Abstract

Le dispositif (1) de ventilation pour boîtier de batterie inclut un corps (2) de montage formant ou associé à une bordure d’ouverture du boîtier, un canal (C2) dans le corps, optionnellement une membrane (5) perméable obturant le canal, et un capot (3). Le canal guide un échappement gazeux provenant de l’intérieur du boîtier. Un média filtrant métallique (8 ; 108), typiquement à couche flexible fibreuse ou sous forme de textile, assure une protection anti-feu en se plaçant sous le corps (2) à l’opposé du capot, le média (8) incluant une toile ou couche flexible (ML) de fils ou fibres métalliques pour filtrer les gaz et séparer les particules solides. En obturant le canal (C2) par le dessous, le média (8) forme une barrière, thermiquement résistante, pour ne laisser passer dans le canal qu’un écoulement fluide épuré, sans particules solides, notamment lorsque la température de l’échappement gazeux dépasse 500°C.
