[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] This utility model embodiment provides a heat dissipation device 100, such as Figures 1 to 7As shown, the heat dissipation device 100 includes a shell body 1, a fin assembly 3, and a heat spreader 2. One side of the shell body 1 is used to connect a heat source, and the fin assembly 3 is disposed on the other side of the shell body 1. The fin assembly 3 includes multiple heat dissipation fins 31 arranged side-by-side, with adjacent fins 31 interlocking. The heat spreader 2 is disposed between the shell body 1 and the fin assembly 3 to uniformly transfer heat from the heat source on the shell body 1 to the fin assembly 3.

[0029] Specifically, one side of the shell body 1 is used to connect to a heat source to absorb heat from the heat source. The fin assembly 3 is disposed on the other side of the shell body 1, and a heat dissipation plate 2 is disposed between the shell body 1 and the fin assembly 3. Thus, the heat dissipation plate 2 can efficiently and evenly transfer the heat absorbed by the shell body 1 to each heat dissipation fin 31 of the fin assembly 3, thereby improving the heat transfer efficiency of the shell body 1 and the uniformity of heat dissipation of the fin assembly 3. This allows the heat dissipation fins 31 to quickly dissipate the heat generated by the heat source to the surrounding environment. Furthermore, multiple heat dissipation fins 31 are arranged side-by-side, with adjacent fins 31 interlocking, allowing for easy assembly of multiple heat dissipation fins 31 into the fin assembly 3. Compared to the existing method of milling heat dissipation fins 31 into a heat sink base, this embodiment effectively reduces the manufacturing difficulty and cost of the fin assembly 3. It is worth mentioning that both the shell body 1 and the heat dissipation fins 31 are made of highly thermally conductive materials to ensure the thermal conductivity of the shell body 1 and the heat dissipation efficiency of the heat dissipation fins 31. For example, high thermal conductivity materials can be aluminum alloys and copper alloys.

[0030] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figures 4 to 7 As shown, the heat dissipation fin 31 includes a first heat dissipation fin 311, the first heat dissipation fin 311 is provided with a first fastening part 3111, the first fastening part 3111 is provided with a first fastening hole 3111a, and the first fastening part 3111 is fastened to the first fastening hole 3111a of the adjacent heat dissipation fin 31.

[0031] Specifically, the first heat sink 311 is provided with a first fastening part 3111, and the first fastening part 3111 has a first fastening hole 3111a. The first fastening part 3111 is fastened to the first fastening hole 3111a of the adjacent heat sink fin 31, so that multiple heat sink fins 31 can be arranged side by side and adjacent heat sink fins 31 can be fastened together, thereby facilitating the assembly of the fin assembly 3. In addition, the fastening part 3111 is fastened to the first fastening hole 3111a of the adjacent heat sink fin 31, so that the first heat sink fins 311 of the adjacent heat sink fins 31 can form an equal heat dissipation interval. Thus, on the one hand, the first heat sink 311 can dissipate heat efficiently through the heat dissipation interval, and on the other hand, it can ensure the uniformity of heat dissipation of the first heat sink 311, and avoid excessive heat in some areas of the first heat sink 311.

[0032] More specifically, the first fastening part 3111 is trapezoidal in shape, and the first fastening part 3111 has a first fastening wall 3111b and a second fastening wall 3111c that come into contact with each other. Thus, when multiple heat dissipation fins 31 are arranged side by side, the hole wall of the first fastening hole 3111a can better cooperate with the first fastening wall 3111b and the second fastening wall 3111c of the first fastening part 3111, providing better resistance and thus enhancing the stability of the fastening of the first fastening part 3111 and the first fastening hole 3111a, so as to ensure the stability of the fin assembly 3 structure.

