Description
Die Erfindung betrifft eine Umgebungslärmabschirmvorrichtung sowie ein Verfahren zur Abschirmung eines Gerätes vor Umgebungslärm.The invention relates to an environmental noise shielding device and a method for shielding a device from environmental noise.
Aus der Praxis sind Vorrichtungen zur akustischen Abschirmung von empfindlichen Geräten bekannt. Besonders in der Halbleiterindustrie werden sogenannte akustische Hauben zur Abschirmung von empfindlichen Inspektionsmaschinen verwendet.In practice, devices for acoustic shielding of sensitive devices are known. Especially in the semiconductor industry so-called acoustic hoods are used to shield sensitive inspection machines.
Ein derartiges schallschluckend ausgebildetes Gehäuse wirkt zumeist zugleich auch isolierend gegenüber Wärme. Daher kann es, insbesondere, wenn ein Gerät in das Gehäuse eingebracht wird, welches Abwärme produziert, zu signifikanten Temperaturerhöhungen des Innenraumes des Gehäuses kommen. Eine derartige Temperaturerhöhung ist in vielen Fällen unerwünscht. Besonders bei Verwendung eines Gehäuses zur Isolierung von Inspektionsgeräten in der Halbleiterindustrie ist es erwünscht, dass der Innenraum der Schallschutzhaube im Wesentlichen dieselbe Temperatur wie der Außenbereich aufweist, damit beispielsweise Wafer, welche in den Innenraum eingebracht werden, keinen Temperaturschwankungen unterworfen sind.Such a sound-absorbing housing usually acts at the same time also insulating against heat. Therefore, especially when a device is introduced into the housing, which produces waste heat, it can lead to significant temperature increases of the interior of the housing. Such a temperature increase is undesirable in many cases. Especially when using a housing for the insulation of inspection equipment in the semiconductor industry, it is desirable that the interior of the soundproof hood has substantially the same temperature as the outdoor area, so that, for example, wafers, which are introduced into the interior, are not subject to temperature fluctuations.
Man hat in der Praxis versucht, die Erwärmung derartiger Schallschutzhauben durch Belüftungen zu reduzieren.Attempts have been made in practice to reduce the heating of such soundproof hoods by venting.
Nachteilig an derartigen Belüftungen ist, dass auch wenn diese in besonderer Weise schallschluckend aufgebaut sind, zumeist immer noch auch eine Durchtrittsöffnung auch für Schall geschaffen wird, wodurch die Schallisolationswirkung des Gehäuses verringert wird.A disadvantage of such vents is that even if they are constructed sound absorbing in a special way, usually still a passage opening is created for sound, whereby the soundproofing effect of the housing is reduced.
Der Erfindung liegt demgegenüber die Aufgabe zugrunde, eine Vorrichtung zum Schutz eines empfindlichen Gerätes vor Umgebungslärm bereitzustellen, bei welcher die genannten Nachteile des Standes der Technik reduziert sind.The invention is based on the object to provide a device for protecting a sensitive device from environmental noise, in which the mentioned disadvantages of the prior art are reduced.
Insbesondere ist Aufgabe der Erfindung, eine Vorrichtung bereitzustellen, mit welcher die Schallschutzwirkung verbessert wird.In particular, object of the invention to provide a device with which the soundproofing effect is improved.
Weiter ist Aufgabe der Erfindung, eine Schallschutzvorrichtung bereitzustellen, bei welcher die Innentemperatur auf dem Niveau der Außentemperatur gehalten werden kann.Another object of the invention to provide a soundproofing device, wherein the internal temperature can be maintained at the level of the outside temperature.
Die Aufgabe der Erfindung wird bereits durch eine Umgebungslärmabschirmvorrichtung sowie durch ein Verfahren zur Abschirmung eines Gerätes vor Umgebungsschall nach einem der unabhängigen Ansprüche gelöst.The object of the invention is already achieved by a Umweltlärmabschirmvorrichtung and by a method for shielding a device from ambient sound according to one of the independent claims.
