Die Erfindung betrifft eine Speichereinheit zum Speichern elektrischer Energie. Die Speichereinheit weist wenigstens einen Energiespeicher auf, welcher wenigstens einen positiven und wenigstens einen negativen elektrischen Anschluss aufweist. Der Energiespeicher ist ausgebildet, über den positiven Anschluss und den negativen Anschluss mit elektrischer Energie aufgeladen und entladen zu werden.The invention relates to a storage unit for storing electrical energy. The memory unit has at least one energy store, which has at least one positive and at least one negative electrical connection. The energy storage device is designed to be charged and discharged via the positive connection and the negative connection with electrical energy.
Bei aus dem Stand der Technik bekannten Energiespeichern als Bestandteil einer Speichereinheit sind die Energiespeicher in einem Gehäuse angeordnet, beispielsweise in ein Mold-Gehäuse eingebettet. Bei Energiespeichern in Form von Wickelkondensatoren besteht das Problem, dass eine in dem Energiespeicher entstehende Verlustwärme zu einer Erwärmung des Energiespeichers und damit zu einer thermischen Ausdehnung des Energiespeichers führt.In known from the prior art energy storage as part of a storage unit, the energy storage are arranged in a housing, for example, embedded in a mold housing. In the case of energy stores in the form of wound capacitors, there is the problem that a heat loss arising in the energy store leads to a heating of the energy store and thus to a thermal expansion of the energy store.
Offenbarung der ErfindungDisclosure of the invention
Erfindungsgemäß ist der positive und/oder der negative Anschluss mindestens mittelbar mit einem Kühlelement wirkverbunden. So kann über den elektrischen Anschluss Wärme an das Kühlelement abgeführt werden. Das Kühlelement bildet in dieser Ausführungsform eine Wärmesenke. Das Kühlelement kann beispielsweise durch ein massives Aluminiumstück gebildet sein.According to the invention, the positive and / or the negative connection is at least indirectly operatively connected to a cooling element. Thus, heat can be dissipated to the cooling element via the electrical connection. The cooling element forms a heat sink in this embodiment. The cooling element may be formed for example by a solid aluminum piece.
Die Speichereinheit ist beispielsweise Bestandteil eines Fahrzeugs insbesondere eines elektrisch angetriebenen Kraftfahrzeugs, beispielsweise ein Zwischenkreiskondensator eines elektrischen Antriebs. Das Kühlelement kann in dieser Ausführungsform vorteilhaft mit einem Teil des Kraftfahrzeugs, beispielsweise einem Teil einer Karosserie oder einem anderen Teil des Kraftfahrzeugs verbunden sein, welches ausgebildet ist, Wärme insbesondere mittels Konvektion an eine Umgebung abzugeben. Das Kühlelement kann in einer anderen Ausführungsform mit einem Kühlkörper verbunden sein. Der Kühlkörper weist beispielsweise Rippen auf, durch welche Umgebungsluft der Umgebung strömen kann und so die Wärme mittels Konvektion abführen kann.The storage unit is for example part of a vehicle, in particular of an electrically driven motor vehicle, for example a DC link capacitor of an electric drive. In this embodiment, the cooling element can advantageously be connected to a part of the motor vehicle, for example a part of a body or another part of the motor vehicle, which is designed to release heat, in particular by means of convection, to an environment. The cooling element may be connected in another embodiment with a heat sink. The heat sink has ribs, for example, through which ambient air can flow around the environment and thus dissipate the heat by means of convection.
In einer bevorzugten Ausführungsform weist die Speichereinheit eine mit dem positiven Anschluss verbundene Kontaktschiene und eine mit dem negativen Anschluss verbundene Kontaktschiene auf, wobei die Kontaktschienen wenigstens mit einem Abschnitt aus einem den wenigstens einen Energiespeicher und teilweise die Kontaktschienen aufnehmenden Gehäuse der Speichereinheit herausragen. Die Kontaktschienen sind wenigstens auf dem Abschnitt mit einem Kühlelement thermisch leitend verbunden, sodass über die elektrischen Anschlüsse der Energiespeicher und über die Kontaktschienen Wärme aus dem Energiespeicher abgeführt werden kann. Der Energiespeicher kann so vorteilhaft nicht überhitzen.In a preferred embodiment, the memory unit has a contact rail connected to the positive terminal and a contact rail connected to the negative terminal, wherein the contact rails protrude at least with a portion of a housing of the storage unit accommodating the at least one energy store and partially the contact rails. The contact rails are thermally conductively connected at least on the section with a cooling element, so that heat can be removed from the energy store via the electrical connections of the energy store and via the contact rails. The energy store can not overheat so advantageous.
