L'invention est caractérisée en ce qu'au moins un système de chauffe est disposé dans le carter, de façon que les plans de grille des éléments de grille soient disposés sensiblement perpendiculairement à la direction longitudinale, de façon que le courant du milieu soit dirigé sensiblement perpendiculairement aux plans des grilles, et en ce que les éléments de grille et au moins un élément de chauffe sont disposés serrés entre eux à leur contact, au moyen d'au moins un élément de serrage, et en ce que les éléments de grille présentent, respectivement, au moins une zone de contact et sont disposés de façon qu'ils absorbent l'énergie thermique provenant d'au moins un élément de chauffe, essentiellement via la zone de contact. Le dispositif de chauffe est d'une fabrication simplifiée et peut être fabriqué à moindre frais, tout en tenant compte de l'aspect protection de l'environnement, également lors du fonctionnement du dispositif de chauffe.
