Referring to fig. 1, an embodiment of the application provides a projector 1000, which includes a housing 300, a fan 200, and a fin module 100, wherein the fan 200 is disposed inside the housing 300, the fan 200 is connected to the fin module 100 and blows air toward the fin module 100, and the housing 300 has an air outlet 220 and an air inlet 210. Referring to fig. 2 and 3, the fin module 100 includes at least two fins 10 arranged at an interval and arranged in parallel, a flow guide channel 20 is formed between adjacent fins 10, the flow guide channel 20 faces the air outlet 220, the fins 10 include a heat sink 11 and a first heat sink 12 arranged on one side of the heat sink 11, and the first heat sink 12 is located in the flow guide channel 20, wherein the first heat sink 12 includes a first curved surface end 121, a connecting portion 122, and a second curved surface end 123 connected in sequence, so that an air flow enters the housing 300 through the air inlet 210, an air flow is formed under the action of the fan 200 and flows to the flow guide channel 20, and the air flow passes through the first curved surface end 121, the connecting portion 122, and the second curved surface end 123 of the first heat sink 12 in sequence in the flow guide channel 20, and then flows out of the housing 300 through the air outlet. It can be understood that, in the using process of the projector 1000, the inside of the projector 1000 generates heat, and after the fin module 100 absorbs the heat, the air flow entering the housing 300 is converted into the wind flow under the action of the fan 200, and then part of the heat on the fin module 100 is dissipated in the form of convection, in the process of convection heat dissipation, the heat dissipation area is mainly determined by the size of the surface area of the fins 10, and the larger the surface area is, the better the heat dissipation effect is; the smaller the surface area, the poorer the heat dissipation effect. In this embodiment, the first heat sink 12 is disposed on one side of the heat sink 11, so that the heat dissipation area of the fin module 100 is increased, meanwhile, the airflow entering the casing 300 forms an airflow under the action of the fan 200 and flows to the airflow channel 20, and heat dissipation is performed by convection, and the first heat sink 12 is located in the airflow channel 20, so that the contact area between the fin module 100 and the airflow is also increased, and the heat dissipation effect is better improved. In addition, as shown in fig. 2, since the first heat sink 12 has the first curved surface end 121, the connecting portion 122 and the second curved surface end 123, when the wind flow enters the flow guide channel 20, the wind flow contacts the curved surface portion of the first curved surface end 121 first, because the curved surface has a certain flow guide effect, the wind flow passes through the connecting portion 122 under the flow guide of the first curved surface end 121, and when the wind flow flows out in the flow guide channel 20, the wind flow flows out from the curved surface of the second curved surface end 123, while the heat dissipation area and the contact area of the fin module 100 and the wind flow are increased, the flow speed of the wind flow is ensured to the maximum extent, so that the flow speed of the wind flow is not affected by the first heat sink 12, and the reduction of the heat dissipation efficiency is prevented.

In some embodiments, referring to fig. 2, the number of the first heat dissipation elements 12 is at least two, and all the first heat dissipation elements 12 are disposed on one side of the heat dissipation plate 11 at the same time. It can be understood that the heat dissipation area is mainly determined by the surface area of the fins 10 during the convection heat dissipation process, and the larger the surface area is, the better the heat dissipation effect is, therefore, by providing at least two first heat dissipation members 12 at one side of the heat dissipation plate 11, the surface area of the fin module 100 can be effectively increased, the space can be reasonably utilized, and the heat dissipation area can be further increased in the limited flow guide 20.

Specifically, referring to fig. 2, adjacent first heat dissipation elements 12 are spaced apart and arranged in parallel on one side of the heat dissipation fin 11, so that the first heat dissipation elements 12 separate the flow guide channels 20. It can be understood that after the fins 10 of the fin module 100 are overlapped, a flow guide channel 20 is formed between the adjacent fins 10, so that the first heat dissipation member 12 is located between the flow guide channels 20 of the fin module 100, because the first curved end 121, the connection portion 122, and the second curved end 123 of the first heat dissipation member 12 have a certain thickness, the flow guide channel 20 can be separated by using the first heat dissipation member 12, when the number of the first heat dissipation members 12 is two, the two first heat dissipation members 12 separate the flow guide channel 20, and at the same time, the two first heat dissipation members 12 are spaced and arranged in parallel on one side of the heat dissipation member 11, so that the air flow entering the flow guide channel 20 takes out the heat from the same direction at the air outlet 220 of the housing 300 under the flow guide of the two first heat dissipation members 12, and the heat dissipation is relatively concentrated, thereby improving the heat dissipation efficiency. When the number of the first heat dissipation members 12 is three, the adjacent first heat dissipation members 12 are disposed at intervals and arranged in parallel on one side of the heat dissipation plate 11, and in some embodiments, the adjacent first heat dissipation members 12 are disposed at equal intervals and arranged in parallel on one side of the heat dissipation plate 11, so as to ensure that the air flows flowing through the separated air guide channels 20 between the adjacent first heat dissipation members 12 are relatively even, increase the heat dissipation surface area of the fins 10, increase the air guide effect, ensure that all parts of the fin module 100 are uniformly contacted with the air flow, and increase the service life of the fin module 100. Of course, in other embodiments, the adjacent first heat dissipation elements 12 may also be disposed on one side of the three heat dissipation fins 11 at unequal intervals, in the case of irregular arrangement, for example, the adjacent first heat dissipation elements 12 are disposed on the heat dissipation fins 11 at intervals from large to small or from small to large. In addition, when the number of the first heat dissipation elements 12 is four or more, the adjacent first heat dissipation elements 12 are arranged on one side of the heat dissipation fin 11 at intervals and in parallel, and so on, which will not be described herein.

