Description of the new type: [Technical field to which the new type belongs] This creative system is a kind of lamp cooling device, especially a kind of axial flow fan installed on the projector to install a tapered air duct to the lamp and optical components. The cooling lamp of the projector for cooling. [Previous technology] Due to the rapid development of science and technology, the use of projectors has become more widespread to facilitate human life. The number of attendees will increase or the audience will have a more comfortable visual sincerity. Choose to use it, so you can't afford to be overwhelmed, but it also makes how to improve the projector's better heat dissipation effect, which has become an industry's effort to overcome research and development problems. For conventional technology projectors, in order to cool the high temperature of high-power light bulbs, a single-high-speed exhaust fan is installed to provide high-power lamp exhaust heat from the projector. However, this will cause the overall noise level of the projector to increase, making the manufacturer uncomfortable to sew, and the high-speed vibration will also make the life of the projector. Another one—Wei Fan could not solve the cooling problem of other locations. Therefore, the "projector device" of U.S. Pat. No. 62030159 discloses that because a side of the lamp is near the rear of the projector, a side-by-side fan is arranged, and the fan and the case of the front case are matched. The lower fan draws hot air away from the projector, and the cooling airflow entering it will cool the entire lamp. However, when part of the cooling airflow enters the front lamp housing, it will follow the shape of the front lamp housing and flow to the rear housing, but cannot enter M278919. The hot lamp core will effectively cool the bulb, which will shorten the life of the fan and bulb. Please refer to Figure 1, which is a lamp cooling device for a conventional projector. The lamp cooling device 1 includes a projector lamp 11, a first exhaust fan 12, a second exhaust fan 13, and a blower 14. The first exhaust fan 12 and the second exhaust fan 13 are arranged on a casing 15 adjacent to a projector. The projector bulb 11 has a lamp core portion 111 and a reflecting cover 112. The lamp core portion 111 is disposed in the reflecting cover 112, and the first exhaust fan 12 and the blower 14 are adjacent to the projector bulb 11. The front end is respectively located on two sides of the projector bulb 11, the second exhaust fan 13 is adjacent to the rear end of the projector bulb 11, and the air outlet of the blower 14 faces the lamp core m. In addition, the lamp cooling device 1 is provided with a first partition 16 and a second partition 17 on two sides of the projector lamp u, respectively. The first partition 16 connects the first exhaust fan 12 and the second row. The air fan 13 is divided, so that the airflow for cooling the projector lamp 11 is divided into two. One is to use the first exhaust fan 12 to attract the cold air sent from the air outlet of the blower 14 and direct it into the reflector 112 to cool the lamp core ^. In addition, the second exhaust fan 13 sucks material toward the rear end of the projector lamp H to cool the outer surface of the reflector 112. However, the above-mentioned projection lamp cooling device 丨 can only cool the projector bulb 11, and it is not possible to dissipate other heat-absorbing optical components outside the projector bulb η, so the temperature of the entire projector system M278919 is also quite high during use. Moreover, because the air blower 14 is used for heat dissipation, a wind-cutting sound is generated, and the overall noise remains high. In order to improve the above-mentioned defects, the author devoted himself to research, combined with the application of science, and after continuous efforts, experiments, and improvements, finally proposed an ingenious design that can effectively improve the lamp cooling device of the missing projector. [New content] The main purpose of this creation is to provide a lamp bulb cooler device for a projector, which can provide a large range of air output to cool high-watt bulbs' to achieve better heat dissipation. The secondary purpose of this creation is to provide a lamp cooling device for a projector, which uses a large range of airflow to dissipate other heat-absorbing optical components to achieve the effect of simplifying the projector device. Another purpose of this creation is to provide a lamp cooling device for a projector, which uses the structure of an axial flow fan instead of a blower, and utilizes the feature that the speed of the axial flow fan is slower than the blower to achieve the effect of simplifying the device of the projector. In order to achieve the purpose described above, the present invention provides a lamp cooling device for a projector, which is mainly composed of a projection unit, an axial fan, and at least one exhaust fan. The projection unit has a light bulb and a light: element group. The axial fan and the exhaust fan are respectively disposed on two sides of the projection portion. The axial flow fan guides part of the airflow through the bulb and guides part of the airflow through the optical element group. Finally, the exhaust fan exhausts the airflow absorbed by the bulb and the optical element group. M278919 With the aforementioned structure, the whole can be greatly improved. In order to more clearly describe this creation = ,,, and rate. Cooling and splitting, 丨 take the light bulb of the projector out of π person 1 ~ the center is set, the following will be explained in detail with the illustration.

