Description
Die Erfindung betrifft eine Vorrichtung zur Kühlung einer Batterie eines Fahrzeuges gemäß dem Oberbegriff des Anspruchs 1.The The invention relates to a device for cooling a battery a vehicle according to the preamble of the claim 1.
Batterien für Fahrzeuganwendungen, insbesondere für Hybridanwendungen, bestehen aus mehreren in Reihe und/oder parallel geschalteten Einzelzellen, welche sich meist mit einer zugehörigen Elektronik und Vorrichtungen zur Kühlung in einem gemeinsamen Batteriegehäuse befinden. Aus dem Stand der Technik sind verschiedene Verfahren und Vorrichtungen zur Kühlung bekannt. Dabei kann es sich beispielsweise um eine indirekte Kühlung mittels Einbindung der Batterie in einen Kältemittelkreislauf einer Fahrzeugklimaanlage oder eine direkte Kühlung der Einzelzellen mittels vorgekühlter Luft, die zwischen die Zellen geleitet wird, handeln.batteries for vehicle applications, especially for hybrid applications, consist of several series and / or parallel single cells, which are usually associated with electronics and Devices for cooling in a common battery case are located. From the prior art are various methods and devices for cooling known. It can be for example, an indirect cooling by means of integration the battery in a refrigerant circuit of a vehicle air conditioning or a direct cooling of the individual cells by means of pre-cooled Air passed between the cells act.
Die Kühlung mittels des Kältemittelskreislaufes der Fahrzeugklimaanlage wird aus Bauraumgründen vorzugsweise angewendet. Dabei ist am Zellverbund der Einzelzellen eine von einem Wärmeleitmedium, im Weiteren als Kühlmittel bezeichnet, durchströmte Wärmeleitplatte angeordnet. Eine derartig gekühlte Batterie mit einer Wärmeleitplatte zum Temperieren der Batterie ist aus der 102007010739.2-45 (P809883/DE/1) bekannt. Die Batterie weist mehrere parallel und/oder seriell miteinander verschaltete Einzelzellen auf, die Wärme leitend mit der Wärmeleitplatte verbunden sind. In der Wärmeleitplatte ist eine für das Kühlmittel durchströmbare Kanalstruktur angeordnet, wobei die Wärmeleitplatte über herausführende Anschlussquerschnitte für die Kanalstruktur verfügt. Die Wärmeleitplatte weist im Bereich der Pole der Einzelzellen Bohrungen auf, wobei die Pole der Einzelzellen durch die Bohrungen hindurch ragen. Zur thermischen Kopplung der Batterie mit dem Kältemittelkreislauf der Fahrzeugklimaanlage kann beispielsweise ein Wärmetauscher vorgesehen sein.The Cooling by means of the refrigerant circuit of the Vehicle air conditioning is preferred for space reasons applied. Here is at the cell composite of the single cells one of a Wärmeleitmedium, hereinafter referred to as coolant, flowed through Wärmeleitplatte arranged. A such cooled battery with a heat conducting plate for temperature control of the battery is from the 102007010739.2-45 (P809883 / DE / 1) known. The battery has several parallel and / or serial with each other interconnected single cells, the heat conducting with the Heat conducting plate are connected. In the heat conducting plate is a coolant that can be flowed through Channel structure arranged, wherein the heat conduction plate over leading connecting cross sections for the channel structure has. The heat conducting plate has in the region of the poles of the individual cells Drill holes, with the poles of the single cells through the holes protrude through. For the thermal coupling of the battery with the refrigerant circuit the vehicle air conditioner may, for example, a heat exchanger be provided.
Während einer Fahrt des Fahrzeuges bei geringen Umgebungstemperaturen ist ein durch den Fahrtwind erzeugter Luftmassenstrom über den Wärmetauscher ausreichend, um die von der Batterie erzeugte Verlustwärme abzuführen. Bei geringen Geschwindigkeiten des Fahrzeuges, beispielsweise in Stillstandsphasen des Fahrzeuges, oder bei höheren Außentemperaturen ist der Luftmassenstrom über den Wärmetauscher nicht mehr ausreichend, so dass mittels der thermischen Kopplung mit dem Kältemittelkreislauf der Klimaanlage eine verbesserte Wärmeabfuhr erzielbar ist.While a ride of the vehicle at low ambient temperatures is a generated by the wind air mass flow over the heat exchanger sufficient to that of the battery dissipate generated heat loss. At low Speeds of the vehicle, for example in standstill phases of the vehicle, or at higher outside temperatures is the air mass flow through the heat exchanger no longer sufficient, so that by means of thermal coupling with the refrigerant circuit of the air conditioner improved heat dissipation is achievable.
