Patent attributes
A projector includes a cooler cooling a cooling target based on transformation of refrigerant into gas. A refrigerant generator of the cooler includes a moisture absorbing and releasing member, a first blower, a heat exchanger, a heater, a second blower, a first circulation duct through which the air sent to the moisture absorbing and releasing member from the heat exchanger passes, and a second circulation duct through which the air sent to the heat exchanger from the moisture absorbing and releasing member passes. The second circulation duct includes a second opening disposed in a position where the second opening and a first opening of the first circulation duct sandwich the moisture absorbing and releasing member in a predetermined direction. An opening area of the second opening is smaller than an opening area of the first opening. When viewed along the predetermined direction, the entire second opening overlaps the first opening.
