Projector

A projector comprising:

• a first cooling object and a second cooling object;
• a first circulatory cooling device having a first closed housing and adapted to circulate a first cooling gas in the first closed housing to cool the first cooling object disposed in the first closed housing, the first circulatory cooling device including:
• a first circulation fan adapted to circulate the first cooling gas in the first closed housing, and
• a first cooler adapted to cool the first cooling gas circulated, and
• a second circulatory cooling device having a second closed housing and adapted to circulate a second cooling gas in the second closed housing to cool the second cooling object disposed in the second closed housing, the second circulatory cooling device including:
• a second circulation fan adapted to circulate the second cooling gas in the second closed housing, and
• a second cooler adapted to cool the second cooling gas circulated,
• wherein
• the first cooling object is an image forming section including a light modulation device adapted to modulate light entering the light modulation device to form an image, and
• the second cooling object is a first optical component included in an optical component making a contribution to the formation of the image by the light modulation device.
