The first air duct 5 is communicated with the air inlet 11 on one side in the width direction of the shell 1, so that the external air can enter the first air duct 5 from the air inlet 11 to cool the first driving plate 21. The first radiator 23 is arranged on the side of the second driving plate 22 close to the first driving plate 21, so as to enhance the cooling capacity of the second driving plate 22. The third air duct 7 is formed between the first driving plate 21 and the second driving plate 22, and the third air duct 7 is communicated with the air inlet 11, so that the external air can enter the third air duct 7 from the air inlet 11 and cool the first driving plate 21 and the second driving plate 22.
[0036] Please refer to Figure 4 and Figure 5 The second heat source 3 comprises a light engine module 31, the fan 4 is arranged in a spaced manner on the bottom of the light engine module 31, the second air duct 6 is formed between the light engine module 31 and the fan 4, and the second air duct 6 is communicated with the air inlet 11, so that the external air can enter the second air duct 6 from the air inlet 11 to cool the light engine module 31. In addition, the fan 4 has a first air suction port and a second air suction port, the first air suction port of the fan 4 is communicated with the second air duct 6, so that the fan 4 can suck the air flow in the second air duct 6, thereby realizing the flow of the air flow in the second air duct 6. The air outlet of the fan 4 is opposite to the air outlet, in this embodiment, the fan 4 has a first air outlet and a second air outlet, the first air outlet is opposite to the first air outlet 12, and the second air outlet is opposite to the second air outlet 13.
[0037] Please refer to Figure 4 and Figure 5The first air duct 5 is communicated with the third air duct 7, the third air duct 7 is communicated with the second air duct 6, and the second air duct 6 is communicated with the suction port of the fan 4, so that the fan 4 can not only directly suck the air flow in the second air duct 6 when operating, but also drive the air flow in the first air duct 5 and the third air duct 7 to flow into the second air duct 6, thereby driving the air flow in the first air duct 5, the second air duct 6 and the third air duct 7 to flow at the same time, which is beneficial to heat dissipation of the first heat source 2 and the second heat source 3. In the embodiment, the size of the first driving plate 21 is smaller than the size of the second driving plate 22, so that the side edge of the first driving plate 21 and the side wall of the shell 1 form a channel communicating the first air duct 5 and the third air duct 7. In addition, the second driving plate 22 is provided with a notch 221 on both ends in the length direction of the shell 1 and the other end in the width direction, and the notch 221 communicates the third air duct 7 and the second air duct 6, so that the air flow in the first air duct 5 and the third air duct 7 can enter the second air duct 6 from the notch 221.
[0038] Please refer to Figure 4 and Figure 5 The second heat source 3 further comprises a second heat sink 32, and the second heat sink 32 is used for heat dissipation of light source chips on the light machine module 31. In the embodiment, the light machine module 31 comprises a first light source chip, a second light source chip and a third light source chip, and the second heat sink 32 comprises a first heat dissipation part 321 and a second heat dissipation part 322. One end of the first heat dissipation part 321 is fixedly connected with the first light source chip, and the other end of the first heat dissipation part 321 is arranged between the first air outlet and the first air outlet 12, so that the air flow blown out from the first air outlet can flow through the first heat dissipation part 321 and dissipate heat of the first heat dissipation part 321. The second light source chip and the third light source chip are connected with one end of the second heat dissipation part 322, and the end of the second heat dissipation part 322 away from the second light source chip is arranged between the second air outlet and the second air outlet 13, so that the air flow blown out from the second air outlet can flow through the second heat dissipation part 322 and dissipate heat of the first heat dissipation part 321. The second heat sink 32 can dissipate heat of the light source chips by using the wind of the fan 4 air outlet, which is beneficial to improve the heat dissipation effect of the light source chips.
[0039] Please refer to Figure 4 and Figure 5In addition, the fan 4 is spaced apart from the bottom wall of the shell 1 and forms a fourth air duct 8, the first air duct 5 is communicated with the air inlet 11, and the second suction port of the fan 4 is communicated with the fourth air duct 8, so that the fan 4 can suck the air flow outside the projection device through the fourth air duct 8. Since the first suction port of the fan 4 sucks the air flow that has completed heat exchange from the first air duct 5, the second air duct 6 and the third air duct 7, the temperature of the air flow at the exhaust port of the fan 4 is high, and it is difficult to efficiently cool the second heat sink 32. Therefore, the air flow outside the projection device is sucked through the second suction port and mixed with the air flow that has completed heat exchange, so as to reduce the temperature of the air flow at the exhaust port of the fan 4, thereby improving the cooling effect of the second heat sink 32.
[0040] Please refer to Figure 2 and Figure 4 The second heat source 3 further comprises a third heat sink 33, and the light engine module 31 further comprises a driving unit, and the third heat sink 33 is arranged at the driving unit. One end of the third heat sink 33 away from the driving unit is arranged at the air inlet 11 of the shell 1 and located at one side of the fan 4. By arranging the third heat sink 33 at the air inlet 11 of the shell 1 and located at one side of the fan 4, the air flow entering the second air duct 6 and the fourth air duct 8 from the air inlet 11 can exchange heat with the third heat sink 33 when the fan 4 is running, thereby achieving heat dissipation of the driving unit.
