Description
Die Erfindung betrifft einen Thermogenerator unter Ausnutzung des Seebeck-Effektes zur Erzeugung elektrischer Energie unter Ausnutzung der Temperaturdifferenz zwischen zwei Generatoroberflächen des Thermogenerators.The The invention relates to a thermogenerator utilizing the Seebeck effect for generating electrical energy by utilizing the temperature difference between two generator surfaces of the thermal generator.

derartiger Thermogenerator ist beispielsweise aus der Druckschrift
Aufgabe der vorliegenden Erfindung ist die Erzeugung eines elektrischen Stroms mit geringstmöglichen Mitteln bei sich zeitlich verändernden Umgebungstemperaturen.task The present invention is the generation of an electrical Current with the least possible means in time changing ambient temperatures.
Erfindungsgemäß wird diese Aufgabe durch die im Anspruch 1 angegebenen Merkmale gelöst. Weitere vorteilhafte Merkmale, Aspekte und Details der Erfindung ergeben sich aus den abhängigen Ansprüchen, der Beschreibung und der Zeichnungen.According to the invention this object is achieved by the features specified in claim 1. Further provide advantageous features, aspects and details of the invention from the dependent claims, the description and the drawings.
Die Erfindung ermöglicht die Ausnutzung sich zeitlich verändernder Umgebungsbedingungen, beispielsweise einer stetigen Erwärmung oder Abkühlung zur Erzeugung elektrischer Energie, die beispielsweise für Sensoren oder ähnliche Bauteile geringen Energiebedarfs benutzt werden kann. Dadurch wird die häufig aufwendige und anfällige Zuleitung elektrischer Energie über Kabel vermieden. Solche Bedingungen treten beispielsweise bei dem Steig- oder Sinkflug eines Flugzeuges auf, da in einer Höhe von über 10.000 Metern Temperaturen im Bereich von minus 50° bis 70° Celsius herrschen. Geht ein Flugzeug aus dieser Höhe bzw. bei dieser Temperatur in den Sinkflug über, so steigt dabei die Umgebungstemperatur bis hin zu den Bodentemperaturen. Die erfindungsgemäße Merkmalskombination dient nun dazu, dass die eine Generatoroberfläche den sich zeitlich verändernden Umgebungsbedingungen möglichst verzögerungsarm ausgesetzt wird, so dass diese Generatoroberfläche soweit wie möglich der Umgebungstemperatur entspricht oder folgt. Zugleich wird der Wärmefluß auf die zweite Generatoroberfläche soweit wie möglich behindert, um eine möglichst verzögerte Anpassung der Generatoroberflächentemperatur an die Umgebungstemperatur zu bewirken. Dadurch entsteht zwischen den beiden Generatoroberflächen eine Temperaturdifferenz, die wiederum zur Erzeugung elektrischer Energie solange nutzbar ist, bis auch die zweite Generatoroberfläche die Umgebungstemperatur dann näherungsweise erreicht.The Invention allows the utilization of temporally changing Environmental conditions, such as a steady warming or cooling to generate electrical energy, the for example, for sensors or similar components low energy requirement can be used. This will be the common consuming and vulnerable supply of electrical energy over Cable avoided. Such conditions occur, for example, in the climbing or descent of an aircraft, as at an altitude of over 10,000 meters temperatures ranging from minus 50 ° to 70 ° Celsius prevail. If an aircraft goes from this height or at this temperature in the descent over, so increases as well as the ambient temperature down to the floor temperatures. The inventive feature combination now serves In addition, the one generator surface is timed changing conditions as delay as possible is suspended so that this generator surface so far as possible corresponds or follows the ambient temperature. At the same time the heat flow to the second generator surface as much as possible hindered to one as possible delayed adaptation of the generator surface temperature to effect the ambient temperature. This creates between the two generator surfaces a temperature difference, which in turn can be used to generate electrical energy is, until the second generator surface, the ambient temperature then approximately reached.
