Abstract

Die Erfindung betrifft einen Kaltkopf für Gaskältemaschinen mit einer Leistung zwischen 10 W und einigen Kilowatt Kälteleistung für die Erzeugung von Temperaturen im Bereich von 80 K (einstufig) und 20 K (zweistufig) nach dem Pulse-Tube-Prinzip. Der Pulse-Tube-Kaltkopf zeichnet sich dadurch aus, dass der warme Wärmetauscher 2 ein Rohr ist, dessen Querschnitt größer ist als der Querschnitt des Pulsrohrs 1 und dass sich zwischen dem warmen Wärmetauscher 2 und dem Reservoir eine zweistufige Inertance-Tube anschließt, die aus einem Trägheitsrohr 3, das möglichst geringe Reibungsverluste verursacht, und einem anschließenden Reibungsrohr mit einem im Vergleich zum Trägheitsrohr 4 geringerem Querschnitt besteht, wobei das Trägheitsrohr 3 mit dem warmen Wärmetauscher 2 und das Reibungsrohr 4 mit dem Reservoir verbunden ist.
