Including six side plates of up, down, left, right, before and after, back side panel and epipleural are provided with heat emission hole, and described dissipate is corresponded in case box
Hot hole is provided with radiator fan, is provided with sound insulation coaming plate around radiator fan, and sound insulation coaming plate takes the shape of the letter U setting, the opening alignment of U-shaped
The heat emission hole of back side panel is set, and six side plates be four-layer structure, and four-layer structure includes outermost metal shell layer and internal
Spaced mesh noise reduction layer, is additionally provided with foam sound-absorbing layer between mesh noise reduction layer and the metal shell layer, the foam is inhaled
Sound-absorbing layer inner and outer surfaces are provided with multiple spaced boss, are arranged at intervals between two layers of mesh noise reduction layer, are set in mesh noise reduction layer
There are multiple spaced bloops, the mutual stagger setting of bloop in two layers of mesh noise reduction layer.
Further optimization is as follows on the basis of such scheme：During the bloop aperture of the mesh noise reduction layer of innermost layer is more than
Between mesh noise reduction layer bloop aperture.
Further optimization is as follows on the basis of such scheme：Suction is additionally provided between each boss of foam sound-absorbing layer
Sound hole.
Further optimization is as follows on the basis of such scheme：The sound insulation coaming plate includes double layer of metal plate and is located at
Froth bed between double layer of metal plate in interlayer.
Further optimization is as follows on the basis of such scheme：The sound insulation coaming plate is connected by welding manner and right plate
Connect.
Above-mentioned technical proposal is employed, beneficial effects of the present invention are：The present invention, which provides one kind, can reduce calculating on a large scale
The Novel chassis of machine cabinet noise, by setting sound insulation coaming plate to provide first for the radiator fan of vibrations around radiator fan
Layer puigging, is then respectively provided with denoising structure, wherein being for innermost two layers aperture noise reduction on six side plates of case box
Layer, what is utilized is the principle of aperture noise reduction, significantly cuts down the energy of sound after aperture noise reduction twice, is then inhaled by foam
Sound-absorbing layer carries out further noise reduction, and what is utilized is the principle of impedance sound-absorbing, and the setting of foam noise reduction layer convex platform can make sound more
Secondary reflection reaches noise reduction purpose to consume the energy of sound, and noise-reduction structure can be significantly reduced in cabinet layer by layer more than
The unofficial biography energy of portion's noise so that cabinet can build quiet atmosphere with super-silent operation to people's working and learning.
