Abstract
One aspect of a projector according to the present disclosure includes an exterior housing, a first fan, and a first circulator. The exterior housing has a first wall portion, a second wall portion located in a direction opposite to a first direction with respect to the first wall portion, and a third wall portion facing a second direction. The second wall portion has an introduction port, and the third wall portion has a discharge port. The first circulator connects the introduction port and a first suction port of the first fan to each other. A cooling target is located in the first circulator in a direction intersecting with a direction in which air flows from the introduction port to the first suction port.
Claims19
A projector including a first cooling target, comprising:
- a light source that emits light;
- an optical modulator that modulates the light emitted from the light source in accordance with an image signal;
- at least one projection optical lens that projects the light modulated by the optical modulator;
- an exterior housing that has a first wall portion, a second wall portion facing the first wall portion, a third wall portion orthogonal to the first wall portion and the second wall portion, a fourth wall portion facing the third wall portion, a fifth wall portion orthogonal to the first wall portion, the second wall portion, the third wall portion and the fourth wall portion, and a sixth wall portion facing the fifth wall portion, and that forms an exterior of the projector;
- a first fan that has a first suction port for suctioning air and a first ejection port for ejecting the air suctioned from the first suction port;
- and
- a third fan that has a third suction port for suctioning the air and a third ejection port for ejecting the air suctioned from the third suction port, wherein
- the second wall portion has a leg and an introduction port that introduces the air present outside the exterior housing into the exterior housing,
- the third wall portion has a discharge port that discharges the air present inside the exterior housing to an outside of the exterior housing,
- a first circulator that connects the introduction port of the second wall portion and the first suction port of the first fan to each other,
- the first fan suctions the air into the first suction port through the first circulator from the introduction port of the second wall, and a portion of the first fan overlaps the introduction port and the first circulator viewing a direction facing the first wall portion and the second wall portion to each other,
- the first cooling target is located at the sixth wall portion side with respect to the first fan,
- the first cooling target is fed the air ejected from the first ejection port, and
- the third fan suctions the air into the third suction port from the introduction port of the second wall and feeds to the optical modulator the air ejected from the third ejection port.
