Detailed Description
For a better understanding of the technical solution of the present utility model, the embodiments provided by the present utility model are described in detail below with reference to the accompanying drawings.
Example 1
As shown in fig. 1 to 3, it can be understood that the internal air path system of the projector according to the present embodiment includes: the shell 1 is characterized in that a first fan 2 is arranged in the shell 1, a circuit board 3 is arranged in the direction of an air outlet of the first fan 2, a second fan 4 is arranged beside the circuit board 3, and an air inlet of the second fan 4 is opposite to the circuit board 3; the shell 1 is provided with a vent hole 5, and an air outlet of the second fan 4 is opposite to the vent hole 5.
In this embodiment, the first fan 2 is disposed at a heat generating portion in the housing 1, and blows out the hot air emitted from the heat generating portion, in this embodiment, the air path extends to the circuit board 3, the circuit board 3 generates hot air, the circuit board 3 is further provided with the second fan 4, the air inlet of the second fan 4 is close to the circuit board 3, the hot air carried by the first fan 2 and the hot air generated by the circuit board 3 are absorbed by the air inlet of the second fan 4 and blown out by the air outlet, the air outlet of the second fan 4 is disposed at the air vent 5 of the housing 1, and all the hot air is blown out by the air vent 5 to form an air path system, so that the hot air generated in the housing 1 is guided out of the housing 1, and the hot air generated in the housing 1 is free from being emitted or returned, thereby achieving a better cooling effect.
Further, a first heat sink 6 is disposed between the first fan 2 and the circuit board 3. The first radiator 6 in this embodiment is used for radiating heat from the projector optical machine 9, and hot air radiated from the optical machine 9 is blown to the circuit board 3 by the first fan 2 and finally guided to the vent hole 5.
Further, a first cover plate 7 is disposed outside the first fan 2 and the first heat sink 6, and the first cover plate 7 covers and closes the top of the first fan 2 and the first heat sink 6. In order to ensure the guiding function of the air path system and avoid the divergence of the air path, a first cover plate 7 is arranged outside the first fan 2 and the first radiator 6, the first cover plate 7 encloses the first fan 2 and the first radiator 6, a channel of the air path is reserved, and hot air emitted by the first radiator 6 is prevented from being blown to diverge by the first fan 2, so that the hot air travels along a preset air path, and the radiating effect is achieved.
