Safety housing for protecting electronic devices, has connection between shell, plate, heat sink and cooling laminates that loses heat transfer properties if ambient temperature exceeds certain limit, such that connection reaches state

摘要

The housing has an inner shell (5) of a chamber wall, where a connection between the shell, a heat spreading plate, a heat sink (23) and cooling laminates transfers heat. The connection has a heat transfer property that is more than heat transfer properties of heat insulation material (15) and a heat insulation wall conducting heat absorbed by the shell and plate to the sink and laminates. The connection loses the properties if ambient temperature exceeds a certain limit, so that the connection reaches a state after the temperature exceeds the limit and properties are lower in the state.
