stützkörpern aus offenzelligen organischen Polymerschäumen, insbesondere Polystyrolschäumen zum Einsatz kommen.The measure according to the invention opens up the possibility of not only vacuum insulation panels to be able to use their support materials due to their Material properties per se are suitable for the exothermic reaction to accept the heat released during the foaming process undamaged, but materials for support bodies can now also be considered, which damage itself due to the heat released during the foaming process would, however, with regard to their own weight, their costs and also with regard to Their low thermal conductivity has clear advantages over the former own and therefore especially for the large-scale production of housings Household refrigerators are suitable. Vacuum insulation panels can now be used with support bodies made of open-celled organic polymer foams, especially polystyrene foams are used.

Unter Einsiegeln ist das vakuumdichte Verschließen der Diffusionsschutzfolie nach dem Evakuiervorgang des in die haubenartige Diffusionsschutzfolie eingelegten Stützkörpers und des von der Diffusionsschutzfolie umgrenzten Raumes zu verstehen. Sealing is the vacuum-tight sealing of the diffusion protection film after the evacuation process of the inserted in the hood-like diffusion protection film Support body and the space delimited by the diffusion protection film understand.

Nach einer bevorzugten Ausführungsform des Gegenstandes der Erfindung ist vorgesehen, daß die Mittel ein Wärmemenge-Aufnahmevermögen besitzen, welches die beim Aushärten des Wärmeisolationsmaterials entstehende Wärme zumindest weitestgehend aufzunehmen und somit von den Vakuum-lsolationspaneelen abzuhalten vermag.According to a preferred embodiment of the subject matter of the invention, that the agents have a heat absorption capacity, which the heat generated when the thermal insulation material hardens at least as far as possible and thus to keep them away from the vacuum insulation panels can

Durch den Einsatz derartiger Materialien ist mit besonders geringem fertigungstechnischem Aufwand ein ausreichender Schutz der Vakuum-lsolationspaneele, insbesondere für deren Stützkörper, gegen die beim Ausschäumprozess entstehende Wärme bereitgestellt.Through the use of such materials, the manufacturing technology is particularly low Sufficient protection of the vacuum insulation panels, especially for their supporting bodies, against those arising during the foaming process Heat provided.

Gemäß einer nächsten bevorzugten Ausführungsform des Gegenstandes der Erfindung ist vorgesehen, daß die Mittel als nichtmetallische, platinenartige Werkstoffe ausgebildet sind, deren spezifische Wärmekapazität cp im Bereich zwischen 1 und 2,5 kJ/kg K liegt und deren Wärmeleitfähigkeit λ zwischen 0,04 und 0,40 W/(m·K) beträgt.According to a next preferred embodiment of the object of the invention it is provided that the means are designed as non-metallic, board-like materials, the specific heat capacity c p is in the range between 1 and 2.5 kJ / kg K and the thermal conductivity λ between 0.04 and 0.40 W / (m · K).

Unter platinenartigen Werkstoffen sind Werkstoffplatten mit dünner Materialstärke zu verstehen.Among plate-like materials are material plates with a thin material thickness to understand.

Durch die Verwendung derartiger Werkstoffe, unter welche z.B. ein High Impact Polystyrol, Polyolifine, Polyethylenterephthalate, und Polybutylenterephtalate, Polyamide und weitere teilkristalline sowie amorphe thermoplastische Polymere mit einer Glasübergangstemperatur im Bereich von oder mehr als 100 °C fallen, lassen sich die Vakuum-lsolationspaneele bzw. deren Stützkörper auf besonders einfache aber dennoch wirkungsvolle Weise schützen, da sich die Schutzmaßnahme durch die platinenartige Ausführung besonders einfach und positionsgenau an den dem aufschäumenden Wärmeisolationsmaterial zugewandten Flächen der Vakuum-Isolationspaneele positionieren läßt und sich zugleich eine hohe Dämmwirkung bei einem geringen, durch die Schutzmaßnahmen hervorgerufenen Gewichtszuwachs, ergibt.By using such materials, among which e.g. a high impact Polystyrene, polyolifins, polyethylene terephthalates, and polybutylene terephthalates, Polyamides and other partially crystalline and amorphous thermoplastic polymers with a glass transition temperature in the range of or more than 100 ° C the vacuum insulation panels or their supporting bodies are particularly simple but still protect effectively because the protective measure the board-like design is particularly simple and precisely positioned on the Foaming heat insulation material facing surfaces of the vacuum insulation panels can be positioned and at the same time a high insulation effect a small weight gain caused by the protective measures, results.

