[description of drawings]
Fig. 1 is the explosive view of a kind of embodiment of all-sealed cooling system DLP projector;
Fig. 2 is the stereographic map of the heat conduction shell of all-sealed cooling system DLP projector.
[embodiment]
Be elaborated below in conjunction with embodiment and accompanying drawing.
All-sealed cooling system DLP projector in this embodiment to shown in Figure 2, comprises shell 10, optical bodies 20, fan and seal like Fig. 1.
Shell 10 is provided with the cavity that holds optical bodies 20, fan and heat conduction shell 40, and shell 10 is provided with air intake opening and exhausr port.
Fan is arranged in this shell 10, comprises supply fan 31 that is arranged on shell 10 air intake openings and the extraction fan 32 that is arranged on shell 10 exhausr ports.
In order to seal the seal of said optical bodies 20, the shape of its shape and optical bodies 20 is suitable, has stopped the optical bodies 20 inner article and the external world and has carried out air exchange, plays dustproof effect.Seal comprises lid 40 and base 60, is tightly connected between lid 40 and the base 60 to surround the space that holds optical bodies 20 optical bodies 20 is sealed in the seal.
As preferred embodiment, seal also comprises with the thermal source of optical bodies 20 is close to setting realizes heat conducting heating radiator to optical bodies 20.Heating radiator is arranged between fan and the optical bodies 20, and the heat of optical bodies 20 is derived and derived outside the shell 10 via the air-flow that fan produces.Heating radiator can be formed directly into (one-body molded with lid 40 or base 60) on lid 40 or the base 60, also can independently be provided with and be close on lid 40 or the base 60.In this embodiment, heating radiator adopts the digital micro-mirror heating radiator 51 of independent conductive digit micro-mirror element (DMD) 24 heats that are provided with and the light source heat radiation device 52 of conduction light source 21 heats.In this embodiment, light source 21 is the primitive colours LED light source.Light source 21 is the main thermal source in the all-sealed cooling system DLP projector; Through on lid 40, offering opening 41, light source heat radiation device 52 is passed opening 41 be close to setting with led light source 21 substrates, supply fan 31 and light source heat radiation device 52 are over against setting; The cold air of suction can directly blow to base 60 outside all-sealed cooling system DLP projector; Cooling radiator is taken away all and is transmitted to the heat on the heating radiator, realizes the efficiently radiates heat to light source 21.Digital micro-mirror heating radiator 51 also can be close to setting with digital micromirror elements 24, and extraction fan 32 and digital micro-mirror heating radiator 51 help the heat radiation of digital micromirror elements 24 over against setting.Heating radiator is close on the base 60, and base 60 is provided with radiating fin 62, can accelerate the heat radiation of seal.The direction that radiating fin 62 is provided with flows to extraction fan 32 for helping air-flow from supply fan 31.
Consider cost, seal can the aluminium material as Heat Conduction Material, lid 40, heating radiator and base 60 can adopt alumina based material.Consider radiating effect, can select for use copper product as Heat Conduction Material.In order to improve radiating efficiency, also radiating fin 62 can be set on the lid 40.
When all-sealed cooling system DLP projector is worked; The thermal source of optical bodies 20 such as light source 21 and digital micromirror elements 24 can produce a large amount of heat; The thermal source of the heating radiator of seal and optical bodies 20 is close to setting; The heat conduction that optical bodies 20 is produced is to seal, and the air-flow that is produced by fan is again derived heat outside the all-sealed cooling system DLP projector.Seal is realized sealing to optical bodies 20 on the one hand, prevents that dust from getting into, and realizes heat conduction on the other hand, to optical bodies 20 radiating and coolings, makes all-sealed cooling system DLP projector steady operation.
The above embodiment has only expressed several kinds of embodiments of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the present invention's design, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with accompanying claims.
