Description

Die Erfindung betrifft eine Tankvorrichtung zur Speicherung von verdichteten Fluiden für ein Fahrzeug mit Brennstoffzellenantrieb.The invention relates to a tank device for storing compressed fluids for a vehicle with a fuel cell drive.

Stand der TechnikState of the art

Gasspeichersysteme für Fahrzeuge, insbesondere für Drücke bis zu 700 bar, die bevorzugt in Kraftfahrzeugen zur Speicherung von Wasserstoff zur Versorgung einer Brennstoffzellenanordnung eingesetzt werden, sind aus dem allgemeinen Stand der Technik bekannt. Sie weisen einen mehrteiligen Aufbau auf mit einer Innenhülle und einer Außenhülle, wobei die Außenhülle aus faserverstärktem Kunststoff hergestellt ist, um den hohen Gasdruck standzuhalten. Diese sind daher mit hohen Herstellungskosten verbunden.Gas storage systems for vehicles, in particular for pressures of up to 700 bar, which are preferably used in motor vehicles for storing hydrogen to supply a fuel cell arrangement, are known from the general prior art. They have a multi-part structure with an inner shell and an outer shell, the outer shell being made of fiber-reinforced plastic in order to withstand the high gas pressure. These are therefore associated with high manufacturing costs.

Die nicht vorveröffentlichte DE 10 2018 201 055 A1 beschreibt ein solches Gasspeichersystem mit mindestens zwei Speichereinheiten, welche die Speicherung eines gasförmigen Brennstoffs, insbesondere Wasserstoff, Methan oder Erdgas, unter einem verhältnismäßig hohen Innendruck von beispielsweise bis zu 700 bar ermöglicht. Dabei weisen die Speichereinheiten jeweils ein Steuerventil auf, mittels welchem die Speichereinheit zugeschaltet oder abgeschaltet werden kann. Die Speichereinheiten sind über ein Leitungssystem miteinander und mit einer Ausgangsleitung verbunden. Die Ausgangsleitung ist dabei beispielsweise mit einer Verbrauchereinheit wie einer Brennstoffzelleneinheit oder einem Verbrennungsmotor verbunden.The not pre-published DE 10 2018 201 055 A1 describes such a gas storage system with at least two storage units, which enables the storage of a gaseous fuel, in particular hydrogen, methane or natural gas, under a relatively high internal pressure of for example up to 700 bar. The storage units each have a control valve by means of which the storage unit can be switched on or off. The storage units are connected to one another and to an output line via a line system. The output line is connected, for example, to a consumer unit such as a fuel cell unit or an internal combustion engine.

Solche Gasspeichersysteme sind jedoch aufgrund ihrer Größe auf angepasste Karosseriekonstruktionen mit entsprechend großen freien Einbauräumen angewiesen. Selbst bei einer kompakten Anordnung der Speichereinheiten ergeben sich Räume zwischen den Speichereinheiten, welche nicht verwendet werden können.However, due to their size, such gas storage systems are dependent on adapted body designs with correspondingly large free installation spaces. Even with a compact arrangement of the storage units, there are spaces between the storage units which cannot be used.

Es besteht daher der Bedarf nach kostengünstigen Gasspeichersystemen, die einfach herzustellen und an den zur Verfügung stehenden Bauraum effizient anpassbar sind.There is therefore a need for inexpensive gas storage systems that are easy to manufacture and can be efficiently adapted to the available installation space.

Vorteile der ErfindungAdvantages of the invention

Die erfindungsgemäße Tankvorrichtung mit den kennzeichnenden Merkmalen des Anspruchs 1 weist demgegenüber den Vorteil auf, einen in einem begrenzten Bauraum vorhandenen Platz optimal für Gasspeichersysteme unter hohem Druck, wie beispielsweise Wasserstoff oder Erdgas, zu nutzen.The tank device according to the invention with the characterizing features of claim 1 has the advantage of optimally utilizing space available in a limited installation space for gas storage systems under high pressure, such as hydrogen or natural gas.

