Abstract
A projector includes: an optical component disposed inside a closed structure having air flow path through which air flows; and a circulating fan which circulates air. The closed structure includes: an optical component housing which accommodates the optical component; a duct which introduces air into the optical component housing, and introduces the air having flowed to the outside from the inside of the optical component housing again toward the inside of the optical component housing; and a plurality of heat exchangers each of which has a heat receiving side heat transfer member which faces the inside of the closed structure, and a heat releasing side heat transfer member which faces the outside of the closed structure. The plural heat exchangers are disposed in the air flow direction along the air flow path through which air flows to the outside from the inside of the optical component housing.
