Moderne elektrochemische Hochleistungsenergiespeicher (kurz: Hochleistungsbatterien), wie z. B. Nickelmetallhydrid-Batterien und Lithiumionen-Batterien, die beispielsweise in Elektrofahrzeugen oder in Hybridfahrzeugen verwendet werden, erfordern nicht nur ein ausgefeiltes Batteriemanagement, sondern auch eine effiziente Temperierung der einzelnen elektrochemischen Speicherzellen (kurz: Einzelzellen), um eine möglichst gute Leistung des elektrochemischen Energiespeichers zu gewährleisten und Schäden an ihm zu verhindern.modern Electrochemical high-performance energy storage (short: high-performance batteries), such as Nickel metal hydride batteries and lithium ion batteries, for example, in electric vehicles or in hybrid vehicles not only require sophisticated battery management, but also an efficient temperature control of the individual electrochemical Memory cells (in short: single cells) to one as possible To ensure good performance of the electrochemical energy storage and to prevent damage to it.
Hierfür können in den elektrochemischen Energiespeichern Wärmetauscher vorgesehen sein.Therefor can in the electrochemical energy storage heat exchanger be provided.

Vorteilhafte Weiterbildungen sind Gegenstand der abhängigen Ansprüche.advantageous Further developments are the subject of the dependent claims.
Ein erfindungsgemäßer Wärmetauscher für einen elektrochemischen Energiespeicher umfasst mindestens eine Reihe einander im Wesentlichen parallel verlaufender, von einem Temperiermedium durchströmbarer Wärmetauscherkanäle. Der elektrochemische Energiespeicher umfasst mindestens eine Reihe nebeneinander angeordneter elektrochemischer Speicherrundzellen. Die Wärmetauscherkanäle sind wellenförmig so ausbildbar, dass jeweils eine Mantelfläche einer Speicherrundzelle großflächig auf einer von zwei Seiten der Wärmetauscherkanäle und eine Mantelfläche einer benachbarten Speicherrundzelle derselben Reihe auf der jeweils anderen Seite der Wärmetauscherkanäle anordenbar sind.One inventive heat exchanger for a electrochemical energy storage comprises at least one row each other substantially parallel, can be flowed through by a temperature control medium Heat exchanger channels. The electrochemical energy storage includes at least one row of juxtaposed electrochemical Memory round cells. The heat exchanger channels are undulating so formable that in each case a lateral surface a memory round cell over a large area on a from two sides of the heat exchanger channels and one Lateral surface of an adjacent memory cell of the same Row on the other side of the heat exchanger channels can be arranged.
Erfindungsgemäß sind die Wärmetauscherkanäle aus einem flexiblen Material gebildet.According to the invention the heat exchanger channels made of a flexible material educated.
Bei starr positionierten Speicherrundzellen kann so ein Formschluss zwischen den Speicherrundzellen und den Wärmetauscherkanälen erreicht werden, so dass eine besonders große Fläche der Wärmetauscherkanäle mit den Speicherrundzellen in Kontakt ist und damit ein besserer Wärmeübergang und eine verbesserte Kühlleistung möglich ist. Im Vergleich dazu weisen Wärmetauscherplatten, die als Profile aus einem starren Kunststoff (beispielsweise PETG) vakuumgezogen und zur Bildung der Wärmetauscherkanäle verschweißt sind infolge der Starrheit des Materials und der Fertigungstoleranzen eine wesentlich geringere Kontaktfläche zu den Speicherrundzellen und damit einen ungünstigeren Wärmeübergang auf. Der erfindungsgemäße Wärmetauscher ist weniger spröde und damit robuster als die starren Kunststofflösungen. Somit sind auch eine Steigerung der Lebensdauer und eine geringere Ausfallwahrscheinlichkeit des elektrochemischen Energiespeichers möglich. Durch den vergleichsweise einfachen Aufbau sind geringe Herstellzeit und damit geringe Produktionskosten erzielbar.at rigidly positioned storage round cells can thus form-fit between the storage round cells and the heat exchanger channels be achieved, leaving a particularly large area the heat exchanger channels with the storage round cells is in contact and thus a better heat transfer and an improved cooling capacity is possible. Compared to have heat exchanger plates, which as a profile of a rigid plastic (eg PETG) vacuum drawn and formed the heat exchanger channels are welded due to the rigidity of the material and the manufacturing tolerances much smaller contact surface with the storage round cells and thus a less favorable heat transfer on. The heat exchanger according to the invention is less brittle and thus more robust than the rigid plastic solutions. Thus, an increase in life and a lower Failure probability of the electrochemical energy store possible. Due to the comparatively simple structure low production time and thus low production costs achieved.
