[0030] like Figures 1-4 As shown, for ease of description, the orientation references of "up", "down", "left", "right", "front" and "rear" in this utility model are attached. Figure 4 The directions shown are accurate;
[0031] A heat sink for a projector includes a front sidewall 1, a left sidewall 2, a right sidewall 3, an upper sidewall 4, and a lower sidewall 5. The front sidewall 1, left sidewall 2, right sidewall 3, upper sidewall 4, and lower sidewall 5 form a hollow cuboid with an opening at the rear. The outer surfaces of the front sidewall 1, left sidewall 2, and right sidewall 3 are respectively provided with several rows of first heat dissipation fins 6 in a horizontal direction, and the inner surfaces of the front sidewall 1, upper sidewall 4, and lower sidewall 5 are respectively provided with several rows of second heat dissipation fins 7 in a vertical direction. The heat sink provided by this utility model has a square overall shape. Compared with the original heat sink structure, it has a larger internal space and can simultaneously allow a larger volume of air to flow inside. Therefore, its internal air circulation is faster, thereby achieving the purpose of improving heat dissipation performance.
[0032] In this embodiment, several rows of first heat dissipation fins 6 located on the outer surfaces of the front sidewall 1, left sidewall 2, and right sidewall 3 are arranged in parallel, and the spacing between them is equal.
[0033] The rows of second heat dissipation fins 7 located on the inner surfaces of the front sidewall 1, upper sidewall 4, and lower sidewall 5 are arranged in parallel, and the spacing between them is equal.
[0034] Furthermore, the first heat dissipation fins 6 on the outer surfaces of the front sidewall 1, the left sidewall 2, and the right sidewall 3, and located on the same horizontal plane, are interconnected.
[0035] The second heat dissipation fins 7 on the inner surfaces of the front sidewall 1, upper sidewall 4, and lower sidewall 5, and located on the same vertical plane, are connected to each other. Therefore, several air flow channels are formed between the rows of first heat dissipation fins 6 and the columns of second heat dissipation fins 7, which not only realizes the orderly flow of air, but also guides the flow of air, greatly improving the heat dissipation effect.
[0036] In this embodiment, the several rows of first heat dissipation fins 6 located on the outer surface of the front sidewall 1 are intermittently divided into several segments, and the position and width of the intervals between the first heat dissipation fins 6 in each row are the same.
[0037] The lower ends of the rows of second heat dissipation fins 7 on the inner surface of the front sidewall 1 and the rows of second heat dissipation fins 7 on the lower sidewall 5 are intermittently divided into several segments, and the spacing and width of each row of second heat dissipation fins 7 are the same. Therefore, the air flowing on both the inner and outer sides of the heat sink can form horizontal and vertical flow channels, which increases the contact area between the air and the heat sink body, thereby improving the heat dissipation efficiency.
[0038] In this embodiment, the two ends of the rows of first heat dissipation fins 6 on the outer surface of the front sidewall 1 are rounded outwards at the connection points with the first heat dissipation fins 6 on the left sidewall 2 and the right sidewall 3 to avoid sharp corners at the connection points from accidentally injuring operators and other components.
[0039] The upper ends of the rows of second heat dissipation fins 7 on the inner surface of the front side wall 1 and the connection points of the second heat dissipation fins 7 on the upper side wall 4 are respectively set with inward rounded corners. This not only makes it easier for the heat dissipation fins to be better matched to the projector, but also makes the airflow passing through this place more stable and rapid.
[0040] In this embodiment, the outer side of the connection between the upper end of the front sidewall 1 and the lower end of the upper sidewall 4 is rounded outwards, and the inner side is rounded inwards. Similarly, this design is to allow the air in the air channel formed by the first heat dissipation fin 6 and the second heat dissipation fin 7 on both sides of the heat sink to flow more smoothly and quickly, thereby improving the heat dissipation efficiency.
[0041] In this embodiment, the front end of the lower sidewall 5, the lower end of the front sidewall 1, the lower end of the left sidewall 2, and the lower end of the right sidewall 3 are offset inward to form an inward boss 8. The second heat dissipation fin 7 is located on the lower sidewall 5 and on the inner wall of the boss 8. The lower end of the right sidewall 3, offset to the right, is provided with a groove 9 that is recessed to the left at the connection between its upper end and the lower end. The boss 8 and the groove 9 are provided to better match the connection and installation between the components on the projector, so as to make the appearance of the entire projector more compact and beautiful.
[0042] In this embodiment, the height of the rearward protrusion of the second heat dissipation fin 7 located on the inner surface of the front sidewall 1 is the same as the height of the rearward protrusion of the second heat dissipation fin 7 located on the inner wall of the boss 8. The second heat dissipation fin 7 with the same height makes it more convenient to connect the heat sink and other components of the projector.
[0043] In this embodiment, the outer side of the connection between the upper end of the boss 8 and the lower end of the front sidewall 1 is rounded inward, and the inner side is rounded outward. This design is to allow the air in the air channel formed by the second heat dissipation fin 7 inside the heat sink to flow more smoothly and quickly, thereby improving the heat dissipation efficiency.
[0044] In this embodiment, the rear edges of the left side wall 2 and the right side wall 3 are respectively provided with connecting plates 10 parallel to the front side wall 1. The upper end face of the connecting plate 10 is located above the upper side wall 4, and the lower end face is flush with the lower surface of the lower side wall 5. The rear end faces of the first heat dissipation fins 6 on the left side wall 2 and the right side wall 3 are respectively connected to the front end face of the connecting plate 10. At least one through hole 11 is provided at the upper and lower ends of the two connecting plates 10 respectively. The connection between the heat dissipation fins and other components of the projector can be realized through the through holes 11 and the corresponding screws.
[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.
[0046] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
