Magnetic storage device with multi-functional component for controlling chemical and water vapor therein

摘要

Approaches for desiccant device within an enclosure protecting sensitive electronic equipment. Electronic equipment, such as a hard-disk drive (HDD), may comprise a desiccant device a desiccant device that comprises a first desiccant material, a second desiccant material, and an activated carbon layer. The first desiccant material has a relatively high rate of water vapor absorption while the second desiccant material has a relatively low rate of water vapor absorption. The activated carbon layer absorbs airborne organic airborne particles. The desiccant device may be a breather filer or may be disposed entirely within the interior of the electronic equipment, e.g., the desiccant device may be a recirculation filter.

主权项

1. A desiccant device for use in an enclosure protecting sensitive electronic equipment, comprising:
the desiccant device comprising a first desiccant material, a second desiccant material, and an activated carbon layer, wherein the first desiccant material has a high rate of water vapor absorption, wherein the second desiccant material has a low rate of water vapor absorption, wherein the activated carbon layer absorbs airborne organic vapor, and wherein the water diffusion rate from the interior of the desiccant device to the interior of the enclosure matches or is substantially similar to the water vapor permeability rate of the enclosure.
