Abstract
An air-cooling apparatus for a projection television is disclosed. The projection television includes a front casing forming an external appearance of a body of the projection television and having a screen installed therein. A rear casing is coupled to the front casing and has a reflection mirror installed therein. A base is integrally formed at a lower portion of the front casing and has an opening and defines a space below the opening. A blowing duct is installed above the opening in the base, and an image projector is installed above the blowing duct and has heat emitting elements including a beam source, dichroic mirrors, a liquid crystal panel and a projection lens therein. A distributing member is disposed within the space and cooperates with the blowing duct so as to distribute air blown by the blowing duct to the heat emitting elements. Thus, according to the present invention, the heat emitting elements disposed in the image projector of the projection television can be concentratedly air-cooled so that the heat emitting elements are prevented from being over-heated. Also, the internal structure of the projection television can be simplified.
