Abstract
A projector includes a first circulation channel formed in a sealed space and where a first fluid for cooling a cooling target arranged within the sealed space circulates, a second circulation channel where a second fluid to which heat is conducted from the first fluid circulates, and a third circulation channel where a third fluid to which heat is conducted from the second fluid circulates and where the heat conducted to the third fluid is radiated in a process of circulation of the third fluid. The first fluid is gas. The second fluid and the third fluid are liquid.
Claims11
A projector comprising:
- an exterior casing that forms an exterior of the projector;
- a sealed casing that is disposed in the exterior casing, and has a sealed space;
- a circulating cooling device that is configured to form a first circulation channel (i) formed in the sealed space and (ii) the first circulation channel circulates a first fluid for cooling a cooling target arranged within the sealed space;
- a heat absorption device that has a heat absorber to absorb heat from the first fluid in the first circulation channel, and that is configured to form a second circulation channel that circulates a second fluid that absorbs heat from the first fluid;
- a heat radiation device that is configured to form a third circulation channel where a third fluid to which heat is conducted from the second fluid circulates and where the heat conducted to the third fluid is radiated in a process of circulation of the third fluid;
- and
- a heat exchanger connected to the second circulation channel and the third circulation channel;
- wherein the heat exchanger includes a heat receiving section configured to receive heat from the second fluid, and a heat radiation section configured to radiate the heat conducted from the heat receiving section to the third fluid,
- wherein the first fluid is gas,
- wherein the second fluid and the third fluid are liquid, and
- wherein the first circulation channel, the second circulation channel, and the third circulation channel are disposed within the exterior casing.
