Patent ID: 10705414

Abstract:
A projector a cooler configured to cool a cooling target based on transformation of a refrigerant into a gas. The cooler includes a refrigerant generator configured to generate the refrigerant and a refrigerant sender configured to send the generated refrigerant toward the cooling target. The refrigerant generator includes a moisture absorbing/discharging member, a first air blower configured to deliver air outside the projector to the moisture absorbing/discharging member, a heat exchanger connected to the refrigerant sender, a heater configured to heat the moisture absorbing/discharging member, and a second air blower configured to deliver, to the heat exchanger, air around a portion of the moisture absorbing/discharging member that is the portion heated by the heater. The heat exchanger, by cooling the air having flowed into the heat exchanger, generates the refrigerant from the air having flowed into the heat exchanger. The moisture absorbing/discharging member is fixed.