Ähnlich gute Wärmedämmeigenschaften, wie bei beiden nichtmetallischen Werkstoffen bei gleichzeitig einfacher und dennoch wirkungsvoller Abschirmung gegen die freiwerdende Wärme der exothermen Reaktion des Aufschäumprozesses lassen sich erzielen, wenn nach einer alternativen Ausführungsform des Gegenstandes der Erfindung vorgesehen ist, daß die Mittel als platinenartige metallische Werkstoffe ausgebildet sind, deren spezifische Wärmekapazität cp 0,4 bis 1,0 kJ (kgK) beträgt und deren Wärmeleitfähigkeit λ zwischen 0,15 und 220 W/(m·K) beträgt.Similar good thermal insulation properties, as with both non-metallic materials with at the same time simple and yet effective shielding against the heat released from the exothermic reaction of the foaming process, can be achieved if, according to an alternative embodiment of the object of the invention, it is provided that the agents are designed as sheet-like metallic materials , whose specific heat capacity c p is 0.4 to 1.0 kJ (kgK) and whose thermal conductivity λ is between 0.15 and 220 W / (m · K).

Entsprechend einer weiteren bevorzugten Ausführungsform des Gegenstandes der Erfindung ist vorgesehen, daß die platinenartigen Werkstoffe am Vakuum-lsolationspaneel mit die Wärmeleitung zumindest weitestgehend unterbindenden Klebemitteln festgesetzt sind.According to a further preferred embodiment of the subject of The invention provides that the board-like materials on the vacuum insulation panel with at least largely preventing the heat conduction are fixed.

Besonders kostengünstig in der Herstellung sind durch Festkörperplatinen geschützte Vakuumisolationspaneele, wenn nach einer alternativen Ausführungsform des Gegenstandes der Erfindung vorgesehen ist, daß die platinenartigen Werksteoffe am Stützkörer angeordnet und in die Diffusionsschutzfolie eingesiegelt sind.Solid state boards are particularly inexpensive to manufacture protected vacuum insulation panels, if according to an alternative embodiment the object of the invention is provided that the board-like Materials arranged on the support body and sealed in the diffusion protection film are.

Besonders sicher und rasch sowie kostengünstig geschützt ist der Stützkörper von der aufgrund der exothermen Reaktion der Wärmeisolationsmaterials freiwerdenden Wäreme, wenn nach einer anderen alternativen Ausführungsform des Gegenstandes der Erfindung vorgesehen ist, daß die Mittel als Folie ausgebildet sind, welche den Stützkörper zumindest an seinen dem Wärmeisolationsmaterial zugewandten Flächen bedeckt und daß der mit der Folie bedeckte Stützkörper in die Diffusionsschutzfolie eingesiegelt ist.The support body from is particularly safe and quick and inexpensive to protect due to the exothermic reaction of the thermal insulation material released heat if according to another alternative embodiment the object of the invention is provided that the means as a film are formed, which the support body at least on its Areas covered with heat insulation material and covered with the film covered support body is sealed in the diffusion protection film.

Als Folienwerkstoffe kommen hier z. B. Kunststoffe mit hoher spez. Wärmekapazität wie Polyäthyln 2,5 KJ/(kg·K) in Betracht.Here come as film materials such. B. plastics with high spec. Heat capacity like polyethylene 2.5 KJ / (kg · K) into consideration.

