Abstract
The structure comprises following parts: there are vent holes for discharging hot sir on back cover of the panel display. Cooling fan is setup on side of the vent holes at inner side of main body. Mounting groove is arranged around periphery of back cover with vent holes. Noise absorption pad is put inside the mounting groove. The structure makes display cooling effectively and cuts off noise effectively.
Description
Technical field
The present invention relates to the flat-panel screens technology, particularly a kind of flat-panel screens noise-proof structure that can be reduced in generation noise in the flat-panel screens to greatest extent.
Background technology
Plasma display (being PDP) is slim big picture, can present the second best in quality picture.Because these advantages, its range of application enlarge rapidly, particularly use a lot in public places.On the other hand, owing to the reduction of price, plasma display begins to enter family recently, and this has become a kind of trend.
, the PDP picture reappears according to isoionic occurring principle to be realized, and isoionic generation must be followed the generation of a large amount of heats, so rapidly outside distribute heat is an important topic.
Fig. 1 is the heat-dissipating structure of explanation traditional PD P.Referring to Fig. 1, the heat-dissipating structure of traditional PDP10 comprises: the certain position of bonnet 11 is provided with the air vent hole that can make the inside and outside circulation of air of PDP 12 of a plurality of grating structures etc. overleaf.Like this, connect the inside and outside air vent hole 12 of PDP and be arranged on PDP bonnet 11, outside the heat discharge machine that produces when PDP is worked.Simultaneously, in air vent hole 12, be positioned at fuselage one side and be provided with cooling fan, hot-air is forced row to the outside.
Fig. 2 represents the PDP heat-dissipating structure sectional drawing of conventional art.Referring to Fig. 2, this radiator structure comprises: PDP10; Bonnet 11; Be arranged at the air vent hole 12 of a plurality of grating structures on the bonnet; The cooling fan 14 that is provided with in the inboard of air vent hole etc.The cooling system operation principle of this structure is that cooling fan causes enforceable air flows, and the hot-air of PDP inside is arranged to the outside by air vent hole 12 pressures.But in said process,, run into after the shield 13, reflect to PDP through the air that air vent hole is discharged.These return the air of PDP from shield, and the air mixed with discharging from air vent hole 12 forms warm current, impacts the contiguous position of air vent hole 12 simultaneously, sends the noise of impact.
Above-mentioned shield 13 is the parts as the PDP of wall-hanging equipment, is fixed in other position of indoor wall or building.Because PDP is the slim body in large-scale two sides, hangs on metope during use, so above-mentioned noise problem can't be avoided.If not in public places, but when using PDP in general family, all PDP is hung on the wall, noise problem is more inevitable in the family like this, and the influence of noise is more outstanding.
Summary of the invention
The present invention is the noise-proof structure that designs in order to solve the above problems, and can effectively suppress noise among the PDP.Anti-noise structure is provided simultaneously, should reaches cooling purpose, also will resolve the noise reduction problem of the noise that produces by cooling system to solve.
The objective of the invention is to be achieved through the following technical solutions: it comprises the flat-panel screens bonnet, it is characterized in that: the air vent hole of discharging hot-air is set on the flat-panel screens bonnet; In flat-panel screens fuselage inboard, be set up in parallel cooling fan with air vent hole; Having the arranged around periphery of back cover mounting groove of air vent hole; In mounting groove, place sound-absorbing pad.
Good effect of the present invention: the noise that is produced when forcing air draft for effective cooling and plane display, sound-absorbing material is set around airport, make the air that reflects at shield abate the noise, the noise of generation stops its outside propagation when simultaneously also absorbing hot-air and discharging by air vent hole.The user can appreciate program more easily.

Explanation to the main symbol of accompanying drawing:
PDP10,20; Bonnet 11,21; Air vent hole 12,23; Cooling fan 14,26; Shield 13; Mounting groove 22; Sound-absorbing pad 24; Two sides adhesive tape 25.
Embodiment
With reference to the accompanying drawings, a kind of embodiment of the present invention is described:
Referring to Fig. 3, represent following components among the figure: the PDP20 that hot-air takes place; Be positioned at the bonnet 21 at the PDP back side; Be positioned at the top of bonnet, comprise the air vent hole 23 of a plurality of grating structures; Be provided with on the bonnet 21 and form recessed mounting groove 22 by continuous changes shape; Be placed on the interior porousness sound-absorbing pad of mounting groove etc.
Below explain in detail design feature: consider at the inner hot gas that generates of PDP20 to move upward, thereby air vent hole is opened above bonnet 21.
Above-mentioned mounting groove 22 be arranged on air vent hole 23 around.Mounting groove is same shape, and the staggered or continuous arrangement on every side that is located at air vent hole 23 can.In order to make sound-absorbing pad 24 can be placed on 22 li of all mounting grooves, mounting groove 22 is made unified shape, unified size.
Also have, above-mentioned mounting groove 22 is the recessed formation of direction inwards in bonnet 21, and the recessed degree of depth is approximately 5-10mm.It is shaped as the right angle quadrangle, independent formation around air vent hole.Mounting groove 22 is done more greatly under the situation that does not influence PDP20 machine internal work, more deeply for well.
Above-mentioned sound-absorbing pad 24 should be fabricated to goodly with polyurethane or glass fibre, can form numerous apertures but it is inner, uses other material also passable, if be coarse shape with surface treatment, to strengthen sound-absorbing effect with regard to better.Also have, the inner face of the sound-absorbing pad 24 of contact mounting groove 22 inwalls should be a two-sided tape 25, sound-absorbing pad 24 is sticked to install in poor 22.
Use the reason of above-mentioned two-sided tape to be, if PDP hangs over when using on the wall, the noise that reflects from shield is seldom, so there is no need to use sound-absorbing pad 22, at this moment can at an easy rate sound-absorbing pad be removed.
Also have, above-mentioned sound-absorbing pad 24 is made the color identical with bonnet 21 when concrete the use, can make outward appearance more attractive in appearance.
Referring to Fig. 4, fall in and the degree of depth of the installation that forms poor 22 is 5-10mm from bonnet, the thickness of sound-absorbing pad 24 accurately equals to install the poor degree of depth or the poor degree of depth of a little higher than installation, helps effectively absorbing the formed noise of air that baffle such as wall reflects like this.
Referring to Fig. 5, comprise among the figure: the PDP20 that produces hot gas; Be positioned at the bonnet 21 at the PDP back side; Be positioned at the top of bonnet 21 and the air vent hole 23 of many grating structures is arranged; Around air vent hole 23, the mounting groove 22 of bonnet 21 recessed formation; Put the porousness sound-absorbing pad 24 in the mounting groove into; Shield 13 in the face of air vent hole; Be positioned at the cooling fan 26 of air vent hole 23 inboards etc.
On the other hand, sound-absorbing pad 24 also absorbs the air collision noise that bar structure produced of discharging from air vent hole 23 simultaneously greatly not only effectively by the noise that air produced that reflects from shield, propagates into outside total noise thereby reduce.
Arrow among the figure is represented, the direction of air circulation.As can be seen, the air that reflects from shield moves to the sound-absorbing pad direction.
