Abstract

L’invention concerne un dispositif d’induction électromagnétique pourvu d’un entrefer variable doté de moyens de dissipation de chaleur. En particulier, le dispositif selon la présente invention comprend un noyau au niveau duquel est logé l’entrefer variable. Ledit entrefer comprend par ailleurs des premières plaques ferromagnétiques destinées à guider un flux magnétique susceptible de prendre naissance dans le noyau et de présenter de manière collective un champ magnétique de saturation inférieur à celui du noyau. L’entrefer variable selon les termes de la présente invention comprend en outre des protubérances latérales formant les moyens de dissipation de chaleur et qui s’étendent à partir de faces latérales des premières plaques. Figure pour l’abrégé : Figure 2 .The invention relates to an electromagnetic induction device provided with a variable air gap provided with heat dissipation means. In particular, the device according to the present invention comprises a core at which the variable air gap is housed. Said air gap furthermore comprises first ferromagnetic plates intended to guide a magnetic flux capable of originating in the core and of collectively presenting a saturation magnetic field lower than that of the core. The variable air gap according to the terms of the present invention further comprises side protrusions forming the heat dissipating means and which extend from side faces of the first plates. Figure for the abstract: Figure 2.