Hiermit ist nicht nur eine kostengünstige und somit in der Großserie prozeßsicher durchzuführende Befestigungsmaßnahme der platinenartigen Werkstoffe am Vakuum-lsolationspaneel bereitgestellt, sondern zugleich auch der Wärmeleitfähigkeit, insbesondere der der metallischen Werkstoffe, entgegengewirkt.This is not only an inexpensive and therefore process reliable in large series Fastening measure to be carried out on the board-like materials on the vacuum insulation panel provided, but also the thermal conductivity, counteracted in particular that of metallic materials.

Auf besonders einfache und wirkungsvolle Weise mit wenigen Handgriffen geschützt sind die allseitig innerhalb des Wärmeisolationsmaterials angeordneten Vakuum-lsolationspaneele, wenn nach einer weiteren bevorzugten Ausführungsform des Gegenstandes der Erfindung vorgesehen ist, daß die platinenartigen Werkstoffe in Art einer Schutzhaube ausgebildet und über das Vakuum-lsolationspaneel gestülpt sind.Protected in a particularly simple and effective manner with just a few hand movements are the vacuum insulation panels arranged on all sides within the thermal insulation material, if according to a further preferred embodiment the object of the invention is provided that the board-like materials designed in the manner of a protective hood and over the vacuum insulation panel are put up.

Besonders unempfindlich bezüglich ihrer Handhabung im Fertigungsdurchlauf sind die nichtmetallischen platinenartigen Werkstoffe, wenn nach einer nächsten vorteilhaften Ausgestaltung des Gegenstandes der Erfindung vorgesehen ist, daß die nichtmetallischen platinenartigen Werkstoffe aus vernetzten Festkörperplatinen gebildet sind.Are particularly insensitive to their handling in the production run the non-metallic board-like materials, if after a next advantageous Embodiment of the object of the invention is provided that the non-metallic board-like materials formed from cross-linked solid-state boards are.

Mit besonders geringen Gewicht sind die nichtmetallischen platinenartigen Werkstoffe beaufschlagt, wenn nach einer alternativen Ausführungsform des Gegenstandes der Erfindung vorgesehen ist, daß die nichtmetallischen platinenartigen Werkstoffe aus schäumbarem Material gebildet sind, welches im aufgeschäumten Zustand eine geschlossenporige Struktur aufweist.The non-metallic board-like materials are particularly light acted upon if according to an alternative embodiment of the object the invention provides that the non-metallic board-like Materials are formed from foamable material, which in the foamed Condition has a closed-pore structure.

Entsprechend einer anderen Ausführungsform des Gegenstandes der Erfindung ist vorgesehen, daß die Vakuum-lsolationspaneele zumindest auf ihrem dem Wärmeisolationsmaterial zugewandten Flächen mit einem Überzug aus gefrorenem Isocyanat ausgestattet sind.According to another embodiment of the subject of the invention provided that the vacuum insulation panels at least on their the thermal insulation material facing surfaces with a coating of frozen Isocyanate are equipped.

Durch die exotherme Reaktion des Aufschäumens schmilzt das im gefrorenen Zustand an den Vakuum-lsolationspaneelen vorgesehene Isocyanat, wodurch die beim Aufschäumen entstehende Wärme abgebaut wird und somit verhindert ist, daß das Vakuum-lsolationspaneel Temperatureinflüssen ausgesetzt ist, welche eine schädigende Wirkung an diesem herrufen könnten. Bei der Anwendung von gefrorenem Isocyanat wird für die in flüssigen Ausgangskomponenten für das Wärmeisolationsmaterial zur Anwendung kommende Polyolformulierung dahingehend modifiziert, daß der Isocyanatanteil des Wärmeisolationsmaterials um die bereits den Vakuum-lsolationspaneelen anhaftenden Menge vermindert ist. Das schmelzende Isocyanat der Vakuum-lsolationspaneele verbindet sich mit der modifizierten Polyolformulierung des Wärmeisolationsmaterials, so daß bei entsprechender Dimensionierung eine rückstandsfreie Vermischung der beiden Komponenten sichergestellt ist. Due to the exothermic reaction of foaming, it melts in the frozen state Isocyanate provided on the vacuum insulation panels, whereby the heat generated during foaming is reduced and is thus prevented, that the vacuum insulation panel is exposed to temperature influences which could have a damaging effect on it. When using frozen isocyanate is used in the liquid starting components for the In this regard, heat insulation material polyol formulation used modified that the isocyanate portion of the heat insulation material to the already the amount adhering to the vacuum insulation panels is reduced. The melting isocyanate of the vacuum insulation panels combines with the modified Polyol formulation of the heat insulation material, so that with appropriate Dimensioning a residue-free mixing of the two components is ensured.

