  • Patent number: 6158833
    Abstract: A thermally insulated cabinet is provided for protecting electronic data storage devices from damage by accidental and environmental conditions and from intentional acts. This cabinet provides an interior envelope which contains a data storage device surrounded by multiple layers of thermal insulation. The thermal insulation layers allow electrical power, data and device control cabling to access the device, thus permitting real time operation of the device while the device is contained within the inner envelope. The inner envelope has two vertically separated ends: a lower end and an upper end. The data storage device is affixed to the inner envelope to permit heated air to rise from the lower end of the inner envelope away from the location of the device. The inner chamber is dimensioned to permit the heat generated by operation of the data storage device to dissipate and to maintain stable thermal conditions within the inner envelope during normal use.