[0033] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figures 4 to 7 As shown, the first heat sink 311 is also provided with a first limiting block 3112. The first fastening hole 3111a includes a first hole segment 3111a1 and a second hole segment 3111a2. The first limiting block 3112 is located on the side of the first hole segment 3111a1 away from the second hole segment 3111a2, and the first limiting block 3112 is perpendicular to the first fastening part 3111. The first fastening part 3111 is fastened to the first hole segment 3111a1 of the adjacent heat sink fin 31, and the second hole segment 3111a2 is fastened to the first limiting block 3112 of the adjacent heat sink fin 31, so as to limit the first fastening part 3111.

[0034] Specifically, the first limiting block 3112 is located on the side of the first hole segment 3111a1 away from the second hole segment 3111a2. When the first fastening part 3111 is fastened to the first hole segment 3111a1 of the adjacent heat sink fin 31, the second hole segment 3111a2 can be fastened to the first limiting block 3112 of the adjacent heat sink fin 31. Since the first limiting block 3112 is set perpendicular to the first fastening part 3111, the first limiting block 3112 can limit the first fastening part 3111 of the adjacent heat sink fin 31 in the direction perpendicular to the first fastening part 3111, thereby preventing the first fastening part 3111 from detaching from the first hole segment 3111a1 of the adjacent heat sink fin 31 and increasing the stability of the connection between the heat sink fins 31.

[0035] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figures 4 to 7 As shown, the heat dissipation fin 31 also includes a second heat dissipation fin 312 for connecting the heat exchange plate 2.

A second fastening hole 3121a is provided on the second fastening part 3121. The second fastening part 3121 is fastened to the second fastening hole 3121a of the adjacent heat dissipation fin 31.

[0036] Specifically, the second heat sink 312 connects the heat dissipation fins 31 and the heat spreader 2, allowing the heat spreader 2 to evenly transfer heat from the heat source to each heat dissipation fin 31. Furthermore, the second heat sink 312, in conjunction with the first heat sink 311, forms two heat dissipation points, improving the heat dissipation efficiency of the heat dissipation fins 31. In addition, the second heat sink 312 is provided with a second fastening portion 3121, which has a second fastening hole 3121a. The second fastening portion 3121 engages with the second fastening hole 3121a of the adjacent heat dissipation fin 31. Thus, the second fastening portion 3121, in conjunction with the first fastening portion 3111, increases the stability of the fastening between the heat dissipation fins 31.

[0037] More specifically, the second fastening portion 3121 is trapezoidal in shape and has a third fastening wall 3121b and a fourth fastening wall 3121c that are close to each other. Thus, when multiple heat dissipation fins 31 are arranged side by side, the hole wall of the second fastening hole 3121a can better cooperate with the third fastening wall 3121b and the fourth fastening wall 3121c of the second fastening portion 3121, providing better resistance and enhancing the stability of the fastening between the second fastening portion 3121 and the second fastening hole 3121a, thereby ensuring the stability of the fin assembly 3 structure.

[0038] It is worth mentioning that each heat dissipation fin 31 needs to be fastened to the first fastening hole 3111a of the adjacent heat dissipation fin 31 through the first fastening part 3111, and the second fastening part 3121 needs to be fastened to the second fastening hole 3121a of the adjacent heat dissipation fin 31, so that multiple heat dissipation fins 31 are assembled into fin assembly 3. Then, the second heat dissipation fin 312 of each heat dissipation fin 31 is welded to the heat dissipation plate 2 to ensure the stability of the connection between the fin assembly 3 and the heat dissipation plate 2.

[0039] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figures 4 to 7 As shown, the second heat sink 312 is also provided with a second limiting block 3122. The second fastening hole 3121a includes a third hole segment 3121a1 and a fourth hole segment 3121a2. The second limiting block 3122 is located on the side of the third hole segment 3121a1 away from the fourth hole segment 3121a2. The second limiting block 3122 is perpendicular to the second fastening part 3121. The second fastening part 3121 is fastened to the third hole segment 3121a1 of the adjacent heat sink fin 31. The fourth hole segment 3121a2 is fastened to the second limiting block 3122 of the adjacent heat sink fin 31 to limit the second fastening part 3121.

