Abstract

Un appareil de chauffage électrique résistant à l'eau comprend une enveloppe métallique (1) et un corps chauffant (2) disposé à l'intérieur d'une cavité de l'enveloppe. Une section de conducteur linéaire (3) est disposée au niveau de deux côtés du corps chauffant (2), respectivement. Le corps chauffant (2) et le conducteur linéaire (3) sont tous deux disposés dans un tube de protection (5). Des déflecteurs (4) sont disposés à l'extérieur du tube de protection (5) au niveau de deux côtés du corps chauffant (2), et une zone chauffante est formée à l'intérieur de la cavité située entre les deux déflecteurs (4). Des revêtements de caoutchouc (7) pour l'étanchéité sont disposés au niveau de deux extrémités latérales du tube de protection (5). Le tube de protection (5) est supporté et fixé dans la cavité de l'enveloppe métallique par des plaques de support (6) montées au niveau de deux côtés de celle-ci. Des zones de refroidissement sont formées à l'intérieur de cavités situées entre les déflecteurs (4) et les plaques de support (6). Des joints des conducteurs linéaires (3) et un fil externe (12) sont enfermés dans les revêtements de caoutchouc.