Entsprechend einer anderen alternativen Ausführungsform des Gegenstandes der Erfindung ist vorgesehen, daß die Energie des Phononensystems der Vakuum-lsolationspaneele erniedrigt ist.According to another alternative embodiment of the subject of Invention is provided that the energy of the phonon system of the vacuum insulation panels is lowered.

Durch eine solche Maßnahme ist bewirkt, daß die per se gegen die exotherme Reaktionswärme des Aufschäumens empfindlichen Stützkörpermaterialien eine größere Wärmemenge durch die Erhöhung der Temperaturdifferenz zwischen den Vakuum-lsolationspaneelen und der Abwärme des Aufschäumens aufzunehmen vermögen, ohne daß diese Abwärme Zustandsveränderungen oder Zerstörungen an den Stützkörpermaterialien hervorrufen könnte. Darüber hinaus kann wie bei den mit gefrorenem Isocyanat überzogenen Vakuum-lsolationspaneelen ein unter Umständen den zügigen Fertigungsablauf der wärmeisolierenden Gehäuse hemmender Fertigungszwischenschritt, nämlich die Anbringung der metallischen oder nichtmetallischen platinenartigen Wärmeschutzmaßnahmen, entfallen.Such a measure has the effect that per se against the exothermic heat of reaction foaming sensitive support body materials a larger Amount of heat by increasing the temperature difference between the vacuum insulation panels and can absorb the waste heat from the foaming, without this waste heat causing changes in state or destruction could cause the support body materials. In addition, as with the under certain circumstances with vacuum insulation panels coated with frozen isocyanate the rapid manufacturing process of the heat-insulating housing Intermediate manufacturing step, namely the attachment of the metallic or non-metallic circuit board-like heat protection measures are not required.

