für mehrere
in wenigstens einer Reihe benachbart zueinander angeordnete, elektrochemische
Speicherzellen bekannt (
Bekannt ist weiterhin eine Wärmeaustauscherstruktur
für mehrere,
elektrochemische Speicherzellen, die ein Kanalbauteil aufweist,
das zwei parallel zueinander angeordnete Materialstreifen enthält, die
zwischen sich einen Wärmeaustauscherkanal
bilden. Die Materialstreifen haben an die Speicherzellenform angepasste
Ausformungen. Es sind zwei Wärmeaustauscherkanäle zwischen
je zwei Materialstreifen vorhanden. Ein Wär meaustauscherkanal ist an
der Oberseite und der andere an der Unterseite der Speicherzellenreihe
angeordnet. Die Wärmeaustauscherkanäle sind
mit Verteilern verbunden, die an den Längsseiten der in Reihen nebeneinander
angeordneten Speicherzellen angebracht sind (
Der Erfindung liegt das Problem zugrunde, einen elektrochemischen Energiespeicher mit einer Wärmeaustauscherstruktur und mit mehreren, jeweils in wenigstens zwei Reihen benachbart zueinander angeordneten Speicherzellen anzugeben, bei dem in den Speicherzellen unabhängig von ihrer Lage innerhalb der Reihen besonders aneinander angeglichene Temperaturen erreicht werden können.The invention is based on the problem, a electrochemical energy store with a heat exchanger structure and with several, each in at least two rows adjacent to each other to indicate arranged memory cells, in which in the memory cells independently of their position within the rows, especially aligned with each other Temperatures can be reached.
Das Problem wird bei einem Energiespeicher der eingangs beschriebenen Art erfindungsgemäß dadurch gelöst, dass zwischen den Reihen von Speicherzellen ein an den Speicherzellen anliegendes Kanalbauteil vorgesehen ist, das in zwei nebeneinander angeordneten Reihen in Längsrichtung der Reihen von Speicherzellen verlaufende, nebeneinander in jeder der beiden Reihen angeordnete Wärmetauscherkanäle aufweist, dass an den Enden der Reihen von Speicherzellen je ein Vorlaufverteilerkanal und je ein Rücklaufsammelkanal angeordnet ist, dass benachbarte Wärmeaustauscherkanäle in der einen Reihe jeweils an ihren einen Enden mit dem an einem und dem am anderen Ende der Reihe von Speicherzellen angeordneten Vorlaufverteilerkanal für die Einspeisung des Temperiermediums in zueinender entgegengesetzten Strömungsrichtungen in die benachbarten Wärmetauscherkanäle verbunden sind, dass jeder Wärmeaustauscherkanal in der einen Reihe an seinem anderen Ende mit dem Ende des in der anderen Reihe benachbarten Wärmeaustauscherkanals verbunden ist und dass die anderen Enden der Wärmeaustauscherkanäle der anderen Reihe entsprechend ihrer Lage am Ende der Reihe mit dem Rücklaufsammelkanal an dem einen oder dem anderen Ende der Reihen von Speicherzellen verbunden sind. Unter Verbindung der Wärmeaustauscherkanäle untereinander oder mit den Vorlauf- oder Rücklaufsammelkanälen ist hierbei zu verstehen, dass Öffnungen an den Kanälen zum Überleiten des Temperiermediums von einem Kanal zum anderen vorhanden sind. Mit der erfindungsgemäßen Wärmetauscherstruktur wird eine sehr gleichförmige Ableitung der in den einzelnen Speicherzellen erzeugten Wärmemengen erreicht, so dass die Speicherzellen nahezu gleiche Temperaturen aufweisen. Besonders günstig ist die erfindungsgemäße Wärmesaustauscherstruktur bei Energiespeichern mit zahlreichen Reihen von Speicherzellen. Da mit der erfindungsgemäßen Wärmeaustauscherstruktur in den Speicherzellen weitgehend gleiche Temperaturen erzielt werden, ergeben sich auch weitgehend einander angeglichene elektrische Eigenschaften der Speicherzellen, so dass ungleichmäßige Belastungen der Speicherzellen und Verlustwärmen bedeutend vermindert werden. Damit wird ein weniger störanfälliger Betrieb des Energiespeichers erreicht.The problem becomes with an energy storage The type described above solved according to the invention, that between the rows of memory cells on the memory cells adjacent channel component is provided, in two adjacent arranged rows in the longitudinal direction the rows of memory cells running side by side in each having heat exchanger channels arranged in the two rows, that at the ends of the rows of memory cells depending on a flow distribution channel and one return collection channel each is arranged that adjacent heat exchanger channels in the one Row at one end with the one on the other and at the other End of the series of memory cells arranged flow distribution channel for the feed the tempering in zueinender opposite directions of flow are connected in the adjacent heat exchanger channels, that every heat exchanger channel in one row at the other end with the end of the in the another series of adjacent heat exchange channels is connected and that the other ends of the heat exchanger channels of the other row according to their position at the end of the row with the return collection channel connected at one or the other end of the rows of memory cells are. By connecting the heat exchanger channels with each other or with the flow or return collection channels hereby understand that openings at the channels to pass on the Tempering medium from one channel to another are present. With the heat exchanger structure according to the invention becomes a very uniform derivative reaches the heat generated in the individual memory cells, so that the memory cells have nearly the same temperatures. Especially Cheap is the heat exchanger structure according to the invention in energy storage with numerous rows of storage cells. As with the heat exchanger structure according to the invention in the memory cells largely the same temperatures are achieved also result in largely matched electrical properties the memory cells, allowing uneven loads on the memory cells and heat loss be significantly reduced. This will be a less interference-prone operation reached the energy storage.
