Anordnung zum Anwärmen und/oder Abkühlen eines Mediums Arrangement for heating and / or cooling a medium
Die Erfindung betrifft eine Anordnung zum Anwärmen und/oder Abkühlen eines The invention relates to an arrangement for heating and / or cooling a

Medium, comprising an ambient air heat exchanger, via which the medium is warmed in one or more heat exchanger tubes against ambient air and / or cooled.
Gattungsgemäße Anordnungen zum Anwärmen und/oder Abkühlen eines Medium, die einen Umgebungsluft-Wärmetauscher aufweisen, sind aus dem Stand der Technik hinlänglich bekannt. Sie dienen bei einer Vielzahl von Anwendungsfällen der Generic arrangements for heating and / or cooling a medium comprising an ambient air heat exchanger are well known in the art. They serve in a variety of applications of

Mediums, beispielsweise eines verflüssigten Gases, wie verflüssigter Stickstoff oder verflüssigter Sauerstoff. Da hierbei die Umgebungsluft als Energielieferant dient, stellt diese Art der Anwärmung und/oder Abkühlung eines Mediums die energetisch günstigste Methode dar. Medium, for example, a liquefied gas, such as liquefied nitrogen or liquefied oxygen. Since in this case the ambient air serves as an energy supplier, this type of heating and / or cooling of a medium is the most energetically favorable method.
Die der vorliegenden Erfindung zugrunde liegende Aufgabe sowie die nachfolgend beschriebene Lösung seien im Folgenden anhand der Verwendung einer The object underlying the present invention and the solution described below are described below with reference to the use of a
gattungsgemäßen Anordnung zum Anwärmen und/oder Abkühlen eines Mediums bei einer Wasserstoff-Tankstelle bzw. einem Wasserstoff-Betankungsprozess erläutert. Es sei jedoch betont, dass die nachfolgend beschriebene, erfindungsgemäße Anordnung selbstverständlich auch bei einer Vielzahl weiterer Anwendungsfälle Verwendung finden kann. Wasserstoff-Tankstellen weisen üblicherweise einen Vorratsspeicher für verflüssigten Wasserstoff auf. Der aus diesem Vorratsspeicher abgezogene flüssige Wasserstoff wird mittels einer sog. Kryopumpe auf einen Abgabe- bzw. Zwischenspeicherdruck von bis zu 900 bar verdichtet. Am Ausgang der Kryopumpe weist der verdichtete generic arrangement for heating and / or cooling of a medium at a hydrogen filling station or a hydrogen refueling process explained. It should be emphasized, however, that the arrangement according to the invention described below can of course also be used in a large number of other applications. Hydrogen filling stations usually have a reservoir for liquefied hydrogen. The withdrawn from this storage liquid hydrogen storage is compressed by means of a so-called. Cryo pump to a discharge or intermediate storage pressure of up to 900 bar. At the outlet of the cryopump has the compressed
Wasserstoff eine Temperatur zwischen 50 und 60 K auf. Zum Betanken von Hydrogen has a temperature between 50 and 60 K. For refueling
Wasserstoff-Fahrzeugen muss der verdichtete Wasserstoff jedoch unter einer Hydrogen vehicles, however, must have the compressed hydrogen under one
Temperatur von ca. -40 °C vorliegen. Die erforderliche Anwärmung des verdichteten Wasserstoffs erfolgt bei einem zum Stand der Technik zählenden Verfahren, das bspw. in der nicht vorveröffentlichten deutschen Patentanmeldung 102009019275
beschrieben ist, mittels eines Thermoblocks, der mittels eines Kälte- und/oder Temperature of about -40 ° C are present. The required heating of the compressed hydrogen takes place in a method belonging to the prior art, which, for example, in the unpublished German patent application 102009019275 is described by means of a thermoblock, by means of a cold and / or
Wärmekreislaufes abgekühlt und/oder erwärmt wird. Alternativ hierzu kann der Heat cycle cooled and / or heated. Alternatively, the
Thermoblock auch elektrisch beheizt werden. Die Anwärmung des verdichteten Wasserstoffs mittels eines Umgebungsluft- Wärmetauschers ist bisher nicht in Erwägung gezogen worden, da die am Austritt des Umgebungsluft-Wärmetauschers herrschende Medientemperatur im Wesentlichen von der aktuellen Umgebungstemperatur abhängig ist. Diese Umgebungstemperatur schwankt jedoch innerhalb Europas im Jahresverlauf zwischen ca. -30 und 40 °C. Des Weiteren ist von Nachteil, dass zu Beginn des Wärmeaustauschprozesses ein vergleichsweise guter Wärmeübergang erfolgt, da die Rohrleitungen bzw. die auf ihnen angebrachten Fins noch keine Bereifung aufweisen. Mit zunehmender Dauer des Wärmeaustauschprozesses kommt es jedoch zu einer immer stärker werdenden Bereifung der Rohrleitungen bzw. Fins, woraus eine merkliche Verschlechterung des Wärmeübergangs resultieren kann. Thermoblock also be electrically heated. The heating of the compressed hydrogen by means of an ambient air heat exchanger has not previously been considered, since the prevailing at the outlet of the ambient air heat exchanger fluid temperature is essentially dependent on the current ambient temperature. However, this ambient temperature varies within Europe between -30 and 40 ° C over the course of the year. Furthermore, it is disadvantageous that a comparatively good heat transfer takes place at the beginning of the heat exchange process, since the pipes or the fins mounted on them do not yet have any tires. With increasing duration of the heat exchange process, however, there is an ever increasing tire wear of the pipes or fins, which can result in a significant deterioration of the heat transfer.
