The cooling fan 42 drives an airflow, enters the fan module 40 from the air inlet, and blows toward the light source module 50 to control the light source module. Group 50 temperature. Since the light guide tube 20 is generally made by gluing, when the temperature of the light guide tube 20 rises, the glue inside the light guide tube 20 is liable to cause thermal fusion, thereby affecting the performance of the light guide tube 20. Further, the color wheel motor 32 is also a temperature-sensitive component, and when the temperature of the color wheel motor 32 rises, damage is also likely to occur. Further, the light guide tube 20 and the color wheel 31 are also quite sensitive to contamination such as dust. In the prior art, the filter ash 64 is used to isolate the external ash 0535-A21879TWF (N2); A06041; LEMON 5 1322921 dust at the air inlet 61, and the airflow is driven by the system fan 63 to lower the projector. Internal heat_quantity. However, since the air inlet 61 is provided with the filter mesh 64, the gas: flow resistance is increased, so the power of the system fan 63 must be increased. At the same time, since the light guide tube 20 and the color wheel are not aimed at The motor 32 dissipates heat, so that the temperature of the light guide tube 20 and the color wheel motor 32 cannot be effectively controlled. [Invention] The present invention provides a phantom machine, including a wind guide, for solving the problems of the prior art. a cover, a color wheel, a color wheel motor, a light pipe and a first air inlet. The color wheel is disposed in the air hood. The color wheel motor is connected to the color wheel and is located in the air hood. a light pipe is disposed in the air hood, and is corresponding to the color wheel. The first airflow enters the air hood from the first air inlet, passes through the color wheel motor and the light guide tube, and flows out of the air hood By applying the invention, since the first air inlet is opened under the color wheel motor, The first airflow enters, and the first airflow is guided by the air hood and the fan module. Therefore, the first airflow can effectively take away the heat of the color wheel motor, the color wheel® and the light pipe, thereby controlling The color wheel motor, the color wheel, and the temperature of the light guide tube. In addition, the first air inlet is provided with a filter screen, and the air guide cover covers the color wheel motor, the color wheel and the light guide tube It blocks dust pollution. Therefore, the cleanliness requirement in the housing is reduced, and the filter is free from the system air inlet. Therefore, the operating power of the system fan can be reduced, thereby saving energy consumption. [Embodiment] 0535-A21879TWF (N2) A06041; LEMON 6 1322921 ·'.