Dazu weist die Tankvorrichtung zur Speicherung von verdichteten Fluiden und zur Anwendung in Fahrzeugen mit Brennstoffzellenantrieb mindestens zwei Tankkammern auf, welche mindestens zwei Tankkammern mittels Endplatten abgeschlossen sind und so die Tankvorrichtung ausbilden. Die Tankvorrichtung weist weiterhin einen wabenförmigen Querschnitt auf, wobei jede Tankkammer jeweils eine Außenwand aufweist, wobei jeweils ein Abschnitt der Außenwand der mindestens zwei Tankkammern die Gesamtaußenwand der Tankvorrichtung ausbildet und dieser Abschnitt jeweils kreisförmig ausgebildet ist.For this purpose, the tank device for storing compressed fluids and for use in vehicles with fuel cell drives has at least two tank chambers, which at least two tank chambers are closed off by means of end plates and thus form the tank device. The tank device also has a honeycomb cross-section, each tank chamber each having an outer wall, a portion of the outer wall of the at least two tank chambers forming the overall outer wall of the tank device and this portion being circular.

So ist in einfacher Weise eine Tankvorrichtung herstellbar, welche eine effiziente Verwendung des für die Tankvorrichtung verfügbaren Platzes innerhalb von Fahrzeugen mit Brennstoffzellenantrieb erzielt. Außerdem stellt die kreisförmige Ausprägung der Abschnitte der Außenwände der Tankkammern eine gleichmäßige Belastung durch den Druck des gespeicherten Gases sicher, so dass mögliche Druck-Beschädigungen so minimiert werden können.In this way, a tank device can be produced in a simple manner which achieves efficient use of the space available for the tank device within vehicles with fuel cell drives. In addition, the circular shape of the sections of the outer walls of the tank chambers ensures an even load from the pressure of the stored gas, so that possible pressure damage can be minimized.

In erster vorteilhafter Weiterbildung ist es vorgesehen, dass eine feste Verbindung zwischen den mindestens zwei Tankkammern durch eine Verspannung mittels Endplatten und/oder Verspannungsstäben herstellbar ist.In a first advantageous development it is provided that a fixed connection between the at least two tank chambers can be established by bracing by means of end plates and / or bracing rods.

In weiterer Ausgestaltung der Erfindung ist es vorteilhaft vorgesehen, dass jede Tankkammer einen wabenförmigen Querschnitt mit einem Tankinnenraum aufweist, welcher Tankinnenraum zu den Enden hin verjüngt ist. Vorteilhafterweise mündet der Tankinnenraum jeder Tankkammer in einen Kanal, welcher Kanal in den Endplatten ausgebildet ist und vorteilhafterweise sind die Endplatten mittels Schraubelementen mit den mindestens zwei Tankkammern fest verbunden. Durch den veränderlichen Querschnitt ist so in konstruktiv einfacher Weise eine feste Verbindung der Tankkammern mittels Schraubelementen möglich.In a further embodiment of the invention, it is advantageously provided that each tank chamber has a honeycomb-shaped cross section with a tank interior, which tank interior is tapered towards the ends. The tank interior of each tank chamber advantageously opens into a channel, which channel is formed in the end plates, and the end plates are advantageously firmly connected to the at least two tank chambers by means of screw elements. Due to the variable cross-section, a fixed connection of the tank chambers by means of screw elements is possible in a structurally simple manner.

Die beschriebene Tankvorrichtung zur Speicherung von verdichteten Fluiden eignet sich vorzugsweise in einer Brennstoffzellenanordnung zur Speicherung von Wasserstoff für den Betrieb einer Brennstoffzelle.The tank device described for storing compressed fluids is preferably suitable in a fuel cell arrangement for storing hydrogen for operating a fuel cell.

Die beschriebene Tankvorrichtung zur Speicherung von verdichteten Fluiden eignet sich vorzugsweise in einem Fahrzeug mit einem Antrieb mit gasförmigen Kraftstoffen.The tank device described for storing compressed fluids is preferably suitable in a vehicle with a drive with gaseous fuels.

