Abstract:
A projector includes a cooling apparatus configured to cool a cooling target based on a transformation of a refrigerant into a gas. A refrigerant generator of the cooling apparatus includes a moisture absorbing and desorbing member, a first blower, a heat exchanger, a heater, and a second blower. The heat exchanger includes a housing having an internal space into which the air delivered by the second blower flows, and a heat absorbing portion disposed in the internal space, the heat absorbing portion removing heat from the air in the internal space to generate the refrigerant. The housing includes an inlet port through which the air flows into the internal space and an outlet port through which the air is exhausted from the internal space. An air guide portion configured to guide the air flowing into the internal space is disposed in the internal space.