Aus
der
Der Erfindung liegt die Aufgabe zugrunde, eine gegenüber dem Stand der Technik verbesserte Vorrichtung zur Kühlung einer Batterie eines Fahrzeuges anzugeben, mittels welcher eine effiziente Kühlung der Batterie bei verschieden Umgebungstemperaturen realisierbar ist.Of the Invention is based on the object, a relation to the Prior art improved device for cooling a Specify battery of a vehicle, by means of which an efficient cooling the battery can be realized at different ambient temperatures is.
Die Aufgabe wird erfindungsgemäß mit einer Vorrichtung zur Kühlung einer Batterie eines Fahrzeuges, die von einem Kühlmittel durchströmbar ist, gelöst, wobei eine Kühlmittelpumpe das Kühlmittel innerhalb eines Kühlmittelkreislaufes fördert und der Kühlmittelkreislauf über einen Wärmetauscher mit einem Kältemittelkreislauf einer Kältemaschine thermisch gekoppelt ist. Erfindungsgemäß ist die Kältemaschine eine Absorptionskältemaschine.The Object is according to the invention with a device for cooling a battery of a vehicle by a Coolant can flow through, dissolved, wherein a coolant pump, the coolant within a coolant circuit promotes and the coolant circuit over a heat exchanger with a refrigerant circuit a refrigerator is thermally coupled. According to the invention the chiller an absorption chiller.
Eine derartige Absorptionskältemaschine weist gegenüber den im Stand der Technik genutzten Kompressionskältemaschinen vor allem den Vorteil auf, dass eine Kühlung der Batterie auch bei niedrigen Temperaturen, insbesondere bei Temperaturen unter 0°C, sichergestellt ist. Bei Kompressionskältemaschinen kann bei geringen Temperaturen eine zu starke Kühlung des Kältemittels in einem Kondensator des Kältemittelkreislaufes stattfinden, so dass eine notwendige Unterkühlung des Kältemittels nach dem Kondensator nicht ausführbar ist und somit die Möglichkeit besteht, dass der thermodynamische Kühlprozess nicht zustande kommt. Aufgrund einer relativ geringen notwendigen Kühlleistung besteht weiterhin der Vorteil, dass der Kältemittelkreislauf kleinbauend und somit Platz sparend ausführbar ist.A Such absorption chiller faces the compression refrigerators used in the prior art especially the advantage of having a cooling of the battery even at low temperatures, especially at temperatures below 0 ° C, is ensured. For compression refrigerators At low temperatures too much cooling of the Refrigerant in a condenser of the refrigerant circuit take place, so that a necessary subcooling of the refrigerant after the capacitor is not executable and thus the possibility that the thermodynamic cooling process does not materialize comes. Due to a relatively low necessary cooling capacity There is also the advantage that the refrigerant circuit kleinbauend and thus space-saving executable.
Mittels der Absorptionskältemaschine ist ein Kältemittel im Kältemittelkreislauf anhand einer Temperaturbeeinflussung einer Kältemittellösung verdichtbar, so dass ein zusätzlicher Verdichter entfallen kann, was zu einer Geräuschverringerung gegenüber den Kompressionskältemaschinen führt.through The absorption chiller is a refrigerant in the refrigerant circuit based on a temperature influence a refrigerant solution compressible, so that a additional compressor can be omitted, resulting in a reduction in noise leads to the compression refrigerators.
Zur Zirkulation des Kältemittels in dem Kältemittelkreislauf ist eine Kältemittelpumpe vorgesehen, mittels welcher einer Trenneinheit eine Kältemittellösung zuführbar ist, wobei anhand der Trenneinheit unter Wärmezufuhr das Kältemittel von einem Lösungsmittel trennbar und verdampfbar ist. Bei dem Kältemittel handelt es sich vorzugsweise um Ammoniak oder Lithiumbromid, wobei das Lösungsmittel insbesondere Wasser ist. Wasser weist als Lösungsmittel insbesondere den Vorteil auf, dass es nicht giftig bzw. umweltschädlich ist.to Circulation of the refrigerant in the refrigerant circuit a refrigerant pump is provided, by means of which a Separation unit fed to a refrigerant solution is, by means of the separation unit under heat supply the Refrigerant separable from a solvent and is vaporizable. The refrigerant is preferably to ammonia or lithium bromide, wherein the solvent in particular Water is. Water has as a solvent in particular the advantage that it is not toxic or harmful to the environment is.