Die Kontaktschienen sind beispielsweise ausgebildet, die positiven und negativen Anschlüsse der Energiespeicher mit einem äußeren elektrischen Anschluss der Speichereinheit zu verbinden. Das Gehäuse der Speichereinheit, welches wie vorab beschrieben den Energiespeicher und wenigstens teilweise die Kontaktschienen aufnimmt, ist beispielsweise ein Kunststoffgehäuse, insbesondere ein gespritztes Kunststoffgehäuse, in welches die Energiespeicher und wenigstens ein Teil der Kontaktschienen eingebettet sind.The contact rails are formed, for example, to connect the positive and negative terminals of the energy storage with an external electrical connection of the storage unit. The housing of the storage unit, which as described above, the energy storage and at least partially receives the contact rails, for example, a plastic housing, in particular a molded plastic housing, in which the energy storage and at least a portion of the contact rails are embedded.
In einer bevorzugten Ausführungsform ist ein Wärmeübergangswiderstand von dem Energiespeicher zu einer Umgebung über das Gehäuse größer als ein Wärmeübergangswiderstand von dem Energiespeicher über die Anschlüsse hin bis zu dem Kühlelement. So kann vorteilhaft über die elektrischen Anschlüsse des Energiespeichers, insbesondere dem positiven und dem negativen Anschluss des Energiespeichers, Verlustwärme, die in dem Energiespeicher entsteht, über die Anschlüsse, weiter bevorzugt über die Kontaktschiene bis hin zu dem Kühlelement fließen. So ist ein über die Anschlüsse des Energiespeichers fließender Wärmestrom größer als ein Wärmestrom aus dem Inneren des Energiespeichers über eine Oberfläche des Energiespeichers und weiter über das Gehäuse an eine das Gehäuse umschließende Umgebung.In a preferred embodiment, a heat transfer resistance from the energy store to an environment via the housing is greater than a heat transfer resistance from the energy store via the connections to the cooling element. Thus, via the electrical connections of the energy store, in particular the positive and the negative connection of the energy store, heat loss, which arises in the energy store, can advantageously flow via the connections, more preferably via the contact rail, as far as the cooling element. Thus, a heat flow flowing via the connections of the energy store is greater than a heat flow from the interior of the energy store via a surface of the energy store and further via the housing to an environment enclosing the housing.
In einer bevorzugten Ausführungsform ist die Kontaktschiene wenigstens auf einem Flächenabschnitt mit einem als Kühldom ausgebildeten Kühlelement thermisch verbunden. So können vorteilhaft Flächenbereiche der Kontaktschiene zum Abführen von Wärme genutzt werden, welche bevorzugt eben ausgebildet sind oder welche nicht mittels beispielsweise eines elektrischen Anschlusses zum Anschließen der Speichereinheit kontaktiert werden, wo eine räumliche Umgebung der Kontaktschiene von dem elektrischen Anschluss beziehungsweise von mit dem elektrischen Anschluss verbundenen weiteren Komponenten belegt ist.In a preferred embodiment, the contact rail is thermally connected at least on a surface portion with a cooling element designed as a cooling dome. Thus, surface areas of the contact rail can advantageously be used for dissipating heat, which are preferably planar or which are not contacted by, for example, an electrical connection for connecting the storage unit, where a spatial environment of the contact rail of the electrical connection or connected to the electrical connection other components is occupied.
