Protection container

摘要

A protection container is described having an internal accommodation space for an electrical circuit arrangement which is intended to be protected against high outside temperatures and against destruction. The accommodation space is surrounded by an inner insulation chamber to which an outer insulation chamber is connected, at a distance. The inner insulation chamber is filled with melted solder and the outer insulation chamber with water. The melting temperature of the melted solder is lower than the boiling temperature of the water so that, in the case of high outside temperatures, the water boils and the melted solder becomes liquid. During this time period, the internal temperature in the accommodation space is held at a temperature level which is acceptable for the circuit arrangement which is located therein.
