Abstract

L'invention concerne un régulateur thermique à changement d'état pourvu d'un milieu d'accumulation à changement de phase solide/liquide entouré par un matériau de mise en capsule. Ce régulateur est caractérisé par le fait qu'un métal ou un alliage de métal est utilisé comme milieu d'accumulation (5), que le matériau de mise en capsule (9) est résistant à la chaleur et stable par rapport au milieu d'accumulation et en par le fait que le matériau de mise en capsule (9) forme une matrice (3) pourvue de différents compartiments (4) dans lesquels le milieu d'accumulation (5) divisé en particules d'accumulation (7) séparées est contenu de manière étanche.
