摘要： A projector apparatus equipped with a metal plate structure serving as a light shield against a light source and as a heat radiator is provided. The metal plate structure is arranged over the light source to hide the light source. The metal plate structure extends farther to a cooling fan and connects to the upper end of the air expiration face of the fan. The metal plate structure thus serves as the top plate of the baffle section of the exhaust duct of the fan for leading the air expired from the fan. The metal plate structure also serves as a shield plate, which can be connected to a grounded metal piece.

Further, a second fan, adapted to inspire air from within the projector apparatus, is provided in the central area of the projector apparatus. On the air expiration side of the second fan is a cooling duct for cooling the light source and optical system. In addition, a third fan for cooling a G-LCP unit and an R-LCP unit of the image synthesizing device and a fourth fan for cooling a B-LCP and an R-LCP unit of the image synthesizing device are provided in such a way that the streams of air expired from said third and fourth fans intersect each other. The invention allows operation of a projector apparatus with a fewer fans, yet achieves suppression of exhaust air temperature and noise, and cost reduction as well.

摘要： A first exhaust fan 17 for mainly discharging exhaust air from a light source lamp 19 to exterior and a second exhaust fan 18 for mainly discharging exhaust air from parts other than the light source lamp 19 are arranged to be parallel to each other. An end of the exhaust fan 17 facing the other exhaust fan 18 is moved to the inner side and the one exhaust fan 17 is inclined to discharge air in an exhaust direction toward a direction along which air is discharged from the other exhaust fan 18. There is provided a cooling fan 16 that blows air to an interior air blow outlet 161 communicating with the interior of the light source lamp 19 and exterior air blow outlets 162 and 163 communicating with an outer surface to cool the light source lamp 19. The exterior air blow outlets 162 and 163 are deviated from the center of the outer surface of the light source lamp 19. The cooling fan 16 is used to allow the exhaust air used for cooling the light source lamp 19 to be discharged through the first exhaust fan 17. The first exhaust fan 17 is inclined so that exhaust air is sucked by the first exhaust fan 17 in a direction to the exterior air blow outlets 162 and 163. As a result, a projection type image display apparatus can be minimized while achieving the cooling of the light source lamp, the reduction of the exhaust air temperature, and the reduction of noise of the exhaust fan.
