[0026] In one embodiment of the present invention, Figures 1 to 4 As shown, a combined fan frame structure is provided, including a base 10 and a heat sink 20. The heat sink 20 is arranged in at least two groups. Two adjacent groups of heat sinks 20 are distributed on the base 10 up and down, and a snap-on component 30 for quick disassembly is provided between the two adjacent groups of heat sinks 20. The heat sink 20 includes a mounting seat 21 and an upper cover 22. The mounting seat 21 is arranged on the base 10. The upper cover 22 is arranged on the mounting seat 21. A limiting component 40 for limiting is provided between the mounting seat 21 and the base 10. A pressing component 50 corresponding to the limiting component is provided on the mounting seat 21. The pressing component 50 conflicts with the limiting component 40, and the pressing component 50 is used to separate the mounting seat 21 from the base 10.

[0027] In this embodiment, the heat sink 20 is provided in two groups and is distributed on the base 10 in the upper and lower parts. The two groups of heat sinks 20 are connected by a snap-fit ​​component 30, so that the two groups of heat sinks 20 can be quickly connected or disassembled, simplifying the steps of installation and disassembly and improving assembly efficiency. In other embodiments, the number of heat sinks 20 can be determined according to actual production needs, as long as it can meet the actual usage.

[0028] During disassembly, the two adjacent groups of heat sinks 20 are rotated so that the protruding block 31 of the snap component 30 on the front group of heat sinks 20 is rotated to the entrance port 322 of the connecting groove 32 of the snap component 30 on the rear group of heat sinks 20, and the protruding block 31 is disengaged from the entrance port 322, so that the two adjacent groups of heat sinks 20 are quickly disassembled, and the disassembly steps are simplified, which facilitates the replacement or cleaning of the heat sinks 20. At the same time, after disassembly, by pressing the pressing component 50, the limiting piece 41 and the limiting groove 42 of the limiting component 40 between the mounting seat 21 and the base 10 are separated from each other, which facilitates the disassembly between the mounting seat 21 and the base 10, and facilitates the staff to clean the inside of the heat sink 20 or replace the base 10 and the mounting seat 21, thereby improving the convenience of the fan frame structure.

[0029] Furthermore, the snap-fit ​​component 30 includes a protruding block 31 and a connecting groove 32. The protruding block 31 is provided at the bottom end of the base 10. The connecting groove 32 is provided at the top end of the mounting seat 21, and the protruding block 31 is slidably connected in the connecting groove 32. When two adjacent groups of heat sinks 20 are disassembled, the two groups of heat sinks 20 are rotated, and the protruding block 31 slides from the end of the connecting groove 32 to the entrance end of the connecting groove 32, and the protruding block 31 is disengaged from the connecting groove 32, thereby realizing the rapid disassembly of the two adjacent groups of heat sinks 20, simplifying the disassembly steps, facilitating the replacement or cleaning of the heat sinks 20, and improving the convenience of the fan frame structure.

[0030] Furthermore, the bottom end of the protruding block 31 is connected to a boss 311 extending outward. One end of the connecting groove 32 is provided with an entry port 322 corresponding to the boss 311. The protruding block 31 drives the boss 311 to enter from the entry port 322, and the two adjacent groups of heat sinks 20 rotate with each other, and the outer side of the protruding block 31 moves along the connecting groove 32 to the other end of the connecting groove 32, and the two adjacent groups of heat sinks 20 fit tightly. In this embodiment, the boss 311 and the protruding block 31 form a "T"-shaped structure, and the cross-section of the connecting groove 32 is also a "T"-shaped structure, so that the boss 311 and the protruding block 31 can be stably engaged with the connecting groove 32, thereby improving the connection stability between the two adjacent groups of heat sinks 20.

[0031] When two adjacent groups of heat sinks 20 are disassembled, the two groups of heat sinks 20 are rotated, and the raised block 31 drives the boss 311 to slide from the end of the connecting groove 32 to the entrance port 322, and the boss 311 is disengaged from the entrance port 322, thereby realizing rapid disassembly of the two adjacent groups of heat sinks 20, simplifying the disassembly steps, facilitating replacement or cleaning of the heat sinks 20, and improving the convenience of the fan frame structure.

[0032] Furthermore, the outer diameter of the boss 311 is greater than the outer diameter of the protruding block 31. The outer diameter of the protruding block 31 is equal to the inner diameter of the connecting groove 32, and the inner diameter of the entrance 322 is equal to the outer diameter of the boss 311. By setting such dimensions, the connection between the boss 311, the protruding block 31 and the connecting groove 32 is more stable, so that the boss 311 and the protruding block 31 can be stably engaged in the connecting groove 32. The connecting groove 32 is an arc-shaped structure, so that the connecting groove 32 and the protruding block 31 can rotate stably to avoid jamming.