Von Nachteil ist ferner, dass Umgebungsluft-Wärmetauscher vergleichsweise viel Platz beanspruchen, da aufgrund der natürlichen Konvektion der Luft über die Rohrleitungen bzw. Fins ein Minimalabstand zwischen den einzelnen Rohrleitungen vorzusehen ist. A further disadvantage is that ambient air heat exchangers require comparatively much space, since due to the natural convection of the air via the pipes or fins a minimum distance between the individual pipes is provided.
Gattungsgemäße Umgebungsluft-Wärmetauscher kommen daher aus den Generic ambient air heat exchangers therefore come from the
vorgenannten Gründen, und da die gewünschte Medien-Austrittstemperatur von ca. -40 °C mit einer Schwankung von maximal 10 °C eingehalten werden muss, bei Wasserstoff-Tankstellen bzw. Wasserstoff-Betankungsprozessen nicht zur aforementioned reasons, and since the desired media outlet temperature of about -40 ° C must be maintained with a maximum fluctuation of 10 ° C, at hydrogen refueling or hydrogen refueling processes not to
Anwendung. Gleiche Überlegungen gelten für eine Vielzahl von weiteren Application. Same considerations apply to a variety of others
Anwendungsfällen, bei denen das Einhalten einer im Wesentlichen konstanten Medien- Austrittstemperatur von Bedeutung ist. Applications in which maintaining a substantially constant media outlet temperature is important.
Aufgabe der vorliegenden Erfindung ist es, eine gattungsgemäße Anordnung zum Anwärmen und/oder Abkühlen eines Mediums anzugeben, die die mit den Object of the present invention is to provide a generic arrangement for heating and / or cooling of a medium, which with the
vorbeschriebenen Verfahrensweisen verbundenen Nachteile vermeidet. avoid the disadvantages associated with the above-described methods.
Zur Lösung dieser Aufgabe wird eine Anordnung zum Anwärmen und/oder Abkühlen eines Mediums, aufweisend einen Umgebungsluft-Wärmetauscher, über den das Medium in einem oder mehreren Wärmetauscherrohren gegen Umgebungsluft
angewärmt und/oder abgekühlt wird, vorgeschlagen, die dadurch gekennzeichnet ist, dass der Umgebungsluft-Wärmetauscher Mittel zum kontrollierten Führen und/oder Anströmen der Umgebungsluft entlang des oder mindestens einem der To solve this problem, an arrangement for heating and / or cooling of a medium, comprising an ambient air heat exchanger, via which the medium in one or more heat exchanger tubes against ambient air warmed and / or cooled, is proposed, which is characterized in that the ambient air heat exchanger means for controlled guiding and / or flow of the ambient air along or at least one of
Wärmetauscherrohre aufweist, wobei diese Mittel derart ausgebildet sind, dass sie eine variable bzw. regelbare Beeinflussung der Strömungsgeschwindigkeit, -richtung und/oder -Intensität der Umgebungsluft ermöglichen. Heat exchanger tubes, which means are designed such that they allow a variable or controllable influence on the flow velocity, direction and / or intensity of the ambient air.
