Battery/CDROM severe environment heater casing having casing with thermal isolation and pocket having exothermal crystal mixture heating when shock wave mechanism activated.

摘要

The severe environment casing has a protection casing (1) with thermal isolation (2) in which is placed a pocket (3) with an exothermal crystal mixture (4). When a shock wave (7) is set by a mechanism (6) , reheating elements (5) inside the unit are heated by the exothermal reaction keeping the electronics units warm.
