Abstract

A projection apparatus includes a housing, a projection module, an electronic assembly and a heat dissipating module. The housing has first to fourth sides. The first and second sides are provided with air outlet and first air inlet respectively. A containing space is defined in the housing and has first and second areas. The heat dissipating module includes first to third heat dissipating members and first to second fans. The first, second, third heat dissipating members are connected to a light source module of the projection module. The first heat dissipating member is close to the air outlet. The second heat dissipating member is in the first area. The third heat dissipating member is in the first area and close to the second air inlet.
