Abstract:
A projection device is disclosed. The projection device includes an air inlet, an air outlet, an optical engine, a heat sink, a fan and a combiner. A first passage is arranged between the air inlet and the air outlet for passing an air flow. The optical engine includes a light source and an imaging lens set outputting a projection light beam. The heat sink is connected to the optical engine, and a part of the heat sink is arranged in the first passage. The fan is arranged in the first passage. The combiner receives the projection light beam. The projection light beam moves in a propagating direction opposite to the entry direction.

Claim (Index 15):
The projection device according to  claim 3 , further comprising:\n a casing comprising a lateral side, the air inlet and a light exit are formed on the lateral side of the casing, the air outlet are formed on another lateral side of the casing, wherein, the projection light beam outputted by the imaging lens set propagates in a light emerging direction via the light exit, the second lens has a concave surface facing the combiner, the air inlet is aligned with the air outlet, and the heat sink comprises at least two heat dissipation fins, a second passage is formed between the heat dissipation fins, the second passage extends in a direction substantially the same as a direction in which the first passage extends, the lateral side on which the air inlet and a light exit are formed is opposite to the lateral side on which the air outlet is formed, the fan is disposed in an inner side of the air outlet or the fan is mounted out of the casing and located in a line connecting the air inlet and the air outlet or the fan is mounted within the casing and located between the air inlet and the air outlet, the combiner has refractive power, the fan is an axial flow fan, the air inlet port is aligned with the air outlet port and the air inlet and the air outlet are substantially at the same height; that a second passage arranged between the heat dissipation fins extends in a direction parallel to the first passage, the lateral side having the air inlet and a light exit is opposite to the another lateral side having the air outlet, the fan is disposed in an inner side of the air outlet or the fan is mounted out of the casing that the fan is located in a line connecting the air inlet and the air outlet or the fan is mounted within the casing that the fan is located between the air inlet and the air outlet, the combiner has refractive power, the fan is an axial flow fan, and the air inlet port is aligned with the air outlet port that the air inlet and the air outlet are substantially at the same height.
