Description
Einrichtung zur Umwandlung von Wärmeenergie in elektrische Energie Für die Erzeugung elektrischer Energie ist es bekannt, die Permeabilität eines Eisenkreises mit eingeschalteten Induktionsspulen durch abwechselndes Erhitzen und Abkühlen der Eisenteile zu ändern. Zweckmäßig erfolgt die Temperaturänderung in der Weise, daß bei jedem Temperaturwechsel der Curiepunkt des Eisens durchlaufen wird, da in diesem Fall eine sprunghafte Permeabilitätsänderung auftritt. Es ist außerdem bekannt, für den magnetischen Kreis Eisenlegierungen zu verwenden, deren Curiepunkt bei verhältnismäßig niedrigen Temperaturen liegt. Gegenüber diesen bekannten Anordnungen bezieht sich die Erfindung auf eine besonders zweckmäßige Ausbildung der Energiequelle, welche die Temperaturänderungen im Eisenkreis hervorruft.Device for converting thermal energy into electrical energy The permeability of an iron circle is known for generating electrical energy with switched on induction coils by alternately heating and cooling the Change iron parts. The temperature change is expediently carried out in such a way that with every change in temperature the Curie point of iron is passed, since in this If a sudden change in permeability occurs. It is also known to use iron alloys for the magnetic circuit, the Curie point of which is relatively low temperatures. Relates to these known arrangements the invention to a particularly useful design of the energy source, which which causes temperature changes in the iron circle.
Gemäß der Erfindung sind mindestens die Teile des magnetischen Kreises mit stark temperaturabhängiger Permeabilität im Verbrennungsraum eines Explo@ sionsmotors für flüssige oder gasförmige Stoffe angeordnet. Als besonders vorteilhaft hat sich hierbei erwiesen, den magnetischen Kreis mit zwei parallel geschalteten und in entgegengesetztem Temperatursinn von der Wärmeenergie beeinflußten Schenkeln auszuführen, die aus einem Material mit stark temperaturabhängiger Permeabilität bestehen.According to the invention are at least the parts of the magnetic circuit with strongly temperature-dependent permeability in the combustion chamber of an explosion engine arranged for liquid or gaseous substances. Has proven to be particularly advantageous This proved the magnetic circuit with two connected in parallel and in opposite directions Temperature sense influenced by the heat energy to carry out the legs consist of a material with a highly temperature-dependent permeability.
Ein solcher magnetischer Kreis ist in der Zeichnung schematisch dargestellt. In der Mitte eines aus den Schenkeln 1 und 2 bestehenden Weicheisenjoches ist ein Dauermagnet 3 angeordnet. Die Schenkel 1 und 2 sind durch Einsatzstücke 4 und 5 aus einem ferromagnetischen Stoff, dessen Curiepunkt an der gewünschten Stelle liegt, unterbrochen. Die Einsatzstücke 4 und 5 werden nun im entgegengesetzten Temperatursinn von der Wärmeenergie beeinflußt, d. h., während beispielsweise das obere Stück 4 erhitzt wird, wird das untere abgekühlt, und umgekehrt.Such a magnetic circuit is shown schematically in the drawing. In the middle of a soft iron yoke consisting of legs 1 and 2 is a Permanent magnet 3 arranged. The legs 1 and 2 are through insert pieces 4 and 5 from a ferromagnetic material, the Curie point of which is at the desired point, interrupted. The inserts 4 and 5 are now in the opposite temperature sense influenced by the thermal energy, d. i.e., while for example the top piece 4 is heated, the lower one is cooled, and vice versa.
Die Wärmeenergie wird dabei durch eine periodische Verbrennung von flüssigen oder gasförmigen Stoffen erzeugt. Hierzu können Verbrennungsmotore bekannter Ausführung verwendet werden. Die ferromagnetischen Stoffe sind dabei innerhalb des Verbrennungsraumes angeordnet.The thermal energy is generated by a periodic combustion of generated liquid or gaseous substances. Internal combustion engines can be used for this purpose Execution are used. The ferromagnetic substances are within the Combustion chamber arranged.
