Description
Lüftersystem Die Erfindung betrifft ein Lüftersystern zur Kühlung eines elektromagnetische Wellen erzeugenden Oszillators, dessen Frequenz von seiner Temperatur abhängig ist.Fan system The invention relates to a fan system for cooling an oscillator producing electromagnetic waves, the frequency of which is different from its Temperature is dependent.
Sie soll an Hand der Figur näher erläutert werden: Ein Thermoelement 4 ist in der Nähe des Gegenstandes 3, beispielsweise eines Oszillators für Mikrowellen, angeordnet, dessen Temperatur konstant gehalten werden soll. Seine Ausgangsspannung, die von seiner Temperatur abhängt, wird in einem Gleichstromverstärker 5 verstärkt und steuert die Frequenz eines Rechteckwellengenerators 1 mittels der magnetischen Sättigung eines Eisenkernes. Zu diesem Zweck brauchbare Rechteckwellengeneratoren sind bekannt und soffen daher nicht der Gegenstand der vorliegenden Erfindung sein. Wenn sich nun die Temperatur des Oszillators verändert, so wirkt sich das auf die Ausgangsspannung des Thermoelementes aus. Es ändert sich demnach auch entsprechend die Frequenz des Rechteckwellengenerators. Mit seiner Ausgangsspannung wird der Synchronmotor des Ventilators 2 angetrieben, dessen Umdrehungszahl von der Frequenz seiner Speisespannung abhängig ist. Damit wird der kühlende Frischluftstrom automatisch im Sinne einer Temperaturstabilisierung des Oszillators gesteuert.It will be explained in more detail with reference to the figure: A thermocouple 4 is arranged in the vicinity of the object 3, for example an oscillator for microwaves, the temperature of which is to be kept constant. Its output voltage, which depends on its temperature, is amplified in a direct current amplifier 5 and controls the frequency of a square wave generator 1 by means of the magnetic saturation of an iron core. Square wave generators which can be used for this purpose are known and should therefore not be the subject of the present invention. If the temperature of the oscillator changes, this affects the output voltage of the thermocouple. Accordingly, the frequency of the square wave generator also changes accordingly. The synchronous motor of the fan 2 is driven with its output voltage, the speed of which depends on the frequency of its supply voltage. In this way, the cooling fresh air flow is automatically controlled to stabilize the temperature of the oscillator.
Wenn auch andere in der Frequenz regelbare Generatoren für den vorliegenden Zweck verwendet werden können, so bietet ein Rechteckwellengenerator mit gesättigtem Eisenkern doch den Vorteil einer sehr wirksamen Schwingung. Ferner wird durch ihn der konstruktive Aufbau der gesamten Anordnung wesentlich vereinfacht, da die Frequenz seiner Schwingungen annähernd zu seiner Speisespannung proportional ist.Albeit other generators with adjustable frequency for the present one Purpose can be used so provides a square wave generator with saturated Iron core has the advantage of a very effective vibration. Further becomes through him the structural design of the entire arrangement is significantly simplified, since the frequency its oscillations is approximately proportional to its supply voltage.
An Stelle des Thermoelementes kann auch ein Thermistor und an Stelle des Synchromnotors ein Induktionsmotor verwendet werden. Auch der Einsatz eines andersartigen Frequenzoszillators 1 ist denkbar.A thermistor can be used instead of the thermocouple and an induction motor can be used instead of the synchromesh motor. The use of a different type of frequency oscillator 1 is also conceivable.
Alle diese möglichen Variationen gehören jedoch ebenfalls zu der mit der Erfindung vorgeschlagenen Lösung.However, all of these possible variations also belong to the with the solution proposed by the invention.
