Panel ( 10 ) for generating and diffusing heat obtained from a heat-radiating board ( 30 ) comprising one or more pieces of electrothermal fabric, with strips of fibreglass laid side by side to form the warp, the weft ( 50 ) consisting of a continuous copper wire ( 51 ), small in diameter and of considerable length, coated with insulating material, that extends serpentinewise passing alternatively above and below the strips of fibreglass, said board ( 30 ) being completed by intermediate and external layers ( 35, 36 ) of epoxidic thermoadhesive material and clad on both surfaces with sheets of micanite ( 31, 32 ), so that on connecting the ends of the wire ( 51 ) forming the weft ( 50 ) to a source of electric current, boring holes ( 65, 66 ) using means, that may be a laser beam, on the thermoadhesive layer ( 35, 36 ) covering the weft ( 50 ), this latter converts electric energy into thermal energy. |