Zweckmäßigerweise ist an den nach außen gerichteten Seiten der Speicherzellen an den Außenseiten des Energiespeichers jeweils ein Kanalbauteil vorgesehen, dessen den Speicherzellen zugewandte Seite an den Speicherzellen anliegt und dessen den Speicherzellen abgewandte Seite eben ist. Bei dieser Ausführungsform stehen auch die in den äußeren Reihen des Energiespeichers liegenden Speicherzellen in ihrer Längsrichtung beiderseits mit einem Kanalbauteil mit Wärmeaustauscherkanälen in Verbindung. Damit wird auch bei den Speicherzellen in den äußeren Reihen jeweils eine Temperatur erzielt, die derjenigen in den Speicherzellen der inneren Reihen weitgehend angeglichen ist.Appropriately, is to the after directed outside Pages of the memory cells on the outside of the energy storage in each case a channel component is provided, its side facing the memory cells abuts the memory cells and facing away from the memory cells Side is flat. In this embodiment are also in the outer rows the energy storage lying memory cells in their longitudinal direction on both sides with a channel component with heat exchanger channels in connection. This is also at the memory cells in the outer rows each have a temperature achieved that of those in the memory cells of the inner rows largely is aligned.
Bei bevorzugten Ausführungsform sind die Verteilerkanäle für den Vorlauf und die Rücklaufsammelkanäle jeweils neben den Enden der Reihen von Speicherzellen zwischen den beiden äußeren Reihen von Speicherzellen abwechselnd mit den Enden über die Speicherzellen beiderseits vorstehend parallel zueinander angeordnet. Mit dieser Anordnung wird eine kompakte Bauform der Wärmeaustauscherstruktur außerhalb der Räume zwischen den Speicherzellen erreicht.In preferred embodiment are the distribution channels for the Flow and the return collection channels each adjacent the ends of the rows of memory cells between the two outer rows of memory cells alternating with the ends across the memory cells on both sides arranged in parallel to each other. With this arrangement will a compact design of the heat exchanger structure outside of the rooms reached between the memory cells.
Es ist günstig, wenn die Verteilerkanäle für den Vorlauf an den beiden Enden der Speicherzellenreihen an ihren, an einer Seite über die Speicherzellenreihen vorstehenden Enden je mit einem vorgeschalteten Verteilerkanal für den Vorlauf verbunden sind, der nahe an den Enden der Speicherzellenreihen auf einer Seite des Energiespeichers sich zwischen den Speicherzellen der äußeren Reihen erstreckt. Diese Ausführungsform trägt zum kompakten Aufbau der Wärmeaustauscherstruktur bei.It is convenient if the distribution channels for the flow at the two ends of the storage cells rows at their ends protruding on one side across the rows of memory cells are each connected to an upstream distribution channel for the lead, which extends between the memory cells of the outer rows near the ends of the rows of memory cells on one side of the energy storage. This embodiment contributes to the compact construction of the heat exchanger structure.
Vorzugsweise sind die Rücklaufsammelkanäle an den beiden Enden der Speicherzellenreihen auf der anderen Seite des Energiespeichers mit ihren über die Speicherzellen vorstehenden Enden mit einem nachgeschalteten Rücklaufkanal verbunden, der nahe an den Enden der Speicherzellenreihen sich zwischen den Speicherzellen der äußeren Reihen erstreckt. Hierdurch wird ein kompakter Aufbau des Rücklaufteils erreicht, der außerhalb der Räume zwischen den Speicherzellen verläuft.Preferably, the return collection channels are at the both ends of the memory cell rows on the other side of the Energy storage with their over the memory cells projecting ends with a downstream Return channel connected near the ends of the memory cell rows between the memory cells of the outer rows extends. This results in a compact design of the return part reached the outside the spaces between the memory cells runs.
