Following embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.
Embodiment
Below in conjunction with accompanying drawing, the present invention being done one specifically introduces.
See also shown in Figure 1ly, be the embodiment schematic diagram of projector optical-mechanical heat abstractor of the present invention, described heat abstractor 10 comprises a housing 12, a blower module 14, a bare engine module 16 and a radiating module 18.Described housing 12 is interior arranges described bare engine module 16, and described bare engine module 16 comprises a light source 161, a Multiplexing apparatus 162, a leaded light component 163, a water chestnut mirror group 164, a digital micro-mirror display device 165 and a projection lens group 166.Described light source 161 is mainly in order to produce three primitive color lights, i.e. red light, blue light and green light.Described three primitive color lights assemble by described Multiplexing apparatus 162 and close the light light beam at same optical axis, then the described light light beam that closes of described three color of light is projected to described leaded light component 163, the running that described leaded light component 163 can carry out the described even light that closes the light light beam and eliminate hot spot, and guide the described light light beam that closes and be projected to described water chestnut mirror group 164 and described digital micromirror display device 165.Described water chestnut mirror group 164 is the reverse total internal reflection water chestnut mirrors (RTIR, Reverse Total Internal Reflection) that are combined to form by two water chestnut mirrors.Described water chestnut mirror group 164 first is projected to the described light light beam that closes on described digital micromirror display device 165 (DMD, Digital Micro-mirror Device) with total internal reflection.Described digital micromirror display device 165 is in accepting describedly to consist of an image strip after closing the light light beam, described image strip oppositely refracts to described projection lens group 166 by described water chestnut mirror group 164 again, thereby the described image that described digital micromirror display device 165 consists of can be gone out by projection.The described light source 161 of described bare engine module 16 is that projector's heat energy mainly produces part, therefore, described bare engine module 16 is to be connected with described radiating module 18 at described light source 161 places, and the heat energy that described light source 161 is produced can dispel the heat by described radiating module 18.Described radiating module 18 is connected with the described light source 161 of described bare engine module 16 and is positioned at described housing 12 outsides.Described radiating module 18 is except connecting described light source 161, other electronic package that can produce heat energy of projector also can be arranged on described radiating module 18, described radiating module 18 is generally highly heat-conductive material, the radiating fin (not indicating in figure) that can increase area of dissipation also can be set, make described radiating module 18 form the zone of heat interchange.
Please consult shown in Figure 2ly, described housing 12 has first room 122 and one the 2 124 and arranges, and has a passage 126 that communicates between described first and second room 122,124 again.In present embodiment, described first and second room 122,124 is for parallel being set up in parallel, and described passage 126 is positioned at described first and second room 122, a side of 124.Described housing 12 materials are the metal material with conductive force.Described the first room 122 is in order to arrange described light source 161 (as shown in Figure 1), 124 of described the second rooms arrange described projection lens group 166, and described Multiplexing apparatus 162, described leaded light component 163 and described water chestnut mirror group 164 are the described passages 126 that are positioned at described housing 12 with described digital micromirror display device 165, make that described bare engine module 16 can be complete be arranged at described housing 12 within.The light path of described bare engine module 16 carries out within described housing 12, is externally throwed away by described projection lens group 166 after described light source 161 projections.Described housing 12 has a fan runner 120 and arranges on the outside of described passage 126, described fan runner 120 is the fair water fins for circular arc.The top of described fan runner 120 forms an opening 1202, and forms a breach 1204 at the side of described fan runner 120.Described opening 1202 use arrange described blower module 14 (as shown in Figure 3) so that described fan runner 120 is easy to assembling.Described blower module 14 comprise a driver 142 with and flabellum 144, described driver 142 and described flabellum 144 can be directly be assembled in described fan runner 120 inside by described opening 1202 places of described fan runner 120 tops.Compared to the radiator fan setting of general projector, need to be with the design and assembly of holder collocation guide duct on engine housing, the directly assembling on described fan runner 120 of blower module 14 of the present invention is obviously conveniently to save again many design man-hours.Described blower module 14 is centrifugal fan, described blower module 14 be arranged at described fan runner 120 interior after, described flabellum 144 be axially to be an air intake vent 146, described air intake vent 146 is over against described opening 1202 places of described fan runner 120, and be an air outlet 148 with described flabellum 144 axial vertical place, described air outlet 148 is over against described breach 1204 places of described fan runner 120.Described flabellum 144 makes air enter from axial described air intake vent 146, then sends from the described air outlet 148 of vertical axial via the guiding of described fan runner 120 after driving running by described driver 142.The described breach 1204 of described fan runner 120 makes described air outlet 148 also directly towards described radiating module 18 (as shown in Figure 4) towards described radiating module 18.Therefore, the driving of described blower module 14 running, near the air will making around described housing 12 produces disturbance, thereby air is entered by described air intake vent 146, by the guiding of described fan runner 120, send and produce one air-flow by described air outlet 148.Described air-flow is except blowing by also facing toward described radiating module 18 described housing 12, the effect that can dispel the heat to described housing 12 and described radiating module 18, thereby described bare engine module 16 dispels the heat via described radiating module 18 except described light source 161, described bare engine module 16 carries out cooling simultaneously via described housing 12, when the efficient that can more promote described bare engine module 16 cooling heat dissipations.
The described fan runner 120 that projector optical-mechanical heat abstractor of the present invention, described housing 12 outsides have arranges, can be in order to the described blower module 14 of direct-assembling, and the assembling design that makes described blower module 14 is convenient and make cost for it.The radiating airflow that described blower module 14 of while produces on described housing 12 can improve the heat dissipation to the interior described bare engine module 16 of described housing 12.
In addition, those skilled in the art also can do other variation in spirit of the present invention, and certainly, the variation that these are done according to spirit of the present invention is within all should being included in the present invention's scope required for protection.
