Description

Die Erfindung betrifft eine Platte mit veränderlichem Wärmedurchgang, z. B. Bauplatte zur Begrenzung von Räumen, die mindestens einen hermeüsch abgedichteten Hohlraum aufweist.The invention relates to a plate with variable heat transfer, e.g. B. Building board to limit Spaces that have at least one hermetically sealed cavity.

Es ist eine Wärmeleitplatte bekannt, welche die Wärme schnell mittels eines verdampfenden Wärmeträgermediums von einer Seite zur anderen leitet. Bei dieser Platte kann die Wärmeleitfähigkeit jedoch nicht reguliert werden.A heat conducting plate is known, which quickly absorbs the heat by means of an evaporating heat transfer medium from side to side. With this plate, however, the thermal conductivity cannot be regulated.

Der Erfindung liegt die Aufgabe zugrunde, eine Platte zu schaffen", deren Wärmedurchgang regulierbar ist, so daß beispielsweise eine Abstrahlung aus einem Raum nachts begünstigt und eine Wärmeeinstrahlung in diesen Raum tagsüber verhindert werden kann.The invention is based on the object of creating a plate "whose heat transfer can be regulated," see above that, for example, favors radiation from a room at night and heat radiation in this space can be prevented during the day.

Die Erfindung löst diese Aufgabe dadurch, daß ein Reflektorblech mit einer Vielzahl von Perforationen in dem Hohlraum zwischen den Wänden bewegbar angeordnet ist, und daß eine Einrichtung zum Bewegen des Reflektorbleches zur Erzeugung von Wirbelströmen im Hohlraum zur Steigerung der Wärmeübertragung von einer Wand zur andern vorgesehen ist.The invention solves this problem in that a reflector plate with a plurality of perforations in the cavity between the walls is movably arranged, and that means for moving the reflector plate to generate eddy currents in the cavity to increase the heat transfer from one wall to the other is provided.

Hierdurch ist es möglich, die Isoliereigenschaft dieser Platte durch einfaches bewegen des Reflektorbleches zu verringern.This makes it possible to increase the insulating properties of this plate by simply moving the reflector plate to decrease.

Anhand der Figuren wird die Erfindung beispielsweise erläutert. Es zeigtThe invention is explained by way of example with the aid of the figures. It shows

Fig. 1 eine perspektivische Teilschnittansicht einer Platte nach der Erfindung undFig. 1 is a perspective partial sectional view of a Plate according to the invention and

F i g. 2 eine mit Abbruchen dargestellte Seitenansicht der in F i g. 1 dargestellten Platte in kleinerem Maßstab.F i g. 2 is a side view shown with breaks the in F i g. 1 shown plate on a smaller scale.

Die in Fig. 1 dargestellte Platte weist eine äußere Wandung 232, die der Außenseite eines Raumes oder Gebäudes zugewandt sein kann, sowie eine innere Wandung 230 auf, die einen Hohlraum 237 begrenzen kann. In der Kammer ist ein Reflektorblech 233 zwischen den Wandungen 230 und 232 beweglich angebracht und weist eine Anzahl von Perforationen 235 auf.The plate shown in FIG. 1 has an outer wall 232, which can face the outside of a room or building, and an inner wall 230 which can delimit a cavity 237. A reflector plate 233 is movably mounted in the chamber between the walls 230 and 232 and has a number of perforations 235 .

Zum Bewegen des Reflektorbleches 233 in der Kammer dient die elektromagnetische Vibratoren aufweisende Einrichtung 234. die Ströme von Luft oder Gas erzeugen, die durch die Perforationen 235 fließen können und dadurch Wärme von einer Wandung zur anderen übertragen. Vorzugsweise werden die Vibratoren bzw. Schwingungserzeuger mit Wechselstrom bei Unterschallfrequenz gespeist, so daß die Perforationen 235 als Düsen wirken, wenn das Reflektorblech 233 mit Unterschallfrequenz bewegt wird. The device 234 , which has electromagnetic vibrators, is used to move the reflector plate 233 in the chamber, which generates currents of air or gas which can flow through the perforations 235 and thereby transfer heat from one wall to the other. The vibrators or oscillation generators are preferably fed with alternating current at a subsonic frequency, so that the perforations 235 act as nozzles when the reflector plate 233 is moved at a subsonic frequency.

An den Wandungen innerhalb der Kammer sind Rippen 231 und 236 angebracht, die zur wirksamen Vergrößerung der Wärmeaustauschfläche der Wandungen dienen, die den Wirbelströmen ausgesetzt ist, und gleichzeitig die Konvektionsströmung verringern, wenn das Reflektorblech 233 sich in Ruhestellung befindet. Ribs 231 and 236 are attached to the walls within the chamber, which serve to effectively increase the heat exchange area of the walls exposed to the eddy currents and at the same time reduce the convection flow when the reflector plate 233 is at rest.

