However, traditional projectors currently have the following disadvantages:

[0003] Despite numerous improvements by engineers in the industry, conventional projectors are still relatively large and cannot fully meet users' requirements for portability and compactness. Therefore, reducing the overall size of projectors has always been a goal pursued by engineers in the industry. Utility Model Content

[0024] like Figure 1 and 2 As shown,

[0025] A novel heat sink for a projector includes heat pipes 1 and heat-conducting plates 2. Multiple heat pipes 1 and two heat-conducting plates 2 are arranged side-by-side, with the two heat-conducting plates 2 spaced apart. A thermally conductive film is wrapped around the multiple heat pipes 1 and the two heat-conducting plates 2 to form a heat sink 3. Multiple first heat dissipation fins 4 are arranged side-by-side on the upper side of the heat sink 3. The heat pipes 1 are made of copper, the heat-conducting plates 2 are made of aluminum or copper, the thermally conductive film is aluminum foil, and the first heat dissipation fins 4 are made of aluminum. The multiple first heat dissipation fins 4 are bonded to the surface of the thermally conductive film using thermally conductive adhesive.

[0026] The heat pipe 1, heat plate 2, first heat dissipation fin 4, and heat dissipation film are integrated together. The straight heat pipe 1, compared to the curved heat pipe in traditional projector heat sinks, makes the heat pipe 1, heat plate 2, first heat dissipation fin 4, and heat dissipation film integrated into a plate-like structure. Its overall thickness is much smaller than that of traditional projector heat sinks. Therefore, the overall size of the projector using the heat sink provided by this utility model can be further reduced.

[0027] In this embodiment, two first through holes 21 are respectively provided on the two heat-conducting plates 2, and second through holes are respectively provided on the heat-conducting film at the positions corresponding to the four first through holes 21. The four first through holes 21 are arranged in a rectangular shape. The four first through holes 21 are located at one end of the heat sink 3, and multiple first heat dissipation fins 4 are located at the other end of the heat sink 3. Through the first through holes 21 on the heat-conducting plates 2 and with the corresponding fixing screws, the heat sink 3 can be directly connected to the light-emitting plate in the projector. Therefore, the heat on the light-emitting plate can be directly transferred to the heat sink 3 and the first heat dissipation fins 4. With the help of the corresponding cooling fan, the heat on the light-emitting plate can be dissipated, thereby achieving the purpose of heat dissipation of the light-emitting plate.

[0028] In this embodiment, the multiple heat pipes 1 have the same length, and the two heat plates 2 have the same length and are shorter than the length of the heat pipes 1. In this way, the multiple heat pipes 1 and the two heat plates 2 are arranged side by side and wrapped with a heat-conducting film to form a very regular rectangular plate structure, which is beneficial to reducing the overall volume of the heat sink.

[0029] In this embodiment, a first heat dissipation fin 4 is provided on the upper side of the heat dissipation plate 3, and a second heat dissipation fin 5 is provided on the lower side. The second heat dissipation fin 5 is also made of aluminum. By providing the first heat dissipation fin 4 and the second heat dissipation fin 5 on the upper and lower sides of the heat dissipation plate 3 respectively, the heat dissipation efficiency of the entire heat dissipation device is effectively improved.

[0030] In this embodiment, multiple first heat dissipation fins 4 are formed by folding a single heat dissipation fin multiple times. This simplifies the manufacturing and installation of multiple first heat dissipation fins 4, while ensuring heat dissipation effect. Therefore, the heat sink for projectors provided by this utility model has a simpler overall structure than the traditional heat sink for projectors, and is also smaller in size. This is beneficial for engineers in the industry to further reduce the overall size of projectors, thereby producing products that are more popular with users.

[0031] In this embodiment, the second heat dissipation fin 5 consists of a base plate 51, a top plate 52, and multiple spacer plates 53 arranged side-by-side between the base plate 51 and the top plate 52. The spacer plates 53 are spaced at equal intervals. The upper surface of the top plate 52 is connected to the lower surface of the heat dissipation plate 3. The gaps between the multiple spacer plates 53 form airflow channels, which not only facilitates smooth airflow but also increases the contact area between the airflow and the second heat dissipation fin 5, thereby improving the heat dissipation efficiency of the second heat dissipation fin 5.

[0032] 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.

[0033] 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.
