Schott wall device absorbing thermal energy

摘要

Sandwich-like layered bulkhead wall device (100) for at least partially enveloping a given space of a vehicle in order to reduce thermal heating of the given space when exposed to heat from the outside, with a core element (110) arranged between two cladding elements (120, 130), wherein the core element (110) is formed by a cavity at least partially filled with zeolite minerals, characterized in that a melting process of zeolite minerals is designed as an endothermic, i.e. thermal energy consuming phase transition, in which the thermal energy necessary for the melting process is introduced into the zeolite minerals and is thereby withdrawn from the ambient environment, and- the zeolite minerals are selected in order to carry out a phase transition from solid to liquid which absorbs thermal energy at a predetermined temperature, in order for the duration of the phase transition from solid to liquid r relevant zeolite minerals a very effective reduction of a temperature rise in a room area of a vehicle to be protected by means of the bulkhead wall device according to the invention to such an extent that the temperatures in these room areas do not exceed predetermined maximum values when exposed to heat from the outside due to fire or other cause exceed, wherein the zeolite minerals are filled in liquid-tight bags with a size in the range of 50 mm x 50 mm to 100 mm x 100 mm.
