Patent attributes
A projector includes a cooler that cools a cooling target based on transformation of a refrigerant into a gas. The cooler includes a refrigerant generator that generates the refrigerant, a refrigerant sender that sends the refrigerant generated in the refrigerant generator toward the cooling target, and a refrigerant holder connected to the cooling target, the refrigerant holder holding the refrigerant sent by the refrigerant sender and receiving heat from the cooling target to transform the refrigerant into a gas. The refrigerant generator includes a heat exchanger that stores the generated refrigerant therein. In a case where the projector takes a basic attitude, the refrigerant holder and the refrigerant generator are so located in the projector that the surface of the refrigerant stored in the heat exchanger is lower in the gravity direction than the horizontal plane passing through the lowest portion of the refrigerant holder in the gravity direction.