Dieser ist von einer durch spanlose Formgebung einer Kunststoffplatine gebildeten Innenverkleidung 12 ausgekleidet, welche an ihrer Rückseite, auf deren vom Kühlraum 11 abgewandten Außenseite mit einem in wärmeleitendem Kontakt mit der Rückseite stehenden Verdampfer 13 versehen ist. Im Abstand zur Innenverkleidung 12 weist das wärmeisolierende Gehäuse 10 eine Außenverkleidung 14 auf, welche wie üblich (jedoch hier nicht im einzelnen dargestellt) aus mehreren Abschnitten zusammengesetzt ist, wovon der ihre Rückwand 15 bildende Abschnitt aus einem aluminiumkaschierten Pappkarton, die ihre Seitenwände 16 bildende Abschnitte aus spanlos geformten Stahlblechplatinen und die ihre Decke 17 bzw. ihrem Boden 18 bildende Abschnitte aus Kunststoff gebildet sind. Zwischen der Außenverkleidung 14 und der Innenverkleidung 12 ist ein im flüssigen Ausgangskomponenten eingebrachtes Wärmeisolationsmaterial 19 wie beispielsweise Polyurethanschaum vorgesehen, welcher durch seine adhäsive Wirkung die Innenverkleidung 12 und die Außenverkleidung 14 zu einem formsteifen Gebilde verbindet und welcher unter einer exothermen Reaktion aufschäumt und aushärtet. Das wärmeisolierende Gehäuse 12 ist auf seiner der Rückwand 15 gegenüberliegenden Seite mit einer verschwenkbar gelagerten wärmeisolierenden Tür 20 versehen, über welche der Kühlraum 11 zugänglich ist. Die Tür 20 weist eine aus Stahlblech geformte Außenverkleidung 21 und eine dazu beabstandete, spanlos geformte Kunststoffinnenverkleidung 22 auf, welche mit der Außenverkleidung 21 durch das Wärmeisolationsmaterial 19 zu einem formsteifen Gebilde verbunden ist.1 and 2 is a simplified schematic representation for use heat-insulating housing suitable for a household refrigerator 10, in which a cooling space 11 is arranged. This is from one inner cladding 12 formed by chipless shaping of a plastic board lined, which on its back, facing away from the cold room 11 Outside with a thermally conductive contact with the back Evaporator 13 is provided. At a distance from the inner lining 12, the heat insulating Housing 10 on an outer panel 14, which as usual (however not shown in detail here) composed of several sections is, of which the portion forming its rear wall 15 is made of an aluminum-clad Cardboard, the 16 sidewalls formed from non-cutting formed sheet steel blanks and the 18 forming their ceiling 17 or their bottom Sections are made of plastic. Between the outer panel 14 and the Inner lining 12 is an introduced in the liquid starting components Thermal insulation material 19 such as polyurethane foam is provided, which by its adhesive effect the inner lining 12 and the outer lining 14 connects to a dimensionally stable structure and which under an exothermic Reaction foams and hardens. The heat insulating housing 12 is on its side opposite the rear wall 15 with a pivotable stored heat-insulating door 20, through which the cold room 11 accessible is. The door 20 has an outer panel 21 formed from sheet steel and a spaced-apart, non-cutting plastic inner lining 22, which with the outer panel 21 through the heat insulation material 19 into one dimensionally stable structure is connected.

Wie insbesondere aus den Figuren 2 und 3 ersichtlich ist, ist sowohl das wärmeisolierende Gehäuse 10 in seinen beiden Seitenwänden und an seiner Rückwand als auch die Tür 20 mit innerhalb des Wärmisolationsmaterials 19 angeordneten Vakuum-lsolationspaneelen ausgestattet, von denen das innerhalb der jeweiligen Gehäuseseitenwand sowie das innerhalb der Tür 20 vorgesehene Vakuum-Isolationspaneel 23 jeweils gleichartig aufgebaut ist. Die Vakuum-lsolationspaneele 23, welche zumindest annähernd über die Höhe und Breite der Tür 20 und der Seitenwände des Gehäuses 10 angeordnet sind, umfassen einen beispielsweise aus offenzelligen organischen Polymerschaum, wie z.B. Polystyrolschaum, gefertigten quaderförmigen Stützkern 24, welcher in eine diffusionsdichte, beispielsweise mit Aluminium kaschierte Schutztasche 25 eingelegt ist, welche nach einem Evakuiervorgang vakuumdicht verschlossen ist. Im vorliegenden Ausführungsbeispiel ist eine der großflächigen Außenseiten der Vakuum-lsolationspaneele 23 mit einem aus platinenartigen Werkstoff gefertigten Schutzkörper 26 aus nichtmetallischem Werkstoff, wie beispielsweise High Impact Polystyrol, Polyethylenterephtalat, Polybutylenterephtalat oder Polyamid versehen, wobei der platinenartige, die ihm zugewandten Außenfläche der Schutztasche 25 überdeckende Schutzkörper an der Schutztasche 25 mit einem die Wärmeleitung zumindest weitestgehend unterbindenden Kleber festgesetzt ist. Die dem Schutzkörper 26 gegenüberliegende großflächige Außenseite der Schutztasche 25 dient der Befestigung des Vakuum-lsolationspaneels 23 an den Seitenwänden 16 bzw. an der Außenverkleidung 21, wobei das Vakuum-Isolationspaneel 23 im Befestigungszustand zumindest weitestgehend die Fläche der Seitenwände 16 bzw. der Außenverkleidung 21 abdeckt.As can be seen in particular from Figures 2 and 3, is both the heat insulating Housing 10 in its two side walls and on its rear wall as also the door 20 with vacuum insulation panels arranged inside the heat insulation material 19 equipped, of which within the respective housing side wall and the vacuum insulation panel provided inside the door 20 23 is constructed in the same way. The vacuum insulation panels 23, which is at least approximately the height and width of the door 20 and the side walls of the housing 10 are arranged, for example, comprise an open-cell one organic polymer foam, e.g. Polystyrene foam, manufactured cuboid support core 24, which in a diffusion-tight, for example with Aluminum-coated protective bag 25 is inserted, which after an evacuation is sealed vacuum-tight. In the present embodiment one of the large-area outer sides of the vacuum insulation panels 23 with one made of board-like material protective body 26 made of non-metallic Material such as high impact polystyrene, polyethylene terephthalate, polybutylene terephthalate or polyamide provided, the board-like, the facing him Outer surface of the protective bag 25 covering protective body on the Protective bag 25 with an at least largely preventing heat conduction Glue is fixed. The large area opposite the protective body 26 The outside of the protective bag 25 is used to attach the vacuum insulation panel 23 on the side walls 16 and on the outer panel 21, respectively the vacuum insulation panel 23 at least largely in the attached state covers the surface of the side walls 16 or the outer lining 21.

