Abstract
Description
Die Erfindung betrifft einen Druckbehälter aus Kunststoff gemäß dem Oberbegriff des Patentanspruchs 1. Die Erfindung betrifft auch geeignete Verfahren zur Herstellung eines derartigen Druckbehälters gemäß den jeweiligen Merkmalskombinationen der Ansprüche 13, 14 und 15.The invention relates to a pressure vessel made of plastic according to the preamble of
Es ist allgemein bekannt, flüssige und gasförmige Medien mittels Behältern respektive Tanks zu lagern und/oder zu transportieren, wobei besagte Behälter bzw. Tanks in Abhängigkeit von den Eigenschaften des zu lagernden und/oder zu transportierenden flüssigen oder gasförmigen Mediums, den Lager- und/oder Transportbedingungen an sich und/oder anderen an sich bekannten Randbedingungen unterschiedlichste Ausführungsformen aufweisen können.It is generally known to store and / or transport liquid and gaseous media by means of containers or tanks, said containers or tanks, depending on the properties of the liquid or gaseous medium to be stored and / or transported, the storage and / or or transport conditions per se and / or other per se known boundary conditions may have very different embodiments.
So ist aus der
Aufgabe der Erfindung ist es, einen im Hinblick auf den einleitend beschriebenen Stand der Technik alternativen Druckbehälter aus Kunststoff zu schaffen, der seinerseits mittels zumindest eines auf der Außenkontur desselben angeordneten Versteifungselementes gegen nach außen gerichtete kritische Deformationen seiner Behälterwandung infolge erhöhten Innendruckes versteift und einfach in der Herstellung und kostengünstig ist, sowie Innendrücken von 300 bar und mehr standhält. Aufgabe der Erfindung ist es auch, geeignete Verfahren zur Herstellung eines derart versteiften Druckbehälters anzugeben.The object of the invention is to provide an alternative to the initially described prior art pressure vessel made of plastic, in turn stiffened by means of at least one of the outer contour of the same arranged stiffening element against outward critical deformation of its container wall due to increased internal pressure and easy in the Manufacture and is cost-effective, as well as withstand internal pressures of 300 bar and more. The object of the invention is also to provide suitable methods for producing a stiffened pressure vessel of this type.
Ausgehend von einem Druckbehälter aus Kunststoff, der seinerseits mittels zumindest eines auf der Außenkontur desselben angeordneten Versteifungselementes gegen nach außen gerichtete kritische Deformationen seiner Druckbehälterwandung infolge erhöhten Innendruckes versteift ist, wird die gestellte Aufgabe dadurch gelöst, dass das zumindest eine Versteifungselement durch eine den Druckbehälter in ausgewählten Bereichen desselben, die infolge erhöhten Innendruckes zu einer Deformation nach außen neigen, umschlingende geschlossene Rahmenstruktur gebildet ist.Starting from a pressure vessel made of plastic, which in turn is stiffened by means of at least one arranged on the outer contour of the stiffening element against outward critical deformation of its pressure vessel wall due to increased internal pressure, the object is achieved in that the at least one stiffening element by a pressure vessel in selected Areas thereof, which tend to deform outward due to increased internal pressure, looped closed frame structure is formed.
Aufgrund der geschlossenen Rahmenstruktur der Versteifungselemente kann ein erhöhter Widerstand gegen eine etwaige nach außen ausweichende Behälterwandung aus Kunststoff infolge erhöhten Innendruckes aufgebracht werden, welches vorteilhaft die Verwendung des Druckbehälters zur Aufnahme von flüssigen oder gasförmigen Medien gestattet, die ihrerseits mit Innendrücken bis 300 bar und mehr gelagert werden, und welches insbesondere bei der Verwendung des Druckbehälters zur Aufnahme von LPG (LPG = Liquified Petroleum Gas) und CNG (CNG = Compressed Natural Gas) angezeigt ist.Due to the closed frame structure of the stiffening an increased resistance to any evasive outwardly plastic container wall due to increased internal pressure can be applied, which advantageously allows the use of the pressure vessel for receiving liquid or gaseous media, which in turn stored with internal pressures up to 300 bar and more and which is indicated in particular when using the pressure vessel for holding LPG (LPG) and CNG (CNG = compressed natural gas).
Die Unteransprüche beschreiben bevorzugte Weiterbildungen oder Ausgestaltungen der Erfindung. The subclaims describe preferred developments or refinements of the invention.
