Abstract
Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Kühlen von Bestrahlungsvorrichtungen gemäß den Oberbegriffen der Ansprüche 1 und 6.The The invention relates to a method and a device for cooling of irradiation devices according to the preambles of claims 1 and 6.
Eine
Bestrahlungsvorrichtung der eingangs genannten Art ist aus der
Um die Grenztemperaturen einzuhalten, ist es bekannt, die Strahler mit Luftströmungen, beispielsweise durch Prozessluft konvektiv zu kühlen. Dieses kann sowohl durch ein aktives Anblasen oder durch ein Ansaugen der Prozessluft in das Gehäuse des Strahlers erfolgen.Around To comply with the limit temperatures, it is known the radiator with air currents, for example by process air convective to cool. This can both by an active blowing or by sucking the process air into the housing of the Radiator done.
Ein
Beispiel für die Kühlung von Strahler und Einschmelzungen
in einem Gehäuse mit geschlossener Luftführung
zeigt die
Aufgabe der vorliegenden Erfindung ist es, ein Verfahren zum Kühlen von Bestrahlungsvorrichtungen anzugeben, bei dem im Stand-By-Betrieb die Betriebsleistung gesenkt und gleichzeitig eine erhöhte Lebensdauer erreicht werden kann.task The present invention is a method for cooling indicate irradiation devices in which in stand-by mode lowered the operating performance while increasing it Lifespan can be achieved.
Die Aufgabe wird durch die in den Patentansprüchen 1 und 6 genannten Merkmale gelöst. Dabei gingen die Erfinder davon aus, dass die Aufgabe der Kühlung je nach Betriebszustand unterschiedlich ist und daher eine Optimierung der Betriebsleistung nur durch eine getrennte Führung der Kühlströme möglich ist. Eine weitere Erkenntnis war, dass die Kühlung des Strahlers bei geschlossenem Schottensystem mit einer geringen Luftmenge auskommt, die sich dabei jedoch stark erwärmt. Der Bereich der Einschmelzungen hingegen muss stetig aus einer kühlen Umgebung mit Kühlgas umströmt werden, sodass hier auch bei reduziertem Betrieb eine effiziente Kühlung ermöglicht wird.The The object is achieved by the in the claims 1 and 6 solved mentioned features. The inventors went away from that task of cooling depending on the operating condition is different and therefore an optimization of the operating performance only by a separate guidance of the cooling streams is possible. Another finding was that the cooling of the radiator with closed Schottensystem with a small Air quantity gets along, but it heats up strongly. The area of the melts, on the other hand, must constantly cool off Surroundings are flowed around with cooling gas, so here Even with reduced operation allows efficient cooling becomes.
Ferner wurde als vorteilhaft erkannt, das Schottensystem so auszubilden, dass die Einschmelzungen unabhängig vom Öffnungszustand mit Kühlluft versorgt werden, auch wenn das Gesamtvolumen der Kühlströme stark zurückgeht.Further was found to be advantageous to form the Schottensystem so that the melts regardless of the opening state be supplied with cooling air, even if the total volume of Cooling currents drops sharply.
Bei den vorgeschlagenen Maßnahmen sind jedoch gewisse Grenzwerte zu beachten. So darf eine Änderung der Luftströmung nicht dazu führen, dass zusätzliche Volumenströme zur Kühlung erforderlich werden oder Grenztemperaturen erreicht oder sogar überschritten werden. Auch ein Unterschreiten der Grenztemperatur ist kritisch, da eine Unterkühlung der Strahler zu einer Betriebsunterbrechung führt. Einschmelzungen und Korpus des Strahlers erwärmen sich mit steigender Strahlerleistung unterschiedlich, sodass die Einstellung der Kühlströme für den Teillastbetrieb erforderlich ist.at However, the proposed measures are subject to certain limits to be observed. So may a change in the air flow do not cause additional flow rates required for cooling or limit temperatures reached or even exceeded. Also a fall below the limit temperature is critical because of hypothermia the spotlight leads to a business interruption. inclusions and body of the radiator heat up with increasing radiator power different, so the adjustment of the cooling currents is required for partial load operation.
