Abstract

Le dispositif de chauffage (10) comporte un cadre de support (14) délimitant un passage pour les gaz, et au moins un élément conducteur (18) s'étendant entre deux extrémités et agencé dans le passage, chaque élément conducteur (18) étant relié à chacune de ses extrémités à une électrode (20) respective. Il comporte au moins une plaque (26, 28, 30) de support de chaque élément conducteur (18), solidarisée au cadre de support (14).The heater (10) comprises a support frame (14) defining a passage for the gases, and at least one conductive element (18) extending between two ends and arranged in the passage, each conductive element (18) being connected at each of its ends to a respective electrode (20). It comprises at least one support plate (26, 28, 30) for each conductive element (18), secured to the support frame (14).
