Abstract
Disclosed are an optical engine module and a projection device. The optical engine module includes a housing, a prism component, a light valve, an air guiding channel, a first fan, and a first heat-dissipating module. The housing has a first opening and a second opening. The prism component is disposed in the housing. The light valve is disposed in the housing. The air guiding channel is disposed outside the housing and communicates with the first opening and the second opening of the housing. The first fan is disposed in the air guiding channel. The first heat-dissipating module includes a first heat-dissipating fin disposed in the air guiding channel, and a second heat-dissipating fin disposed outside the air guiding channel.
Claims18
An optical engine module, comprising:
- a housing, having a first opening and a second opening;
- a prism component, disposed in the housing;
- a light valve, disposed in the housing;
- an air guiding channel, disposed outside the housing and communicating with the first opening and the second opening of the housing, wherein the air guiding channel comprises a main channel, a first extending channel and a second extending channel, the first extending channel and the second extending channel are respectively connected to the main channel, and an extending direction of the main channel is different from an extending direction of the first extending channel and an extending direction of the second extending channel;
- a first fan, disposed in the main channel of the air guiding channel;
- and
- a first heat-dissipating module, comprising a first heat-dissipating fin disposed in the main channel of the air guiding channel, and a second heat-dissipating fin disposed outside the air guiding channel.
An optical engine module, comprising:
- a housing, having a first opening and a second opening;
- a prism component, disposed in the housing;
- a light valve, disposed in the housing;
- an air guiding channel, disposed outside the housing and communicating with the first opening and the second opening of the housing;
- a first fan, disposed in the air guiding channel;
- and
- a first heat-dissipating module, comprising a first heat-dissipating fin disposed in the air guiding channel, and a second heat-dissipating fin disposed outside the air guiding channel, and a heat conduction element thermally coupling, the first heat-dissipating fin and the second heat-dissipating fin.
A projection device, comprising:
- an illumination system, configured to provide an illumination beam;
- an optical engine module, comprising:
- a housing, having a first opening and a second opening;
- a prism component, disposed in the housing and located on a transmission path of the illumination beam;
- a light valve, disposed in the housing and adaptable for converting the illumination beam from the prism component into an image beam;
- an air guiding channel, disposed outside the housing and communicating with the first opening and the second opening of the housing, wherein the air guiding channel comprises a main channel, a first extending channel and a second extending channel, the first extending channel and the second extending channel are respectively connected to the main channel, and an extending direction of the main channel is different from an extending direction of the first extending channel and an extending direction of the second extending channel;
- a first fan, disposed in the main channel of the air guiding channel;
- and
- a first heat-dissipating module, comprising a first heat-dissipating fin disposed in the main channel of the air guiding channel, and a second heat-dissipating fin disposed outside the air guiding channel;
- and
- a projection lens, disposed on a transmission path of the image beam, and configured to project the image beam out of the projection device.
