Speicherbehälter für WärmespeichermassenStorage tank for heat storage mass
Die Erfindung betrifft einen Speicherbehälter für Wärmespeichermassen nach dem Oberbegriff des Patentanspruches.The invention relates to a storage container for heat storage masses according to the preamble of the patent claim.
Speicherbehälter dieser Art sind beispielsweise in der DE-OS 28 02 343 beschrieben und dargestellt. Als Speichermassen dienen Latentsalze, die während des Phasenwechsels ihr Volumen stark ändern.Storage containers of this type are described and shown, for example, in DE-OS 28 02 343. As storage masses serve latent salts, which change their volume strongly during the phase change.
Sehr starke Wände der Speicherbehälter halten den Volumenveränderungen stand. Sie verschlechtern jedoch den Wärmedurchgang. Weniger starke Wände sind hingegen starken Biegebeanspruchungen ausgesetzt, sofern sie aus formstabilem Material bestehen. Wände aus flexiblem Material wie Gummi geben den Volumenveränderungen nach, so daß hier keine übermäßige Beanspruchung auftritt. Speicherbehälter aus diesem Material bestehen vorzugsweise aus flachen Kissen, die durch flächige Elemente stabilisiert werden müssen.Very thick walls of the storage tanks keep the volume changes was standing. However, they worsen the heat transfer. Less strong walls, on the other hand, are subject to strong bending loads exposed, provided they are made of dimensionally stable material. Walls made of flexible material such as rubber give the Volume changes after, so that no excessive stress occurs here. Storage containers made from this material preferably consist of flat cushions, which have to be stabilized by flat elements.
Für die Zuordnung vieler Speicherelemente in einem System ist es angebracht, die Speicherbehälter aus einem Material mit einer ausreichenden Eigenstabilität zu fertigen. Die Speicherelemente können so unter Zwischenfügen von Stützkörpern übereinander gestapelt werden. Die entstehenden Zwischenräume dienen dem Vorbeileiten eines Wärmeträgers.For the allocation of many storage elements in a system, it is advisable to make the storage container from one material with a to produce sufficient inherent stability. The storage elements can thus with the interposition of supporting bodies on top of one another be stacked. The resulting gaps serve to guide a heat transfer medium past.
Die Wandflächen eines Speicherbehälters sollen so gestaltet sein, daß sie sich trotz einer ausreichenden Eigenstabilität bei einer auftretenden Volumenveränderung der Speichermasse ohne negative Folgen für das Wandmaterial bewegen können.The wall surfaces of a storage container should be designed in this way be that, despite sufficient inherent stability, when there is a change in volume of the storage mass can move without negative consequences for the wall material.

Gemäß der Erfindung geschieht dieses durch die im Kennzeichen des Patentanspruches 1 beschriebene Gestaltung der Wandflächen. According to the invention, this is done by the design of the wall surfaces described in the characterizing part of claim 1.
Konzentrisch gewellte Wandflächen, wie sie beispielsweise bei Barometer-Druckdosen mit Erfolg eingesetzt werden, haben die Fähigkeit, Lageveränderungen ohne starke Spannungen innerhalb des Wandmaterials vorzunehmen. Sie eignen sich deshalb gut für Wandflächen von Speicherbehältern, da sie eine ausreichende Eigenstabilität mit einer hohen Beweglichkeit verbinden. Die Wandflächen können aus den gebräuchlichen Werkstoffen Kunststoff oder Stahl bestehen.Concentrically corrugated wall surfaces, such as those used with success in barometer pressure cans, have the Ability to change position without strong tension within the wall material. They are therefore suitable good for wall surfaces of storage containers, as they combine sufficient inherent stability with high mobility. The wall surfaces can consist of the usual materials plastic or steel.
Die Wandflächen können in einer Ebene liegen. Sie bestehen dann aus durchgehend mit konzentrischen Wellen versehenen Scheiben. Auch andere Konturen der Wandfläche sind möglich. Sehr zweckmäßig ist beispielsweise eine kegelförmige Gestaltung der Wandflachen. Es entstehen dann flache tellerförmige Speicherkörper, die sich sehr einfach mit geringem Abstand übereinander stapeln lassen. Eine zentrale Aussparung ermöglicht das Vorbeiströmen eines Wärmeträgers an der unteren Kegelfläche und dessen Hochsteigen zum nächsten Element.The wall surfaces can lie in one plane. They then consist of consistently provided with concentric waves Discs. Other contours of the wall surface are also possible. A conical design, for example, is very useful of the wall surfaces. Flat plate-shaped storage bodies are then created, which are very easily spaced apart stack on top of each other. A central recess allows a heat transfer medium to flow past the lower one Conical surface and its ascent to the next element.

Der Speicherbehälter zur Aufnahme einer Latentspeichermasse besteht aus Wandflächen 2, die konzentrisch angeordnete Wellen 3 besitzen. Diese Wellen 3 machen die Wandflächen 2 trotz ihrer Eigenstabilität sehr flexibel, wodurch Volumenveränderungen der Speichermasse 1 ausgeglichen v/erden. Es können beliebig viele Speicherbehälter im Abstand übereinander angeordnet werden, um einen Großspeicher zu erzeugen. Speicherbehälter mit konischen Wandflächen besitzen dabei zentrische Strömungsöffnungen 4.The storage container for receiving a latent storage mass consists of wall surfaces 2, which are concentrically arranged Own waves 3. These waves 3 make the wall surfaces 2 very flexible despite its inherent stability, whereby changes in volume of the storage mass 1 are balanced out. It Any number of storage tanks can be arranged one above the other at a distance to create a large storage tank. Storage tanks with conical wall surfaces have central flow openings 4.
