ABSTRACT:
The image projection apparatus includes a heat generating member disposed inside the apparatus, an exhaust fan exhausting an air that has cooled the heat generating member to the outside of the apparatus, and a duct guiding the air from the heat generating member to the exhaust fan. An outflow opening of the duct is oriented in a direction different from an inflow direction of the air into an inflow opening thereof. At least one air guiding wall is provided inside the duct, which forms plural airflow paths within a cross section extending along the inflow direction and an outflow direction of the air. The apparatus is capable of reducing unevenness in flow rate of the air when guiding the air toward the exhaust fan using a bent-type duct.
