Abstract
The invention provides a case. The case comprises a heat dissipation board in which a plurality of opening holes are formed, wherein a shielding cover which is covered on each opening hole incompletely is protruded on the opening hole towards the outer side of the case. The case can better shield electromagnetic radiation.
Description
Technical field
The present invention relates to a kind of cabinet.
Background technology
Computer frequency of utilization in people's life is more and more frequent.In long-term use, a series of problems that the user is brought because of being subjected to electromagnetic radiation pollution over a long time: fatiguability, decrease of memory, physiological function go down or the like and all can come one after another.
Shielding to electromagnetic radiation, generally can see through following method realize: select to have good ground connection outlet of the made cabinet of shield property, the closure that improves cabinet, design and perforate aperture reasonable in design etc., wherein the perforate on the cabinet also is used to satisfy the radiating requirements of cabinet.Please refer to Fig. 1 and Fig. 2, on existing cabinet 10, the perforate 12 on its heat sink 11 (front panel, side panel and rear panel all can) generally is designed to circle etc., and this plurality of opening 12 is used for the heat of cabinet 10 inside is distributed to the outside of cabinet 10.The aperture size of this perforate 12 also satisfies certain requirement, so makes perforate 12 can look after the radiating requirements of cabinet 10, can partly prevent irradiation of electromagnetic waves again.But its shield effectiveness to electromagnetic radiation still is not very good.
Summary of the invention
In view of above content, be necessary to provide a kind of cabinet of more effectively electromagnetic radiation shielding.
A kind of cabinet comprises a heat sink, has plurality of opening on the described heat sink, wherein establishes the screening cover of the described perforate of complete closed not to the lateral process of cabinet in each perforate.
A kind of cabinet, comprise a heat sink, have plurality of opening on the described heat sink, wherein said heat sink is also given prominence to the outside of cabinet along the periphery of each perforate a screening cover is set, each perforate comprises a first and a second portion, and wherein said first conductively-closed lid hides.
Above-mentioned cabinet sees through at tapping one screening cover that does not hide perforate fully is set, and makes cabinet satisfying under the situation that heat radiation requires more effectively electromagnetic radiation shielding.
Description of drawings
Fig. 1 is the synoptic diagram of existing cabinet.
Fig. 2 is the partial perspective view of heat sink among Fig. 1.
Fig. 3 is the partial perspective view of heat sink of the better embodiment of cabinet of the present invention.
Fig. 4 is the side view of heat sink among Fig. 3.
Fig. 5 is the electromagnetic radiation screening rate analog result comparison diagram of existing cabinet among cabinet of the present invention and Fig. 1.
The main element symbol description
Heat sink 2,11
Perforate 3,12
Embodiment
Below in conjunction with accompanying drawing and better embodiment the present invention is described in further detail:
Please refer to Fig. 3 and Fig. 4, the better embodiment of cabinet of the present invention is a rectangular parallelepiped, and it comprises a heat sink 2, and this heat sink 2 can be any panel of cabinet, as front panel or side panel etc.Has plurality of opening 3 on this heat sink 2.This heat sink 2 is given prominence to the outside of cabinet along the periphery of each perforate 3 screening cover 4 is set.This screening cover 4 is an arch.This plurality of opening 3 is all rounded, and comprises the second portion that a first and conductively-closed lid 4 hide.That is to say that this screening cover 4 does not hide described perforate 3 fully.So, this perforate 3 still is connected with cabinet inside, thereby the heat of cabinet inside can be distributed to the outside of cabinet, to satisfy the radiating requirements of cabinet.
Please refer to Fig. 5, wherein have the electromagnetic radiation screening rate analog result figure of cabinet 10 in curve A 1 representative graph 1 now, the electromagnetic radiation screening rate analog result figure of cabinet of the present invention in curve A 2 representative graphs 3.As can be seen from Figure 5, the electromagnetic radiation screening rate of cabinet is better than the electromagnetic radiation screening rate of existing cabinet 10 among Fig. 1 among Fig. 3.When frequency was 4GHz, the electromagnetic radiation screening rate of cabinet had the screening rate more than the 2.1dB to improve than the electromagnetic radiation screening rate of cabinet among Fig. 1 10 among Fig. 3.
In addition, the big I of this screening cover 4 changes according to deviser's needs.And in other embodiment, the shape of this perforate 3 and screening cover 4 also can be other shape, as square etc.
Claims (6)
1. a cabinet comprises a heat sink, has plurality of opening on the described heat sink, it is characterized in that: establish the screening cover of the described perforate of complete closed not to the lateral process of cabinet in each perforate.
2. cabinet as claimed in claim 1 is characterized in that: described plurality of opening is all rounded.
3. cabinet as claimed in claim 1 is characterized in that: described screening cover is an arch.
4. cabinet, comprise a heat sink, has plurality of opening on the described heat sink, it is characterized in that: described heat sink is also given prominence to the outside of cabinet along the periphery of each perforate a screening cover is set, each perforate comprises a first and a second portion, and wherein said first conductively-closed lid hides.
5. cabinet as claimed in claim 4 is characterized in that: described plurality of opening is all rounded.
6. cabinet as claimed in claim 4 is characterized in that: described screening cover is an arch.
