Abstract

La présente invention porte sur un dispositif d'évacuation de projecteur dans lequel, même lorsque le dispositif d'évacuation est relié à un conduit qui réalise une aspiration tout le temps, de l'air est uniquement pris depuis un orifice d'admission lorsque le projecteur est en fonctionnement, et il n'y a pas d'incidence de colmatage non nécessaire. La présente invention présente : une partie d'ouverture ; et une plaque tournante configurée de manière à être apte à tourner. La plaque tournante bloque l'orifice d'évacuation par gravité lorsque le ventilateur de refroidissement est dans un état de non-fonctionnement, et est soulevée par la pression d'évacuation générée par le ventilateur de refroidissement et la force d'aspiration provenant du conduit et amenée à bloquer la partie d'ouverture lorsque le ventilateur de refroidissement est dans un état de fonctionnement.
