ABSTRACT:
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.
