A projector includes: a light source unit configured to emit light; a light source heat absorber configured to cause coolant to absorb heat from the light source unit; an ejector pump configured to allow passage of the coolant having absorbed the heat in the light source heat absorber; a radiator configured to radiate the heat of the coolant flowed out from the ejector pump; an evaporator configured to cool the coolant stored in the evaporator by evaporating the coolant; and a heat source other than the light source unit, wherein the ejector pump decompress the interior of the evaporator by a pressure drop due to the passage of the coolant having absorbed the heat in the light source heat absorber, and heat from the heat sources other than the light source unit is absorbed by the coolant cooled by the evaporator. |
