It can be understood that the projector 1000 provided in the embodiment of the present application may be a desktop projector, a portable projector, a floor-type projector, a suspension-type projector, a home projector, an intelligent projector, and the like, and the specific structure of the projector 1000 where the heat dissipation assembly 100 is located is not strictly limited. Because the fan 12 of the fan module 10 is disposed inside the main body 11, the main body 11 has the air outlet 111 and the opening 112, and the first connecting plate 31 of the connecting panel 30 is disposed on the opening 112 of the main body 11 and seals the opening 112 of the main body 11, thereby forming the main body 11 having the air outlet 111, the air flow is driven to flow when the fan 12 rotates, and the air flow driven when the fan 12 rotates is forced to flow through the air outlet 111 of the main body 11 because the opening 112 of the main body 11 is sealed by the first connecting plate 31. In some embodiments, the connecting panel 30 includes a first connecting plate 31 and a second connecting plate 32 connected together, the shape of the first connecting plate 31 may be determined according to the shape of the opening 112 of the main body 11, but it is required to seal the opening 112 of the main body 11, the shape of the second connecting plate 32 is not particularly required for the fin module 20 disposed on the second connecting plate 32, the first connecting plate 31 and the second connecting plate 32 may be connected by welding, sleeving, or gluing, or in other embodiments, the first connecting plate 31 and the second connecting plate 32 are integrally formed to form the connecting panel 30.
Referring to fig. 2, the fin module 20 includes at least two fins 21 arranged in parallel at intervals, a flow guide 22 is formed between adjacent fins 21, the flow guide 22 of the fin module 20 is disposed toward the air outlet 111 of the main body 11, and a peripheral side of the fin module 20 facing the air outlet 111 is flush with a peripheral side of the air outlet 111 to seal a joint between the fin module 20 and the air outlet 111, so as to prevent an airflow passing through the air outlet 111 of the main body 11 from leaking from the peripheral side of the joint between the fin module 20 and the air outlet 111 when flowing through the fin module 20, thereby causing noise. Meanwhile, because the fins 21 of the fin module 20 are arranged at intervals and in parallel, the airflow flowing out from the air outlet 111 can uniformly pass through the flow guide channels 22 between the adjacent fins 21, and thus flows out of the heat dissipation assembly 100. In some embodiments, the adjacent fins 21 are spaced at equal intervals, and the fins 21 are arranged in parallel, so that the guide channels 22 are spaced at equal intervals, and the air flow passing through each guide channel 22 is more uniform, thereby further reducing the noise generated by the heat dissipation assembly 100 of the projector 1000 during heat dissipation. Further, in some embodiments, the adjacent fins 21 are linearly arranged, so that the fin module 20 can be seamlessly abutted to the air outlet 111 towards the side of the air outlet 111, each flow guide channel 22 is disposed opposite to the air outlet 111, and the airflow flows straight and directly opposite to the inlet of the flow guide channel 22 and flows out through the outlet of the flow guide channel 22, thereby improving the heat dissipation efficiency of the heat dissipation assembly 100 and further reducing the noise generated by the airflow flow. Of course, in other embodiments, the spacing distances between the adjacent fins 21 of the fin module 20 may be different but the adjacent fins 21 are arranged in parallel, or the spacing distances between the adjacent fins 21 of the fin module 20 are different and not arranged in parallel, or the spacing distances between the adjacent fins 21 of the fin module 20 are equal but the adjacent fins 21 are not arranged in parallel, and the spacing distances and the arrangement modes between the fins 21 of the fin module 20 are determined according to actual situations. Meanwhile, the fins 21 may be fins 21 having the same shape and structure, or fins 21 having different shapes and structures.
As shown in fig. 2, in some embodiments, the main body 11 further has an air inlet 113, and the air flow enters the fan module 10 through the air inlet 113, and forms an air flow under the action of the fan 12, and the air flow flows through the air outlet 111 and is transmitted to the outside of the heat dissipation assembly 100 through the flow guide 22. The fan 12 may be a centrifugal fan, and when the air flow enters the fan 12 disposed in the main body 11 through the air inlet 113, the air flow is formed into an air flow under the action of the centrifugal fan 12, and is transmitted to the air outlet 111, and flows through the flow guide 22 of the fin module 20, and then flows out of the heat dissipation assembly 100. Of course, in other embodiments, the fan 12 may also be an axial flow fan 12 disposed in the main body 11, and the airflow enters the main body 11 through the air inlet 113, flows through the axial direction of the fan blade, and flows out of the heat dissipation assembly 100 through the air outlet 111 and the flow guide 22 of the fin module 20.