Durch die Flexibilität wird, anders als bei spröden Werkstoffen, erreicht, dass mechanische Belastungen wie Rütteln oder Scheuern sich weniger auf den elektrochemischen Energiespeicher auswirken. Dies gilt insbesondere dann, wenn die elektrochemischen Speicherrundzellen liegend angeordnet werden, was bei einem Unterbodenanbau erforderlich sein kann. Eine Zerstörung des Wärmetauschers infolge beschleunigter Massen der elektrochemischen Rundzellen wird durch die Flexibilität der Wärmetauscherkanäle verhindert.By the flexibility becomes, unlike brittle Materials that achieves that mechanical stresses such as shaking or scrub less on the electrochemical energy storage impact. This is especially true when the electrochemical Storage round cells are arranged horizontally, resulting in a subsoil cultivation may be required. Destruction of the heat exchanger due accelerated masses of round electrochemical cells is through the flexibility of the heat exchanger channels prevented.
Bevorzugt sind die Wärmetauscherkanäle als Schläuche ausgebildet, insbesondere aus Silikon. Solche Schläuche sind druckstabil sowohl bezüglich eines hydraulischen Innendrucks als auch bezüglich eines mechanischen Außendrucks, wie er beim Anpressen der Schläuche an die Speicherrundzellen auftreten kann.Prefers are the heat exchanger channels as hoses formed, in particular made of silicone. Such tubes are pressure stable both with respect to a hydraulic internal pressure as well as with respect to an external mechanical pressure, as it occurs when pressing the hoses to the storage round cells can.
Vorzugsweise ist ein Durchmesser der Wärmetauscherkanäle größer gewählt als ein Zwischenraum zwischen den Speicherrundzellen, um eine möglichst große Kontaktfläche zwischen den Speicherrundzellen und den Wärmetauscherkanälen sicherzustellen.Preferably is a diameter of the heat exchanger channels larger chosen as a space between the storage round cells, to the largest possible contact surface between the storage round cells and the heat exchanger channels sure.
In einer bevorzugten Ausführungsform sind zwei Sammler vorgesehen, die in die Enden der Wärmetauscherkanäle münden, so dass deren Temperiermedium im Sammler zusammengeführt ist. Am Sammler können Stutzen zur Befestigung der Wärmetauscherkanäle vorgesehen sein. Diese können zusätzlich mit Sicherungselementen auf den Stutzen gesichert sein.In a preferred embodiment, two collectors are provided, which open into the ends of the heat exchanger channels, so that their temperature control is brought together in the collector. At the collector neck can be provided for mounting the heat exchanger channels. These can additionally with securing elements on the nozzle be assured.
Zur Temperierung mehrerer, einander im Wesentlichen paralleler Reihen von elektrochemischen Speicherrundzellen können mehrere, einander im Wesentlichen parallele Reihen von Wärmetauscherkanälen vorgesehen sein.to Temperature control of several, substantially parallel rows of electrochemical storage round cells, several, mutually substantially parallel rows of heat exchanger channels be provided.
Die elektrochemischen Rundzellen können starr in einem Trägerrahmen positioniert oder miteinander und mit den Wärmetauscherkanälen verspannt sein.The electrochemical round cells can be rigid in a support frame positioned or with each other and with the heat exchanger channels be tense.
Der Wärmetauscher kann zum Temperieren eines elektrochemischen Energiespeichers, beispielsweise einer Hochvoltbatterie, in einem Fahrzeug, insbesondere einem Elektrofahrzeug oder einem Hybridfahrzeug, verwendet werden.Of the Heat exchanger can be used to temper an electrochemical Energy storage, such as a high-voltage battery, in one Vehicle, in particular an electric vehicle or a hybrid vehicle, be used.
Als Temperiermedium kommt eine Flüssigkeit, beispielsweise eine Klimaflüssigkeit eines Fahrzeugklimaanlage, oder Luft in Frage.When Tempering medium comes a liquid, for example an environmental fluid of a vehicle air conditioner, or air in question.