Bevorzugte Ausführungsformen und Weiterbildungen der Erfindung sind den jeweiligen Unteransprüchen zu entnehmen.Preferred embodiments and further developments of the invention are to be taken from the respective subclaims.
Danach ist eine Umgebungslärmabschirmvorrichtung vorgesehen, welche ein Gehäuse umfasst, das einen Raum zur Aufnahme eines isolierenden Gerätes definiert.Thereafter, an environmental noise shielding device is provided which includes a housing defining a space for housing an insulating device.
Unter einer Umgebungslärmabschirmvorrichtung wird eine Vorrichtung verstanden, in welcher ein zu isolierendes Gerät angeordnet werden kann, und bei welcher die Lautstärke durch das Gehäuse der Vorrichtung reduziert wird, der Schallpegel also in dem Raum zur Aufnahme eines zu isolierenden Gerätes geringer ist als in der Umgebung.An ambient noise shielding device is understood to mean a device in which a device to be insulated can be arranged, and in which the volume is reduced by the housing of the device, the sound level is therefore lower in the space for receiving a device to be insulated than in the environment.
Gemäß der Erfindung ist in dem Raum zumindest ein Kühlelement angeordnet. Unter einem Kühlelement wird jegliche Vorrichtung verstanden, mit der der Raum zur Aufnahme des zu isolierenden Gerätes abgekühlt werden kann.According to the invention, at least one cooling element is arranged in the space. A cooling element is understood to be any device with which the space for receiving the device to be insulated can be cooled.
Das Kühlelement ist bei einer bevorzugten Ausführungsform der Erfindung mit zumindest einer Versorgungseinrichtung gekoppelt, welche außerhalb des Gerätes angeordnet ist. Die Versorgungseinrichtung ist vorzugsweise im Wesentlichen von dem Gehäuse entkoppelt, das heißt Schwingungen der Versorgungseinrichtung werden nicht auf das Gehäuse des zu isolierenden Gerätes übertragen.The cooling element is coupled in a preferred embodiment of the invention with at least one supply device, which is arranged outside of the device. The supply device is preferably substantially decoupled from the housing, that is to say vibrations of the supply device are not transmitted to the housing of the device to be insulated.
Zur Kühlung können beispielsweise Kompressorkühlelemente, Peltier-Elemente oder Kühlschlangenkreisläufe verwendet werden, welche an eine oder mehrere Stellen der Innenwand des Gehäuses angebracht werden oder Teil der Wände oder der Decken sein können.For cooling, for example, compressor cooling elements, Peltier elements or cooling coil circuits may be used, which may be attached to one or more locations of the inner wall of the housing or may be part of the walls or ceilings.
Die Wahl des Kühlelementes richtet sich dabei in erster Linie nach den Anforderungen an die Kühlleistung. Da die Abwärme insbesondere von Inspektionsgeräten in der Halbleiterindustrie oft recht gering ist, reichen für viele Anwendungen Peltier-Elemente oder Kühlschlangenkreisläufe, in denen die Wärme über ein Fluid, insbesondere Wasser abgeführt wird. Für Anwendungen mit höherer Kühlleistung kann auch ein Kältemittelkompressor eingesetzt werden.The choice of the cooling element depends primarily on the requirements of the cooling capacity. Since the waste heat, in particular of inspection devices in the semiconductor industry, is often quite small, Peltier elements or cooling coil circuits in which the heat is dissipated via a fluid, in particular water, are sufficient for many applications. For applications with higher cooling capacity, a refrigerant compressor can also be used.
Flexible Leitungen sorgen dabei, wie es bei einer besonderen Ausführungsform der Erfindung vorgesehen ist, dass Schwingungen der Versorgungseinrichtung, insbesondere Schwingungen eines Kühlkompressors nicht oder nur in geringem Maße an das Gehäuse der Umgebungslärmabschirmvorrichtung weitergegeben werden.Flexible lines ensure, as is provided in a particular embodiment of the invention that vibrations of the supply device, in particular vibrations of a refrigerant compressor are not or only to a small extent to the housing of the ambient noise shielding device passed.
