Abstract
Le dispositif de comporte : - un élément (18) de chauffage électrique, - des moyens d'alimentation de l'élément de chauffage (18) en électricité, et - un boîtier, dans lequel l'élément de chauffage (18) est destiné à être agencé. Le boîtier présente une section transversale définie par un contour de boîtier, et le dispositif de chauffage (10) comporte un support (22) pour l'élément de chauffage (18), ledit support (22) présentant un contour extérieur (22a) complémentaire du contour du boîtier (12), et un contour intérieur (22b) complémentaire de l'élément de chauffage (18).The device comprises: - an electric heating element (18), - means for supplying the heating element (18) with electricity, and - a housing, in which the heating element (18) is intended to be arranged. The housing has a cross section defined by a housing outline, and the heater (10) has a support (22) for the heating element (18), said support (22) having a complementary outer contour (22a) of the contour of the housing (12), and an interior contour (22b) complementary to the heating element (18).