So können die besagten ausgewählten Bereiche des Druckbehälters, die infolge erhöhten Innendruckes zu einer Deformation nach außen neigen, vorteilhaft empirisch im Rahmen von Versuchen und/oder rechnerisch ermittelt werden. Weiter vorteilhaft kann die zumindest eine Rahmenstruktur durch einen Rohr- und/oder Profilrahmen gebildet sein, der sich einfach und kostengünstig herstellen und an beliebige Behältergrößen und -formen anpassen lässt. Des Weiteren kann es angezeigt sein, die zumindest eine Rahmenstruktur zumindest abschnittsweise in einer oder mehreren Einschnürungen der Druckbehälterwandung anzuordnen, wodurch vorteilhaft ein zumindest abschnittsweise realisierter Formschluss zwischen der Rahmenstruktur und der Druckbehälterwandung mit einer Erhöhung der Eigensteifigkeit des Kunststoff-Druckbehälters kombiniert ist. Besonders vorteilhaft können zwei oder mehr Rahmenstrukturen direkt oder über ein oder mehrere Verbindungselemente miteinander starr verbunden sein, wodurch die Erstellung eines Verbundes zwischen besagten Rahmenstrukturen und dem Kunststoff-Behälter erleichtert bzw. vereinfacht ist und die Steifigkeit des realisierten Zusammenbaus noch weiter erhöht ist. Die zumindest eine Rahmenstruktur kann aus Metall, einem faserverstärkten Kunststoff oder jedwedem anderen geeigneten Werkstoff bestehen. Ferner kann die zumindest eine Rahmenstruktur bereits Mittel zur Befestigung des Verbundes aus dem Druckbehälter und der zumindest einen Rahmenstruktur an einer besagten Verbund tragenden Struktur ausbilden, wodurch die Montage desselben an oder in der tragenden Struktur erleichtert ist. So kann die besagten Verbund tragende Struktur beispielsweise durch eine Karosseriestruktur eines Fahrzeugs, insbesondere Kraftfahrzeugs, gebildet sein. Was den Druckbehälter an sich anbelangt, kann dieser bevorzugt aus einem thermoplastischen Kunststoff bestehen, welcher gestattet, den Druckbehälter, der wie bereits oben angedeutet, beispielsweise als Kraftstoffbehälter zur Aufnahme von LPG oder CNG Verwendung finden kann, nach einem an sich bekannten Blasformverfahren herzustellen.Thus, the said selected areas of the pressure vessel, which tend to a deformation due to increased internal pressure to the outside, advantageously empirically determined in the context of experiments and / or computationally. Further advantageously, the at least one frame structure may be formed by a tubular and / or profile frame, which can be easily and inexpensively manufactured and adapted to any container sizes and shapes. Furthermore, it may be appropriate to arrange the at least one frame structure at least in sections in one or more constrictions of the pressure vessel wall, which advantageously combines an at least partially realized positive connection between the frame structure and the pressure vessel wall with an increase in inherent rigidity of the plastic pressure vessel. Particularly advantageously, two or more frame structures can be rigidly connected to one another directly or via one or more connecting elements, whereby the creation of a bond between said frame structures and the plastic container is simplified or simplified and the rigidity of the realized assembly is increased even further. The at least one frame structure may be made of metal, a fiber reinforced plastic, or any other suitable material. Furthermore, the at least one frame structure can already form means for fastening the composite from the pressure vessel and the at least one frame structure to a said composite-bearing structure, whereby the assembly of the same is facilitated on or in the supporting structure. Thus, the said composite-bearing structure may be formed, for example, by a body structure of a vehicle, in particular a motor vehicle. As far as the pressure vessel itself is concerned, it can preferably consist of a thermoplastic which allows the pressure vessel, which can be used, for example, as a fuel tank for holding LPG or CNG, as already indicated above, to be produced by a blow-molding process known per se.
Die Erfindung betrifft auch ein Kraftfahrzeug mit einem Druckbehälter der erfindungsgemäßen Art.The invention also relates to a motor vehicle with a pressure vessel of the type according to the invention.
Ein einfach und kostengünstig umsetzbares und demgemäß bevorzugtes Verfahren zur Herstellung eines Druckbehälters der oben beschriebenen Art zeichnet sich durch folgende Verfahrensschritte aus:
- – Bereitstellung zweier zunächst separat ausgebildeter Rahmenstruktur-Ebenen, die ihrerseits jeweils zumindest aus einem oder aus mehreren, ggf. untereinander starr verbundenen offenen Rahmenstrukturelementen bestehen, wobei besagte Rahmenstruktur-Ebenen untereinander zu einer oder mehreren geschlossenen Rahmenstrukturen fest verbindbar sind,
- – Einlegen der Rahmenstrukturelemente besagter Rahmenstruktur-Ebenen in Werkzeughälften eines Blasformwerkzeuges, welches als Negativform weitestgehend die Außenkontur des herzustellenden Druckbehälters nachbildet,
- – Einbringen eines Vorformlings in Form einer Kunststoffblase aus einem thermoplastischen Kunststoff in den von den Rahmenstrukturelementen umschlossenen Raum,
- – Aufblasen der Kunststoffblase unter Wärmeeinwirkung, wobei die Kunststoffblase sich an die Kontur der Rahmenstrukturelemente sowie an die Innenkontur des Blaswerkzeugs anschmiegt und nach Abkühlung erstarrt,
- – kraft-, form- und/oder stoffschlüssige Verbindung der Rahmenstrukturelemente besagter Rahmenstruktur-Ebenen zu geschlossenen Rahmenstrukturen.
- Provision of two initially separately formed frame structure levels, each of which in turn consists of at least one or more, optionally rigidly interconnected open frame structure elements, wherein said frame structure levels are permanently connectable to one another or more closed frame structures,
- Inserting the frame structure elements of said frame structure planes into tool halves of a blow molding tool, which as a negative mold simulates as far as possible the outer contour of the pressure vessel to be produced,
- - introducing a preform in the form of a plastic bladder made of a thermoplastic material in the space enclosed by the frame structure elements space,
- Inflating the plastic bladder under the effect of heat, wherein the plastic bladder conforms to the contour of the frame structure elements and to the inner contour of the blow mold and solidifies after cooling,
- - Force, shape and / or material connection of the frame structure elements of said frame structure levels to closed frame structures.