Optionally, as shown in fig. 3, in some embodiments, the first connecting plate 31 is further provided with a vent hole 311, the airflow can enter the fan module 10 through the air inlet 113 or the vent hole 311, and forms an airflow under the action of the fan 12, and the airflow flows through the air outlet 111 and is transmitted to the outside of the heat dissipation assembly 100 through the flow guide 22. Meanwhile, since the fan 12 is rotated for a long time, the fan 12 itself generates heat, and the heat generated by the fan 12 itself can be emitted out of the main body 11 through the vent holes 311.
In some embodiments, as shown in fig. 4, the main body 11 includes a first cover plate 114 and a sidewall 115, one side of the sidewall 115 is connected to a portion of the edge of the first cover plate 114, so that the portion of the edge of the first cover plate 114 that is not surrounded forms the air outlet 111 with the sidewall 115, and the other side of the sidewall 115 is surrounded forms the opening 112 of the main body 11. It can be understood that, when the opening 112 of the main body 11 formed by enclosing the other side of the side wall 115 is sealed by the first connecting plate 31, the other side of the side wall 115 is enclosed on the first connecting plate 31, so that the edge of the portion of the first cover plate 114 that is not enclosed forms the air outlet 111 with the portion of the side wall 115 that is not enclosed by the first connecting plate 31. The peripheral side of the fin module 20 facing the air outlet 111 is flush with the peripheral side of the air outlet 111, in other words, the peripheral side of the fin module 20 facing the air outlet 111 is flush with the edge of the portion of the first cover plate 114 not surrounded, the sidewall 115, and the portion of the first connecting plate 31 not surrounded, respectively, so as to close the gap at the joint between the air outlet 111 and the fin module 20, thereby blocking the air flow from being discharged from the joint between the air outlet 111 and the fin module 20, guiding the air flow into the flow guide channel 22 of the fin module 20, and reducing the noise of the heat dissipation assembly 100. Of course, in other embodiments, the main body 11 may have other specific structures, and is not limited to the above structure.
As shown in fig. 5, the first cover plate 114 has an arc-shaped edge 116 bent toward a side away from the opening 112, and the arc-shaped edge 116 is flush with an upper side of the fin module 20 near the air outlet 111. It can be understood that the first cover plate 114 has an arc-shaped edge 116 that is bent toward a side away from the opening 112 of the main body 11, and an arc center of the arc-shaped edge 116 is located at a side of the first cover plate 114 away from the opening 112 of the main body 11, so that an air outlet area of the air outlet 111 is continuously increased along with the bending of the arc-shaped edge 116, and after the air flow enters the fin module 20 through the air outlet 111, the air outlet area is too small to generate a lot of noise. When the arc-shaped edge 116 is flush with the upper side of the fin module 20 close to the air outlet 111, the arc-shaped edge 116 is a portion of the first cover plate 114 not surrounded by the sidewall 115, in other words, the edges of the arc-shaped edge 116, the sidewall 115, and the first connecting plate 31 are not surrounded to form a peripheral edge of the air outlet 111, and the peripheral edge of the fin module 20 facing the air outlet 111 is flush with the peripheral edge of the air outlet 111, so that when the air flows through the air outlet 111, the air outlet area is continuously increased and enters the flow guide channel 22 of the fin module 20, noise generated when the heat dissipation assembly 100 dissipates heat is reduced, contact area between the air flow and the fin module 20 is increased, and heat dissipation efficiency is improved.
