Beschreibung
Zusammenfassung:	A projector includes a light modulation device; a projection lens; a hermetic housing; a projector housing containing the hermetic housing; a heat exchanger; an air guide wall being located in the hermetic housing and partitioning the air guide passage from a main space containing the light modulation device, the air guide wall including: a communication part adjoining the heat exchanger and providing communication between the air guide passage and the main space, and an opening functioning as an inlet for guiding air from the main space into the air guide passage after the air has passed through the heat exchanger; and a fan located at the inlet so as to introduce the air in the main space into the air guide passage, to guide the air in the air guide passage to the communication part, and to blow the air from the communication part to the heat exchanger.