Zu dieser Trennung ist die Trenneinheit direkt oder über einen weiteren Kühlmittelkreislauf mit einem Heizelement verbunden. Bei dem Heizelement handelt es sich gemäß einer Weiterbildung der Erfindung um einen Brenner oder ein elektrisches Heizelement, mittels welchem die Trenneinheit direkt oder das in dem weiteren Kühlmittelkreislauf befindliche Kühlmittel erwärmbar sind. Eine direkte Erwärmung der Kältemittellösung, beispielsweise anhand eines Brenners, führt in gewinnbringender Weise zu einem besonders effektiven Betrieb der Absorptionskältemaschine.For this separation, the separation unit is connected directly or via a further coolant circuit with a heating element. The heating element is according to a development of Invention to a burner or an electric heating element, by means of which the separation unit directly or the coolant located in the further coolant circuit can be heated. Direct heating of the refrigerant solution, for example by means of a burner, leads in a profitable manner to a particularly effective operation of the absorption chiller.
In einer vorteilhaften Ausgestaltung der Erfindung ist der weitere Kühlmittelkreislauf zur Kühlung einer Verbrennungskraftmaschine des Fahrzeuges vorgesehen. Somit ist eine Verlustwärme der Verbrennungskraftmaschine zur Erwärmung der Kühlmittellösung verwendbar, was zu einem geringen Energiebedarf beim Betrieb der Absorptionskältemaschine führt.In an advantageous embodiment of the invention is the further Coolant circuit for cooling an internal combustion engine provided the vehicle. Thus, a loss of heat the internal combustion engine for heating the coolant solution usable, resulting in low energy consumption during operation of the Absorption chiller leads.
Nach der Trennung des Kältemittels von dem Lösungsmittel ist das Kältemittel einem in Strömungsrichtung des Kältemittels nach der Trenneinheit angeordneten Kondensator zuführbar, anhand dessen das dampfförmige Kältemittel unter Wärmeabgabe in einen flüssigen Aggregatzustand überführbar ist. Zur Zuführung des Kältemittels ist eine erste Versorgungsleitung vorgesehen.To the separation of the refrigerant from the solvent the refrigerant is one in the flow direction the refrigerant arranged after the separation unit condenser be supplied, based on which the vapor refrigerant transferred under heat in a liquid state of matter is. For supplying the refrigerant is a first supply line intended.
Der Kältemittelkreislauf umfasst weiterhin einen in Strömungsrichtung des Kältemittels nach dem Kondensator angeordneten Verdampfer, anhand dessen das in dem Kondensator verflüssigte Kältemittel verdampfbar ist. Dabei nimmt das Kältemittel Wärme auf. Aus diesem Grund ist zur Kühlung der Batterie der Verdampfer mit dem Wärmetauscher des Kühlmittelkreislaufes thermisch gekoppelt. Somit entzieht das verdampfende Kältemittel dem in dem Kühlmittelkreislauf der Batterie zirkulierenden Kühlmittel Wärme, so dass die Batterie kühlbar bzw. deren Verlustwärme abführbar ist. Zum Ausgleich einer Volumenänderung des Kühlmittels aufgrund der Temperaturveränderungen ist in dem Kühlmittelkreislauf ein Ausgleichsbehälter angeordnet.Of the Refrigerant circuit further comprises one in the flow direction of the refrigerant after the condenser arranged evaporator, based on which the liquefied in the condenser refrigerant is vaporizable. The refrigerant absorbs heat on. For this reason, to cool the battery is the Evaporator with the heat exchanger of the coolant circuit thermally coupled. Thus, evaporates the evaporating refrigerant the circulating in the coolant circuit of the battery Coolant heat, making the battery coolable or whose heat loss is dissipated. To compensate a volume change of the coolant due the temperature changes is in the coolant circuit arranged a surge tank.
Um das Kältemittel wieder in dem Lösungsmittel zu lösen, sind diese einem nach dem Verdampfer vor der Kältemittelpumpe angeordneten Absorber zuführbar. Das Lösungsmittel ist dem Absorber dabei in einer bevorzugten Weiterbildung der Erfindung anhand einer zweiten Versorgungsleitung, welche den Absorber und die Trenneinheit verbindet, zuführbar.Around return the refrigerant to the solvent These are one after the evaporator before the refrigerant pump arranged absorber fed. The solvent is the absorber in a preferred embodiment of the invention by means of a second supply line, which the absorber and the separation unit connects, can be fed.
