Abstract
The projector includes a cooler cooling a cooling target based on transformation of a refrigerant into a gas. A refrigerant generator of the cooler includes a moisture absorption/desorption member, a first blower feeding air to the moisture absorption/desorption member, a first heat exchanger, a second blower circulating air inside a circulation channel passing through the first heat exchanger and the moisture absorption/desorption member, a second heat exchanger at least partially disposed in the circulation channel. The second heat exchanger includes a thermoelectric element, a first heat-transfer member coupled to a heat absorption surface of the thermoelectric element, and a second heat-transfer member thermally coupled to a heat dissipation surface of the thermoelectric element. The first heat-transfer member cools the air flowing through the circulation channel. The second heat-transfer member has a heat dissipation section configured to heat the air which was cooled by the first heat-transfer member.