Erfindungsgemäß kann die Intensität des Wärmeübergangs zwischen der According to the invention, the intensity of the heat transfer between the
Umgebungsluft und dem anzuwärmenden und/oder abzukühlenden Medium nunmehr beeinflusst werden, so dass in Abhängigkeit von der gewünschten Erwärmung bzw. Abkühlung der Wärmeübergang - im Vergleich zu einem Wärmeübergang, der ohne Zuhilfenahme der erwähnten Mittel zum kontrollierten Führen und/oder Anströmen der Umgebungsluft erfolgt - verbessert oder verschlechtert wird. Dieses Verbessern bzw. Verschlechtern des Wärmeübergangs ist jedoch mit einem zusätzlichen apparativen Aufwand und damit zusätzlichen Investitions- und Betriebskosten verbunden. Ambient air and the medium to be heated and / or cooled are now influenced so that, depending on the desired heating or cooling, the heat transfer - in comparison to a heat transfer, which takes place without the aid of the mentioned means for controlled guiding and / or flow of ambient air - improved or worsened. However, this improvement or deterioration of the heat transfer is associated with additional equipment and thus additional investment and operating costs.

The arrangement according to the invention for heating and / or cooling a medium and further embodiments thereof are described below with reference to FIG
Figuren 1 und 2 dargestellten Ausführungsbeispieles näher erläutert. Figures 1 and 2 illustrated embodiment explained in more detail.
Hierbei zeigt die Figur 1 eine seitliche Schnittdarstellung durch das 1 shows a side sectional view through the
Ausführungsbeispiel, während die Figur 2 eine Schnittdarstellung entlang der strichpunktiert gezeichneten Linie A - A zeigt. Embodiment, while Figure 2 shows a sectional view along the dash-dotted line A - A shows.
Wie anhand der Figur 1 dargestellt, wird das mittels der erfindungsgemäßen As shown by the figure 1, the means of the invention
Anordnung abzukühlende und/oder anzuwärmende Medium über Leitung 1 dem Umgebungsluft-Wärmetauscher zugeführt. Dieser ist in Form mäanderförmig angeordneter Wärmetauscherrohre 2 ausgebildet. Durch diese wird das Medium durch den Umgebungsluft-Wärmetauscher geführt, bevor es über Leitung 3 aus der erfindungsgemäßen Anordnung abgezogen wird. In der Praxis wird üblicherweise eine Vielzahl von Wärmetauscherrohren 2 vorgesehen, wie dies anhand der Figur 2 dargestellt ist. Grundsätzlich kann die erfindungsgemäße Anordnung bzw. der Umgebungsluft-Wärmetauscher jedoch auch nur ein einziges Wärmetauscherrohr aufweisen. Arrangement to be cooled and / or to be heated medium via line 1 to the ambient air heat exchanger. This is in the form of meandering arranged heat exchanger tubes 2. Through this, the medium is passed through the ambient air heat exchanger before it is withdrawn via line 3 from the inventive arrangement. In practice, a plurality of heat exchanger tubes 2 is usually provided, as shown with reference to FIG. In principle, however, the arrangement according to the invention or the ambient air heat exchanger can also have only a single heat exchanger tube.
Insbesondere dann, wenn die erfindungsgemäße Anordnung von einem In particular, when the inventive arrangement of a
hochverdichteten Medium durchströmt wird - bspw. gasförmiger Wasserstoff unter einem Druck von bis zu 900 bar -, bestehen die Wärmetauscherrohre 2 vorzugsweise zumindest teilweise aus einem Edelstahlmaterial. high-pressure medium is flowed through - for example, gaseous hydrogen under a pressure of up to 900 bar -, the heat exchanger tubes 2 are preferably at least partially made of a stainless steel material.
Bei dem in den Figuren dargestellten Ausführungsbeispiel ist der mäanderförmig ausgebildete Bereich der Wärmetauscherrohre 2 nunmehr von einer zylinderförmigen Ummantelung bzw. Außenhülle 4 umgeben. Innerhalb dieser sind mehrere In the exemplary embodiment illustrated in the figures, the meander-shaped region of the heat exchanger tubes 2 is now surrounded by a cylindrical casing or outer casing 4. Within these are several
Luftleitbleche 5 derart angeordnet, dass die Umgebungsluft im Wesentlichen parallel zu den Wärmetauscherrohren 2 strömt. Das Vorsehen der Luftleitbleche 5 dient insbesondere dazu, die vorerwähnten störenden Einflüsse im Falle zu gering
beabstandeter Wärmetauscherrohre 2 zu vermeiden und eine individuelle Regelung der Luftströmung entlang der Wärmetauscherrohre 2 zu ermöglichen. Air baffles 5 arranged such that the ambient air flows substantially parallel to the heat exchanger tubes 2. The provision of the air baffles 5 serves in particular to the aforementioned disturbing influences in case too low to avoid spaced heat exchanger tubes 2 and to allow individual control of the air flow along the heat exchanger tubes 2.
