Nachteilig an einer solchen Ausführungsform zur Nutzung der Abwärme eines Verbrennungsmotors ist, dass neben einer ebenfalls möglichen Nutzung der Abgaswärme nur noch die Abwärme der Abgasrückführungseinrichtung genutzt wird, obwohl noch weitere Abwärmequellen vorhanden sind, deren Abwärme ebenfalls einer Nutzung zugeführt werden könnte. Die Schwierigkeit in der Nutzung dieser weiteren Abwärmequellen liegt allerdings in der im Vergleich zum Abgas geringeren Temperatur dieser weiteren Abwärmequellen.adversely on such an embodiment for the use of waste heat an internal combustion engine is that in addition to one also possible Using the exhaust heat only the waste heat of the exhaust gas recirculation device is used, although still more waste heat sources available are, the waste heat also fed to a use could be. The difficulty in using this further Waste heat sources is however in the comparison to the Exhaust gas lower temperature of these other waste heat sources.
Die vorliegende Erfindung beschäftigt sich mit dem Problem, für eine solche Abwärmenutzungsvorrichtung zur Nutzung der Abwärme der Abgase der Abgasrückführungseinrichtung eine verbesserte oder zumindest eine andere Ausführungsform anzugeben, die sich insbesondere dadurch auszeichnet, dass die Schwierigkeiten in der Nutzung weiterer Abwärmequellen mit vergleichsweise niedrigerer Temperatur gelöst werden.The present invention addresses the problem of such a waste heat utilization device for utilizing the waste heat of the exhaust gases the exhaust gas recirculation device to provide an improved or at least another embodiment, which is particularly characterized in that the difficulties in the use of other waste heat sources are solved with relatively lower temperature.
Erfindungsgemäß wird diese Aufgabe durch den Gegenstand des unabhängigen Anspruchs gelöst. Vorteilhafte Ausführungsformen sind Gegenstand der abhängigen Ansprüche.According to the invention This object is achieved by the subject matter of the independent claim solved. Advantageous embodiments are the subject the dependent claims.
Die Erfindung beruht auf dem allgemeinen Gedanken, den Kühlflüssigkeitskreislauf der über einen Abgaswärmetauscher das Abgas der Abgasrückführungseinrichtung kühlt und dessen Kühlflüssigkeit über einen Kühlflüssigkeitswärmetauschers mittels eines Arbeitsfluidkreislaufes gekühlt wird, mit einem Motorkühlungskreislauf fluidisch zu verbinden. Diese fluidische Kopplung des Kühlflüssigkeitskreislaufs mit dem Motorkühlungskreislauf hat den Vorteil, dass die in dem Kühlflüssigkeitskreislauf und dem Motorkühlungskreislauf zirkulierende Kühlflüssigkeit zuerst durch den Motor vorerhitzt wird und danach im Abgaswärmetauscher auf eine Temperatur gebracht wird, die den Wirkungsgrad der an den Kühlflüssigkeitswärmetauscher angeschlossenen Wärmekraftmaschine verbessert. Nach dem Durchlaufen des Kühlflüssigkeitswärmetauschers wird die Kühlflüssigkeit in einer Kühleinrichtung, insbesondere in einem Fahrzeugkühler, soweit abgekühlt, dass die Kühlung des Verbrennungsmotors sichergestellt ist. Durch die Einbindung des Motorkühlungskreislaufes in den Kühlflüssigkeitskreislauf der Abgasrückführungseinrichtung kann somit die Motorkühlung, bzw. die in den Motorkühlungskreislauf eingespeiste Wärme als weitere Abwärmequelle durch eine gemeinsame Abwärmenutzungsvorrichtung genutzt werden. Diese Konstruktionsweise erspart zum einen eine separate Abwärmenutzungsvorrichtung zur Nutzung der Abwärme der Motorkühlung und zum anderen kann durch den Kühlflüssigkeitskreislauf der Abgasrückführungseinrichtung gleichzeitig auch die Motorkühlung vorgenommen werden. Somit wird ein Teil der Abwärme zweier Abwärmequellen durch nur eine Wärmekraftmaschine