Referring to fig. 4, in some embodiments, the first curved surface end 121 and the second curved surface end 123 of the first heat dissipation element 12 are in a quarter-spherical shape, the connection portion 122 is in a semi-cylindrical shape, and spherical center points of the first curved surface end 121 and the second curved surface end 123 are all disposed toward the connection portion 122, so that the first curved surface end 121, the connection portion 122, and the second curved surface end 123 of the first heat dissipation element 12 are connected to form the first heat dissipation element 12.

It can be understood that, after the airflow forms the airflow flowing to the flow guide channel 20 under the action of the fan 200, part of the airflow in the flow guide channel 20 sequentially passes through the first through hole 1211 of the first curved surface end 121, the hollow 1221 inside the connecting portion 122, and the second through hole 1231 on the second curved surface end 123 and flows out of the first heat dissipation member 12, and the other part of the airflow sequentially contacts the first curved surface end 121, the connecting portion 122, and the second curved surface end 123 from the outside of the first heat dissipation member 12 in the flow guide channel 20, so that the airflow can respectively pass through the inside and the outside of the first heat dissipation member 12 when flowing through the flow guide channel 20, and the contact area between the airflow and the first heat dissipation member 12 is increased, in other words, both the inner surface and the outer surface of the first heat dissipation member 12 are in contact with the airflow, the surface of the fin 10 is increased, and the heat dissipation area of the fin module 100 is increased, thereby improving the heat dissipation efficiency.

In some embodiments, referring to fig. 7 and 8, a second heat dissipation member 13 is further disposed on the other side of the heat dissipation member 11, such that the second heat dissipation member 13 and the first heat dissipation member 12 are disposed on two sides of the heat dissipation member 11, respectively. It can be understood that one side of the heat sink 11 is provided with the first heat sink 12, and the other side is further provided with the second heat sink 13, so that the second heat sink 13 and the first heat sink 12 are respectively disposed at two sides of the heat sink 11, thereby further increasing the surface area of the fin module 100 to increase the heat dissipation area, and further utilizing the space of the flow guide 20 between the adjacent fins 10.

In some embodiments, referring to fig. 7 and 8, the number of the second heat dissipation elements 13 is at least two, all the second heat dissipation elements 13 are disposed on the side of the heat dissipation fins 11 away from the first heat dissipation element 12, and the second heat dissipation elements 13 and the first heat dissipation elements 12 are disposed in a staggered manner on two sides of the same heat dissipation fin 11, so that the first heat dissipation element 12 of one heat dissipation fin 11 and the second heat dissipation element 13 of an adjacent heat dissipation fin 11 in the flow guide channel 20 are disposed in a staggered manner. It can be understood that, when the number of the first heat dissipation elements 12 disposed on one side of the heat dissipation fin 11 is at least two, and the number of the second heat dissipation elements 13 disposed on the other side of the heat dissipation fin 11 is at least two, the first heat dissipation elements 12 and the second heat dissipation elements 13 of the same heat dissipation fin 11 are located in the flow guide channels 20 of different adjacent fins 10, and the first heat dissipation elements 12 and the second heat dissipation elements 13 are respectively disposed on two sides of the same heat dissipation fin 11, under the condition that the surface area of the fin module 100 is further increased, it is ensured that the first heat dissipation elements 12 or the second heat dissipation elements 13 on the same side of the heat dissipation fin 11 are not distributed too densely. In addition, the second heat dissipation elements 13 and the first heat dissipation elements 12 are arranged on two sides of the heat dissipation fins 11 in a staggered manner, and the first heat dissipation elements 12 and the second heat dissipation elements 13 are respectively located in the flow guide channels 20 formed by the heat dissipation fins 11 and different adjacent fins 10, so that the first heat dissipation elements 12 of one heat dissipation fin 11 in the flow guide channels 20 and the second heat dissipation elements 13 of the adjacent heat dissipation fins 11 are arranged in a staggered manner, at least more than two first heat dissipation elements 12 and more than two second heat dissipation elements 13 are arranged in the same flow guide channel 20, a certain surface area of the fins 10 is increased in a limited space of the flow guide channel 20, the heat dissipation efficiency is improved, and the flow of the air flow in the flow guide channel 20. Of course, when the number of the first heat dissipation elements 12 and the second heat dissipation elements 13 exceeds two at the same time, the arrangement manner of the first heat dissipation elements 12 and the second heat dissipation elements 13 respectively arranged on two sides of the same heat dissipation element 11 is analogized, and the description is omitted here.

