Description
Technical field
The utility model relates to a kind of electromagnetic shielding equipment, and in particular to a kind of micropore alloy-type electromagnetic shielding rack belongs to
In technical field of electric equipment.
Background technique
Electromagnetic shielding refers to is isolated between two or more area of space, to prevent the electric field in one of region
With magnetic field to external diffusion, while preventing the electric and magnetic fields in other regions from interfering the region.It is much used for electronics at present
Or the cabinet of electrical control requires to be electromagnetically shielded, the purpose is to prevent in cabinet, cabinet exoelectron equipment carry out electricity between each other
The stability and reliability of especially cabinet inner electronic equipment inside and outside cabinet are reinforced in magnetic disturbance.
Traditional electromagnetic shielding equipment is usually the hexahedron steel construction being welded by cold-rolled steel sheet, and structure bulky is not easy
It carries and transports.In addition to ensuring the shielding properties of traditional magnetic shield apparatus, interior design is relatively closed space,
But with the development of network server, the power of network server is increasing, heat dissipation problem just becomes restriction electromagnetic shielding
The bottleneck of equipment development.
Utility model content
The utility model aim is for above-mentioned problem of the existing technology, provides a kind of light-weight, is both able to satisfy
Electromagnetic shielding requirements, and it is able to achieve the micropore alloy-type electromagnetic shielding rack from heat dissipation.
In order to reach the goals above, the utility model provides a kind of micropore alloy-type electromagnetic shielding rack, including has
The cabinet body of electro-magnetic screen function is equipped with cabinet door on the cabinet body, and the cabinet body is by cabinet board group at the cabinet plate includes left cabinet
Plate, right cabinet plate, upper cabinet plate, lower cabinet plate and rear cabinet plate, it is close on the left cabinet plate, right cabinet plate, upper cabinet plate, lower cabinet plate and rear cabinet plate
It is furnished with micropore, signal cut-off filter is provided in the cabinet body, several signal cut-off waveguides are provided on the cabinet body.
Technical solutions of the utility model are further defined to, the cabinet body be equipped with opening, the size of the opening with
The signal cut-off waveguide matches.
Further, the opening is arranged on upper cabinet plate.
Further, the cabinet plate, cabinet door material be sheet alloy.
Still further, the sheet alloy with a thickness of 2mm.
Further, gather micropore on the sheet alloy, and the aperture of the micropore is 0.15mm.
The beneficial effects of the utility model are as follows: the utility model shields cabinet shell using the preparation of micropore sheet alloy,
Make electromagnetic shielding rack weight be only traditional cabinet 20%-25%, solve shielding cabinet transport and difficult asked
Topic, while micropore sheet alloy had not only been able to satisfy the requirement of electromagnetic shielding but also had realized the function from heat dissipation, was ensureing interior of equipment cabinet
Energy-saving and emission-reduction are achieved the purpose that while equipment operational safety.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram of micropore sheet alloy in the utility model.
In figure: 1. cabinet bodies, 2. cabinet doors, 3. micropores.
The utility model is further described with reference to the accompanying drawings and examples.
Embodiment 1
A kind of micropore alloy-type electromagnetic shielding rack is present embodiments provided, structure is as shown in Figure 1, include having electromagnetism
The cabinet body 1 of function of shielding is equipped with cabinet door 2 on cabinet body 1, and cabinet body 1 is by cabinet board group at cabinet plate includes left cabinet plate, right cabinet plate, upper cabinet
Plate, lower cabinet plate and rear cabinet plate, are densely covered with micropore 3 on left cabinet plate, right cabinet plate, upper cabinet plate, lower cabinet plate and rear cabinet plate, in cabinet body 1
It is provided with high performance signal cut-off filter, several signal cut-off waveguides are provided on cabinet body 1.On the upper cabinet plate of cabinet body 1
Equipped with opening, size and the signal cut-off waveguide of opening match.
In addition, as shown in Fig. 2, the material of cabinet plate, cabinet door 2 be sheet alloy, sheet alloy with a thickness of 2mm, alloy sheets
Gather micropore 3 on material, and the aperture of micropore 3 is 0.15mm.
In actual use, the case material selection for shielding cabinet depends on frequency of use range and wants to shield effectiveness
It asks.In general, the conductivity of conductor is higher, and frequency is higher, and the vortex of generation is bigger, and skin depth is smaller, shielding thickness
It can be thinner.According to the thickness of required attenuation by absorption amount you can get it shielded layer.For the convenience calculated, it is assumed that: A=
80dB, μ r=1, r=1 σ, then as frequency f=1MHz, shielding thickness d are as follows:
By calculating it is found that when shield effectiveness is 80dB, it is only necessary to the sheet metal of 0.61mm thickness.If reflection loss is examined
Including worry, then required shielding thickness is smaller.The present embodiment selects the micropore alloy of 2mm thickness to be entirely capable of as shielding material
Enough meet shielding properties requirement.
As described above, although the utility model has been indicated and described referring to specific preferred embodiment, it must not
It is construed to the limitation to the utility model itself.In the spirit and scope for not departing from the utility model that appended claims define
Under the premise of, it can various changes can be made in the form and details to it.
