Abstract

L'invention concerne un noyau d'inductance comprenant : - un corps magnétique (400) comprenant une surface exposée (406), et formant un chemin magnétique médian (401a, 401b), - un drain thermique (410) compris dans le corps magnétique (400), le drain thermique (410) est une lamelle présentant une épaisseur, ladite lamelle présente une première conductivité selon la direction de son épaisseur, une seconde conductivité perpendiculairement à la direction de son épaisseur, la première conductivité étant inférieure à la seconde conductivité, la direction selon l'épaisseur est perpendiculaire au chemin magnétique médian (401a, 401b) dans le volume volumique du corps magnétique (400), la lamelle étant disposée de manière à drainer de la chaleur vers la surface exposée (406).The invention relates to an inductance core comprising: - a magnetic body (400) comprising an exposed surface (406), and forming a median magnetic path (401a, 401b), - a heat sink (410) included in the magnetic body (400), the heat sink (410) is a lamella having a thickness, said lamella has a first conductivity in the direction of its thickness, a second conductivity perpendicular to the direction of its thickness, the first conductivity being less than the second conductivity , the direction along the thickness is perpendicular to the median magnetic path (401a, 401b) in the volume volume of the magnetic body (400), the lamella being disposed so as to drain heat to the exposed surface (406).
