Description

Thermoelement, insbesondere für die elektrothermische Kälteerzeugung Die l?rfiiidttng hat sich die Aufgabe gestellt, ein Thermoelemettt zu schaffen, das eine große effektive Thermokraft ergibt und sich besonders vorteilhaft für die elektrothermische Kälteerzeugung eignet. Gemäß der Erfindung ist mindestens ein Schenkel des Elementes aus Carbiden gebildet. Vorteilhafte rweise kann hierbei der eine Schenkel aus Carbiden. z. B. aus Siliciumcarbid, bestehen, während der :indcrc Schenkel aus Kohle ge bildet ist. Gemäß der ueiteren Erfindung sind die leiden Schenkel des l:leme#iites lediglich durch Zusammen- drücken im kalten Zustand vereinigt. Es können auch beide Schenkel durch Pressen aus Pulver und Sintcrii hergestellt und hierbei gleichzeitig miteinander verbunden @\erdeii. Ferner ist es mög- lich, die 1x@iclcn Schenkel des Elementes vor ihrer Vereinigung mit einem dünnen Metallfilm, z. B. durch Aufdampfen, zu überziehen. Diese erfindungsgemäße Ausbildung des Elementes, insbesondere der Vereinigung ihrer beiden Schenkel, ergibt den großen Vorteil, daß an der Verbindungsstelle der beiden Schenkel ein äußerst geringer Kontaktwiderstand erreicht wird. Dies ist mit Rücksicht darauf, daß bei der elektrothermischen Kälteerzeugung große Stromstärken bei niedrigen Span. nungen erforderlich sind, von besonderer Bedeutung.Thermocouple, in particular for electrothermal cold generation The l? Rfiiidttng has set itself the task of to create a Thermoelemettt that is a big one effective thermopower results and especially advantageous for electrothermal refrigeration suitable. According to the invention is at least one Legs of the element formed from carbides. Advantageously, one of the legs can be used here made of carbides. z. B. made of silicon carbide, during the: indcrc legs made of coal forms is. According to the further invention, they are suffering Thighs of the l: leme # iites only by joining press united in the cold state. It can also both legs by pressing from powder and Sintcrii produced and at the same time connected to each other @ \ erdeii. It is also possible lich, the 1x @ iclcn leg of the element in front of their Association with a thin metal film, e.g. B. by vapor deposition to be coated. This inventive design of the element, in particular the union of its two legs, has the great advantage that an extremely low contact resistance is achieved at the junction of the two legs. This is in view of the fact that in electrothermal refrigeration, large currents at low span. are of particular importance.
