Abstract (en)
[origin: WO2017125690A1] The invention concerns a device (1) in the form of a complex comprising: a layer of elastically compressible foam (2) comprising first (3) and second (4) faces that are, respectively, adhesive, said layer having a thickness of between 0.5 and 2 mm; a heavy layer (5) made from polymer material in which a powder filler is dispersed, said layer being associated with said first face, said foam layer having a thermal conductivity, at 25 °C, greater than or equal to 0.02 W/m.K; said heavy layer having a mass per unit area of between 2.5 and 10 kg/m2 and an overall thickness (8) of between 1.5 and 10.5 mm, the filler content by volume being between 20 and 55%, the thermal conductivity of said filler, at 25 °C, being greater than 100 W/m.K.
