At the same time, the first fixing plate 13 and the second fixing plate 14 can also fix the two adjacent edges of the second heat sink 22, so that the two adjacent edges of the first heat sink 21 and the second heat sink 22 will not shake, thereby achieving the purpose of stability.

[0034] like Figure 1-Figure 8 As shown, in the present embodiment: a telescopic fixing member 3 or an adjustable fixing member 4 is respectively provided on the opposite sides of the first fixing plate 13 and the second fixing plate 14, the telescopic fixing member 3 can be telescoped along the side of the box body 1 to facilitate the installation of the heat sink 2 in place, and then the telescopic fixing member 3 is reset to fix one side of the first heat sink 21 and the second heat sink 22; the adjustable fixing member 4 can not only fix the heat sink 2, but also fix the telescopic fixing member 3, so that the adjustable fixing member 4 and the telescopic fixing member 3 can simultaneously fix the other two adjacent sides of the first heat sink 21 and the second heat sink 22 without shaking, thereby achieving the purpose of stability, so as to realize the stable installation of the heat sink 2. The above technical scheme can not only be installed quickly, but also be disassembled quickly, and the dust attached to the heat sink part can be easily cleaned, thereby improving the heat dissipation effect and extending its service life.

[0035] like Figure 1-Figure 8 As shown, in this embodiment: a movable cavity 16 is opened on the side of the box body 1, the adjusting fixing member 4 is connected to the movable cavity 16, and includes a fourth fixing plate 41, a second abutment plate 42 and a movable plate 43, wherein: the fourth fixing plate 41 is slidably connected to the side of the box body 1, and is used to fix the heat sink 2, and a gap for accommodating the heat sink 2 is left between the fourth fixing plate 41 and the side of the box body 1; the second abutment plate 42 is slidably connected to the side of the box body 1, and is located in the gap formed by the fourth fixing plate 41 and the side of the box body 1, and the second abutment plate 42 is used to abut the heat sink 2; the movable plate 43 is slidably connected in the movable cavity 16, and is fixedly connected to the free ends of the fourth fixing plate 41 and the second abutment plate 42, and the movable plate 43 is used to drive the fourth fixing plate 41 and the second abutment plate 42.

[0036] Through the above technical solution, one edge of the first heat sink 21 is inserted into the gap between the fourth fixing plate 41 and the side of the box body 1. After the second abutment plate 42 is reset, it can fix one edge of the first heat sink 21 by abutting. At the same time, the fourth fixing plate 41 fixes the second heat sink 22.

[0037] like Figure 1-Figure 8As shown, in this embodiment: a handle 45 is provided on the outer surface of the fourth fixing plate 41, and the handle 45 is used to drive the fourth fixing plate 41 to move. A receiving groove 18 is opened on the side of the box body 1, and the receiving groove 18 is used to receive the handle 45 moved into place.

[0038] The process of adjusting the fixing member 4 to fix the heat sink 2 is as follows:

[0039] Before installing the heat sink 2, firstly, the fourth fixing plate 41 is driven by the handle 45 to slide along the side of the box body 1, and the fourth fixing plate 41 drives the moving plate 43 to slide along the moving cavity 16. During the sliding process of the moving plate 43, the second abutment plate 42 and the fourth fixing plate 41 are driven to slide synchronously until the second abutment plate 42 and the fourth fixing plate 41 completely leave the mounting hole 12, providing space for the installation of the heat sink 2. Then, the heat sink 2 is placed in the mounting hole 12. During the placement process, the telescopic fixing member 3 is driven to slide until the heat sink 2 is completely entered into the mounting hole 12, and then, the first fixing plate 13 or the fourth fixing plate 41 is moved to the first fixing plate 13 or the fourth fixing plate 41. The heat sink 2 is moved toward the second fixing plate 14 until it is stuck in the gap between the first fixing plate 13 or the second fixing plate 14 and the side of the box body 1. Then, the heat sink 2 is moved toward the second fixing plate 14 or the first fixing plate 13 until it is stuck in the gap between the second fixing plate 14 or the first fixing plate 13 and the side of the box body 1. Finally, the fourth fixing plate 41 is driven to reset by the handle 45. The fourth fixing plate 41 fixes the first heat sink 21 and presses against the second heat sink 22 at the same time. The second pressing plate 42 presses against the first heat sink 21. The fourth fixing plate 41 and the second pressing plate 42 fix the heat sink 2.

[0040] like Figure 1-Figure 8 As shown, in the present embodiment: the width of the movable plate 43 is greater than that of the fourth fixed plate 41 and the second abutment plate 42, so as to limit the sliding range of the fourth fixed plate 41 and the second abutment plate 42; the length of the fourth fixed plate 41 is greater than that of the second abutment plate 42, so as to facilitate respectively abutting and fixing the second heat dissipation plate 22 and the first heat dissipation plate 21; the thickness of the first heat dissipation plate 21 matches the gap between the fourth fixed plate 41 and the side of the box body 1, so as to facilitate the fourth fixed plate 41 to clamp and fix the position of the first heat dissipation plate 21.