in mechanisch nutzbare Arbeit gewandelt.The The invention is based on the general idea of the coolant circuit the exhaust gas via an exhaust gas heat exchanger Exhaust gas recirculation device cools and the cooling liquid via a coolant heat exchanger by means of a working fluid circuit is cooled with an engine cooling circuit fluidly connect. This fluidic coupling of the coolant circuit with the engine cooling circuit has the advantage that the in the coolant circuit and the engine cooling circuit circulating coolant first through the Engine is preheated and then in the exhaust gas heat exchanger is brought to a temperature which increases the efficiency of the Coolant heat exchanger connected Heat engine improved. After passing through the coolant fluid heat exchanger is the cooling liquid in a cooling device, especially in a vehicle radiator, as far as cooled, that the cooling of the internal combustion engine ensured is. Through the integration of the engine cooling circuit in the coolant circuit of the exhaust gas recirculation device Thus, the engine cooling, or in the engine cooling circuit fed-in heat as a further waste heat source a common waste heat utilization device can be used. This design saves on the one hand a separate waste heat recovery device to use the waste heat of the engine cooling and the others can through the coolant circuit the exhaust gas recirculation device simultaneously also the engine cooling be made. Thus, a Part of the waste heat of two waste heat sources by only a heat engine converted into mechanically usable work.
Eine Kühlflüssigkeit des Kühlflüssigkeitskreislaufs sowie auch ein Arbeitsfluid des Arbeitsfluidskreislaufs kann aus einer lipophilen Flüssigkeit, wie zum Beispiel Öl, einem Ölgemisch oder dergleichen, oder aus einer hydrophilen Flüssigkeit, wie zum Beispiel Wasser, Alkohole, Polyole oder dergleichen aufgebaut sein. Bevorzugt wird im Bereich des Kühlflüssigkeitskreislaufes aufgrund der Kopplung mit der Motorkühlung eine hydrophile Flüssigkeit eingesetzt. Es ist aber auch der Einsatz von lipophilen Flüssigkeiten denkbar.A Coolant of the coolant circuit as well as a working fluid of the working fluid circuit may be off a lipophilic liquid, such as oil, an oil mixture or the like, or a hydrophilic one Liquid, such as water, alcohols, polyols or the like. Preference is given in the area of the coolant circuit due to the coupling with the engine cooling a hydrophilic Liquid used. But it is also the use of lipophilic liquids conceivable.
Wird in einer bevorzugten Ausführungsform eine hydrophile Kühlflüssigkeit oder ein hydrophiles Kühlflüssigkeitsgemisch im Kühlflüssigkeitskreislauf verwendet, so ist die Erhöhung eines Druckes in dem Kühlflüssigkeitskreislauf von Vorteil, da aufgrund des erhöhten Drucks ein Sieden der Kühlflüssigkeit in dem Abgaswärmetauscher verhindert, bzw. zu höheren Temperaturen hin verschoben werden kann. Da die Kühlflüssigkeit in diesem Fall im Abgaswärmetauscher auf eine Temperatur oberhalb der bei Umgebungsdruck vorliegenden Siedetemperatur der Kühlflüssigkeit erhitzbar ist, lässt sich somit mehr Wärme je Kühlflüssigkeitsmenge transportieren.Becomes in a preferred embodiment, a hydrophilic cooling fluid or a hydrophilic coolant mixture in Coolant cycle used, so is the Increasing a pressure in the coolant circuit advantageous because boiling due to the increased pressure the cooling liquid in the exhaust gas heat exchanger prevented, or shifted to higher temperatures can be. Because the cooling liquid in this Fall in the exhaust gas heat exchanger to a temperature above the boiling temperature of the coolant at ambient pressure is heatable, thus can be more heat ever Transport coolant volume.
