Abstract
A projecting device includes a casing, an optical engine, and a heat-dissipating mechanism. The casing includes a lower casing body and an upper casing body covering the lower casing body. The optical engine is disposed in the casing, and includes a light source module. The heat-dissipating mechanism includes a first blower disposed uprightly in the casing and adjacent to one side of the light source module for driving airflow to cool the light source module and the casing. The first blower has a thickness greater than one half of a length thereof and greater than one half of a width thereof. With the arrangement of the first blower, a sufficient amount of airflow is provided to the system to improve the heat-dissipating effect and to enhance system reliability.
