Abstract
A projector including a cooling target includes a light source, a light modulator, a projection optical apparatus, and a cooler configured to cool the cooling target based on transformation of a refrigerant into a gas. The cooler includes a refrigerant generator configured to generate the refrigerant, a refrigerant sender configured to send the generated refrigerant toward the cooling target, and a cooling air blower configured to deliver air to the cooling target. The cooling target includes a cooling target main body and a cooled part which is thermally coupled to the cooling target main body and to which the refrigerant is sent from the refrigerant sender. The cooled part is disposed on a downstream of the cooling target main body in the flowing direction of the air delivered from the cooling air blower to the cooling target.
