ABSTRACT:
A projector includes a light source unit, a light source side optical system, a display device for producing a projected image to be projected, a projection side optical system for projecting the projected image produced by the display device, a blower acting as a cooling fan for cooling the light source unit, an exhaust air temperature reducing unit for reducing the temperature of highly heated air which results from the cooling of the light source unit by the cooling fan, and exhaust vents for expelling exhaust air from the exhaust air temperature reducing unit to the outside. The exhaust air temperature reducing unit is made up of a heat pipe and fins.
