Abstract
Description
Die Erfindung betrifft einen plattenförmigen Formkörper zur Wärmeisolierung von Räumen, Behältern oder dergl. mit den im Oberbegriff des Anspruchs 1 angegebenen Merkmalen.The invention relates to a plate-shaped molded body for the thermal insulation of Rooms, containers or the like. With the specified in the preamble of claim 1 Characteristics.
Bei den Formkörpern dieser Art liegen die Profilschenkel und die zugehörigen Randbe reiche der Deckseiten bündig aneinander, so daß im Berührungsbereich der Profilschen kel mit den Deckseiten ein Wärmefluß aufgrund des unbehinderten Wärmeübergangs von der einen Fläche zu der anderen Fläche stattfindet. Der hierdurch bedingte Wärme verlust ist gegenüber dem relativ geringfügigen Wärmeverlust durch die Randverbindun gen erheblich. Um diese Unzuträglichkeit etwas auszugleichen, ist man gezwungen, die Wandstärke der Profile extrem gering zu halten, was wiederum eine aufwendige Querschnittsform der Profile erforderlich macht, um eine ausreichende Steifigkeit derselben gegen die durch das Vakuum im Inneren des Formkörpers bedingten äußeren Verformungskräften zu erzielen.In the molded bodies of this type, the profile legs and the associated edge are pass the deck sides flush with each other, so that in the contact area of the Profilschen kel with the deck sides a heat flow due to the unimpeded heat transfer from one surface to the other surface. The resulting heat loss is compared to the relatively minor heat loss due to the edge connection gene considerably. To compensate for this intolerance, one is forced to Keeping the wall thickness of the profiles extremely low, which in turn is an expensive process Cross-sectional shape of the profiles required to have sufficient rigidity the same against the external caused by the vacuum inside the molded body To achieve deformation forces.
Der Erfindung liegt die Aufgabe zugrunde, diese Mängel zu beseitigen oder zumindest zu verringern, und sie löst diese Aufgabe dadurch, daß zwischen die Profilschenkel und die anliegenden Randbereiche der Deckseiten jeweils ein dünnwandiger ringsumlaufen der Streifen aus wärmeisolierendem druckfestem Material eingefügt ist, der eine thermische Entkoppelung der beiden flächigen Teile bewirkt und damit auch die genann ten festigkeitsmäßigen Probleme durch die Wahl einer größeren Wandstärke und einfacher Profile, wie z. B. von U-Profilen, leichter beherrschbar macht.The invention has for its object to remedy these deficiencies or at least to reduce, and it solves this problem in that between the profile legs and the adjacent edge areas of the deck sides each run around a thin wall the strip of heat-insulating, pressure-resistant material is inserted, the one causes thermal decoupling of the two flat parts and thus also the genann ten strength problems by choosing a larger wall thickness and simple profiles, such as B. U-profiles, easier to control.
Gemäß der in dem Unteranspruch gekennzeichneten Ausführungsform bestehen die Streifen aus einem Geflecht von Glasfasern.According to the embodiment characterized in the dependent claim Strips of a network of glass fibers.
In der Zeichnung ist einer der Randbereiche des Gegenstandes der Erfindung in schema tischer Form im Schnitt dargestellt, und zwar In the drawing, one of the edge areas of the subject of the invention is in schematic table shape shown in section, namely
in Fig. 1 vor Zusammenfügen der einzelnen Teile in distanzierter Lage,in Fig. 1 prior to assembly of the individual parts in a distanced position,
in Fig. 2 nach erfolgtem Zusammenfügen der einzelnen Teile, Einbringen der Füllung, Herstellen der Randverbindungen und Evakuieren des Formkörpers.in Fig. 2 after the individual parts have been assembled, the filling has been introduced, the edge connections have been made and the molded body has been evacuated.
In beiden Figuren sind mit 1.1, 1.2 und 2 Teile der Umhüllung eines plattenförmigen Formkörpers aus dünnwandigem metallischen Material, im vorliegenden Ausführungs beispiel aus Edelstahlblech, bezeichnet.In both figures, 1.1 , 1.2 and 2 parts of the envelope of a plate-shaped molded body made of thin-walled metallic material, in the present embodiment example made of stainless steel sheet.
In Fig. 1 sind diese Teile der Deutlichkeit wegen distanziert voneinander dargestellt, wobei erkennbar ist, daß die beiden Deckbleche 1.1 und 1.2 eben ausgebildet sind, während das ringsumlaufende Seitenblech 2 im wesentlichen als U-Profil gestaltet ist, derart, daß seine Schenkel 2.1 und 2.2 parallel zu den Deckblechen 1.1 und 1.2 verlaufen und die Randkanten der Schenkel mit den Randkanten der Deckbleche fluch ten. Mit 3.1 und 3.2 sind zwei ringsumlaufende Streifen aus wärmeisolierendem Material, im vorliegenden Ausführungsbeispiel aus einem Geflecht von Glasfasern, bezeichnet, die zwischen die Schenkel 2.1, 2.2 des U-Profils 2 und die Randbereiche der Deckbleche 1.1, 1.2 zu liegen kommen.In Fig. 1 these parts are shown distanced from each other for the sake of clarity, it being apparent that the two cover plates 1.1 and 1.2 are flat, while the circumferential side plate 2 is essentially designed as a U-profile, such that its legs 2.1 and 2.2 run parallel to the cover plates 1.1 and 1.2 and the edge edges of the legs are aligned with the edge edges of the cover plates. With 3.1 and 3.2 , two circumferential strips of heat-insulating material, in the present exemplary embodiment made of a mesh of glass fibers, are referred to, which are between the legs 2.1 , 2.2 of the U-profile 2 and the edge areas of the cover plates 1.1 , 1.2 come to rest.
Die Streifen 3.1, 3.2 sind so bemessen, daß sie der Länge der parallel verlaufenden Abschnitte zwischen U-Profil und Deckblechen entsprechen. In Fig. 2 sind die Teile nach Fig. 1 in zusammengefügtem Zustand dargestellt, wobei der Spaltraum zwischen Deckblechen und Streifen einerseits und Streifen und U-Profilschenkel andererseits geschlossen und die Randkanten der Deckbleche und Profilschenkel miteinander bei 4.1, 4.2 vakuumdicht verbunden, im vorliegenden Fall verschweißt, sind. Aus Fig. 2 ist ferner ersichtlich, daß nach Einbringen einer aus druckfestem porösem Wärmedämm stoff, im vorliegenden Ausführungsbeispiel aus verpreßten Mikroglasfasern bestehende Füllung 5 in den Formkörper und nach Evakuieren desselben über einen (nicht darge stellten) Evakuierungsstutzen die Streifen durch den äußeren Luftdruck zwischen die beiden sie begrenzenden Blechteile unverschieblich eingeklemmt werden, so daß eigene Befestigungsmittel für diese entbehrlich sind.The strips 3.1 , 3.2 are dimensioned so that they correspond to the length of the parallel sections between the U-profile and cover plates. In Fig. 2, the parts of Fig. 1 are shown in the assembled state, the gap between cover plates and strips on the one hand and strips and U-profile legs closed on the other and the edge edges of the cover plates and profile legs connected to each other at 4.1, 4.2 vacuum-tight, in the present case are welded. From Fig. 2 it can also be seen that after introducing a pressure-resistant porous thermal insulation material, in the present embodiment from compressed microglass fibers, filling 5 into the molded body and after evacuating the same via an (not shown) evacuation nozzle, the strips by the external air pressure between the two sheet metal parts delimiting them are clamped so that they cannot be fastened in their own way.