In some embodiments, as shown in fig. 9, the connection portion 122 includes a first connection section 122a, a connection middle section 122b, and a second connection section 122c, a side of the first connection section 122a away from the connection middle section 122b is connected to the first curved surface end 121, a side of the second connection section 122c away from the connection middle section 122b is connected to the second curved surface end 123, and two ends of the connection middle section 122b are respectively bent to connect the first connection section 122a and the second connection section 122c, so that the first connection section 122a and the second connection section 122c are disposed parallel to each other on the heat sink 11. Optionally, when the connecting middle section 122b is obliquely disposed on one side of the heat sink 11, two sides of the connecting middle section 122b are respectively bent and connected to the first connecting section 122a and the second connecting section 122c, and the first connecting section 122a and the second connecting section 122c are disposed on the heat sink 11 along the horizontal direction X, so that the overall structure of the first heat sink 12 is in a zigzag shape, when the wind current passes through the flow guide 20, the wind current contacts the first curved surface end 121 and passes through the first connecting section 122a, and then changes the flow direction under the limitation of the connecting middle section 122b, and flows out from the flow guide 20 through the second connecting section 122c, and the length of the first heat sink 12 is structurally increased by the zigzag-shaped first heat sink 12, and since the first heat sink 12 has a certain thickness and width, the surface area of the fin module 100 is further increased in a limited space. Alternatively, the first connecting section 122a and the second connecting section 122c may not be disposed along a straight line on the heat sink 11, and the connecting section 122 may be disposed vertically on one side of the heat sink 11, which may also increase the surface area of the fin module 100 in a limited space.

Alternatively, as shown in fig. 10, in some embodiments, the side surface of the heat sink 11 includes a protrusion 11a and a groove 11b connected in sequence, so that the heat sink 11 forms a tooth-shaped heat sink 11 with two-sided irregularities, wherein the first heat sink 12 is disposed on the groove 11b of one side of the heat sink 11. In some embodiments, the heat sink 11 is a vertical and flat heat sink 11, but is a heat sink 11 comprising a protrusion 11a and a groove 11b connected in sequence, wherein the heat sink 11 comprises a first heat dissipating surface 111 and a second heat dissipating surface 112, the first heat dissipating surface 111 and the second heat dissipating surface 112 are not coplanar, so that the first heat dissipating surface 111 and the second heat dissipating surface 112 are connected in sequence to form the heat sink 11 into a tooth-shaped heat sink 11 with two uneven sides, thereby forming the protrusion 11a and the groove 11b on the side surface of the heat sink 11, and the first heat dissipating member 12 is disposed on the groove 11b on one side of the heat sink 11. It is understood that the shape of the flow guide 20 between the adjacent fins 10 will also form a new structure of the flow guide 20 along with the unevenness of the side surfaces of the fins 11, but since the wind flows into the fin module 100 while passing through the flow guide 20, the wind flows in the flow guide 20 are not affected by the shapes of the fins 11 on both sides. On the contrary, the uneven toothed heat sink 11 is also used to increase the surface area of the fin module 100 in a limited space, so as to further increase the heat dissipation area of the fins 10 contacting with air, thereby improving the heat dissipation efficiency. Alternatively, in other embodiments, the protrusion 11a and the groove 11b of the heat sink 11 may have other structures, for example, the second heat dissipating surface 112 of the heat sink 11 and the two adjacent first heat dissipating surfaces 111 thereof are perpendicularly connected to each other to form a rectangular groove 11b or protrusion 11a, so that the side surface of the heat sink 11 is formed by the rectangular groove 11b and the rectangular protrusion 11a connected to one side. For another example, the second heat dissipating surface 112 of the heat sink 11 and the two first heat dissipating surfaces 111 that ring with them are connected to each other obliquely to form the trapezoidal groove 11b or other structures such as the protrusion 11a, and the specific structure of the protrusion 11a and the groove 11b on the side surface of the heat sink 11 is not strictly limited.

It can be understood that, when the projector 1000 projects, the heat generating device 310 inside the housing 300 of the projector 1000 generates heat, the heat is transferred to one end of the heat pipe 320, and then the heat is transferred to the through holes 14 of the fins 10, the fin module 100 absorbs the heat on the heat pipe 320, and the heat is taken away by the airflow flowing through the flow guide 20 of the fin module 100 under the action of the fan 200, so as to achieve the purpose of heat dissipation. Specifically, the heat pipe 320 includes an evaporation section and a condensation section, the evaporation section is connected to the heat generating device 310, the condensation section sequentially passes through the through holes 14 of the fins 10, when the evaporation section of the heat pipe 320 is heated, liquid in the capillary wick evaporates and vaporizes, vapor flows to the condensation section under a slight pressure difference to release heat and condense into liquid, and the liquid flows back to the evaporation section along the porous material under the action of capillary force, so as to achieve the purpose of transmitting the heat of the heat generating device 310 to the fin module 100.
