Abstract
A projector includes a casing, an optic engine, a light module, a control circuit module, a first fan module, and a second fan module. The optic engine, the light module, the control circuit module, the first fan module, and the second fan module are disposed in the casing. The first fan module is an axial-flow fan module and has an air inlet and an air outlet. The air inlet is close to and toward the control circuit module; the air outlet is close to and toward the light module. The first fan module generates an air flow flowing through the control circuit module, the first fan module, and the light module in order. The second fan module has an air outlet close to the optic engine. Thereby, heat produced by the above-mentioned components of the projector in the casing can be dissipated efficiently.
