Optical machine and projector

The embodiment of the utility model provides an optical machine and a projector, and the optical machine comprises a light source generator which is used for transmitting a light beam; the heat pipe radiator comprises a first heat exchange end and a second heat exchange end, a phase change medium capable of circularly flowing between the first heat exchange end and the second heat exchange end is arranged in the heat pipe radiator, and the first heat exchange end of the heat pipe radiator is connected with the light source generator; and the first cooling fan is arranged on at least one side of the heat pipe radiator. In the embodiment of the invention, heat generated by the light source generator is transferred to one side far away from the light source generator by arranging the heat pipe radiator, so that the temperature of the light source generator is effectively reduced. By arranging the first cooling fan on at least one side of the heat pipe radiator, the heat dissipation effect is enhanced, so that th
