A projection apparatus includes a casing, a projection lens, a first fan, a first light source module, a second light source module, a first heat dissipation module, and a second heat dissipation module. A disposing direction of the projection lens divides an accommodating space of the casing into a first region and a second region. The first fan, the first light source module, the second light source module, the first heat dissipation module, and the second heat dissipation module are located in the first region. The first heat dissipation module includes a first heat dissipation fin set and a first heat pipe. The first heat pipe is connected to the first base of the first light source module and the first heat dissipation fin set. The first heat dissipation fin set is disposed adjacent to a first air inlet, and in an axial direction of the first fan.

Projection apparatus

A projection lens module including a lens assembly, a reflector, a housing, a light shading structure, a fan, and an air guiding element is provided. The reflector is disposed on an optical axis of the lens assembly. The reflector includes a reflective surface and a shady surface. The housing covers the reflector, and includes a first part and a second part. The first part and the reflective surface of the reflector jointly define an enclosed space, and the second part and at least a part of the shady surface of the reflector jointly define an air guiding space. The light shading structure overlaps the air outlet in a direction of the optical axis. The fan is disposed outside the housing. The air guiding element connects the fan and the housing, and guides the wind blown by the fan to the shady surface, and the wind leaves from the air outlet.

Projection lens module

A projection apparatus includes a casing, a projection lens, a first and a second light source modules, a first and a second thermal modules respectively thermally coupled to the first and the second light source modules, and a first and a second fans. The casing includes a bottom cover having a first air inlet corresponding to the projection lens, a front cover, a rear cover having a second air inlet, a first and a second side covers, which define an internal space divided into a first and a second areas. The first air inlet is connected to the internal space. A first air outlet of the first side cover and the second air inlet are connected to the first area. The first and the second light source modules, the first and the second thermal modules, and the first and the second fans are disposed in the first area.

A projection device includes a housing, a projection lens, a first light source module, a second light source module, a first heat dissipation module and a second heat dissipation module. The housing includes a front cover, a rear cover, a first side cover, a second side cover, a first air inlet, a second air inlet and an air outlet. The front cover, the rear cover, the first side cover and the second side cover define an accommodation space. A direction of an optical axis of the projection lens divides the accommodation space into a first area and a second area. The second air inlet is located at the first area, and the air outlet is located at the second area. The first heat dissipation module is connected to the first light source module, and the second heat dissipation module is connected to the second light source module.
