Abstract
A projector having a cooling target includes a light source configured to emit light, a light modulator configured to modulate the light emitted from the light source, a projection optical device configured to project the light modulated by the light modulator, and a cooloer configured to cool the cooling target based on transformation of a refrigerant into a gas. The cooloer includes a refrigerant generator configured to generate the refrigerant from air, a refrigerant sender configured to transmit the refrigerant generated toward the cooling target, and a first duct configured to guide air including the refrigerant changed to a gas in the cooling target toward the refrigerant generator.
