Layer is penetrated, the isolation layer is folded among electromagnetic absorption layer and shielding reflecting layer, the electromagnetic absorption layer opposite direction box house, institute
It states outside shielding reflecting layer opposite direction cabinet；Ventilation opening is offered on the top plate, is provided on the peripheral wall of the ventilation opening
One circle electromagnetic absorption siding, is provided with shielding case on the ventilation opening.
Further, the shielding reflecting layer includes substrate I and reflectance coating, the reflectance coating is laid on the outside of substrate I
On surface；The electromagnetic absorption layer includes substrate II and screened film, and the screened film is laid on II inner surface of substrate；It is described
Isolation layer is the vacuum interlayer constituted between substrate I and substrate II, can guarantee to completely cut off effect, prevent shielding reflecting layer and electricity
It generates and influences each other between magnetic absorption layer, improve effectiveness.
Further, the shielding case is arc-shaped structure；Electromagnetic wave effectively at shielding heat dissipation.
Further, the electromagnetic absorption siding surrounds as up-narrow and down-wide bench-type channel；It is oriented to electromagnetic wave absorption, is increased
Strong shield effectiveness.
Using the technical program the utility model has the advantages that
Bottom plate, which is arranged to solid slab, in the present invention enables electric cabinet to be stably fixed on ground or desktop etc.；
All sidings are arranged to include that electromagnetic absorption layer, isolation layer and the electromagnetic absorber that sticks of shielding reflecting layer electromagnetic absorption layer have
Effect absorbs the electromagnetic wave that box house electrical equipment generates, the effective reflective box of ELECTROMAGNETIC REFLECTION material sticked by shielding reflecting layer
The electromagnetic wave that body external radiation is come, passes through influencing each other for isolation layer both sides effectively at different levels；By being offered on the top plate
Ventilation opening is provided with shielding case on the ventilation opening, ensure that while guaranteeing box house electrical equipment ventilation and heat
Shielding electromagnetic waves effect.
The utility model can effectively prevent electromagnetic wave pollution caused by the external world that electrical equipment issues in electric cabinet, prevent
Only influence on system operation of the external electromagnetic wave to internal electrical equipment；Electric equipment operation effect is improved, safety, guarantor are improved
Body health.
