Projector

A projector including a cooling target, the projector comprising:

• a light source configured to emit light;
• a light modulator configured to modulate, according to an image signal, the light emitted from the light source;
• a projection optical device configured to project the light modulated by the light modulator;
• and
• a cooler configured to cool the cooling target based on transformation of a refrigerant into gas, wherein
• the cooler includes:
• a refrigerant generator configured to generate the refrigerant,
• a refrigerant sender configured to transfer the generated refrigerant toward the cooling target,
• the refrigerant generator includes:
• a rotating moisture absorbing and releasing member;
• a first blower configured to send air to a portion of the moisture absorbing and releasing member located in a first region;
• a heat exchanger connected to the refrigerant sender;
• a heater configured to heat a portion of the moisture absorbing and releasing member located in a second region different from the first region;
• and
• a second blower configured to send, to the heat exchanger, air around the portion heated by the heater in the moisture absorbing and releasing member,
• the heat exchanger includes:
• a housing including an internal space into which the air sent by the second blower flows;
• and
• a plurality of channels disposed in the internal space,
• insides of the plurality of channels are separated from the internal space, and
• cooling air for cooling the air in the internal space via the plurality of channels flow through the insides of the plurality of channels.
