Patent ID: 8511832

Claim:
A projection type image display apparatus for modulating light emitted from a light source lamp based on an image signal to project the modulated image light in an expanded manner, comprising: a first exhaust fan for mainly discharging exhaust air from the light source lamp to exterior; and a second exhaust fan for mainly discharging exhaust air from parts other than the light source lamp; a fan motor for said first exhaust fan, positioned in a center of said first exhaust fan in an axial direction; and a frame body arranging the first exhaust fan and the second exhaust fan adjacent to each other, positioning the second exhaust fan parallel with an exterior air blow outlet and an exhaust end of the second exhaust fan pointing directly away from the projection type image display apparatus, and positioning the first exhaust fan at an angle relative to the second exhaust fan, with an exhaust end of the first exhaust fan being angled toward the second exhaust fan and air sucked by the first exhaust fan being directed towards the exterior air blow outlet, wherein the projection type image display apparatus includes a cooling fan that blows air to an interior air blow outlet communicating with the interior of the light source lamp and the exterior air blow outlet communicating with an outer surface to cool the light source lamp, wherein the cooling fan is used to allow the exhaust air used for cooling the light source lamp to be discharged through the first exhaust fan, and wherein a center of the first exhaust fan on the back side is covered with a cover by which the entire fan motor is blocked, and wherein the center of the cover does not have any holes and is disposed at a position separate from the first exhaust fan.