The axial flow fan 23 and the exhaust fan µ are provided on two sides of the projection unit 20, respectively. The shadow section 2G includes a light bulb 21 and an optical element group 22. The optical element group 22 is composed of a plurality of optical elements (such as filters, rotating color disks, lenses, etc.) dispersedly arranged. Since the optical element group 22 described herein may be a conventional optical element group, and It is not a technical feature of this creation, so it will not be described in detail below. The light bulb 21 further has a light emitting body 211 and a cover body 212, and the light emitting body 211 is disposed in the cover body 212. The optical element set 22 is disposed outside the cover 212 and corresponds to the bulb 21. Therefore, when the light-emitting body 211 generates light, part of the light is directly projected onto the optical element group 22, and another part of the light is reflected to the optical element group 22 through the inner edge surface of the cover 212, so the optical element The group 22 absorbs a large amount of light energy and heat from the light emitting body 211. However, in this creation, the axial fan 23 and the exhaust fan 24 cooperate to form a plurality of airflows. Part of the airflow passes through the light bulb 21 and M278919, and part of the airflow passes through the optical element group 22, that is, the axial flow fan 23 will cool the airflow. Air is drawn in from the outside and sent into the projection section 20 along the axial direction of the blade rotation. Therefore, it has the characteristics of high air volume and large air outlet area, so the airflow of cold air will be widely distributed in the projection section 20. The exhaust fan 24 discharges the rolling flow of heat absorbed by the bulb 21 and the optical element group 22. In the preferred embodiment of the present invention, in order to facilitate the extraction of the heat of the projection portion 20, the exhaust fan 24 is an axial exhaust fan. Therefore, with the aforementioned structure, the overall heat dissipation efficiency can be greatly improved. In other preferred embodiments of the present invention described below, since most of the components are the same or similar to the foregoing embodiments, the same components will be given the same name and number directly, and similar components will be given the same name. However, another English letter is added after the original number to distinguish it and will not be repeated, and it will be described first. Please refer to FIG. 3, which is a schematic side cross-sectional structure diagram of a second preferred embodiment of a lamp cooling device for a creative projector. In the preferred embodiment of the present invention, wherein the exhaust fan 24 of the lamp bulb cooling device 2 of the projector is two, it is the -exhaust air $ 24a corresponding to the bulb 21 The other system is provided with a second exhaust fan 2 at a position corresponding to the optical element group 22. Therefore, when the exhaust fan 23 draws in the cold cake, it will be sent to the projection section 20 along the axial direction of the leaf divergence, and will be widely distributed in the projection section 20. Finally, the first exhaust fan 24a will pass through the inside of the cover 212 and the heat generated by the light I element group 22, and the second exhaust air ^ M278919 24b will be absorbed by the outer surface of the cover 212. The airflow of heat is discharged, so that the first exhaust fan 24a and the second exhaust fan are operated at the same time, which can not only be effectively used on a large high-power bulb, but also reduce noise and increase the Cooling effect. Please refer to FIG. 4, which is a schematic cross-sectional structural view of a third preferred embodiment of a lamp cooling device for a creative projector. In this preferred embodiment, the lamp cooling device 2 of the projector further includes a tapered air duct 25 provided at the air outlet of the axial fan 23. The tapered air duct 25 has a first tuyere 251 and a second tuyere 2S2 with different cross-sectional areas. The first tuyere 2S1 is adjacent to the axial fan 23, and the second tuyere 252 is adjacent to the bulb 21 and faces into the cover 212. By designing the cross-sectional area of the first-window 251 to be larger than the cross-sectional area of the first-window 252, the axial-flow fan 23 sucks in the outer cold air to accelerate and concentrate through the cover 212 to generate the function of concentrated wind. The heat radiation effect of the bulb 21 is added. The cross-sectional area of the air outlet 231 of the axial flow fan 23 is designed to be larger than the cross-sectional area of the first air outlet 251. Part of the cooling airflow blown by the axial flow fan 23 is except that part of the cooling air is blown concentratedly through the tapered air duct 25 In addition to the cover body and the inner luminous body 211, another part of the cooling airflow does not enter the tapered air duct 25 but directly blows to the optical element group 22 卩 for cooling. In this way, after the original creation and reduction fan 23 is used, it can not only provide the function of "concentrated wind" to cool the light emitting body 211 of the bulb 21, but also provide a "wide range" cooling airflow. The cooling work M278919, which is blown to most of the scattered optical elements included in the photonic element group 22, can indeed greatly improve the heat dissipation effect. The above said 'Excerpt from reading good practice, the scope covered by this creation is not limited to the embodiment shown in this creation, any changes made based on the content of this creation; the effects and characteristics of its creation and the embodiment of this creation = Like 'and can be conceived by those skilled in the art, for example: the axial fan 23 is two or more or the exhaust fan 24 is three or more variants' are all covered by this creation . This creative technology scene > The bulb cooling device of the machine can indeed achieve the effect of cooling the high heat, high M air volume and other silk reading elements, and simplify the projection property. The demands of the industry are bribing high-yield New Zealand competitiveness.
