Envelope for forming complete case to protect e.g. lithium-ion battery tray, in car, has full wall partially surrounding electrical equipment, where zone of wall includes thermoplastic polymer surrounding porous metal insert
The envelope (1) has two identical parts (2, 3) including respective bottoms (4, 5) surmounted by four perpendicular sides with constant height. The sides define a rectangle. A full wall partially surrounds an electrical equipment, where a zone (61) of the wall includes polymer i.e. thermoplastic polymer, surrounding a porous metal insert. The polymer is molded on the insert. The insert is a mesh consisting of a set of intersecting metal yarns, a plate comprising a set of systematically and homogeneously distributed identical openings and a foam.
