[0019] Compared with the prior art, the present invention provides a projector optical machine with an internal heat dissipation duct dual-circulation structure, comprising a housing, wherein a lens module, an image display module, and a focusing tube are sequentially arranged inside the housing from left to right. The left and right ends of the housing are respectively provided with openings, a lens is arranged in the opening at the left end of the housing, and a light source board is arranged in the opening at the right end.

[0030] As Figure 1 and 2 For the convenience of description, the "up", "down", "left", "right", "front", "back" orientation reference in the present application is based on the orientation shown in the accompanying drawings; Figure 2

[0031] A projector light machine with internal heat dissipation air duct double circulation structure, comprising a shell 1, the inside of the shell 1 is sequentially provided with a lens module 2, an image display module 3 and a light collecting cylinder 4 from left to right, the left and right ends of the shell 1 are respectively provided with openings, the opening at the left end of the shell 1 is provided with a lens 5, and the opening at the right end is provided with a light source plate 6,

[0032] The lens module 2 and the image display module 3 are provided with through holes penetrating the upper and lower ends thereof,

[0033] A first through hole is arranged on the upper side wall of the right end of the shell 1, a first heat dissipation fan 7 is arranged in the first through hole, the upper and lower ends of the first heat dissipation fan 7 are respectively provided with air inlets, a wind deflector 8 is arranged on the air outlet at the left end of the first heat dissipation fan 7, the air outlet of the wind deflector 8 is communicated with the opening at the upper end of the image display module 3, a second through hole is arranged on the lower side wall of the right end of the shell 1, a first radiator 9 is arranged outside the second through hole, gaps are respectively arranged between the inner wall of the first radiator 9 and the lens module 2, the image display module 3 and the light collecting cylinder 4, a second radiator 10 is arranged outside the first through hole, gaps are respectively arranged between the inner wall of the second radiator 10 and the lens module 2, the wind deflector 4 and the first heat dissipation fan 7,

[0034] A third radiator 11 is arranged on the right side of the light source plate 6, and a second heat dissipation fan 12 is arranged on the right side of the third radiator 11,

[0035] ​In this way, the wind coming out of the first cooling fan 7 will be divided into two paths after passing through the air guide cover 8 and the interior of the image display module 3. One path is guided by the first radiator 9 to the right and flows through the gap between the first radiator 9 and the image display module 3 and the focusing tube 4, and then returns to the first cooling fan 7 from the air inlet on the lower side wall of the first cooling fan 7. The other path is guided by the first radiator 9 upward through the through hole at the lower end of the lens module 2 into the lens module 2 and then flows from the through hole at the upper end of the lens module 2 to the second radiator 10, and then under the guidance of the second radiator 10, it flows to the right through the gap between the second radiator 10 and the lens module 2, the air guide cover 4 and the first cooling fan 7, and returns to the first cooling fan 7 from the air inlet on the upper side wall of the first cooling fan 7. Therefore, by using one first cooling fan 7, two air paths for heat dissipation can be realized inside the projector optical machine, thereby efficiently dissipating heat for components such as the lens module 2, the image display module 3 and the focusing tube 4.

[0036] In this embodiment, in order to further improve the efficiency of heat dissipation for components such as the lens module 2, the image display module 3, and the focusing tube 4, and to prevent the airflow generated by the first cooling fan 7 from flowing to other places, the design requires that the two ends of the air guide cover 8 be sealedly connected to the air outlet of the first cooling fan 7 and the image display module 3.

[0037] The upper and lower ends of the lens module 2 and the four sides of the lower end of the image display module 3 are sealed and connected to the inner wall of the housing 1 respectively.

[0038] In this embodiment, the lens 5, the first radiator 9, the second radiator 10 and the third radiator 11 are respectively sealed and connected to the housing 1, which not only prevents external dust from entering the interior of the projector optical machine and affecting the projection effect, but also further ensures the effect of its internal heat dissipation operation and avoids air leakage.

[0039] In this embodiment, the third radiator 11 includes a heat sink 1101, a heat pipe 1102 and several heat sinks 1103. The heat sink 1101 is fixed on the shell 1, and its left side wall is fitted between the right side wall of the light source board 6, which is conducive to the heat generated by the light source board 6 to be more directly and quickly conducted to the heat sink 1101. One end of the heat pipe 1102 is connected to the right side wall of the heat sink 1101, and several heat sinks 1103 are mounted on the outside of the heat pipe 1102. Accordingly, the heat on the heat sink 1101 will be conducted to the heat sink 1103 via the heat pipe 1102 to achieve the purpose of heat dissipation.

[0040] Furthermore, a heat pipe embedding groove is provided on the right side wall of the heat dissipation plate 1101 along the front-to-back direction. The heat pipe 1102 is in a "U" shape. One end of the heat pipe 1102 is embedded in the heat pipe embedding groove. Several "L"-shaped heat dissipation fins 1103 are mounted on the outside of the heat pipe 1102. The design of the heat pipe embedding groove increases the direct contact area between the heat dissipation plate 1101 and the heat pipe 1102. Similarly, the "U"-shaped heat pipe 1103 and the "L"-shaped heat dissipation fins 1103 increase the contact area between the heat pipe 1102 and the heat dissipation fins 1103, thereby correspondingly improving the heat conduction and heat dissipation effects of the entire third radiator 11.

[0041] In this embodiment, a second cooling fan mounting bracket 13 is provided on the right end of the housing 1, and the second cooling fan mounting bracket 13 is mounted on the right side of the heat sink 1103. The second cooling fan 12 is mounted on the right side wall of the second cooling fan mounting bracket 13.

[0042] Furthermore, an air inlet is provided on the left side wall of the second cooling fan 12 and an air outlet is provided on the front side wall. In this way, the heat from the heat sink 1103 will enter the second cooling fan 12 from the air inlet on the left side wall of the second cooling fan 12, and then be discharged to the outside of the projector optical machine through the air outlet on the front side wall of the second cooling fan 12, thereby achieving the purpose of dissipating the heat generated by the light source panel 6 and the entire projector optical machine.

[0043] In this embodiment, the shell 1 includes an upper shell 101 and a lower shell 102, and the upper shell 101 and the lower shell 102 are sealed together. The shell 1 adopts an upper and lower split structure. On the basis of the sealed connection between the upper and lower shells, it not only does not affect the heat dissipation effect of the entire projector optical machine, but also the design of the split structure greatly facilitates the disassembly and assembly operations of the entire projector optical machine, effectively improving the production efficiency of the projector optical machine.

[0044] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
