Description
[technical field]
The utility model relates to a kind of plasma display panel, relates in particular to a kind of plasma display panel with heat abstractor.
[background technology]
Plasma display panel is that inert gas or mercury gas are injected the discharge groove that makes with glass tube with vacuum, makes gas produce electricity slurry effect with high voltage again, emits ultraviolet light and bombards phosphor body and send visible light.Visible light colors is by the kind decision of phosphor body, and the image of plasma display panel then is arranged in a combination by the sub-box of many similar sight lamps.
In the application of large-sized monitor, with respect to LCD (LCD) and CRT (cathode-ray tube display), plasma display panel have thin thickness, in light weight, visual angle wide, can do characteristic and advantages such as large scale and high definition digital demonstration, but because inert gas needs could produce gas discharge under action of high voltage, and also need between electrode, load and keep voltage for keeping gas discharge, therefore the discharge groove of plasma display panel will produce high heat, and heat dissipation problem becomes a big technical barrier of plasma display panel.
For traditional plasma display panel, the heat that discharge groove produced will conduct to glass substrate, but because the characteristic of glass substrate, heat is difficult in the direction conduction that is parallel to base plan.Because discharge groove exists part to be driven, and the not driven situation of part, thereby produce driven discharge groove temperature and obviously rise, and not driven discharge groove is temperature-resistant, cause the subregion temperature of glass substrate to raise, and the subregion is constant, produces temperature contrast.And higher temperature contrast will cause glass substrate internal intensity skewness, make glass substrate be easy to fracture, thereby for plasma display panel, it is very necessary to have a good heat abstractor.
United States Patent (USP) the 5th as bulletin on November 23rd, 1999,990, the plasma display panel (as shown in Figure 1) that is disclosed for No. 618, for improving the radiating effect of plasma display panel 150, it provides a heat abstractor 2, this heat abstractor 2 is made by aluminium or its alloy, and links to each other with panel 12 by an adhesive layer 50.Wherein, this adhesive layer 50 is an elastic gel, though it has bonding effect, it does not have good heat-conductive characteristic, the heat that plasma display panel 150 is produced can not be conducted to heat abstractor 2 fast.And this adhesive layer 50 can not realize that heat abstractor 2 contacts with the good of panel 12, because heat abstractor 2 is not definitely smooth with the contact interface of panel 12, if neither one excellent contact interface, generally be in contact with one another area less than 2%, this will influence panel 12 and carry out heat conduction to heat abstractor 2, increase the interface exposure level and will just seem very necessary thereby increase the higher thermal interfacial material of a conductive coefficient between the contact interface of heat abstractor 2 and panel 12.
Because heat abstractor 2 is to be made by aluminium or its alloy, this kind material has isotropic heat dispersion, thereby for fin 212 parts of heat abstractor 2 it has good heat radiation function, can be fast with the heat spread in all directions, but conduct to each side owing to its heat for its substrate 211 parts, thereby heat can not be fast and all conduct to fin 212, and the heat radiation function of fin 212 is difficult to give full play to.
Therefore for plasma display panel, provide a kind of good heat dissipation technology very necessary.
[utility model content]
For overcoming the defective that the prior art plasma display panel can not good heat radiating, the utility model provides a kind of plasma display panel with excellent heat dispersion performance.
The technical scheme of the utility model technical solution problem is: a kind of plasma display panel is provided, and it comprises a display floater; One heat abstractor is bonded on the metacoxal plate of display floater, is used for the heat radiation of display floater; One hot boundary layer between this display floater and this heat abstractor, is used for display floater and contacts and heat conduction with the good of heat abstractor; Wherein, this heat abstractor comprises a substrate and a plurality of fin, and this substrate is the one-way heat conduction substrate, is made by the one-way heat conduction material, be used to conduct heat from display floater to a plurality of fin, and the one-way heat conduction direction of this thermal-conductivity substrate is consistent with the fin bearing of trend.
Compared with prior art, the utility model plasma display panel improves the hot transfer efficiency of plasma display panel by a heat abstractor with one-way heat conduction direction thermal-conductivity substrate consistent with the fin bearing of trend, thereby has excellent heat dispersion performance, and shortens cooling time.
[description of drawings]

Fig. 2 is the generalized section of the utility model plasma display panel.
[embodiment]
Please refer to Fig. 2, the utility model plasma display panel 10 comprises a display floater 100, one a hot boundary layer 200 and a heat abstractor 300, and wherein, this hot boundary layer 200 is arranged between this display floater 100 and this heat abstractor 300.
This display floater 100 comprises a prebasal plate 101, a plurality of discharge groove 103 and a metacoxal plate 105, and wherein these a plurality of discharge grooves 103 are to be parallel to each other into arranged, are sandwiched between this prebasal plate 101 and the metacoxal plate 105.
This hot boundary layer 200 is to be made by a kind of composite material with carbon nano pipe array, comprises a first surface 201 and a second surface 202, and this first surface 201 is relative with second surface 202.Wherein the thickness of this hot boundary layer 200 only is micron order, and its first surface 201 contacts with the metacoxal plate 105 of display floater 100, and its second surface 202 contacts with heat abstractor 300.
This has the composite material of carbon nano pipe array because carbon nano pipe array has even, super suitable, the advantage that aligns, each carbon nano-tube all forms passage of heat in vertical thermal boundary layer 200 directions, make vertical thermal conduction characteristic of carbon nano-tube be utilized, thereby the conductive coefficient height and the heat conduction of this hot boundary layer 200 are even.
