PROJECTOR

摘要

A projector includes a cooling fan that discharges cooling air toward a liquid crystal panel as a target to be cooled, a liquid crystal panel frame that holds the liquid crystal panel, and a turbulence generator that is disposed at an upstream-side end portion of the liquid crystal panel in relation to the cooling air, converts the cooling air into turbulence, and causes the turbulence to flow toward the liquid crystal panel, and the turbulence generator includes an inclined section having an inclined surface and a plate-shaped protruding section formed on the inclined surface and inclined by an inclination angle with respect to a direction in which the cooling air flows into the turbulence generator.

1. A projector in which light outputted from a light source apparatus is optically processed through an optical system having a plurality of optical parts and resultant image light is projected, the projector comprising:
a cooling fan that discharges cooling air toward any of the optical parts as a target to be cooled; a holding member that holds the optical part; and a turbulence generator that is disposed at an upstream-side end portion of the optical part or the holding member in relation to the cooling air, converts the cooling air into turbulence, and causes the turbulence to flow toward the optical part, wherein the turbulence generator includes an inclined section having an inclined surface and a plate-shaped protruding section formed on the inclined surface and inclined by an inclination angle with respect to a direction in which the cooling air flows into the turbulence generator.