Wie anhand der die Luftströmung darstellenden Pfeile gezeigt, werden die von der Außenhülle 4 sowie den Luftleitblechen 5 gebildeten Kanäle von der Umgebungsluft vorzugsweise von oben nach unten durchströmt. Mittels wenigstens eines Lüfters bzw. Ventilators V, der vorzugsweise von einem regelbaren Elektro-Motor M angetrieben wird, kann die Stärke der Luftströmung innerhalb der Außenhülle 4 bzw. der durch die Luftleitbleche 5 gebildeten Kanäle variiert werden. Alternativ zu dem in der Figur 1 dargestellten Ausführungsbeispiel können auch mehrere, vorzugsweise den einzelnen Kanälen zugeordnete Lüfter vorgesehen werden. Zusätzlich oder alternativ können alle oder einzelne der durch die Luftleitbleche 5 gebildeten Kanäle mittels Klappen 8 teilweise und/oder vollständig verschlossen werden. Mittels des bzw. der Lüfter V kann darüber hinaus - zumindest zeitweilig - eine Strömungsgeschwindigkeit eingestellt werden, die es ermöglicht, dass die an den Wärmetauscherrohren 2 bzw. deren Fins anhaftenden Ausfrierungen von der As shown by the arrows showing the air flow, the channels formed by the outer shell 4 and the baffles 5 are preferably flowed through from the ambient air from top to bottom. By means of at least one fan or fan V, which is preferably driven by a controllable electric motor M, the strength of the air flow within the outer shell 4 and the channels formed by the baffles 5 can be varied. As an alternative to the exemplary embodiment illustrated in FIG. 1, it is also possible to provide a plurality of fans, preferably associated with the individual channels. Additionally or alternatively, all or some of the channels formed by the air baffles 5 can be partially and / or completely closed by means of flaps 8. By means of the or the fan V can also - at least temporarily - a flow rate can be adjusted, which allows that adhering to the heat exchanger tubes 2 and their fins frostbite of the
Luftströmung abgelöst und mitgenommen werden. Auf diese Weise kann ein Air flow detached and taken away. This way you can
Selbstreinigungseffekt der Wärmetauscherrohre 2 bzw. Fins realisiert werden. Self-cleaning effect of the heat exchanger tubes 2 and Fins be realized.

Anordnung wird die entlang der Wärmetauscherrohre 2 geführte Umgebungsluft im unteren Bereich 6 der bzw. unterhalb der Außenhülle 4 nach außen geführt und über einen Ringkanal - dieser wird durch eine weitere zylinderförmige Ummantelung 7, die die erstgenannte zylinderförmige Ummantelung 4 umgibt, gebildet - nach oben abgezogen. Diese Ausführung dient dazu, die sehr kalte Umgebungsluft, die eine Nebelbildung verursachen kann, nicht ungehindert abströmen zu lassen, da dies u. U. zu einer Sichtbehinderung und damit Gefährdung von in der Nähe stehenden Arrangement, the guided along the heat exchanger tubes 2 ambient air in the lower portion 6 of the outer shell 4 and out to the outside and via an annular channel - this is through a further cylindrical shell 7, which surrounds the first-mentioned cylindrical shell 4, formed - deducted upwards , This design serves to prevent the very cold ambient air, which can cause fogging, to flow unhindered, since this u. U. to a visual obstruction and thus endangerment of standing nearby
Personen führen kann. Der kalte Luftstrom wird daher mittels entsprechender Persons can lead. The cold air flow is therefore by means of appropriate
Führungsbleche um 180 Grad umgelenkt und am oberen Ende der zylinderförmigen Ummantelung 7 in sicherer Höhe an die Umgebung abgegeben. Guide plates deflected by 180 degrees and discharged at the upper end of the cylindrical casing 7 at a safe height to the environment.

Umgebungsluftstromes vorgesehen sind.
