Abstract
A projector includes a casing, an optical engine module, and a heat dissipation module. The optical engine module is disposed in the casing. The heat dissipation module is disposed in the casing and includes a heat dissipation fin set. The heat dissipation fin set includes at least one heat dissipation fin and at least one turbulent structure. The heat dissipation fin has a surface. The surface includes a first turbulent region and a second turbulent region. The first turbulent region is adjacent to the second turbulent region. The turbulent structure is disposed at least one of the first turbulent region and the second turbulent region, and the turbulent structure protrudes from the surface. An opening is formed between a top end of the turbulent structure and the surface.
