Abstract
An image projection apparatus includes a light source; an intake port to take in low-temperature air into the image projection apparatus; an exhaust port to exhaust air from the image projection apparatus; a first ventilation unit to generate an air flow from the intake port to the exhaust port; a first flow path for hot-air exhaust; a second flow path for a part of the low-temperature air, taken from the intake port; and a mixing unit to mix the hot-air exhaust flowing from the first flow path and the low-temperature air flowing from the second flow path; and a second ventilation unit to generate an air flow for the second flow path to the mixing unit. The air exhausted from the mixing unit converges with another part of the low-temperature air, flowing from a third flow path outside the mixing unit.
