Embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Embodiment one:
As shown in Figure 1, in back projection casing 1 inner both sides air intake passage 7 and air-out passage 2 are set, air intake passage 7 is provided with air inlet 6 near back projection box house one side, and air-out passage 2 is provided with air outlet 3 near box house one side, and air outlet 3 positions are higher than air inlet 6.Air outlet 3 places are provided with air-out fan 4, quicken flowing of air.Also can fan be set, make air outlet aim at the cooling air outlet of the projector in the back projection casing, also can reach the effect of the hot blast in the casing being discharged casing.
After multilayer back projection display wall forms, wherein the air intake passage of the back projection casing of lower floor is communicated with the air-out passage with the air intake passage of the back projection casing on upper strata separately with the air-out passage, as shown in Figure 2, for the air intake that makes air intake passage and the air-out of air-out passage do not influence each other, can seal the upper end of air intake passage of the superiors and the bottom of undermost air-out passage.The upper opening that can also be formed by air intake passage on the back projection casing of the superiors is installed the air-out fan.The lower openings that is formed by the air-out passage on undermost back projection casing is installed the air intake fan.
During work, cold wind enters air inlet 6 through air intake passage 7, enter in the space at electronics, optical device 5 places of back projection casing, it is cooled off take away the heat that it distributes, and become hot blast, enter air-out passage 2 through air outlet 3 then, for quickening the discharge of hot blast, air outlet 3 places are provided with air-out fan 4.Air inlet advanced also the cold wind of upper strata back projection casing for entering through wind inlet channel, consistent with lower floor back projection casing, thus have better radiating effect, as shown in Figure 3, wherein the direction of arrow is represented the flow direction of wind.No matter how many layers are the back projection display wall have, and the radiating effect of the back projection casing on its upper strata is consistent with the radiating effect of the back projection casing of lower floor, and it is too high that electronics, optical device can temperature rises, thereby can not have influence on the reliability of its serviceable life and system.Wind inlet channel and air-out air channel are arranged in the back projection casing simultaneously, need not reserve heat-dissipating space at the display wall back side, make the back projection unit compactness, can more be applicable to the occasion of limited space system.
Embodiment two:
See also Fig. 4 and Fig. 5, in the present embodiment, air intake passage is arranged on the downside of back projection casing, and the air-out passage is arranged on the upside of back projection casing, and air intake passage and described air-out passage form opening respectively in the back projection casing left and right sides.After multilayer back projection display wall formed, the left side opening of the right openings of the back projection casing of left and right-hand back projection casing was tightly connected in every layer, and forms passage.
The air intake opening of air intake passage and the opening of air-out passage are positioned at the not homonymy of back projection display wall, for the air intake that makes air intake passage and the air-out of air-out passage do not influence each other, can seal the opening of air intake passage of the air-out lower opening portion of the opening of air-out passage of air intake upper opening portion of air intake passage and air-out passage.Also can the air intake fan be set, or/and the air-out fan is set at the opening of the air intake passage of the air-out lower opening portion of air-out passage at the opening of the air-out passage of the air intake upper opening portion of air intake passage.The back projection display unit of each layer has its independent air intake passage and air-out passage like this, and the heat radiation air-out of each layer can not impact the heat radiation air-out of the back projection display unit on upper strata.
More than be preferred embodiment of the present utility model, all employings are equal to replaces or technical scheme that equivalent transformation forms all drops in the protection domain that the utility model requires.
