Embodiment
All features disclosed in this specification, or disclosed all methods or during the step of, except mutually exclusive
Feature and/or step beyond, can combine in any way.
Elaborate with reference to Fig. 1 to the utility model.
The utility model is disclosed for the defects of existing projecting apparatus liquid crystal display radiating efficiency is poor, radiator structure is complicated
A kind of projector architecture device that can give liquid crystal display high efficiency and heat radiation, including base 1 and be arranged on above described 1 one end of base
Liquid crystal display 3b, is provided with the second Fresnel Lenses 3c, in the base 1 away from the liquid in the liquid crystal display 3b sides
Crystalline substance screen 3b one end is provided with fan 1a, and it is saturating that the fan 1a sides are provided with the first Fresnel in the liquid crystal display 3b
Air passage 2a is formed between mirror 3a, the fan 1a and the first Fresnel Lenses 3a, the base 1 is close to described
The width of liquid crystal display 3b sides is more than it close to the width of the fan 1a sides, the width of the first Fresnel Lenses 3a
Width of the degree less than the liquid crystal display 3b, the width of the first Fresnel Lenses 3a bottoms are less than below described
The width of base 1 makes the first Fresnel Lenses 3a both sides form the gap for connecting the air passage 2a.The utility model
In, make the air passage that formation width gradually increases above base, width of the air passage close to liquid crystal display side is more than it close to fan
The width of side.
When fan is dried to liquid crystal display direction, low-temperature airflow is flowed along air passage to the first Fresnel Lenses direction, by
Width in air passage gradually increases so that air-flow can be in gradual dispersion flows, make air-flow will not concentration of local in the first Fresnel
Lens side.
Since the width of the first Fresnel Lenses is less than the width of the base of its bottom, in air-flow flow process, Neng Goufen
The scattered gap along the first Fresnel Lenses both sides flow to liquid crystal display side, so that low-temperature airflow can be quickly to liquid
Crystalline substance screen cools down, and realizes the heat dissipation of liquid crystal display.
In the utility model, the air of fan blowout, by air passage, radiates to liquid crystal display;The air passage passes through liquid crystal display
Bottom blows to liquid crystal display, and air passage is realized along the gap at the first Fresnel Lenses both ends and divided close to the position of liquid crystal screen component
Stream, the air-flow of the cooling liquid crystal display a, part can be dispersed into outside projector;A part is circulated in internal body.
The air-flow that fan is produced by boasting, radiates by air passage to liquid crystal display, then circulation in a part, part discharge projection
Outside machine, radiating efficiency is higher;Secondly, the air-flow of fan blowout, by longer liquid crystal display side, radiates to liquid crystal display, air-flow
Speed it is relatively low, so the noise produced is smaller, while if if dust granule in air-flow, will not easily adhere to
On liquid crystal display;Fan used in the utility model, has more flexible placement position, be conducive to complete machine volume-diminished and
Increase space availability ratio.
Embodiment 1:
In order to further improve the radiating efficiency of liquid crystal display, in the present embodiment, it is preferable that the width of the liquid crystal display 3b
Less than the width of the second Fresnel Lenses 3c.In the present embodiment, the width by making the second Fresnel Lenses is more than liquid

Between space in, radiate to the one side of liquid crystal display;Another part air flows to the sky between liquid crystal display and Fresnel lenses 2
Between, radiate to the another side of liquid crystal display;The air passage and the close position of liquid crystal screen component, diversion design have carried out accordingly
Design.It can form that the air-flow of liquid crystal screen component one side is larger, air-flow simultaneously is smaller.
By realizing the shunting of air-flow in liquid crystal display both sides, low-temperature airflow is set to reach the second phenanthrene by liquid crystal display both sides
Between Nie Er lens and liquid crystal display, the synchronous heat exchange of liquid crystal display both sides is realized, can aid in the heat dissipation effect for improving liquid crystal display
Rate.
Embodiment 2:
In the present embodiment, in order to improve the utilization ratio of low-temperature airflow, it is preferable that the axis of the fan 1a is located at
Lower section makes the fan 1a blow to lower section in the middle part of the first Fresnel Lenses 3a in the middle part of the liquid crystal display 3b.By making
Fan blows to lower section in the middle part of the first Fresnel Lenses so that air-flow can realize circulation along base in air passage, in air-flow stream
During dynamic, air-flow can be made to be flowed more easily along the first Fresnel Lenses to its both sides gap, then enable air-flow
Circulation is realized in air passage, while can cause air flow through that the first Fresnel Lenses both sides reach liquid crystal display and the first Fresnel is saturating
Between mirror, low-temperature airflow is set more fully to realize heat exchange with liquid crystal display.
In the present embodiment, fan can be made to be vertical setting, it is preferable that the axis of the fan 1a is parallel to described
The upper surface of base 1 makes the fan 1a parallel with the liquid crystal display 3b.Air-flow is set directly to blow to the first luxuriant and rich with fragrance alunite at this time
Lower section in the middle part of your lens.
In the present embodiment, fan can also be made to tilt installation at an angle with base, it is preferable that the fan 1a's
Axis tilts at an angle with the base 1.
Fan is blowed to lower section in the middle part of the first Fresnel Lenses at this time, allow the flow to quickly through the first Fresnel Lenses
The gap of both sides enters liquid crystal display both sides, effectively improves the utilization ratio of low-temperature airflow.