Beschreibung des AusführungsbeispielsDescription of the embodiment

1 zeigt ein erstes Ausführungsbeispiel einer erfindungsgemäßen Tankvorrichtung 1 beispielsweise zur Anwendung in Fahrzeugen mit Brennstoffzellenantrieb im Querschnitt. 1 shows a first embodiment of a tank device according to the invention 1 for example for use in vehicles with fuel cell drives in cross section.

Die Tankvorrichtung 1 weist einen im Wesentlichen wabenförmigen Querschnitt auf und umfasst mehrere Tankkammern 10, 10'. Jede Tankkammer 10,10' weist eine Außenwand 12, 12' auf, wobei jeweils ein Abschnitt 14 der Außenwand 12, 12' der Tankkammern 10, 10' die Gesamtaußenwand 13 der Tankvorrichtung 1 ausbilden. Dieser Abschnitt 14 ist jeweils kreisförmig ausgebildet.The tank device 1 has a substantially honeycomb cross-section and comprises a plurality of tank chambers 10 , 10 ' . Every tank chamber 10 , 10 'has an outer wall 12 , 12 ' on, each with a section 14th the outer wall 12 , 12 ' the tank compartments 10 , 10 ' the total outer wall 13th the tank device 1 form. this section 14th is each circular.

Abschnitte der Außenwand 12 der Tankkammern 10 sind als eine innenliegende Wand 11 ausgebildet und grenzen jeweils an eine innenliegende Wand 11' einer anderen Tankkammer 10', ausgebildet aus Abschnitten der Außenwand 12' der Tankkammern 10', und können beispielsweise wie in 1 gezeigt, geradlinig ausgebildet sein.Sections of the outer wall 12 the tank compartments 10 are as an interior wall 11 formed and each border on an interior wall 11 ' another tank chamber 10 ' , formed from sections of the outer wall 12 ' the tank compartments 10 ' , and can, for example, as in 1 shown, be straight.

Die Tankkammern 10, 10' weisen einen wabenförmigen Querschnitt auf, wobei die Tankkammern 10, 10' einen Tankinnenraum 2 umfassen.The tank chambers 10 , 10 ' have a honeycomb cross-section, the tank chambers 10 , 10 ' a tank interior 2 include.

Weiterhin sind die Tankkammern 10, 10' mittels Endplatten 4 abgeschlossen und mittels Schraubelementen 3 fest miteinander verbunden, wie in 2a und 2b gezeigt. So kann die längliche Wabenstruktur der gesamten Tankvorrichtung 1 abgeschlossen werden.There are also the tank chambers 10 , 10 ' by means of end plates 4th completed and by means of screw elements 3 firmly connected, as in 2a and 2 B shown. So the elongated honeycomb structure of the entire tank device 1 be completed.

2a zeigt Tankkammern 10, 10', deren Tankinnenraum 2 zu den Enden hin verjüngt ist. Diese Verjüngung mündet weiterhin in einen Kanal 6, welcher in den Endplatten 4 ausgebildet ist. So ist der Tankinnenraum 2 jeder Tankkammer 10, 10' über den Kanal 6 verbunden, wodurch beispielsweise eine Befüllung der Tankinnenräume 2 mit gasförmigem Medium über den Kanal 6 erfolgt. 2a shows tank chambers 10 , 10 ' , their tank interior 2 is tapered towards the ends. This taper continues to flow into a canal 6th , which in the end plates 4th is trained. So is the tank interior 2 each tank chamber 10 , 10 ' across the canal 6th connected, whereby for example a filling of the tank interior 2 with gaseous medium via the channel 6th he follows.

Darüber hinaus ist eine feste Verspannung der einzelnen Tankkammern 10, 10' ebenfalls mittels Verspannungsstäben 7, wie in 2b gezeigt, herstellbar.
