Description
Einrichtung zur Erzeugung von Induktionsströmen aus Wärme, vermittels der bei Einwirkung von Wärmeschwankungen auf einen magnetischen Körper in ihm auftretenden Änderung des Magnetismus Es ist bekannt, daß gewisse Körper, so vorzugsweise die ferromagnetischen Metalle, unter der Wirkung magnetischer Kraftfelder selber magnetisch werden. Weiter ist bekannt, daß auf diese Weise oder auf andere Art magnetisch gewordene Substanzen ihren Magnetismus nicht durch alle Temperaturgrade hindurch behalten, sondern von einer gewissen Temperatur ab, teils schneller, teils langsamer, ihren Magnetismus mehr oder minder wieder aufgeben bzw. ganz verlieren, um ihn mit fallender Temperatur gegebenenfalls ganz oder teilweise wieder zu erlangen.Device for generating induction currents from heat, mediated that which occurs when a magnetic body is exposed to fluctuations in temperature Change in magnetism It is known that certain bodies, preferably the ferromagnetic metals, themselves magnetic under the effect of magnetic force fields will. It is also known that in this way or in another way become magnetic Substances do not retain their magnetism through all temperature degrees, but from a certain temperature, sometimes faster, sometimes slower, theirs To give up magnetism more or less again or to completely lose it with falling To regain the temperature in whole or in part if necessary.
Man hat diese Eigenschaft, den Magnetismus von Eisen durch Einwirkung von Wärmeschwankungen zu ändern, bereits zur Erzeugung von Induktionsströmen benutzt.One has this property, the magnetism of iron through action to change from thermal fluctuations, already used to generate induction currents.
Es wurde nun gefunden, daß man eine wesentliche Verbesserung der Ökonomie derartiger Einrichtungen dadurch erhält, daß man als magnetisches Material nicht Eisen verwendet, sondern solche Legierungen an sich bekannter Art, die schon bei geringen Temperaturerhöhungen scharfe Schwankungen im Magnetismus aufweisen. Die zur Erzeugung des gleichen Stromes durch Änder ung des Magnetismus erforderliche Wärmemenge wird dadurch wesentlich geringer als bei Verwendung von Eisen. Gegenüber dem Eisen, das erst bei etwa 7oo° seinen Magnetismus verliert, bietet gerade die Verwendung solcherLegierungen, die schon bei tiefen Temperaturen ihren Magnetismus abgeben, wie dies z. B. die Heuslerschen Legierungen und andere tun, erhebliche Vorteile. Der verhältnismäßig kleine Einzeleffekt kann im Bedarfsfalle durch eine Vielheit von Einzelapparaturen in geeigneter Zusammenschaltung gesteigert werden.It has now been found that there is a substantial improvement in the economy such devices obtained by not using a magnetic material Iron is used, but such alloys of a known type, which are already used in small increases in temperature have sharp fluctuations in magnetism. the to generate the same current by changing the magnetism As a result, the amount of heat is considerably less than when using iron. Opposite to iron, which only loses its magnetism at about 700 °, offers precisely this Use of such alloys, which have their magnetism even at low temperatures submit, as z. B. Heusler's alloys and others do significant Advantages. The relatively small individual effect can, if necessary, by a The multiplicity of individual apparatuses can be increased in suitable interconnection.
