Description

Isotherm beheizbare glasklare MehrfachverglasungIsothermally heated, crystal-clear multiple glazing

Die Erfindung betrifft eine Verglasung mit mindestens zwei Scheiben und einer zwischen den Scheiben befindlichen geheizten Kammer, die Kondensationszone eines Flächenwärmerohres (heat-plpe) ist.The invention relates to glazing with at least two panes and a heated chamber located between the disks, the condensation zone of a surface heat pipe (heat-plpe).

Es ist bekannt, Scheiben in Verkehrsmitteln und Gebäuden durch das Anblasen mit vorgewärmter Luft beschlagfrei und eisfrei zu halten. Häufig sind solche Scheiben jedoch nur in unmittelbarer Nähe der Die nach längerer Anlaufzeit durchsichtig und es ist kaum möglich, Aussere Fensterflächen transparent zu halten, da hierzu aufwendige Luftführungen notwendig sind. In öffentlichen Verkehrsmitteln beschränkt man sich deshalb in der Regel darauf, die Front scheiben durchsichtig zu erhalten, während die Seitenschei ben insbesondere im Winter nicht mehr transparent, sondern allenfalls tranaluzent sind.It is known to use disks in vehicles and buildings Blowing on with preheated air to keep it free of fog and ice. Often there are However, panes are only transparent in the immediate vicinity of the die after a long start-up time and it is hardly possible to keep outside window surfaces transparent, because this is the case complex air ducts are necessary. Limited in public transport you therefore usually rely on keeping the front panels transparent, while the side windows are no longer transparent, especially in winter, but at best are tranalucent.

Es ist weiter bekannt, bei Verglasungen mit mindestens zwei Scheiben und einer zwischen dn Scheiben befindlichen Kammer diese mit warmer Luft zu beheizen. Ist die Luft nicht staubfrei, so werden sich in kürzerer Zeit Staubablagerungen bilden, die kaum entfernbar sind; fällt die Heizeinrichtung aus, so beschlagen die Scheiben von innen.It is also known for glazing with at least two panes and one between the discs Chamber these with warm To heat air. If the air is not free of dust, it will be in less time Form dust deposits that can hardly be removed; the heater fails, so the windows fog up from the inside.

Der Erfindung liegt die Aufgabe zugrunde, eine isotherm beheizbare Mehrfachverglasung zu schaffen, die selbst unter schwierigsten Bedingungen glasklar ist und die sowohl innenseitig wie aussenseitig und in ihrem Inneren beschlagfrei ist. Die Scheibe soll darüberhinaus bereits nach kurzer Zeit eisfrei sein.The invention is based on the object of an isothermally heatable Create multiple glazing that is crystal clear even under the most difficult conditions and which is fog-free both on the inside and on the outside and inside is. The disc should also be free of ice after a short time.

Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass die Kammer zwischen den beiden Scheiben die Kondensationszone eines Flächenwärmerohres ist und ein ausserhalb der Scheibe befindlicher Verdampferteil vorhanden ist und sich zwischen Verdampferteil und Kondensationszone im Dampfraum ein Drahtgewebe befindet. Dieses Drahtgewebe oder auch eine perforierte Scheibe oder ein Sintermaterial dient dazu, durch Siedeverzüge ausgeworfene Flüssigkeitströpfchen des Wärmeträgers abzufangen.According to the invention, this object is achieved in that the chamber between the two panes is the condensation zone of a surface heat pipe and an evaporator part located outside the disc is present and itself There is a wire mesh between the evaporator part and the condensation zone in the steam space. This wire mesh or a perforated disc or a sintered material is used to intercept liquid droplets of the heat transfer medium ejected by delayed boiling.

Bei Dreifachverglasung wird zweckmässigerweise die dem Innenraum benachbarte Kammer als Kondensationszone gestaltet, während die äussere Kammer eine Isolationskammer ist.In the case of triple glazing, the one next to the interior is expediently Chamber designed as a condensation zone, while the outer chamber is an isolation chamber is.

Der Verdampferteil ist mit Kapillaren z. B. in Form eines Drahtgewebes ausgekleidet, um eine grössere Oberfläche zu erzielen und einen Füllmengenausgleich zu ermöglichen. In vorteilhafter Weise ist der Verdampferteil horizontal angeordnet und die Kapillare sorgen für den Flüssigkeitstransport des Wärmeträgers.The evaporator part is z. B. in the form of a wire mesh lined in order to achieve a larger surface and a fill volume compensation to enable. The evaporator part is advantageously arranged horizontally and the capillary ensure the liquid transport of the heat carrier.

Der Verdampferteil besteht in vorteilhafter Weiterbildung der Erfindung aus einem metallischen Werkstoff, wodurch der Wärmeübergang sowohl bei elektrischer wie auch bei Warmwasserheizung erheblich verbessert wird. Ausserdem ist ein metallischer Verdampferteil nahezu zerstörungsfrei und er ermöglicht eine leichtere Befü#lbarkeit mit dem Wärmeträger nach bekannter Technologie. Zu Reparaturzwecken können Verdampferteil und Kondensatorteil lösbar ausgeführt werden. Als Wärmeträger für die beheizte Kammer kommen Alkohol insbesondere Methanol sowie Aceton in Frage.The evaporator part is an advantageous development of the invention made of a metallic material, whereby the heat transfer both with electrical as is also significantly improved with hot water heating. There is also a metallic one The evaporator part is almost non-destructive and allows easier filling with the heat transfer medium according to known technology. Vaporizer parts can be used for repair purposes and the condenser part are detachable. As a heat transfer medium for the heated chamber Alcohol, in particular, methanol and acetone are suitable.

Ist die Druckdifferenz zwischen dem Dampfdruck im Kondensatorteil und der Umgebung bei Scheiben grösserer Abmessung kritisch, so können Stützstellen die beiden Glasscheiben miteinander verbinden. In mrteilhafter Weise sind solche Stützstellen strömungsgünstig z. B. elliptisch oder tropfenförmig ausgebildet, damit der kondensierte Wärmeträger die Stützstellen ohne Störungen umfliessen kann und Schlierenbildung vermieden wird.Is the pressure difference between the vapor pressure in the condenser part and the surroundings are critical in the case of panes of larger dimensions, so support points can be connect the two panes of glass together. In a judgmental way such are Support points streamlined z. B. elliptical or teardrop-shaped so that the condensed heat transfer medium can flow around the support points without interference and The formation of streaks is avoided.
