Abstract
A light source heat-dissipating device is disposed in a projection apparatus having a casing with an air inlet. The light source heat-dissipating device has a heat-dissipating fin assembly disposed in the casing and having an air intake side, and first and second heat-dissipating fin assemblies, a first air duct, and a fan adjacent to the first and second heat-dissipating fin assemblies. The second heat-dissipating fin assembly is stacked on the first one. The first heat-dissipating fin assembly is between the second one and the air inlet. The first air duct is adjacently-disposed at the air intake side, has a first entrance end connected with the air inlet and a first exit end opposite to the first entrance. The light source heat-dissipating device and projection apparatus improve temperature and life consistency between light source modules. The heat dissipation performances of the first and second heat-dissipating fin assemblies tend to be consistent.
