Abstract

The invention discloses a projector including a casing, an optical module, a light source module, a blowing fan, and an axial fan. The casing has a first air-outlet, a second air-outlet, and an air-inlet. The blowing fan and the axial fan are disposed corresponding to two sides of a light axis of the light source module respectively. When the blowing fan operates, an initial airflow into the casing from the air-inlet flows through the optical module and then a predetermined airflow generated by the blowing fan on a first air-outlet surface of the blowing fan cools the light source module. An angle is formed between the axial fan and one side of the casing. The axial fan directly sends the air around the light source module out of the casing through the first air-outlet and/or the second air-outlet.
