Title
(EN) ELECTRONIC BREATHER BAG FILTER
(FR) FILTRE COMPORTANT UNE POCHE DE RESPIRATION, POUR BOITIER ELECTRONIQUE
Abstract
(EN) A breather bag filter assembly for use with an electronic enclosure, such as a hard disk drive enclosure containing a rotating disk, is disclosed. The filter assembly provides filtration of air entering and exiting an electronic enclosure through a breather hole. The filter assembly is a deformable sealed cavity that exchanges air with the drive enclosure as the air pressure inside the drive enclosure fluctuates. In one implementation of the invention the filter assembly contains three layers of material. Two layers of material form the exterior of the filter assembly surrounding a third layer that is composed of an adsorbent material.
(FR) L'invention concerne un filtre comportant une poche de respiration, destiné à être utilisé avec un boîtier électronique, tel qu'un boîtier de lecteur de disque dur contenant un disque rotatif. Ce filtre permet de filtrer l'air qui entre et qui sort d'un boîtier électronique par un orifice d'aération. Le filtre comprend une cavité étanche souple qui échange de l'air avec le boîtier du lecteur de disque dur en fonction des variations de pression de l'air à l'intérieur du boîtier du lecteur de disque dur. Dans un mode de réalisation, le filtre se compose de trois couches de matériau. Deux de ces couches forment l'extérieur du filtre et enveloppent une troisième couche constituée d'un matériau adsorbant.
