Abstract:
1. An electronic device, comprising: a casing; a light source mounted in the casing; a discharge duct in the casing and including an air intake port facing the light source and a discharge port to discharge cooling air that is taken from the air intake port and that has cooled the light source; and a discharge fan mounted between the air intake port and the light source in the casing, the discharge port having an opening area smaller than that of the air intake port, a center of the discharge port being eccentric to a center of the air intake port, and a direction of air flow from the discharge fan being inclined with respect to a direction of the discharge of the cooling air from the discharge port, the discharge duct having an eccentric-side wall on the side where the center of the discharge port is eccentric to the center of the air intake port, the eccentric-side wall bulges toward the side where the discharge port is eccentric to the air intake port, and the discharge surface of the discharge fan being inclined away from the eccentric-side wall at a distance from the air intake port toward the discharge port.