Ein zu dem Vakuum-Isolationspaneel 23 ähnliches Vakuum-lsolationspaneel 27 ist an der den Verdampfer 13 beinhaltenden Rückwand des Gehäuses 10 vorgesehen. Das Vakuum-lsolationspaneel 27 weist wie das Vakuum-Isolationspaneel 23 einen aus offenzelligen Polystyrolschaum gefertigten Stützkern 28 auf, welcher allseitig von einer Schutztasche 29 umgeben und von dieser nach dem Evakuiervorgang vakuumdicht umschlossen ist. In Abweichung von dem Vakuum-Isolationspaneel 23 weist das im wesentlichen hinsichtlich seiner Kontur an die Kontur der Rückwand des Gehäuses 10 angepaßte Vakuum-lsolationspaneel 27 an seinen beiden großflächigen Außenseiten jeweils einen die Fläche der Außenseite überdeckenden Schutzkörper 30 auf, welcher wie der Schutzkörper 26 dazu dient, die durch die exotherme Reaktion beim Ausschäumen des Wärmeisolationsmaterials 19 frei werdende Wärme von dem Vakuum-lsolationspaneel 27 abzudämmen und welcher anhand eines die Wärmeleitung verhindernden Klebstoffes jeweils an der Außenseite der Schutztasche 29 festgesetzt ist. A vacuum insulation panel 27 similar to the vacuum insulation panel 23 is provided on the rear wall of the housing 10 containing the evaporator 13. The vacuum insulation panel 27, like the vacuum insulation panel 23, has one Support core 28 made of open-cell polystyrene foam, which on all sides surrounded by a protective bag 29 and this after the evacuation is enclosed in a vacuum-tight manner. Deviating from the vacuum insulation panel 23 indicates this essentially with regard to its contour to the contour of the rear wall of the housing 10 adapted vacuum insulation panel 27 on its two large surfaces Outside each cover the surface of the outside Protective body 30, which, like the protective body 26, is used by the exothermic reaction when foaming the heat insulation material 19 liberated To isolate heat from the vacuum insulation panel 27 and which on the outside using an adhesive that prevents heat conduction the protective bag 29 is fixed.

Wie insbesondere aus Fig. 3 hervorgeht, ist das Vakuum-lsolationspaneel 27 nicht mit einer seiner großflächigen Außenseiten an der Innenverkleidung 12 oder an der Außenverkleidung 14 festgesetzt, sondern annähernd mittig zwischen den beiden positioniert, und somit allseitigen in das Wärmeisolationsmaterial 19 eingebettet.As can be seen in particular from FIG. 3, the vacuum insulation panel 27 is not with one of its large outer sides on the inner panel 12 or on the Outer cladding 14 fixed, but approximately in the middle between the two positioned, and thus embedded on all sides in the heat insulation material 19.
