Description
DEUTSCHESGERMAN
Es handelt sich um eine Einrichtung, die es ermöglicht, in dielektrische Körper Mikrowellen einzustrahlen. Derartige Einrichtungen eignen sich besonders zur Trocknung und Verleimung von Holz.It is a device that makes it possible to radiate microwaves into dielectric bodies. Such devices are particularly suitable for drying and gluing wood.
Im folgenden sollen die besonderen Vorteile der Mikrowellenbehandlung gegenüber der Verwendung von längeren Wellen herausgestellt werden. Die Vorteile liegen in der Möglichkeit der Einstrahlung, d. h. der freien wie der leitungsgeführten Strahlung. Strahlung bedeutet einen Transport von Energie, die den Sender verlassen hat und zunächst in keiner Kopplung mehr mit dem Sender steht. Sie kann höchstens durch Reflexion oder sonstige Umleitung wieder in den Sender zurückgeführt werden und dadurch die Wirkung einer effektiven Kopplung erlangen. Da es sich aber bei den hier beschriebenen Anwendungen um eine möglichst hohe Umsetzung der erzeugten Mikrowellenenergie im Objekt handelt, kommt es darauf an, daß nur ein Bruchteil der Energie zum Sender zurückgelangt. Man kann die Einrichtung so ausbilden, daß sich die Strahlung im Objekt »totläuft«, so daß Rückwirkungen auf den Sender verschwinden. Das ist aber nur im Mikrowellenbetrieb möglich, da die Wellenlänge kleiner als das Objekt gehalten werden muß. Bei längeren Wellen ist das Objekt immer direkt oder indirekt ein Teil des Schwingungskreises, wobei alle Schwierigkeiten auftreten, die im technischen Betrieb mit einer Kopplung auf den Sender verbunden sind.The following are the particular advantages of microwave treatment compared to the use to be highlighted by longer waves. The advantages lie in the possibility of irradiation, i. H. the free as well as the conducted radiation. Radiation means a transport of energy that the Has left the transmitter and is initially no longer linked to the transmitter. At most she can get through Reflection or other diversion are fed back into the transmitter and thereby the effect effective coupling. But since the applications described here are The highest possible conversion of the generated microwave energy in the object is important, that only a fraction of the energy is returned to the transmitter. One can train the institution so that the radiation "dies" in the object, so that repercussions on the transmitter disappear. That is but only possible in microwave operation, since the wavelengths are kept smaller than the object got to. With longer waves the object is always directly or indirectly a part of the oscillation circle, whereby all difficulties arise in the technical operation associated with a coupling to the transmitter are.
Die genannten Vorteile werden unter Vermeidung der aufgeführten Mängel bei der Einrichtung zur Einstrahlung von Mikrowellenenergie in dielektrische Körper, deren Ausdehnung gleich oder größer als eine halbe Wellenlänge ist, erfindungsgemäß durch einen eine leitungsgebundene Strahlung erzeugenden Strahler sowie im Strahlungsfeld angeordnete Einrichtungen zur Konzentrierung des innerhalb des Körpers erzeugten Feldes erreicht.The advantages mentioned are aimed at avoiding the listed deficiencies in the establishment Radiation of microwave energy into dielectric bodies, the extent of which is equal to or greater than a half a wavelength is, according to the invention, by a radiator which generates a line-bound radiation as well as devices arranged in the radiation field for concentrating the generated within the body Field reached.
Die Erfindung sei an Hand der nachstehend aufgeführten Beispiele erläutert.The invention is illustrated with the aid of the examples given below.
Die Beispiele zeigen Ausführungsformen der Einrichtung nach der Erfindung. Dabei wird eine homogene Einstrahlung in Streifen oder Flächen erzielt, die eine gleiche oder größere Ausdehnung als eine halbe Wellenlänge haben.The examples show embodiments of the device according to the invention. It becomes a homogeneous Radiation achieved in strips or areas that are equal to or greater than half an extent Have wavelength.
