Electronic device and projectors
An electronic device includes blowers. Blowers cool liquid crystal panels for light modulation mounted on illumination optical system for outputting light to a projection lens, respectively, and are disposed on the opposite side to the side where the projection lens of three liquid crystal panels is disposed and are arranged side by side along a first direction facing two liquid crystal panels of three liquid crystal panels.
1. An electronic device, comprising:
a plurality blowers, each of which has an air inlet for sucking air for blowing cooling air from the outside, wherein
the plurality of blowers cool each of three liquid crystal panels, mounted on an illumination optical system for outputting light to a projection lens for light modulation, and are disposed on a side opposite to a side where the projection lens of the three liquid crystal panels is disposed and are arranged side by side along a first direction facing the two liquid crystal panels of the three liquid crystal panels and are arranged such that a direction of the air inlets are in the first direction, and
a number of the blowers is three or more.
2. The electronic device according to claim 1 , wherein
a height of the air outlet of the plurality of blowers are the same each other.
3. The electronic device according to claim 1 , wherein
among the plurality of blowers, a distance from the air outlet of the blower that for cooling the liquid crystal panel other than the two liquid crystal panels facing each other of the three liquid crystal panels to the liquid crystal panel to be cooled by the blower is shorter than a distance from the air outlet of the other blower to the liquid crystal panel to be cooled respectively.
4. The electronic device according to claim 1 , wherein
a position of the air outlet of the plurality of blowers in a direction perpendicular to the first direction are the same each other.
5. The electronic device according to claim 1 , wherein
each of the plurality of the blowers comprises blower fans.
6. The electronic device according to claim 1 , wherein
the plurality of blowers are disposed at intervals at which a predetermined intake amount can be ensured.
7. A projector, comprising:
an electronic device according to claim 1 ,
the projection lens; and
a light source, wherein
the electronic device receives light from the light source and modulates an incident light.
8. An electronic device, comprising:
a plurality of blowers, each of which has an air inlet for sucking air for blowing cooling air from the outside, wherein
the plurality of blowers cool each of three liquid crystal panels, mounted on an illumination optical system for outputting light to a projection lens for light modulation, and are disposed on the side opposite to the side where the projection lens of the three liquid crystal panels is disposed and are arranged side by side along a first direction facing the two liquid crystal panels of the three liquid crystal panels and are arranged such that the direction of the air inlets are the same as each other with respect to the first direction.
9. The electronic device according to claim 8 , wherein
a height of the air outlet of the plurality of blowers are the same each other.
10. The electronic device according to claim 8 , wherein
among the plurality of blowers, a distance from the air outlet of the blower that for cooling the liquid crystal panel other than the two liquid crystal panels facing each other of the three liquid crystal panels to the liquid crystal panel to be cooled by the blower is shorter than a distance from the air outlet of the other blower to the liquid crystal panel to be cooled respectively.
11. The electronic device according to claim 8 , wherein
a position of the air outlet of the plurality of blowers in a direction perpendicular to the first direction are the same each other.
12. The electronic device according to claim 8 , wherein
each of the plurality of the blowers comprises blower fans.
13. The electronic device according to claim 8 , wherein
the plurality of blowers are disposed at intervals at which a predetermined intake amount can be ensured.
14. The electronic device according to claim 8 , wherein
a number of the blower is three, each of the three blowers cools each of the three liquid crystal panels.
