PROJECTOR

摘要

A projector includes a cooling device cooling a liquid crystal panel. The cooling device includes a heat receiving part receiving heat of the liquid crystal panel, a Peltier device having a heat absorbing part that absorbs the heat of the heat receiving part and a heat generating part that generates heat when the absorbing part absorbs heat, a heat sink provided so that heat may be transferred to the heat generating part, and a heat pipe containing a hydraulic fluid inside, in which heat is transferred by convection of the hydraulic fluid. The heat sink has a stacking part superimposed on the Peltier device and a projecting part projecting from the Peltier device as seen from the Peltier device side, and the heat pipe has an interior part located between the Peltier device and the stacking part and an extending part extending along the projecting part.