Das Kühlelement in dem Gehäuse der Umgebungslärmabschirmvorrichtung ist vorzugsweise derart ausgebildet, dass es einen Schallpegel von weniger als 30 dB, vorzugsweise von weniger als 20 dB und besonders bevorzugt von weniger als 15 dB erzeugt. Es werden also Kühlelemente verwendet, welche wenig, bevorzugt keinen Lärm im Inneren des Gehäuses erzeugen.The cooling element in the housing of the environmental noise shielding device is preferably designed to produce a sound level of less than 30 dB, preferably less than 20 dB, and more preferably less than 15 dB. Thus, cooling elements are used which generate little, preferably no noise inside the housing.
Idealerweise werden Kühlelemente verwendet, welche sogar keinen messbaren Schallpegel im Gehäuse emittieren. Dies ist besonders mit Kühlschlangen gut zu realisieren. Ein außerhalb der Umgebungslärmabschirmvorrichtung anordnete Versorgungseinrichtung, beispielsweise ein Wärmetauscher, kann dagegen Schall emittieren, ohne den Schallpegel in der Umgebungslärmabschirmvorrichtung nennenswert zu beinflussen. Eine außerhalb der Umgebungslärmabschirmvorrichtung angeordnete Versorgungseinrichtung ist in vielen Fällen auch gar nicht nötig und kann daher entfallen.Ideally, cooling elements are used which even emit no measurable sound level in the housing. This is easy to realize, especially with cooling coils. On the other hand, a supply means arranged outside the environmental noise shielding apparatus, for example, a heat exchanger, can emit sound without appreciably affecting the sound level in the environmental noise shielding apparatus. A supply device arranged outside the ambient noise shielding device is shown in FIG In many cases not necessary and therefore can be omitted.
Das oder die Kühlelemente sind vorzugsweise in die Wand oder Decke des Gehäuses integriert, insbesondere ist vorgesehen, ein Kühlelement im Wesentlichen in der Decke des Gehäuses unterzubringen.The one or more cooling elements are preferably integrated in the wall or ceiling of the housing, in particular it is provided to accommodate a cooling element substantially in the ceiling of the housing.
Bei einer Weiterbildung der Erfindung ist in dem Raum ein Temperatursensor angeordnet, welcher zur Regelung einer Versorgungseinrichtung für Kältemittel ausgebildet ist. Über einen derartigen Temperatursensor kann die Temperatur im Inneren des Gehäuses konstant gehalten werden.In one embodiment of the invention, a temperature sensor is arranged in the space, which is designed to control a supply device for refrigerant. About such a temperature sensor, the temperature can be kept constant inside the housing.
Bei einer alternativen Ausführungsform, wie es gemäß einer Weiterbildung der Erfindung vorgesehen ist, ist ein weiterer Temperatursensor außerhalb des Raumes angeordnet, mit welchem die Temperatur außerhalb des Gehäuses gemessen werden kann. So kann die Temperatur des Raumes im Gehäuse an die Außentemperatur angepasst werden. Temperaturschwankungen beim Verbringen von empfindlichen Geräten oder zu untersuchenden Bauteilen in die Umgebungslärmabschirmvorrichtung weitgehend vermieden.In an alternative embodiment, as provided according to a development of the invention, a further temperature sensor is arranged outside the room, with which the temperature outside the housing can be measured. Thus, the temperature of the room in the housing can be adapted to the outside temperature. Temperature fluctuations when moving sensitive devices or components to be examined in the ambient noise shield largely avoided.
