The refrigerant liquefied gases are in the pressure vessels under an operating pressure of approx. 10 to approx. 15 bar.

Bisher bestehen Druckbehälter der betrachteten Art aus Stahl mit der Folge, daß sie ein beträchtliches Gewicht haben. Dies wirkt sich nachteilig beim Transport der Druckbehälter und bei deren Handhabung aus. Außerdem haben Stahlbehälter Nachteile wie Rost, Zunder und sonstige Verunreinigungen im Behälterinneren.So far, pressure vessels of the type under consideration are made of steel, with the result that they to be of considerable weight. This is disadvantageous when transporting the Pressure vessels and their handling. They also have steel tanks Disadvantages such as rust, scale and other contaminants inside the container.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, einen Druckbehälter anzugeben, bei dem diese Nachteile vermieden sind.The present invention is therefore based on the object of a pressure vessel specify where these disadvantages are avoided.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst.This object is achieved according to the invention by the features of patent claim 1 solved.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen gekennzeichnet. Advantageous embodiments of the invention are in the subclaims characterized.

Der erfindungsgemäße Druckbehälter ist aus zwei Behälter-Halbschalen zusammengesetzt, die miteinander verschweißt sind und die aus einer Aluminium-Legierung bestehen, womit der Druckbehälter erheblich leichter als ein Stahlbehälter ist.The pressure vessel according to the invention is made up of two half shells composed, which are welded together and made of an aluminum alloy exist, which makes the pressure vessel considerably lighter than one Steel container is.

Weiter ist vorgesehen, daß die Behälter-Halbschalen eine Wandstärke haben, die je nach Behältergröße nur 4,7 mm bis 5,2 mm beträgt, was ebenfalls zu einer beträchtlichen Gewichtsreduzierung des Druckbehälters führt.It is also provided that the container half-shells have a wall thickness, each depending on the container size is only 4.7 mm to 5.2 mm, which also results in a leads to considerable weight reduction of the pressure vessel.

Die Behälter-Halbschalen werden erfindungsgemäß in einem mehrstufigen Tiefziehverfahren in einem einzigen Arbeitsgang ohne Zwischenglühen hergestellt, wobei ferner vorgesehen ist, daß das Verhältnis von Höhe zu Durchmesser der Halbschalen etwa 1:1 bis 3:1 beträgt. Dieser in einem einzigen Arbeitsgang erfolgende Tiefziehvorgang bringt es mit sich, daß der erfindungsgemäße Druckbehälter kostengünstig herstellbar ist.According to the invention, the container half-shells are produced in a multi-stage deep-drawing process produced in a single operation without intermediate annealing, whereby it is also provided that the ratio of height to diameter of the Half shells is about 1: 1 to 3: 1. This in a single operation deep-drawing process takes place with the fact that the invention Pressure vessel is inexpensive to manufacture.

Dies ist erst recht der Fall, wenn nach einem weiteren Vorschlag der Erfindung die zwei Behälter-Halbschalen, aus denen der Druckbehälter zusammengesetzt wird, eine identische Form haben, so daß nur ein einziges Ziehwerkzeug erforderlich ist.This is even more the case if, according to a further proposal of the invention two half-shells from which the pressure vessel is assembled, have an identical shape so that only one drawing tool is required.

Bei einer Ausführungsform der Erfindung ist vorgesehen, daß die Behälter-Halbschalen jeweils in einem ersten Stufenzug bis zu einer ersten Ziehtiefe, die bevorzugt etwa 50% der endgültigen Ziehtiefe beträgt, mit einem ersten Durchmesser gezogen werden, der größer als der endgültige Durchmesser der fertigen Halbschalen bzw. Behälter ist. In einem unmittelbar anschließenden zweiten Stufenzug werden dann die Halbschalen über die gesamte Ziehtiefe mit dem endgültigen Durchmesser gezogen. Die beiden Stufenzüge werden unmittelbar aufeinanderfolgend in dem Ziehwerkzeug ausgeführt, ohne daß Zwischenprodukte aus dem Ziehwerkzeug entnommen werden müssen. Die Herstellung einer Behälter-Halbschale dauert auf diese Weise nur etwa 15 Sekunden. In one embodiment of the invention it is provided that the container half-shells each in a first step up to a first depth of draw, the preferably about 50% of the final depth of draw, with a first Diameter larger than the final diameter of the finished half-shells or containers. In an immediately following one The second stage then the half shells along with the entire depth of drawing drawn to the final diameter. The two levels are immediate carried out successively in the drawing tool without intermediate products must be removed from the drawing tool. The production of a container half-shell takes only about 15 seconds in this way.

Bei einer besonders bevorzugten Ausführungsform der Erfindung werden die Behälter-Halbschalen in drei aufeinander folgenden Stufenzügen gefertigt. Hiermit läßt sich ein Verhältnis von Höhe zu Durchmesser von bis zu 3:1 erreichen.In a particularly preferred embodiment of the invention, the Container half-shells manufactured in three successive stages. Herewith a ratio of height to diameter of up to 3: 1 can be achieved.

In einer Ausführungsform, die ein Fassungsvermögen von ca. 11 kg Kältemittel hat, hat der Druckbehälter eine Höhe von etwa 470 mm bei einem Durchmesser von etwa 300 mm. Hierbei beträgt die Wandstärke des Druckbehälters ca. 4,7 mm.In one embodiment, which has a capacity of approximately 11 kg of refrigerant, the pressure vessel has a height of about 470 mm with a diameter of about 300 mm. The wall thickness of the pressure vessel is approximately 4.7 mm.

In einer anderen Ausführungsform hat der Druckbehälter eine Höhe von etwa 560 mm bei einem Durchmesser von etwa 300 mm, womit dieser Druckbehälter ein Fassungsvermögen von ca. 14 kg Kältemittel hat. Hierbei beträgt die Wandstärke des Druckbehälters ca. 5,2 mm.In another embodiment, the pressure vessel has a height of approximately 560 mm with a diameter of about 300 mm, making this a pressure vessel Has a capacity of approx. 14 kg of refrigerant.
