A projector comprises a case, an illuminant heat source, a thermal module, and an equalizing temperature module. The equalizing temperature module is disposed between the illuminant heat source and the thermal module. When the fluid flows from the illuminant heat source to the equalizing temperature module, the fluid flows through a relative high temperature region more than that of flowing through a relative low temperature region. The equalizing temperature module at least comprises a heat pipe and a plurality of heat sinks. The heat pipe has a first end located in the relative low temperature region and a second end located in the relative high temperature region. The heat pipe transfers heat from the relative high temperature region to the relative low temperature region by a cold fluid in the heat pipe. The plurality of heat sinks are disposed on the heat pipe to increase the area of heat conduction. The projector can uniform the fluid temperature by means of the equalizing temperature module so as to increase life time and reliability of the thermal module.
