摘要： A cooling apparatus with a mesh structure for cooling a lampwick of a projector. The cooling apparatus includes a blower, an adjustable air duct disposed at an outlet of the blower. The adjustable air duct further includes an air duct portion, a guiding portion, and a mesh structure. The blower blows cooling air to the air duct that is directly formed on the blower or installed on the blower with a separate air duct. The guiding portion is configured at an outlet of the air duct. The mesh structure couples to the guiding portion to move a lower portion of the guiding portion by gravity so that most part of the cooling air is blown to the lampwick through an upper portion of the guiding portion.

摘要： A cooling device for projector, comprising a light source, an exhaust fan, an air directing fan, an air duct, air inlet windows, an optical engine, a circuit board, a light cut, and a power supply to constitute a projector device with high brightness and high contrast. The projector includes a design that directs hot air flow directly into fan blades of an exhaust fan, thereby effectively reducing adverse effects and solving problems of conventional technology, such as failure to direct hot air flow into the fan blades of the exhaust fan, resulting in excessively high average temperature in the fan hub area that is in alignment with the hot air current, and high working temperature of motor bearings, control circuits, rotors and stators in the fan hub, so that the fan hub can be operating under lower temperatures, thereby enhancing normal performance, effective working life and reliability of the fan and the projector.
