Abstract

A projector with single fan including a casing, a heat source, a light source module and an axial-flow fan are provided. The casing has an air outlet and a first air inlet. The heat source, the light source module and the axial-flow fan are disposed in the casing. The light source module includes a lamp shade and a light-emitting part. The axial-flow fan is disposed in a light outgoing side of the light source module and has an airflow inlet and an airflow outlet. When the axial-flow fan is operating, a first airflow is generated. After flowing through the heat source, the first airflow enters the airflow inlet and generates a second airflow. The second airflow, blown out from the airflow outlet, dissipates the heat generated by the light source module and then flows out to the outside of the casing.
