  • Publication number: 20240142865
    Abstract: A projection device includes a casing, a projection lens, a light valve module, a light source module, a first heat dissipation module, a second heat dissipation module, a fan, and a guiding member. The first heat dissipation module is disposed corresponding to a first air inlet of a first side cover and connected to the light valve module, and the second heat dissipation module is disposed corresponding to a second air inlet of a second side cover and connected to the light source module. An airflow in an accommodating space of the casing is guided to the guiding member by the fan, and is transferred from the guiding member to an air outlet to flow out of the casing. A direction of an image beam of the projection lens is different from an airflow direction flowing out from the air outlet of a third side cover.
