摘要： Disclosed is a cooling apparatus of a color wheel for color separation in a single plate type projector and a projection system using the projector, which comprises an airflow generator, thereby cooling the color wheel and a rod lens of the single plate type projector. The cooling apparatus of the color wheel of the projector of the present invention prevents the color wheel and the rod lens from being thermally degraded by using the high-powered lamp. Further, an airflow generator such as the airfoil-shaped or plate-shaped blades is formed on a hub of the color wheel, thereby miniaturizing the system of the projector and reducing its production cost.
