Die Erfindung beschäftigt sich mit dem Problem, für einen gattungsgemäßen Verbrennungsmotor, eine verbesserte oder zumindest eine alternative Ausführungsform anzugeben, welche sich insbesondere durch einen erhöhten Wirkungsgrad auszeichnet.The Invention deals with the problem for a generic internal combustion engine, a improved or at least one alternative embodiment indicate, which in particular by an increased Efficiency distinguishes.
Dieses Problem wird erfindungsgemäß durch den Gegenstand des unabhängigen Anspruchs 1 gelöst. Vorteilhafte Ausführungsformen sind Gegenstand der abhängigen Ansprüche.This Problem is inventively by the subject of the independent claim 1 solved. advantageous Embodiments are the subject of the dependent Claims.
Die Erfindung beruht auf dem allgemeinen Gedanken, bei einem herkömmlichen Verbrennungsmotor mit einem Kühler zur Kühlung des Verbrennungsmotors an diesem wenigstens einen thermoelektrischen Wandler vorzusehen, welcher das im Kühler zirkulierende Kühlmittel kühlt, aufheizt oder daraus elektrische Energie gewinnt. Hierdurch soll die bisher nutzlos verpuffte und vom Verbrennungsmotor abgegebene Wärme genutzt werden, um daraus elektrische Energie zu gewinnen und dadurch den Wirkungsgrad des Verbrennungsmotors steigern zu können. Gleichzeitig kann durch die gewonnene elektrische Energie beispielsweise eine Batterie des Kraftfahrzeuges aufgeladen werden, so dass die gewonnene elektrische Energie gespeichert und zu gegebener Zeit abgegeben werden kann, beispielsweise zur Erwärmung des Kühlmittels, um damit den Verbrennungsmotor schneller auf eine erforderliche Betriebstemperatur bringen zu können. Die dadurch gewonnene kürzere Warmlaufphase des Verbrennungsmotors spiegelt wiederum in einem geringeren Energieverbrauch, geringeren Schadstoffemissionen und einem erhöhten Wirkungsgrad nieder. Der zumindest eine erfindungsgemäß eingesetzte thermoelektrische Wandler dient somit nicht ausschließlich zur Gewinnung elektrischer Energie, sondern kann zugleich dazu benutzt werden, um aus bereitgestellter elektrischer Energie eine Kühlung bzw. eine Erwärmung des Kühlmittels zu erzeugen.The Invention is based on the general idea, in a conventional Internal combustion engine with a radiator for cooling of the internal combustion engine at this at least one thermoelectric To provide converter, which circulating in the radiator Coolant cools, heats or electrical Energy wins. As a result, the previously useless deflated and used by the internal combustion engine heat, in order to gain electrical energy and thereby the efficiency to increase the internal combustion engine. simultaneously can for example by the electrical energy obtained Battery of the motor vehicle to be charged, so that won electrical energy stored and delivered in due course can be, for example, for heating the coolant, in order to bring the internal combustion engine faster to a required operating temperature to be able to bring. The resulting shorter Warm-up phase of the internal combustion engine again reflects in one lower energy consumption, lower pollutant emissions and an increased efficiency down. The at least one thermoelectric used according to the invention Converter is thus not exclusively for recovery electrical energy, but can also be used to to cooled from supplied electrical energy cooling or to generate a heating of the coolant.
Bei einer vorteilhaften Weiterbildung der erfindungsgemäßen Lösung, ist der wenigstens eine thermoelektrische Wandler als sogenanntes Peltier-Element ausgebildet. Ein Peltier-Element basiert auf dem sogenannten Seebeck-Effekt, bei welchem bei Stromdurchfluss eine Temperaturdifferenz oder bei einer Temperaturdifferenz ein Stromfluss erzeugt wird. Grundlage derartiger Peltier- Elemente ist der Kontakt von zwei Halbleitern, welche ein unterschiedliches Energieniveau der Leitungsbänder besitzen. Leitet man einen Strom durch zwei hintereinanderliegende Kontaktstellen dieser Materialien, so muss auf der einen Kontaktstelle Wärmeenergie aufgenommen werden, damit ein Elektron in ein energetisch höheres Leitungsband des benachbarten Halbleitermaterials gelangen kann, wodurch es folglich zu einer Abkühlung kommt. Auf der anderen Kontaktstelle, fällt ein Elektron von einem höheren auf ein tieferes Energieniveau, so dass hier Energie in Form von Wärme abgegeben wird. Von besonderem Vorteil derartiger Peltier-Elemente sind deren geringe Größe sowie die Vermeidung jeglicher bewegter Bauteile, Gase und Flüssigkeiten, wobei durch eine simple Umkehr der Stromrichtung mit den Peltier-Elementen sowohl ein Kühlen als auch ein Heizen möglich ist. Aufgrund des geringen Bauraumbedarfs, können derartige Peltier-Elemente auch an äußerst schwer zugänglichen Stellen oder in stark zerklüfteten Bauräumen eingesetzt werden, so dass sich ein breites Anwendungsspektrum im modernen Fahrzeugbau bietet.at an advantageous embodiment of the invention Solution is the at least one thermoelectric converter designed as a so-called Peltier element. A Peltier element based on the so-called Seebeck effect, in which at current flow a temperature difference or at a temperature difference Current flow is generated. Basis of such Peltier elements the contact of two semiconductors, which have a different energy level own the conduction bands. Passing a current through two consecutive contact points of these materials, so must be absorbed on the one contact point heat energy, thus an electron in an energetically higher conduction band of the adjacent semiconductor material, whereby it consequently comes to a cool. At the other contact point, an electron falls from a higher to a lower one Energy level, so that here gives off energy in the form of heat becomes. Of particular advantage of such Peltier elements are their small size and the avoidance of any moving components, Gases and liquids, by a simple reversal the current direction with the Peltier elements both a cooling as well as heating is possible. Due to the low Space requirements, such Peltier elements can also in extremely hard to reach places or used in heavily rugged construction spaces be, so that a wide range of applications in the modern Vehicle construction offers.
