Description
Die Erfindung betrifft eine Tankvorrichtung zur Temperaturdruckentlastung eines Brennstoffzellentanks, insbesondere zur Speicherung von Wasserstoff, beispielsweise zur Anwendung in Fahrzeugen mit Brennstoffzellenantrieb.The invention relates to a tank device for relieving the temperature of a fuel cell tank, in particular for storing hydrogen, for example for use in vehicles with fuel cell drives.
Stand der TechnikState of the art
Die
Die Sicherheitsvorrichtungen für solch eine Einrichtung wie in
Für diese Sicherheitsvorkehrungen ist eine Vielzahl von Ventilen notwendig, wodurch die Komplexität des gesamten Gasspeichersystems sowie dessen Kosten erhöht werden. Weiterhin muss je nach Position des Sicherungsventils sichergestellt sein, dass dieses auch auslöst, wenn sich der Brandherd nicht in der Nähe des Sicherungsventils befindet, um einer möglichen Explosion des Gasspeichersystems vorzubeugen.A large number of valves are necessary for these safety precautions, which increases the complexity of the entire gas storage system and its costs. Furthermore, depending on the position of the safety valve, it must be ensured that it is triggered even if the source of the fire is not in the vicinity of the safety valve in order to prevent a possible explosion of the gas storage system.
Vorteile der ErfindungAdvantages of the invention
Die erfindungsgemäße Tankvorrichtung mit den kennzeichnenden Merkmalen des Anspruchs 1 weist demgegenüber den Vorteil auf, dass in einfacher und effizienter Weise und bei gleichzeitiger Gewährleistung aller Sicherheitsmaßnahmen der Wärmetransport in der Tankvorrichtung verbessert wird, um einen optimalen Einsatz des Sicherungsventils zu gewährleisten.The tank device according to the invention with the characterizing features of claim 1 has the advantage that the heat transport in the tank device is improved in a simple and efficient manner while ensuring all safety measures in order to ensure optimal use of the safety valve.
Dazu umfasst die Tankvorrichtung zur Temperaturdruckentlastung eines Brennstoffzellentanks mindestens zwei Tankbehälter und eine mit den Tankbehältern verbindbare Zufuhrleitung. Jeder Tankbehälter weist an einem Ende mindestens ein Absperrventil auf, welches Absperrventil zwischen dem jeweiligen Tankbehälter und der Zufuhrleitung angeordnet ist. Außerdem ist an einem anderen Ende des Tankbehälters mindestens ein Sicherungsventil angeordnet. Darüber hinaus ist zwischen den mindestens zwei Tankbehältern ein Zwischenraum ausgebildet, in welchem Zwischenraum mindestens eine Heizröhre angeordnet ist.For this purpose, the tank device for relieving the temperature of a fuel cell tank comprises at least two tank containers and a supply line that can be connected to the tank containers. Each tank container has at least one shut-off valve at one end, which shut-off valve is arranged between the respective tank container and the supply line. In addition, at least one safety valve is arranged at another end of the tank container. In addition, an intermediate space is formed between the at least two tank containers, in which intermediate space at least one heating tube is arranged.
Dadurch ist sichergestellt, dass das Sicherungsventil auch auslöst, wenn sich der Brandherd bzw. der Wärmeeintrag weiter entfernt von dem Sicherungsventil befindet. Durch die Heizröhren wird ein schneller Wärmetransport zu dem Sicherungsventil gewährleistet und so eine sichere Funktionsweise der Tankvorrichtung erzielt.This ensures that the safety valve is also triggered if the source of the fire or the heat input is further away from the safety valve. The heating tubes ensure rapid heat transport to the safety valve and thus a safe functioning of the tank device is achieved.
In erster vorteilhafter Weiterbildung ist es vorgesehen, dass die mindestens eine Heizröhre im Querschnitt rechteckig ausgebildet ist. So können die Heizröhren bauraumoptimiert in die Tankvorrichtung integriert werden.In a first advantageous development, it is provided that the at least one heating tube is rectangular in cross section. In this way, the heating tubes can be integrated into the tank device in a space-optimized manner.