In einer Weiterentwicklung der bevorzugten Ausführungsform mit einem erhöhten Druck in dem Kühlflüssigkeitskreislauf wird der Kühlflüssigkeitskreislauf durch zumindest eine Pumpe und durch zumindest eine Drosseleinrichtung in zumindest zwei Druckabschnitte unterschiedlichen Drucks unterteilt. Dabei wird zweckmäßigerweise die Pumpe vor dem Abgaswärmetauscher platziert und die Kühlflüssigkeit vor dem Abgaswärmetauscher auf einen erhöhten Druck gebracht. Zweckmäßigerweise nach dem Abgaswärmetauscher ist es möglich, eine Drosseleinrichtung zu installieren, die einen Druckabfall bewerkstelligt. Durch diese Anordnung ist eine Druckerhöhung genau dort im Kühlflüssigkeitskreislauf angeordnet, wo durch sie ein erhöhter Wärmeabtransport ermöglicht wird. Da nach dem Kühlflüssigkeitswärmetauscher die Temperatur der Kühlflüssigkeit abgesenkt worden ist, besteht hier nun keine Notwendigkeit mehr, den erhöhten Druck beizubehalten und es ist möglich, eine Drosseleinrichtung z. B. nach dem Kühlflüssigkeitswärmetauscher zu platzieren. Die nachfolgende Kühleinrichtung muss aufgrund des durch die Drosseleinrichtung bewerkstelligten Druckabfalls nicht druckstabil ausgelegt werden. Somit kann durch den Einsatz von zumindest einer Pumpe und zumindest einer Drosseleinrichtung der Kühlkreislauf in Druckabschnitte unterschiedlichen Drucks unterteilt werden, je nachdem in welchem Abschnitt des Kühlflüssigkeitskreislaufes welcher Druck am sinnvollsten erscheint.In a further development of the preferred embodiment with an increased pressure in the coolant circuit is the cooling fluid circuit by at least a pump and at least one throttle device in at least divided two pressure sections of different pressure. there is expediently the pump in front of the exhaust gas heat exchanger placed and the cooling liquid in front of the exhaust gas heat exchanger brought to an elevated pressure. Conveniently, After the exhaust gas heat exchanger, it is possible a Throttle device to install, which causes a pressure drop. By this arrangement, a pressure increase is right there arranged in the coolant circuit, where through it allows increased heat dissipation becomes. Because after the cooling liquid heat exchanger the temperature of the cooling liquid has been lowered is, there is no need now, the increased Pressure is maintained and it is possible to use a throttle device z. B. after the cooling liquid heat exchanger to place. The following cooling device must due the effected by the throttle device pressure drop not be designed pressure stable. Thus, through the use of at least a pump and at least one throttle device of the cooling circuit divided into pressure sections of different pressure, depending after in which section of the coolant circuit which pressure makes the most sense.
In einer weiteren Ausführungsform ist nach dem Motor und vor der Kühleinrichtung im Kühlflüssigkeitskreislauf eine Bypassleitung angeordnet. Durch diese Bypassleitung ist es möglich, die Menge an Kühlflüssigkeit, die durch den Abgaswärmetauscher geleitet wird, zu regulieren. Dies macht Sinn, falls das Abgas am Anfang des Fahrprozesses, z. B. nach einem Kaltstart, noch nicht die maximale Temperatur erreicht hat, oder falls zum Beispiel der für den Motor benötigte Volumenstrom an Kühlflüssigkeit größer ist, als der optimierte Volumenstrom der Kühlflüssigkeit durch den Abgaswärmetauscher. Durch eine solche Bypassleitung ist es möglich, die Kühlflüssigkeit auf einer optimalen Arbeitstemperatur zu betreiben, damit der Wirkungsgrad des Kühlflüssigkeitswärmetauschers und der daran angeschlossenen Wärmekraftmaschine optimiert ist.In a further embodiment, a bypass line is arranged after the engine and before the cooling device in the cooling liquid circuit. By this bypass line, it is possible to regulate the amount of cooling liquid that is passed through the exhaust gas heat exchanger. This makes sense if the exhaust gas at the beginning of the driving process, for. B. after a cold start, has not yet reached the maximum temperature, or if, for example, the volume flow of cooling liquid required for the engine is greater than the optimized volume flow of the cooling liquid through the exhaust gas heat exchanger. By such a bypass line, it is possible to operate the cooling liquid at an optimum operating temperature, so that the efficiency of the Kühlflüs sigkeitswärmetauschers and the connected heat engine is optimized.
