Abstract
A cooling system is for cooling a lamp module within a projection apparatus and includes an axial fan unit for mounting within the projection apparatus, defining an axial direction and having an air discharging side to permit an airflow flow therethrough, the airflow defining a flow direction that cooperates with the axial direction to define an angle therebetween. The system further includes a flow-guiding duct that has an air inlet located adjacent to the discharging side of the axial fan unit and that is oriented toward the angle in such a manner to define the flow direction for guiding the airflow toward the lamp module.