Bei einer Weiterbildung der Erfindung weist die Umgebungslärmabschirmvorrichtung zumindest eine Öffnungsklappe auf, welche, wie bei einer bevorzugten Ausführungsform der Erfindung vorgesehen, automatisch betätigbar ist. So kann die Umgebungslärmabschirmvorrichtung in einem automatischen Transportsystem integriert werden, bei welchem beispielsweise zu untersuchende Proben über eine Automatisierungseinrichtung in das Gehäuse der Umgebungslärmabschirmvorrichtung verbracht werden.In a development of the invention, the environmental noise screening device has at least one opening flap which, as provided in a preferred embodiment of the invention, can be actuated automatically. Thus, the environmental noise shielding device can be integrated in an automatic transport system in which, for example, samples to be examined are brought into the housing of the environmental noise shielding device via an automation device.
Der Raum der Umgebungslärmabschirmvorrichtung ist vorzugsweise im Wesentlichen fluiddicht abschließbar. So wird die schallisolierende Wirkung erhöht und es ist eine genauere Temperaturregelung möglich.The space of the environmental noise shielding device is preferably substantially fluid-tight lockable. Thus, the sound-insulating effect is increased and it is a more accurate temperature control possible.
Der Raum nimmt vorzugsweise zwischen 0,2 und 7 und besonders bevorzugt zwischen 0,5 und 1,5 m3 Raum ein.The space preferably occupies between 0.2 and 7 and more preferably between 0.5 and 1.5 m 3 of space.
Durch die Erfindung lassen sich Umgebungslärmabschirmvorrichtungen bereitstellen, welche ein Schalldämmmaß bei einer Frequenz von 500 Hz und einem im Wesentlichen zu einer Gehäusewand verlaufenden senkrechten Einfallswinkel von über 5 dB, vorzugsweise über 10 dB und besonders bevorzugt über 40 dB aufweisen.By means of the invention, it is possible to provide environmental noise shielding devices which have a sound reduction index at a frequency of 500 Hz and a vertical angle of incidence substantially above a housing wall of more than 5 dB, preferably more than 10 dB and particularly preferably more than 40 dB.
Das Schalldämmmaß beträgt bei einer Frequenz von 250 Hz über 3 dB, bevorzugt über 8 dB und besonders bevorzugt über 30 dB.The Schalldämmmaß is at a frequency of 250 Hz over 3 dB, preferably above 8 dB and more preferably above 30 dB.
Bei einer Frequenz von 100 Hz beträgt das Schalldämmmaß über 15 dB, bevorzugt über 30 dB und besonders bevorzugt über 50 dB.At a frequency of 100 Hz, the sound reduction index is more than 15 dB, preferably more than 30 dB and particularly preferably more than 50 dB.
Die Erfindung betrifft des Weiteren ein Schwingungsisolationssystem, welches eine erfindungsgemäße Umgebungslärmabschirmvorrichtung umfasst.The invention further relates to a vibration isolation system comprising an environmental noise shielding device according to the invention.
Die Umgebungslärmabschirmvorrichtung ist dabei vorzugsweise schwingungsisoliert gelagert, insbesondere ist vorgesehen, die Umgebungslärmabschirmvorrichtung auf einer schwingungsisolierten Platte anzuordnen.The ambient noise shielding device is preferably mounted vibration-isolated, in particular it is provided to arrange the Umweltdärmabschirmvorrichtung on a vibration-isolated plate.
Weiter betrifft die Erfindung ein Verfahren zur Abschirmung eines Gerätes vor Umgebungsschall, wobei ein abzuschirmendes Gerät in ein Gehäuse eingebracht wird, das Gehäuse verschlossen wird und eine in dem Gehäuse angeordnete Kühlvorrichtung über ein ebenfalls in dem Gehäuse angeordneten Sensor geregelt wird.Furthermore, the invention relates to a method for shielding a device from ambient sound, wherein a device to be shielded is introduced into a housing, the housing is closed and a cooling device arranged in the housing is controlled by a sensor also arranged in the housing.
Bei einer Weiterbildung der Erfindung wird über einen weiteren Sensor, welcher außerhalb des Gehäuses angeordnet ist, die Temperatur im Gehäuse der Temperatur außerhalb des Gehäuses angepasst.In a development of the invention, the temperature in the housing is adapted outside the housing via a further sensor, which is arranged outside the housing.