Die Erfindung ermöglicht damit während der Phase sich zeitlich verändernder Umgebungsbedingungen (insbesondere Umgebungstemperaturen) die Erzeugung elektrischer Energie, die während dieser Betriebsphase dazu ausgenutzt werden kann, Verbraucher geringen Energiebedarfs wie Sensoren zu betreiben, die ohne externe Zuführungen elektrischen Stroms (z. B. Kabel) montiert werden können. Durch die Anbringung von Energiespeicherelementen wie Kondensatoren oder Akkumulatoren ist es auch möglich, einen Teil der nicht benutzten elektrischen Energie zwischen zu speichern.The Invention thus allows itself during the phase temporally changing environmental conditions (in particular Ambient temperatures) the generation of electrical energy during This operating phase can be exploited to consumers low Energy needs like to operate sensors without external feeders electric current (eg cables) can be mounted. By the attachment of energy storage elements such as capacitors or Accumulators it is also possible to part of the not to save used electrical energy between.
Vorzugsweise sind die ersten Mittel zur Bewirkung einer möglichst verzögerungsarmen Anpassung der ersten Generatoroberflächentemperatur an die Umgebungstemperatur eine Beschichtung geringer Wärmekapazität und/oder hoher Wärmeleitfähigkeit. Hierfür eignen sich insbesondere Materialien wie Titan, Aluminium, Kupfer, Gold, Silber oder Verbindungen bzw. Legierungen davon.Preferably are the first means of achieving a delay as possible Adaptation of the first generator surface temperature to the Ambient temperature a coating of low heat capacity and / or high thermal conductivity. Therefor In particular, materials such as titanium, aluminum, copper, Gold, silver or compounds or alloys thereof.
Gemäß einer vorteilhaften Weiterbildung der Erfindung sind oberflächenvergrößernde Elemente auf der ersten Generatoroberfläche vorgesehen, beispielsweise Wärmeleitrippen, die einen erhöhten Wärmefluß von der Umgebung in die erste Generatoroberfläche bewirken.According to one advantageous development of the invention are oberflächenvergrößernde Elements provided on the first generator surface, For example, heat fins that increased heat flow of cause the environment in the first generator surface.
Eine weitere vorteilhafte Ausbildung der Erfindung sieht vor, dass eine Beschichtung vorgesehen ist, die zumindest an der äußeren Umgebungsgrenzfläche zur Umgebung hin porös ist und dadurch eine erhöhte Oberfläche bewirkt, die einen verbesserten Wärmeaustausch zwischen Umgebung und erster Generatoroberfläche bewirken. Eine Weiterbildung dieses Erfindungsgedanken sieht vor, dass die Porösität von der Generatoroberfläche hin zur Umgebungsgrenzfläche zunimmt. Denn der Luftstrom durch die offenen Poren nimmt zur Tiefe hin immer mehr ab.A further advantageous embodiment of the invention provides that a coating is provided which is porous to the environment at least at the outer environmental boundary and thereby causes an increased surface, which effects improved heat exchange between the environment and the first generator surface. A development of this inventive concept provides that the porosity increases from the generator surface towards the environmental boundary. Because the air flow through the open pores decreases towards the depth more and more.
Die wärmeleitende Beschichtung wird vorzugsweise mittels Aufdampfen, Sputtern, Abscheiden aus der Gasphase, Aufbringen von Gemischen oder selektivem Ätzen, Laserbearbeitung oder Sintern aufgebracht.The thermally conductive coating is preferably by means of vapor deposition, Sputtering, deposition from the gas phase, application of mixtures or selective etching, laser processing or sintering applied.
Vorzugsweise umfassen die Mittel zur Verzögerung der Temperaturanpassung der zweiten Generatoroberfläche mindestens ein Wärmespeicherelement hoher Wärmekapazität, das zwischen der Generatoroberfläche und der Umgebungsgrenzfläche angeordnet ist. Vorzugsweise ist das Wärmespeicherelement nach außen zur Umgebungsgrenzfläche hin mit einer Schicht geringer Wärmeleitfähigkeit versehen, während zwischen dem Wärmespeicherelement und der Generatoroberfläche eine Schicht hoher Wärmeleitfähigkeit vorgesehen ist, um einen möglichst hohen Wärmeabfluß in Richtung des Thermogenerators zu erreichen, wobei dieser Wärmeabfluß durch den Wärmegenerator selber in Richtung der anderen, ersten Generatoroberfläche hin erfolgt.Preferably include the means for delaying the temperature adjustment the second generator surface at least one heat storage element high heat capacity, between the generator surface and the environmental interface is located. Preferably is the heat storage element to the outside to the surrounding boundary provided with a layer of low thermal conductivity, while between the heat storage element and the generator surface has a layer of high thermal conductivity is provided in order to maximize heat dissipation in Direction of the thermal generator to achieve, this heat flow through the heat generator itself in the direction of the other, first Generator surface out takes place.
