ABSTRACT:
A crash-survivable enclosure (10) for protecting a data memory unit (45) used in vehicles has a shell (15) with an inner surface (22). The shell (15) defines an interior cavity (26) which contains the data memory unit (45). The enclosure (10) has a heat absorption composition (20) which lines a portion of the inner surface (22) and substantially surrounds the data memory unit (45). The composition is capable of exhibiting an endothermic phase transition when subjected to a high temperature environment. The phase transition is typically from a solid phase to a non-solid, flowable phase. The shell can also have a plurality of vents (42). The vents (42) are sized and positioned to permit the heat absorption material (20) to drain from the shell when in the non-solid, flowable phase. The vents (42) can be positioned such that the flowable heat absorption material will drain regardless of the orientation of the shell (15).