Bei einer weiteren zweckmäßigen Ausführungsform sind die beiden vorgeschalteten Verteilerkanäle für den Vorlauf und die beiden nachgeschalteten Rücklaufsammelkanäle je über eine Rohrleitung mit Ausgängen eines Vorlaufverteilerkopfs bzw. mit Eingängen eines Rücklaufverteilerkopfs verbunden, wobei der Eingang des Vorlaufverteilerkopfs und der Ausgang des Rücklaufverteilerkopfs an eine externe Kühleinrichtung oder an einen Klimaanlagenkompressor angeschlossen sind.In a further advantageous embodiment are the two upstream distribution channels for the flow and the two downstream return collection channels each via a Pipeline with outputs a flow distributor head or with inputs of a return manifold head connected, the input of the flow distributor head and the output the return manifold head to an external cooling device or connected to an air conditioning compressor.
Insbesondere weisen die Kanalbauteile an ihren, den Mänteln von zylindrischen Speicherzellen zugewandten Seiten eine wellenförmige Struktur mit an die Mäntel der Speicherzellen angepassten halbzylindrischen Vertiefungen auf. Mit dieser Ausführungsform wird ein guter Wärmeübergang von den Speicherzellen auf die Kanalbauteile erreicht.In particular, the channel components at their coats of cylindrical memory cells facing sides of a wavy structure with the coats the memory cells adapted semi-cylindrical wells on. With this embodiment will be a good heat transfer reached from the memory cells to the channel components.
Bei Speicherzellen mit elektrisch leitenden Gehäusen sind die Kanalbauteile zweckmäßigerweise aus einem elektrisch isolie renden Material, wobei die Wärmeaustauscherkanäle wellenförmig in der Struktur verlaufen, um das Temperiermedium näher an die Speicherzellenflächen zu bringen, die allerdings aufgrund ihrer metallischen Gehäuse einen besseren Wärmeübergang bewirken als isolierende Gehäuse.In memory cells with electric conductive housings are the channel components expediently from an electrically insulating material, the heat exchanger channels being wavy of the structure extend to the tempering medium closer to the memory cell surfaces bring, however, due to their metallic housing a better Heat transfer cause as insulating housing.
Bei Speicherzellen mit elektrisch isolierenden Gehäusen bestehen die Kanalbauteile vorzugsweise aus Metall, insbesondere Aluminium. Die Wärmeaustauscherkanäle können dann geradlinig in den Kanalbauteilen verlaufen, da das Metall gut wärmeleitend ist.In memory cells with electric insulating housings the channel components are preferably made of metal, in particular Aluminum. The heat exchange channels can then run straight in the channel components, since the metal has good thermal conductivity is.
Die Herstellung der Kanalbauteile kann vereinfacht werden, wenn einzelne Teile der Kanalbausteine für sich gefertigt und danach zu einem kompletten Kanalbauteil zusammengefügt werden. Die Wärmetauscherkanäle können aus mit Nuten versehenen Platten, auf die ebene Platten geklebt werden, hergestellt werden.The production of the channel components can be simplified if individual parts of the channel blocks for themselves manufactured and then joined together to form a complete channel component. The heat exchanger channels can off grooved plates to which flat plates are glued become.

Der Kühler kann entsprechend einem Kraftfahrzeugkühler aufgebaut sein. Ein Lüfter kann am Kühler für die Durchleitung von Luft vorgesehen sein, wobei eine Temperaturmessung des Temperiermittels vorteilhaft ist und der Lüfter nur bei Überschreiten einer vorgebbaren Temperatur des Temperiermittels eingeschaltet wird.The flow distributor head and the Return manifold head are in an advantageous embodiment in a circuit with a pump and a cooler connected. The cooler can be constructed according to a motor vehicle radiator. A fan can on the radiator for the Passage be provided by air, wherein a temperature measurement of the Temperature control is advantageous and the fan only when exceeded a predetermined temperature of the temperature control turned on becomes.
Ein erfindungsgemäßer Energiespeicher läßt sich besonders vorteilhaft bei einem Elektrofahrzeug einsetzen. Das Fahrzeug kann als Energiequelle eine Brennstoffzelle aufweisen, wobei der Energiespeicher die für schnelle Geschwindigkeitsänderungen notwendige Energie schnell verfügbar macht, während die Brennstoffzelle, die ein längeres Ansprechverhalten hat, den Energiespeicher in Perioden konstanter Betriebsverhältnisse auflädt.An inventive energy storage can be use particularly advantageous in an electric vehicle.