[0040] Specifically, the second limiting block 3122 is located on the side of the third hole segment 3121a1 away from the fourth hole segment 3121a2. When the second fastening part 3121 is fastened to the third hole segment 3121a1 of the adjacent heat sink fin 31, the fourth hole segment 3121a2 can be fastened to the second limiting block 3122 of the adjacent heat sink fin 31. Since the second limiting block 3122 is set perpendicular to the second fastening part 3121, the second limiting block 3122 can limit the second fastening part 3121 of the adjacent heat sink fin 31 in the direction perpendicular to the second fastening part 3121, thereby preventing the second fastening part 3121 from detaching from the first hole segment 3111a1 of the adjacent heat sink fin 31 and increasing the stability of the connection between the heat sink fins 31.

[0041] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figures 4 to 7 As shown, the heat dissipation fins 31 are integrally formed.

[0042] Specifically, the heat dissipation fins 31 are integrally formed. The heat dissipation fins 31 are formed by stamping process to form the first heat dissipation fin 311, the first fastening part 3111, the second heat dissipation fin 312 and the second fastening part 3121. This can ensure the integrity and stability of the structure of the heat dissipation fins 31, while simplifying the manufacturing process of the heat dissipation fins 31 and improving production efficiency.

[0043] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figures 1 to 3 As shown, the heat spreader 2 is provided with a heat-conducting medium (not shown in the figure), which is used to transfer the heat from the heat source to the heat dissipation fins 31.

[0044] Specifically, the heat spreader 2 contains a heat-conducting medium with excellent thermal conductivity, which can quickly and evenly transfer heat from the heat source to the fin assembly 3, thereby accelerating the heat dissipation efficiency of the fin assembly 3. Specifically, on the side of the heat spreader 2 connected to the shell body 1, the heat-conducting medium can quickly absorb the heat from the heat source transferred by the shell body 1 and vaporize into steam. Then, it moves towards the side of the heat spreader 2 connected to the fin assembly 3 and condenses into liquid, thus quickly and evenly transferring heat from the heat source to the fin assembly 3.

[0045] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figures 1 to 3 As shown, the shell body 1 has a first mounting groove 11 on the side near the heat spreader 2, and the second heat sink 312 and the heat spreader 2 are both located in the first mounting groove 11.

[0046] Specifically, by having the second heat sink 312 and the heat spreader 2 disposed within the first mounting groove 11, the second heat sink 312 and the heat spreader 2 can be in close contact with the housing body 1. This allows the housing body 1 to effectively conduct heat from the heat source to the heat spreader 2 and the second heat sink 312, and ensures the stability of the connection between the heat spreader 2 and the housing body 1. Furthermore, it allows the fin assembly 3 and the heat spreader 2 to be compactly installed together, saving space and improving the overall compactness and aesthetics of the heat dissipation device 100.

The bottom of the second mounting groove 12 is close to the bottom of the first mounting groove 11. The second mounting groove 12 is used to fix the heat source.

[0048] Specifically, a second mounting groove 12 is provided on the side of the shell body 1 away from the heat spreader 2. The bottom of the second mounting groove 12 is close to the bottom of the first mounting groove 11, which can effectively reduce the distance between the first mounting groove 11 and the second mounting groove 12, so that the heat source in the second mounting groove 12 can quickly transfer heat to the heat spreader 2, thereby enabling the heat spreader 2 to quickly absorb heat and evenly transfer it to the fin assembly 3 for heat dissipation.

[0049] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figures 1 to 3 As shown, the second mounting slot 12 has multiple heat dissipation holes 121 on its wall, which are used to dissipate heat from the heat source.

[0050] Specifically, the second mounting groove 12 has multiple heat dissipation holes 121 on its groove wall. The heat dissipation holes 121 help to ventilate the second mounting groove 12.
