Abstract

L'invention concerne un dispositif d'atomisation électronique, son atomiseur (1) et un noyau d'atomisation (12, 12v, 12c, 12d), le noyau d'atomisation (12, 12v, 12c, 12d) comprenant un corps d'absorption de liquide et un élément chauffant (122, 122v, 122e, 122p) qui est disposé sur le corps d'absorption de liquide. L'élément chauffant (122, 122v, 122e, 122p) comprend des parties chauffantes (1223, 1223v), et les parties chauffantes (1223, 1223v) comprennent une pluralité de points chauds, la pluralité de points chauds étant agencés dans une matrice de points. Du fait de la fourniture d'une piste d'atomisation de type à matrice de points, la température des points chauds peut être rapidement augmentée pour obtenir l'atomisation rapide d'une matrice générant un aérosol liquide, et la chaleur peut être conduite dans de multiples directions pour empêcher l'accumulation de chaleur et l'apparition d'un état de surchauffe.
