Abstract
A heat dissipation device of a light engine for a projector has a housing, a fan module, a light engine and a heat sink. The light engine is positioned in the housing and connected to the heat sink. The heat sink is positioned out of the housing. The housing has a fan-enclosed flow channel attached on an outer surface of the housing. The fan module is guided by the fan-enclosed flow channel to the heat sink to enhance heat dissipation efficiency of the light engine for the projector.
