Abstract

Elément thermogénérateur dont on peut faire varier la température, comportant un corps (1) électroconducteur couplé à des électrodes (2) afin de véhiculer un courant par l'intermédiaire d'une couche (3) à caractéristiques de coefficient de température positif. Lorsque la température de la couche (3) présentant ces caractéristiques augmente jusqu'à se situer dans une plage déterminée de températures, la résistance électrique augmente soudainement de concert avec le coefficient de température positif de la couche (3) et le courant s'écoule de manière limitée dans le corps (1) de l'élément thermogénérateur et la température de ce dernier n'augmente pas davantage.