In einer bevorzugten Ausführungsform weist die Kontaktschiene zwei einander gegenüberliegende Flächen auf, wobei die Kontaktschiene wenigstens auf einer Fläche vollflächig thermisch durch ein Kühlelement kontaktiert ist. So kann vorteilhaft auf einer Fläche der Kontaktschiene, welche beispielsweise einer Fläche der Kontaktschiene gegenüberliegt, die beispielsweise sich senkrecht von der Fläche wegerstreckende elektrische Anschlüsse aufweist, mittels des Kühlelements auf einer Fläche vollflächig kontaktiert werden, welche wenigstens räumlich nicht mit weiteren Komponenten verbunden ist. So kann ein Flächenbereich der Kontaktschiene, welcher räumlich freiliegt, von dem Kühlelement kontaktiert werden, welches den freiliegenden Raum einnehmen kann.In a preferred embodiment, the contact rail on two opposing surfaces, wherein the contact rail is contacted at least on a surface over its entire surface thermally by a cooling element. Thus, advantageously, on a surface of the contact rail, which faces, for example, a surface of the contact rail, the electrical connections extending, for example, vertically away from the surface has, by means of the cooling element on a surface are contacted over the entire surface, which is at least spatially not connected to other components. Thus, a surface region of the contact rail, which is spatially exposed, can be contacted by the cooling element, which can occupy the exposed space.
In einer bevorzugten Ausführungsform ist die Kontaktschiene wenigstens auf einem Flächenabschnitt mit einer flachen Erstreckung zwischen zwei Kühlelementen angeordnet, wobei die Kühlelemente die Kontaktschiene auf dem Flächenabschnitt zwischeneinander einschließen. So kann die Kontaktschiene vorteilhaft – nach Art eines Sandwiches – zwischen zwei Kühlelementen eingepresst sein und Wärme optimal über zwei einander gegenüberliegende Oberflächen des Flächenabschnitts an die Kühlelemente abführen.In a preferred embodiment, the contact rail is arranged at least on a surface section with a flat extension between two cooling elements, wherein the cooling elements enclose the contact rail on the surface section between one another. Thus, the contact rail can advantageously - be pressed in the manner of a sandwich - between two cooling elements and dissipate heat optimally over two opposing surfaces of the surface portion of the cooling elements.
Die Erfindung betrifft auch ein Verfahren zum Abführen von Wärme aus einem elektrischen Energiespeicher einer Speichereinheit. Bei dem Verfahren wird über einen positiven und einen negativen elektrischen Anschluss des Energiespeichers Wärme, insbesondere Verlustwärme aus dem Inneren des Energiespeichers an eine Wärmesenke außerhalb der Speichereinheit abgeführt.The invention also relates to a method for removing heat from an electrical energy store of a storage unit. In the method, heat is dissipated via a positive and a negative electrical connection of the energy store, in particular heat loss from the interior of the energy store to a heat sink outside the storage unit.
Bevorzugt wird bei dem Verfahren die Wärme von dem Anschluss über eine Kontaktschiene an die Wärmesenke abgeführt. Die Kontaktschiene ist ausgebildet, den positiven oder negativen Anschluss des Energiespeichers mit einem äußeren elektrischen Anschluss der Speichereinheit zu verbinden.Preferably, in the method, the heat is dissipated from the terminal via a contact rail to the heat sink. The contact rail is designed to connect the positive or negative terminal of the energy store to an external electrical terminal of the storage unit.
Bevorzugt wird die Kontaktschiene von einem Kühlelement als Wärmesenke kontaktiert. Das Kühlelement kann selbst als ein Kühlkörper mit Rippen ausgebildet sein.Preferably, the contact rail is contacted by a cooling element as a heat sink. The cooling element may itself be formed as a heat sink with ribs.
In einer anderen Ausführungsform ist das Kühlelement, welches beispielsweise blockförmig ausgebildet ist, mit einem Kühlkörper thermisch verbunden, wobei der Kühlkörper Rippen aufweist, welche ausgebildet sind, mittels Konvektion Wärme an eine Umgebungsluft abzugeben.In another embodiment, the cooling element, which is formed block-shaped, for example, thermally connected to a heat sink, wherein the heat sink has ribs, which are designed to deliver by convection heat to an ambient air.
In einer bevorzugten Ausführungsform des Verfahrens ist die Kontaktschiene wenigstens auf einem Flächenabschnitt mit einer flachen Erstreckung zwischen zwei Kühlelementen eingeschlossen, wobei die Wärme von der Kontaktschiene an die Kühlelemente abgeführt wird.In a preferred embodiment of the method, the contact rail is enclosed at least on a surface section with a flat extension between two cooling elements, the heat being dissipated from the contact rail to the cooling elements.
