Abstract: A fire extinguishing device, comprising a support or base substrate, resistant to high temperatures and capable of being folded and/or shaped in three-dimensional form, on which, a predetermined thickness and preferably between 0.3 mm and 3 mm, a first homogeneous mixture comprising expanding graphite in a quantity of between 10% and 45%, a mono-component adhesive in a quantity between 45% and 75%, and other additives suitable to hinder the fire in a quantity between 1?1% and 20% or a second homogeneous mixture containing intumescent paint in a quantity between 70% and 95% and other additives suitable to hinder the fire in a quantity between 5% to 30% is deposited.

Abstract: A ventilation device for electrical panels, comprising a box-like metallic base (10), which is placed on top of an electrical panel and which has at least one lower opening (11) through which flows an air or heat flow (F) coming from said electrical panel, and at least one sheet or laminar element (12), preferably made of plastic material, placed above said box-like metallic base (10); a flap (13) is obtained in at least one portion of said laminar element (12), so that at least one portion of the perimeter of said flap (13) is made in one piece with said laminar element (12) and constitutes a linear fold (16) of said laminar element (12), suitable to allow said flap (13) raising and lowering with respect to said laminar element (12) for opening and closing a corresponding upper opening (15) of the laminar element (12) which is defined by said flap (13).