In weiterer Ausgestaltung der Erfindung ist es vorteilhaft vorgesehen, dass die mindestens eine Heizröhre mit einem der mindestens zwei Tankbehältern fest verbunden ist. So ist eine einfache und bauraumoptimierte Integration in die Tankvorrichtung möglich.In a further embodiment of the invention, it is advantageously provided that the at least one heating tube is firmly connected to one of the at least two tank containers. This enables simple and space-optimized integration into the tank device.
In weiterer Ausgestaltung der Erfindung ist es vorteilhaft vorgesehen, dass die mindestens eine Heizröhre mit einer Flüssigkeit wie Wasser oder Ammoniak oder einem Gas, beispielsweise Luft, gefüllt ist und ein hermetisch abgeriegeltes System darstellt. So kann in einfacher Weise ein Wärmetransport innerhalb der Heizröhre mittels Verdampfungswärme der Flüssigkeit realisiert werden und dient so als wichtiger Sicherheitsfaktor für eine ordentliche Funktionsweise und ein bewährtes Auslösen des Sicherungsventils.In a further embodiment of the invention, it is advantageously provided that the at least one heating tube is filled with a liquid such as water or ammonia or a gas, for example air, and represents a hermetically sealed system. In this way, heat can be transported within the heating tube in a simple manner by means of the evaporation heat of the liquid and thus serves as an important safety factor for proper functioning and reliable triggering of the safety valve.
In vorteilhafter Weiterbildung ist es vorgesehen, dass die mindestens zwei Tankbehälter aus Stahl gefertigt sind. So wird in einfacher Weise eine Kostenersparnis erzielt.In an advantageous further development it is provided that the at least two tank containers are made of steel. In this way, a cost saving is achieved in a simple manner.
In weiterer Ausgestaltung der Erfindung ist es vorteilhaft vorgesehen, dass in der Zufuhrleitung mindestens ein weiteres Ventil angeordnet ist, durch welches die mindestens zwei Tankbehälter mit einem Anodenbereich eines Brennstoffzellensystems verbindbar sind.In a further embodiment of the invention, it is advantageously provided that at least one further valve is arranged in the supply line through which the at least two tank containers can be connected to an anode region of a fuel cell system.
In vorteilhafter Weiterbildung ist es vorgesehen, dass jeder Tankbehälter an dem anderen Ende das Sicherungsventil aufweist, welches andere Ende des Tankbehälters über das Sicherungsventil und über eine Verbindungsleitung mit einer Ablassleitung verbunden ist.In an advantageous development, it is provided that each tank container has the safety valve at the other end, which other end of the tank container is connected to a drain line via the safety valve and via a connecting line.
In weiterer Ausgestaltung der Erfindung ist es vorteilhaft vorgesehen, dass jeder Tankbehälter an dem anderen Ende über eine Verbindungsleitung mit einer Ablassleitung verbunden ist, in welcher Ablassleitung das Sicherungsventil angeordnet ist. So kann in platzsparender Weise ein gemeinsames Sicherungsventil verwendet werden.In a further embodiment of the invention, it is advantageously provided that each tank container is connected at the other end via a connecting line to a drain line, in which drain line the safety valve is arranged. A common safety valve can thus be used in a space-saving manner.
Die beschriebene Tankvorrichtung eignet sich vorzugsweise in einer Brennstoffzellenanordnung zur Speicherung von Wasserstoff für den Betrieb einer Brennstoffzelle.The tank device described is preferably suitable in a fuel cell arrangement for storing hydrogen for the operation of a fuel cell.
In vorteilhaften Verwendungen kann die Tankvorrichtung in Fahrzeugen mit einem Brennstoffzellenantrieb verwendet werden.In advantageous uses, the tank device can be used in vehicles with a fuel cell drive.