As shown in fig. 6, the main body 11 further includes a second cover plate 117, and the second cover plate 117 is connected to the first cover plate 114 and attached to a side of the fin module 20 facing away from the second connecting plate 32 to cover at least a portion of the upper ventilation opening 223 of the flow guide 22. It is understood that fin module 20 includes at least two fins 21 spaced apart and arranged in parallel, and flow guide 22 is formed between adjacent fins 21. As shown in fig. 7, the side of the flow guide 22 facing the air outlet 111 is a near-wind end 221, the side facing away from the air outlet 111 is a far-wind end 222, the side of the flow guide 22 close to the second connecting plate 32 is a lower vent 224, and the side facing away from the second connecting plate 32 close to the first cover plate 114 is an upper vent 223. The second cover plate 117 is connected to the first cover plate 114 and covers at least part of the upper ventilation opening 223 of the flow guide channel 22, when the second cover plate 117 partially covers the upper ventilation opening 223 of the flow guide channel 22, when the airflow passes through the junction between the peripheral side of the fin module 20 facing the air outlet 111 and the peripheral side of the air outlet 111, the airflow cannot flow out from the junction under the block of the second cover plate 117 partially covering the upper ventilation opening 223 of the flow guide channel 22, so that noise when the airflow passes through is reduced, and the sealing performance of the heat dissipation assembly 100 is improved. When the second cover plate 117 completely covers the upper vents 223 of the flow guide channel 22, the airflow flowing through the fin module 20 cannot be discharged through the upper vents 223 of the flow guide channel 22, but flows out from the far wind end 222 of the flow guide channel 22, and flows from the near wind end 221 of the flow guide channel 22 to the far wind end 222 in the process of flowing out of the airflow, so that the contact area between the airflow and the fins 21 is increased, and the heat dissipation area is effectively increased.
In some embodiments, as shown in fig. 7 and 8, one end of the second connecting plate 32 is connected to the first connecting plate 31, and the other end is flush with the side of the fin module 20 away from the air outlet 111, so that the connecting panel 30 simultaneously closes the opening 112 of the main body 11 and the lower vent 224 of the flow guide 22. It can be understood that the fin module 20 includes at least two fins 21 arranged in parallel at intervals, and a flow guide 22 is formed between adjacent fins 21, so that the side of the flow guide 22 facing the air outlet 111 is a near-wind end 221, the side facing away from the air outlet 111 is a far-wind end 222, the side of the flow guide 22 close to the second connecting plate 32 is a lower vent 224, and the side facing away from the second connecting plate 32 close to the first cover 114 is an upper vent 223. The other end of the second connecting plate 32 is flush with the side of the fin module 20 away from the air outlet 111, and the fin module 20 is disposed on the second connecting plate 32, and both ends of the second connecting plate are respectively connected to the first connecting plate 31 and the side of the fin module 20 away from the air outlet 111, in other words, the second connecting plate 32 is disposed at the lower vent 224 of the flow guide 22 of the fin module 20 and blocks the airflow in the flow guide 22 from flowing to the lower vent 224. Further, in some embodiments, the second connecting plate 32 covers the flow guiding channels 22 of all adjacent fins 21 and seals all the lower ventilation openings 224, so that most of the airflow flows out of the heat dissipation assembly 100 through the far wind end 222 of the flow guiding channels, thereby reducing the noise of the heat dissipation assembly 100.
In some embodiments, as shown in fig. 8, the fin module 20 further includes a clip 23, the clip 23 is disposed on the fin 21 at the end of the fin module 20, and the sidewall 115 of the main body 11 is provided with a fixing block 118, so that the clip 23 is clipped on the fixing block 118.

In some embodiments, the fin module 20 includes at least two fins 21 arranged at intervals and arranged in parallel, the shape and structure of each fin 21 are the same, and the positions of the through holes 211 on the fins 21 are also the same, so that the heat pipe 40 sequentially passes through the through holes 211 of each fin 21 to penetrate through the fin module 20, and the heat on the heat pipe 40 is transferred to the fins 21, and when the fan 12 of the fan module 10 rotates, the air flow is driven to flow through the flow guide 22 of the fin module 20 through the air outlet 111 to take away the heat on the fins 21, thereby achieving the effects of cooling and dissipating heat.

When the projector 1000 projects, the heat generating device 210 inside the housing 200 of the projector 1000 generates heat, the heat is transferred to one end of the heat pipe 40, and then the heat is transferred to the through holes 211 of the fins 21, the fin module 20 absorbs the heat on the heat pipe 40, and the heat is taken away by the airflow flowing through the flow guide 22 of the fin module 20 under the action of the fan 12, so as to achieve the purpose of heat dissipation.
