Description
Gebiet der ErfindungField of the invention
Diese Erfindung betrifft ein Verfahren zum Kühlen eines Gegenstands unter Verwendung eines Kryokühlers, sowie einen derartigen Kryokühler.These The invention relates to a method for cooling an article under Using a cryocooler, and such a cryocooler.
Beschreibung des Standes der TechnikDescription of the state of technology
Bei einem supraleitenden Filter auf dem Gebiet der IT-Kommunikation, einem supraleitenden MRI in der Medizintechnik oder auf dem Gebiet der Grundlagenforschung ist es notwendig, ein hochpräzises Elektronenmikroskop oder ein Hochleistungs-Präzisionsinstrument, beispielsweise einen hochempfindlichen Submillimeter-Wellendetektor oder einen Infrarotstrahlendetektor zu kühlen, um thermische Störungen zu beseitigen. Bei der Kühlung eines derartigen Hochleistungs-Präzisionsinstruments wird bislang verflüssigtes Gas oder ein Kryokühler verwendet. Unlängst wurde der Kühltemperaturbereich für den Kryokühler herab auf 4 K verbessert, der einfach auf Knopfdruck zu bedienen ist und konnte in der Vergangenheit unter Verwendung eines Kühlmittels extrem niedriger Temperatur realisiert werden.at a superconducting filter in the field of IT communication, a superconducting MRI in medical technology or in the field In basic research it is necessary to have a high-precision electron microscope or a high performance precision instrument, For example, a highly sensitive submillimeter wave detector or to cool an infrared ray detector to prevent thermal disturbances remove. When cooling a such high performance precision instruments is so far liquefied Gas or a cryocooler used. Recently became the cooling temperature range for the cryocooler improved down to 4K, which is easy to operate at the touch of a button is and could in the past using a coolant extremely low temperature can be realized.

ZUSAMMENFASSUNG DER ERFINDUNGSUMMARY OF THE INVENTION
Es ist eine Aufgabe der vorliegenden Erfindung, einen Gegenstand, beispielsweise ein Hochleistungs-Präzisionsinstrument auf extrem niedrige Temperaturen ohne Aufbringen von Vibrationen auf den Gegenstand zu kühlen.It It is an object of the present invention to provide an article, for example a high-performance precision instrument to extremely low temperatures without applying vibrations to cool on the object.
Zur Lösung der obigen Aufgabe betrifft die Erfindung ein Verfahren nach Anspruch 1 zur Kühlung eines Gegenstandes unter Verwendung eines Kryokühlers, sowie einen Kryokühler nach Anspruch 5.to solution the above object, the invention relates to a method according to claim 1 for cooling an object using a cryocooler, as well as a cryocooler Claim 5.
Die
Erfinder haben intensive Studien durchgeführt, um die oben beschriebene
Aufgabe zu lösen. Im
Ergebnis wurde die folgende Tatsache herausgefunden:
Das kalte
Ende ist in Kreisform ausgebildet und zwei Paare von Kühlzylindern
sind an der Hauptfläche
des kalten Endes angeordnet, so dass die Diagonallinie, die ein
Paar von Kühlzylindern
verbindet, senkrecht zur Diagonallinie ist, die das andere Paar
von Kühlzylindern
verbindet. Dann wird ein Hochdruckgas dem einen Paar von Kühlzylindern
zugeführt
und ein Niederdruckgas dem anderen Paar von Kühlzylindern. In diesem Fall
wird die Form des kalten Endes verformt, wie in
The cold end is formed in a circular shape and two pairs of cooling cylinders are arranged on the main surface of the cold end so that the diagonal line connecting a pair of cooling cylinders is perpendicular to the diagonal line connecting the other pair of cooling cylinders. Then, a high pressure gas is supplied to one pair of cooling cylinders and a low pressure gas to the other pair of cooling cylinders. In this case, the shape of the cold end is deformed as in
Wenn daher ein ortsfester Punkt auf den ortsfesten Bereich des kalten Endes festgelegt wird, und ein bestimmter Gegenstand unter Verwendung des ortsfesten Punktes gekühlt wird, kann der Gegenstand auf eine extrem niedrige Temperatur gekühlt werden, wobei Vibrationen zu dem Gegenstand isoliert sind.If therefore a fixed point on the fixed area of the cold End is determined, and a particular object using the stationary point cooled the object can be cooled to an extremely low temperature, wherein vibrations are isolated to the object.
