Category.The combination of copper and mickel provides splendid electric conductivity and shield effectiveness.Conducting foam can in the frequency range of 100KHz to 1GHz
Obtain good shield effectiveness.
Conducting foam is particularly well-suited to capacity and the limited occasion of clossing pressure, and cost is relatively low, can extensive use
In electronic cabinet, casing, indoor cabinet, industrial equipment, notebook computer, mobile communication equipment etc..
But the heat dispersion of conducting foam is bad in the prior art, electronic equipment self performance is influenceed, and it is different
Receiving space can only place the conducting foam for matching specific thicknesses just with space, cause the inconvenience safeguarded and change.
The content of the invention
It is an object of the invention to overcome deficiency of the prior art, there is provided a kind of conducting foam, thermal diffusivity is improve
Can and multiple conducting foam can in any combination adapting to receiving space.
In order to solve the above technical problems, the invention provides a kind of conducting foam, it is characterized in that, including foam body, lead
Electric cloth and glue-line, a side of the foam body are provided with groove, and opposite flank is provided with can be with another foam sheet
The nested projection of the fit depressions of body, is provided with some dissipation hot holes through two opposite sides end face in foam body, described to lead
Electric cloth is close to the outer surface of the foam body by conducting resinl, and the glue-line is attached at the bottom of conductive fabric.
Further, the foam body is fire-retardant foam or suction ripple foam.
Further, the section of the louvre is I-shaped.
Further, the glue-line be conductive adhesive layer, and conductive adhesive layer refractive index less than conductive fabric refractive index.
Further, the thickness of the glue-line is 0.03 ~ 0.06mm.
Further, also it is pasted with mould release membrance in the bottom of glue-line.
Compared with prior art, the beneficial effect that is reached of the present invention is：The louvre that the present invention is set contributes to heat energy
Distribute, improve heat dispersion, reduce the temperature around itself and electronic equipment；Multiple conducting foams by it is raised with it is recessed
The cooperation of groove is combined, to adapt to different gap space, augmentation conducting foam range of application.Simple structure of the present invention, makes
Process is simple, easily promotes.