[0033] Furthermore, the limiting component 40 includes a limiting component 41 and a limiting groove 42. The mounting seat 21 is provided with a frame extending upward, and the limiting component 41 is provided on the frame. The limiting groove 42 is provided on the upper cover 22. The pressing component 50 is located on one side of the limiting groove 42 and conflicts with the limiting component 41. The limiting component 41 can enter or escape from the limiting groove 42. When the mounting seat 21 and the upper cover 22 are disassembled, the pressing component 50 is pressed, and the pressing component 50 pushes the limiting component 41 out of the limiting groove 42. At this time, the upper cover 22 is pulled out from the mounting seat 21, and the separation between the mounting seat 21 and the upper cover 22 can be completed, which simplifies the disassembly steps between the mounting seat 21 and the upper cover 22 and facilitates the cleaning or replacement of parts between the mounting seat 21 and the upper cover 22.

[0034] Specifically, the limiting member 41 includes an elastic portion 411 and a protruding portion 412. The elastic portion 411 is disposed on the mounting seat 21. The protruding portion 412 is disposed on the elastic portion 411, and the protruding portion 412 conflicts with the pressing component 50. The protruding portion 412 can enter or escape from the limiting groove 42. In this embodiment, the elastic portion 411 is an elastic spring sheet. Due to the elastic force of the elastic portion 411, the elastic portion 411 can drive the protruding portion 412 to reset, so that the protruding portion 412 can always be engaged in the limiting groove 42, thereby ensuring a stable connection between the mounting seat 21 and the upper cover 22.

[0035] Furthermore, a slot is provided on the mounting seat 21. The elastic part 411 is located in the slot, and a slot is formed between the elastic part 411 and the slot. By providing the slot, the friction between the elastic part 411 and the mounting seat 21 can be reduced, making it easier for the elastic part 411 to move and adjust its position.

[0036] Specifically, the mounting seat 21 is provided with four sets of circumferentially distributed guide grooves, and the upper cover 22 is provided with four sets of guide strips corresponding to the guide grooves. When the mounting seat 21 is connected to the upper cover 22, the guide strips slide along the guide grooves to improve the connection stability between the mounting seat 21 and the upper cover 22.

[0037] Specifically, the pressing component 50 includes a pressing block 51 and a pressing rod 52. The pressing rod 52 is slidably connected to the mounting seat 21 and is located on one side of the limiting member 41. One end of the pressing rod 52 passes through the mounting seat 21 and is connected to the pressing block 51. The pressing block 51 is arranged on one side of the limiting member 41, and one end of the pressing block 51 is provided with an inclined surface, which conflicts with the side surface of the limiting member 41. A spring 53 is arranged between the pressing rod 52 and the mounting seat 21, and the other end of the pressing rod 52 is connected to the limiting portion. The spring 53 is sleeved between the limiting portion and the mounting seat 21, and the spring 53 is used to drive the pressing rod 52 to reset after the pressing rod 52 is released. During disassembly, the pressure rod 52 is pressed down, and the pressure rod 52 drives the pressure block 51 to push the limiting member 41 out of the limiting groove 42, so that the limiting member 41 is disengaged from the limiting groove 42, and the upper cover 22 can be taken out from the mounting seat 21. After the pressure rod 52 is released, under the action of the spring 53, the pressure rod 52 drives the pressure block 51 to return to its original position, which is convenient for the subsequent connection between the limiting member 41 and the limiting groove 42.

[0038] Furthermore, the base 10 is provided with a heat dissipation fin 11. A heat dissipation fan 23 is provided in the mounting seat 21, and the heat dissipation fan 23 is located above the heat dissipation fin 11. By providing the heat dissipation fin 11, the heat dissipation fin 11 is fitted with the heat source, and then the heat dissipation fin 11 is transferred upward through the heat dissipation fans 23 of the multiple groups of heat dissipation seats 20, so that the heat of the heat source is gradually reduced, thereby improving the heat dissipation effect of the heat dissipation.

[0039] By providing the snap-fit ​​component 30, the limiting component 40 and the pressing component 50, during disassembly, the two adjacent groups of heat sinks 20 are rotated so that the protruding block 31 of the snap-fit ​​component 30 on the front group of heat sinks 20 is rotated to the entrance 322 of the connecting groove 32 of the snap-fit ​​component 30 on the latter group of heat sinks 20, and the protruding block 31 is detached from the entrance 322, so that the two adjacent groups of heat sinks 20 are quickly disassembled, the disassembly steps are simplified, and the replacement or cleaning of the heat sinks 20 is convenient. At the same time, after disassembly, by pressing the pressing component 50, the slot and the snap of the limiting component 40 between the mounting seat 21 and the base 10 are separated from each other, which is convenient for the disassembly between the mounting seat 21 and the base 10, and convenient for the staff to clean the inside of the heat sink 20 or replace the base 10 and the mounting seat 21, thereby improving the convenience of the fan frame structure.
