Abstract
An image projection apparatus according to the present invention, includes: an air-intake port that takes in outside air for cooling the inside of a housing; a heater that is provided near the air-intake port and generates heat with supply of electric power; a temperature sensor that is provided next to the heater; and a controller that monitors a decrease in the flow velocity of outside air taken in through the air-intake port based on temperature values measured by the temperature sensor.
Claims8
An image projection apparatus comprising:
- an air-intake port that is provided at a housing and is configured to take in outside air for cooling inside of the housing;
- a heat generating unit that is provided near the air-intake port and generates heat with supply of electric power;
- a temperature detecting unit that is provided next to the heat generating unit;
- and
- a controlling unit that monitors a decrease in a flow velocity of outside air taken in through the air-intake port based on a temperature value measured by the temperature detecting unit.