Vorzugsweise besteht das Wärmespeicherelement aus Aluminium, Titan oder ein Verbindung bzw. Legierung dieser Elemente.Preferably consists of the heat storage element of aluminum, titanium or a compound or alloy of these elements.
Eine bevorzugte Weiterbildung der Erfindung sieht vor, dass die Schicht geringer Wärmeleitfähigkeit mindestens einen Hohlraum umfaßt, der entweder gasfrei (evakuiert) ist oder ein Gas niedrigen Druckes enthält und/oder mit Gas geringer Wärmeleitfähigkeit gefüllt ist, vorzugsweise mit Edelgas wie Argon.A preferred development of the invention provides that the layer low thermal conductivity at least one cavity which is either gas-free (evacuated) or a gas contains low pressure and / or with low thermal conductivity gas is filled, preferably with inert gas such as argon.
Eine alternative Ausführung des Wärmespeicherelementes besteht darin, dieses als Phasenwechselelement (PCM-Element) auszubilden, das Wärme über einen Phasenwechsel (z. B. fest in flüssig) speichert. Derartige Elemente verwenden vorzugsweise Salze, Salzhydrate oder deren Gemische oder organische Verbindungen wie z. B. Paraffin um Wärme zu speichern.A alternative embodiment of the heat storage element is to form this as a phase change element (PCM element), the heat through a phase change (eg in liquid) stores. Such elements preferably use Salts, salt hydrates or mixtures thereof or organic compounds such as B. Paraffin to store heat.
Um die Umgebungsbedingungen auf die erste Generatoroberfläche möglichst verzögerungsarm und intensiv einwirken zu lassen, ist es ferner bevorzugt, Strömungsleitflächen vorzusehen. Entsprechend entgegengesetzt wirkende Strömungsleitflächen zur Fernhaltung der schnellen Einwirkung Umgebungsbedingungen können nach einem weiteren Aspekt der Erfindung auch auf der anderen Seite des Thermogenerators vorgesehen werden.Around the environmental conditions on the first generator surface act as delay as possible and intensively it is further preferred to have flow control surfaces provided. Correspondingly oppositely acting flow control surfaces to keep away the rapid impact environmental conditions according to another aspect of the invention on the other side the thermogenerator can be provided.
Besonders bevorzugt ist die Anwendung der Erfindung an einem Luftfahrzeug, wobei vorzugsweise an einem ausfahrbaren Flugzeugfahrwerk ein Funksensor mit erfindungsgemäßen Thermogenerator zur Stromversorgung angebracht ist. Alternativ kann die Erfindung auch an einem Weltraumfahrzeug, z. B. einem Satelli ten oder einem Landefahrzeug angebracht werden, wobei dann die sich zeitlich verändernden Strahlungsbedingungen die Umgebungsbedingungen bilden, also die erste Generatoroberfläche der Strahlung ausgesetzt wird und die zweite Generatoroberfläche nicht. Auch an einem Unterwasserfahrzeug wie einem Unterseeboot kann die Erfindung vorgesehen werden, da die Wassertemperatur zumindest im oberflächennahen Bereich stark variiert.Especially preferred is the application of the invention to an aircraft, preferably on a retractable aircraft landing gear, a radio sensor with thermal generator according to the invention for power supply is appropriate. Alternatively, the invention may also be applied to a spacecraft, z. B. a satellites th or a lander mounted, then the time-varying radiation conditions form the ambient conditions, ie the first generator surface the radiation is exposed and the second generator surface Not. Also on an underwater vehicle like a submarine the invention can be provided since the water temperature at least varies greatly in the near-surface area.
