Abstract:
1. A desiccant device for use in an enclosure protecting sensitive electronic equipment, comprising: the desiccant device enclosing a desiccant material, wherein the desiccant device permits water to diffuse from the interior of the hard-disk drive into the desiccant device at a faster diffusion rate than water is permitted to diffuse out of the desiccant device into the interior of the hard-disk drive, wherein the desiccant device comprises no channels between the exterior of the desiccant device and the interior of the desiccant device, wherein the desiccant device is constructed using a laminate material, wherein the laminate material comprises (a) an exterior facing material which is exposed to the interior of the hard-disk drive and is not exposed to the interior of the desiccant device, and (b) an interior facing material which is exposed to the interior of the desiccant device and is not exposed to the interior of the hard-disk drive, and wherein the exterior facing material permits water to diffuse faster therethrough than the interior facing material, wherein the laminate material comprises an inner layer that is disposed between the exterior facing material and the interior facing material, and wherein the inner layer is composed of dense non-woven fabric.
