Abstract (en)
A thermally conductive and heating composite element (1; 50) comprising a laminar support layer (2; 51) provided with a first face (2a) adapted to remain facing towards the outside in application conditions, and with a second face (2b), opposite to the first face (2a), adapted to be coupled to a reference surface in application conditions, and a thermo-conductive and heating circuit (3; 52) of the electrical type, applied to the first face (2a) of the laminar support layer (2; 51), electrically connected to a very low voltage electrical power supply source comprised in the range of values from 3 Volts to 50 Volts, adapted to electrify the thermo-conductive circuit (3; 52) to produce heat. Particularly, in the thermally conductive and heating composite element (1; 50) of the invention, the thermo-conductive and heating circuit (3, 52) comprises at least one continuous resistive track (4) distributed on the first face (2a) of the laminar support layer (2; 51) and provided with a first end (4a), adapted to be coupled to a first electrical pole (P) of the electrical power supply source, and with a second end (4b) adapted to be coupled to a second electrical pole (N), having a polarity opposite to the polarity of the first electrical pole (P), of the electrical power supply source itself.
