Abstract
Dispositif de déshumidification (1) d'un boîtier fermé (2).Le dispositif de déshumidification (1) comprend un caisson (3) comprenant une entrée (5) communiquant avec l'intérieur du boîtier fermé (2) et une sortie (6), un module de chauffage apte à être commandé pour générer de la chaleur, un déshydratant (8) configuré pour adsorber l'humidité lorsqu'il n'est pas chauffé par le module de chauffage (7) et pour restituer l'humidité adsorbée par désorption lorsqu'il est chauffé par le module de chauffage (7), un bouchon mobile (9) pouvant être déplacé pour ouvrir et fermer alternativement l'entrée (5) et la sortie (6), un ressort de rappel (10) configuré pour déplacer le bouchon mobile (9) lorsque le module de chauffage (7) ne chauffe pas le déshydratant (8) et un ressort (11) en alliage à mémoire de forme configuré pour déplacer le bouchon mobile (9) lorsque le module de chauffage (7) chauffe le déshydratant (8), ledit ressort (11) en alliage à mémoire de forme pouvant être chauffé par le module de chauffage (7) en même temps que le déshydratant (8). Le dispositif de déshumidification (1) est adapté à la déshumidification de tout type de boîtier fermé, il est économique tant au niveau de la conception que de la consommation électrique, et il est facile à mettre en œuvre grâce à sa petite taille et à sa conception simple.
