摘要： An image projector (1) that air-cools an image generating device and a light source and can prevent dust from being adhered to optical devices in a projection optical unit is provided. The image projector (1) includes a projection optical unit (30, 40) that projects an image including a gap, and a case (59, 53) that contains the projection optical unit (30, 40). The case (59, 53) includes an exhaust vent (85) that is located on a predetermined surface of the case (59, 53) at a position facing a first fan (86), a first intake duct (92) provided on a surface of the case (59, 53) so as to face a second fan (91), and a second intake duct (84) provided on a surface different than the surface where the first intake duct (92) is provided. Air that flows from the first intake duct (92) toward the exhaust vent (85) is prevented from flowing in the gap, and air that flows from the second intake duct (84) toward the exhaust vent (85) flows in the gap.

摘要： An image projection apparatus (1) includes a light source (61) to emit light for projecting an image to be projected; an intake port (64) to take in low-temperature air into the image projection apparatus; an exhaust port (85) to exhaust air from the image projection apparatus; a ventilation unit (86) to generate an air flow from the intake port (64) to the exhaust port (85); a first flow path for hot-air exhaust having increased its temperature by taking heat from the light source while flowing around the light source; a second flow path for a part of the low-temperature air, taken from the intake port (64), having a temperature lower than the hot-air exhaust; and a mixing unit (98) to mix the hot-air exhaust flowing from the first flow path and the low-temperature air flowing from the second flow path. The air mixed and exhausted from the mixing unit (98) converges with another part of the low-temperature air taken from the intake port (64), flowing from a third flow path set outside the mixing unit (98), at a space between the mixing unit (98) and the exhaust port (85).
