Abstract
A liquid-cooled projector incorporating cooling a component that to be cooled by a cooling liquid, and moreover, can constantly maintain the temperature of the component to be cooled at a prescribed temperature or below. A liquid-cooling jacket for cooling either one or both of the optical modulation element and cold mirror, which are the components that are to be cooled, one or a plurality of radiators, one or a plurality of reserve tanks, and one or a plurality of circulation pumps are connected together by piping. The components that are to be cooled are maintained at or below the prescribed temperature by circulating the cooling liquid through the system, which can further be separated at any position by couplers. By collecting the air that is generated in the cooling system in the reserve tank, idle running of the circulation pump can be prevented, and the effect of expansion and shrinkage in the volume of the cooling liquid can be mitigated.
