Title:
VIDEO DISPLAY DEVICE AND COOLING DEVICE FOR OPTICAL DEVICE
Document Type and Number:
Japanese Patent JP3724532
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To efficiently cool a part to be cooled, by efficiently using wind from a cooling fan.
SOLUTION: An outside wall 32 and an inner wall part 33 of a wind guide part 30 guide rotating wind generated by a cooling fan to the wind intake ports 31R, 31G, and 31B without losing the wind velocity by rectifying and directing the wind according to the shape and the rotating direction of the cooling fan. The wind passing through the wind guide part 30 is taken in an optical unit 5 from the wind intake ports 31R, 31G, and 31B, and is sent to the parts to be cooled such as liquid crystal light valves and a polarizing plate, etc., for cooling the parts to be cooled.