Im Folgenden wird die Erfindung anhand eines Ausführungsbeispieles und dreier Figuren näher erläutert. Es zeigen:in the The invention is based on an exemplary embodiment and three figures explained in more detail. Show it:
Der
Strahlungsquelle ist durch ein Schottensystem, bestehend aus zwei
Schottenhälften
- – Kühlstrom A zwischen Gehäuse
1 und Schottensystem, wobei über seitliche Luftöffnungen5 im Gehäuse1 Umgebungsluft angesaugt werden kann - – Kühlstrom B im Innern des Schottensystems zur Kühlung der Strahlungsquelle
- – Kühlstrom C im Bereich der Einschmelzungen, wobei
die Einschmelzkühlung über einen oberen Luftkanal
6 , einen unteren Luftkanal8 und einen Absaugkanal7 im Gehäuse erfolgt.
- - Cooling current A between housing
1 and Schottensystem, with over lateral air openings5 in the case1 Ambient air can be sucked in - - Cooling B in the interior of the bulkhead system for cooling the radiation source
- - Cooling flow C in the region of the melts, wherein the melt-cooling via an upper air duct
6 , a lower air duct8th and a suction channel7 takes place in the housing.
Diese
Darstellung zeigt deutlich, dass den Einschmelzungen im offenen
wie im geschlossenen Zustand des Schottensystems über den
Luftkanal
Es
sind verschiedenen Konstruktionen für die Ausbildung des
Schottensystems und für die Ausbildung und Anbringung der
Kühlluftkanäle denkbar. Beispielsweise kann das
Schottensystem über die zu kühlende Einschmelzung
In
einem bevorzugten Anwendungsfall kann im Bereich der Einschmelzung
Kühlstrom B zu Kühlstrom C 1:10, vorzugsweise
1:15 bis 1:50. Dieser Strömungsfaktor ist für
die erfindungsgemäße Wirkung zu beachten, damit
die Einschmelzung auch bei geschlossenem Schottensystem ausreichend
gekühlt wird.In a preferred application, in the field of melting
Cooling flow B to cooling flow C 1:10, preferably 1:15 to 1:50. This flow factor must be taken into account for the effect according to the invention, so that the melting is adequately cooled even when the sheet system is closed.
Die Steuerung der abgegebenen Strahlungsleistung erfolgt grundsätzlich über die zugeführte Energie, sie kann aber auch in gewissen Grenzen über die beweglichen Schotten erfolgen. Mit dem erfindungsgemäßen Verfahren gemäß Anspruch 1 und der konstruktiven Lösung gemäß Vorrichtungsanspruch 6 soll die Kühlung der Bestrahlungsvorrichtung so durchgeführt werden, dass die entstehende Wärme möglichst durch den Kühlstrom abgeführt wird und zwar unabhängig davon, wie die Stellung der Schotten im jeweiligen Betriebszustand ist.The Control of the emitted radiation power is basically about the energy supplied, but it can also be certain Limits are made via the movable bulkheads. With the inventive method according to claim 1 and the constructive solution according to device claim 6, the cooling of the irradiation device should be carried out in this way be that the resulting heat as possible through the cooling flow is discharged and that independently of it, as the position of the Scots in the respective operating state is.
Anhand
von Versuchen wurde ermittelt, dass der Durchmesser von Luftkanälen
im Bereich der Einschmelzkühlung so bemessen sein sollte,
dass er maximal 1,5-mal Durchmesser Einschmelzung erreicht. Bei üblichen
Strahlerabmessungen kann der untere Luftkanal
Vorzugsweise
können die Strahlerenden mit dem Keramikende
Mit der erfindungsgemäßen Lösung ist es möglich, bei einer Absenkung der Strahlerleistung im Stand-By-Betrieb auf 30% ein Ausblasen des Strahlers mit Sicherheit zu verhindern und trotzdem eine effektive Kühlung an den Einschmelzungen zu erreichen. Gleichzeitig konnte die erforderliche Kühlluftmenge im Stand-By-Betrieb reduziert werden, was sich wiederum günstig auf den Energieverbrauch der erfindungsgemäßen Bestrahlungsvorrichtung auswirkt.With The solution according to the invention makes it possible to at a lowering of the radiator power in stand-by mode on 30% to prevent blowing out of the spotlight with certainty and nevertheless an effective cooling at the melts to reach. At the same time, the required amount of cooling air be reduced in standby mode, which in turn is favorable on the energy consumption of the invention Irradiation device effects.