Zusätzlich kann ein Wärmespeicherelement 230' vorgesehen sein, das an einer Seite von der Wandung 230 begrenzt ist. Vorzugsweise enthält das Wärmespeicherelement eine Wärmespeichermasse mit einem hohen latenten Wärmespeichervermögen beim Übergang von einem festen Zustand in einen flüssigen Zustand.In addition, a heat storage element 230 ′ can be provided, which is delimited on one side by the wall 230. The heat storage element preferably contains a heat storage mass with a high latent heat storage capacity during the transition from a solid state to a liquid state.

Die Vorrichtung arbeitet wie folgt: Während eines heißen Sommertages werden die Solenoide der elektromagnetischen Vibratoren nicht mit Strom versorgt, so daß keine Ströme innerhalb der Kammer erzeugt werden und keine Luft durch die Perforationen 235 fließt. Die stillstehende Luft bzw. das stillstehende Gas in der Kammer wirkt als Isolator und verhindert einen Wärmeübergang von der den Sonnenstrahlen ausgesetzten äußeren Wandung 232 zur inneren Wandung 230. Darüber hinaus reduziert das Reflektorblech 233, da es reflektierend wirkt, den Wärmeübergang durch Strahlung. Wenn der Wärmeübergang zwischen den beiden Wänden erhöht werden soll, werden die elektromagnetischen Vibratoren erregt und bewegen dadurch das Reflektorblech 233, wodurch Luft durch die Düsen 235 strömt und Wärme von einer Wandung zur anderen überträgt. Das geschieht normalerweise während einer Sommernacht, wenn die innere Wandung 230 wärmer ist als die äußere Wandung 232 und ein Wärmeübergang von der Wandung 230 zur Wandung 232 erwünscht ist. Wird ein Wärmespeicherelement 230' verwendet, so absorbiert dieses während des Tages, wenn die Solenoide nicht erregt werden. Wärme aus dem Raum, um eine Kühlwirkung zu erzielen. Diese Wärme wird dann nachts wenn die Vibratoren in Betrieb sind, an die äußere Wandung 232 übertragen.The device works as follows: During a hot summer day, the solenoids of the electromagnetic vibrators are not energized so that no currents are generated within the chamber and no air flows through the perforations 235. The still air or the still gas in the chamber acts as an insulator and prevents heat transfer from the outer wall 232 exposed to the sun's rays to the inner wall 230. In addition, the reflector plate 233, since it has a reflective effect, reduces the heat transfer through radiation. If the heat transfer between the two walls is to be increased, the electromagnetic vibrators are excited and thereby move the reflector plate 233, whereby air flows through the nozzles 235 and transfers heat from one wall to the other. This normally happens during a summer night when the inner wall 230 is warmer than the outer wall 232 and heat transfer from the wall 230 to the wall 232 is desired. If a heat storage element 230 'is used, this absorbs it during the day when the solenoids are not energized. Heat from the room to achieve a cooling effect. This heat is then transferred to the outer wall 232 at night when the vibrators are in operation.

Die beschriebene Platte mit veränderlichem Wärmedurchgang ist auch zur Verwendung im Winter geeignet, wenn die Sonnenwärme zum Aufwärmen der Innenseite eines Raumes ausgenutzt werden soll. In diesem Fall wird einfach die Zeitsteuerung des Betriebes umgekehrt, das heißt, daß die Vibratoren während des Tages mit Strom versorgt werden, um Sonnenwärme von der äußeren Wandung 232 zur inneren Wandung 230 zu übertragen und, wenn ein Wärmespeicherelement vorgesehen ist, anschließend an das Wärmespeicherelement. Bei Nacht oder zu irgendeiner beliebigen Zeit, wenn die auf äußere Wandung 232 wirkende Sonnenenergie zur Wärmeübertragung nicht ausreicht, werden die Vibratoren nicht mit Strom versorgt, so daß die Isoliereigenschaften der Platte erhöht werden.The described panel with variable heat transfer is also suitable for use in winter, when the sun's heat is to be used to warm up the inside of a room. In this case simply reverses the timing of the operation, that is, the vibrators during the day powered to add solar heat from the outer wall 232 to the inner wall 230 transferred and, if a heat storage element is provided, then to the heat storage element. At night or at any time when the solar energy acting on outer wall 232 is insufficient for heat transfer, the vibrators are not supplied with power, so that the The insulating properties of the plate are increased.
