PURPOSE: A system for cooling a liquid projection device is provided to increase the cooling efficiency with a fan of a small capacity by cooling heat of a polarization plate locally, thereby reducing the noise due to the use of a large capacity fan and preventing the degradation of the performance of the system due to the thermal degradation of the polarization plate. CONSTITUTION: A system for cooling a liquid projection device includes a polarization plate(41), a metal plate(43) of high heat conductivity, heat pipes(42) attached to the polarization plate by an adhesive agent such as cementite for conveying heat effectively, and heat emission fins(44) connected to the heat pipes for emitting the conveyed heat, wherein the metal plate is interposed between the heat pipes and the polarization plate for transmitting heat. |