[0041] like Figure 1-Figure 8As shown, in this embodiment: a telescopic cavity 15 is opened on the side of the box body 1, the telescopic fixing member 3 is connected to the telescopic cavity 15, and includes a third fixing plate 31, a first abutment plate 32, a telescopic plate 33 and a spring 34, wherein: the third fixing plate 31 is slidably connected to the side of the box body 1, and is used to fix the heat sink 2, and a gap for accommodating the heat sink 2 is left between the third fixing plate 31 and the side of the box body 1; the first abutment plate 32 is slidably connected to the side of the box body 1, and is located in the gap formed by the third fixing plate 31 and the side of the box body 1, and the first abutment plate 32 is used to abut the heat sink 2; the telescopic plate 33 is slidably connected in the telescopic cavity 15, and is fixedly connected to the free ends of the third fixing plate 31 and the first abutment plate 32, and the telescopic plate 33 is used to drive the third fixing plate 31 and the first abutment plate 32 to slide; a plurality of springs 34 are provided and are located between the telescopic plate 33 and the inner wall of the telescopic cavity 15, and the spring 34 is used to return the telescopic plate 33.

[0042] Through the above technical solution, one edge of the first heat sink 21 is inserted into the gap between the third fixing plate 31 and the side of the box body 1. After the first abutment plate 32 is reset, it can fix one edge of the first heat sink 21 by abutting. At the same time, the third fixing plate 31 fixes the second heat sink 22.

[0043] The process of fixing the telescopic fixing member 3 to the heat sink 2 is as follows:

[0044] The adjusting fixing piece 4 provides space for the installation of the heat sink 2. When the heat sink 2 is placed in the mounting hole 12, the first heat sink 21 is inserted into the gap between the third fixing plate 31 and the side of the box body 1, and the third fixing plate 31 is pushed to slide. The third fixing plate 31 pushes the telescopic plate 33 to slide along the telescopic cavity 15, and at the same time compresses the spring 34 and drives the first abutment plate 32 to slide. After the heat sink 2 completely enters the mounting hole 12 and moves toward the first fixing plate 13 or the second fixing plate 14, the spring 34 pushes the third fixing plate 31 and the first abutment plate 32 to slide together through the telescopic plate 33. The third fixing plate 31 abuts against the second heat sink 22 and is embedded in the first heat sink 21. The first abutment plate 32 abuts against the first heat sink 21. When the heat sink 2 finishes moving, the third fixing plate 31 and the first abutment plate 32 jointly fix the heat sink 2.

[0045] like Figure 1-Figure 8 As shown, in the present embodiment: the width of the telescopic plate 33 is greater than the third fixed plate 31 and the first abutment plate 32, so the sliding range of the third fixed plate 31 and the first abutment plate 32 can be limited; the height of the third fixed plate 31 is greater than the first abutment plate 32, so it is convenient to respectively abut and fix the first heat dissipation plate 21 and the second heat dissipation plate 22; the thickness of the first heat dissipation plate 21 matches the gap between the third fixed plate 31 and the side of the box body 1, so it is convenient for the third fixed plate 31 to clamp and fix the position of the first heat dissipation plate 21.

[0046] like Figure 1-Figure 8As shown, in the present embodiment: a horizontal connecting cavity 17 is opened between the movable cavity 16 and the telescopic cavity 15, and a limiting plate 44 is slidably connected in the connecting cavity 17. One end of the limiting plate 44 is fixedly connected to the movable plate 43, and the other end extends into the telescopic cavity 15 to limit the position of the telescopic plate 33. After the limiting plate 44 enters the telescopic cavity 15, it will clamp the telescopic plate 33 to limit the movement of the telescopic plate 33. By fixing the third fixed plate 31 and the first abutment plate 32, the first heat sink 21 and the second heat sink 22 are firmly fixed.

[0047] The process of adjusting the fixing member 4 to fix the telescopic fixing member 3 is as follows:

[0048] After the telescopic fixing member 3 fixes the heat sink 2, the adjusting fixing member 4 is reset. During the resetting process of the movable plate 43, the limiting plate 44 is driven to move along the connecting cavity 17. When the movable plate 43 finishes moving, the limiting plate 44 enters the telescopic cavity 15 and clamps the telescopic plate 33. By fixing and limiting the telescopic plate 33, the third fixing plate 31 and the first abutting plate 32 are fixed, thereby fixing the edges of the first heat sink 21 and the second heat sink 22.

[0049] like Figure 1-Figure 8 As shown, in this embodiment: a box door 11 is rotatably connected to the box body 1, and the design of the box door 11 facilitates the inspection and replacement of components inside the box body 1.

[0050] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
