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, a cooler configured to cool the cooling target based on transformation of a refrigerant into a gas, and a dust-proof case configured to house at least a part of the cooling target inside. The cooler includes a refrigerant generator configured to generate the refrigerant, and a refrigerant sender configured to transmit the generated refrigerant toward the cooling target. The cooling target includes a cooling target main body part, and a cooling target part which is thermally coupled to the cooling target main body part, and to which the refrigerant is transmitted from the refrigerant sender. The cooling target main body part is disposed inside the dust-proof case. The cooling target part is disposed outside the dust-proof case.
