[0001] The utility model belongs to the technical field of computer graphics card heat dissipation modules, and particularly relates to a computer graphics card heat dissipation module which is convenient to assemble. Background Art

[0002] The main function of the heat dissipation module is to effectively dissipate the heat generated by the graphics card during operation, preventing the graphics card from malfunctioning or its performance from degrading due to overheating. As a high-performance component in a computer, the GPU, video memory and other core components of the graphics card generate a large amount of heat during high-intensity operations. If the heat cannot be dissipated in time, it will cause the graphics card to overheat, thereby affecting its performance and stability.

[0003] Air cooling is the most common heat dissipation method for computer graphics card heat dissipation modules, which is achieved through the combination of heat sinks and fans. The advantages of air cooling are low cost, simple structure and easy maintenance. In the process of using the existing heat dissipation modules, the following problems exist:

[0004] When assembling the heat sink and the fan of the existing air-cooled graphics card heat dissipation module, multiple bolts need to be used for installation respectively to achieve the assembly between the two. The assembly efficiency is low and the disassembly and assembly are inconvenient. Content of the Utility Model

[0006] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a computer graphics card heat dissipation module which is convenient to assemble. This heat dissipation module aims to solve the technical problems that when assembling the heat sink and the fan of the existing air-cooled graphics card heat dissipation module, multiple bolts need to be used for installation respectively to achieve the assembly between the two, with low assembly efficiency and inconvenient disassembly and assembly.

[0007] (2) Technical Solutions

[0008] To solve the above technical problems, the utility model provides such a computer graphics card heat dissipation module which is convenient to assemble. The heat dissipation module includes a fin module, a metal strip, a fan housing and fan blades. The upper surface of the fin module is connected with a metal strip. The surface of the fin module is provided with a fan housing, and the fan housing is internally fitted with fan blades;

[0009] The surface of the fin module is connected with a guide rod. The side surface of the fan housing is connected with a connecting block. A guide hole is opened on the surface of the connecting block. A bearing is internally fitted in the fan housing. A bidirectional lead screw is connected through the bearing. A thread sleeve is sleeved on the surface of the bidirectional lead screw. A hook is connected to the bottom side surface of the thread sleeve. A first slider is connected to the upper surface of the thread sleeve. A first chute is opened on the inner wall of the fan housing close to the first slider.

[0010] When using the heat dissipation module of this technical solution, the fan housing drives the guiding hole to be sleeved on the surface of the guiding rod through the connecting block. When the inner wall of the fan housing is close to the surface of the fin module, rotate the bidirectional lead screw. When the bidirectional lead screw rotates, it can drive the threaded sleeve to move horizontally through the threaded connection relationship. The horizontal movement of the threaded sleeve can drive the hook to move horizontally. When the end parts of the two hooks respectively move to the bottom side of the metal strip, the fan housing can be installed on the surface of the fin module through the hooks and the metal strip at this time.

[0011] Preferably, the connecting block and the guiding rod form a sliding connection through the guiding hole. The fan housing can drive the guiding hole to be sleeved on the surface of the guiding rod through the connecting block, so as to limit the position of the fan housing.

[0012] Furthermore, the bidirectional lead screw and the bearing form a rotating structure, and the bidirectional lead screw and the threaded sleeve are in threaded connection. Under the limiting action of the first slider and the first chute, when the bidirectional lead screw rotates, it can drive the threaded sleeve to move horizontally through the threaded connection relationship.

[0013] Furthermore, the first slider and the fan housing form a sliding connection through the first chute. When the threaded sleeve is subjected to a force, it can drive the first slider to slide inside the first chute, so as to limit the movement direction of the threaded sleeve.

[0014] Furthermore, a second chute is provided on the inner wall of the fan housing. A dust-proof cover is embedded in the fan housing. A second slider is connected to the side surface of the dust-proof cover close to the second chute. A fixing hole is provided on the side surface of the dust-proof cover. A fixing plug is inserted into the fan housing. A limiting block is connected to the surface of the fixing plug. A spring strip is connected between the limiting block and the inner wall of the fan housing, and the spring strip is sleeved on the surface of the fixing plug.

[0015] Furthermore, the second slider and the fan housing form a sliding connection through the second chute. The dust-proof cover can drive the second slider to slide downward inside the second chute, so as to limit the position of the dust-proof cover.

[0016] Furthermore, the fixing plug and the limiting block are of an integral structure, and an elastic telescopic structure is formed between the limiting block and the spring strip. When the fixing plug is squeezed, it can squeeze the spring strip through the limiting block. When the dust-proof cover drives the fixing hole to move to the end of the fixing plug, the spring strip drives the fixing plug to reset through the limiting block, and the reset of the fixing plug can be inserted into the fixing hole, so as to install the dust-proof cover on the surface of the fan blade.

[0017] (1) Beneficial effects

[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0019] In this utility model, the fan housing is sleeved on the surface of the guide rod through the connecting block driving the guide hole. When the inner wall of the fan housing is close to the surface of the fin module, the bidirectional lead screw is rotated. When the bidirectional lead screw rotates, it can drive the threaded sleeve to move horizontally through the threaded connection relationship. The horizontal movement of the threaded sleeve can drive the hook to move horizontally. When the end parts of the two hooks respectively move to the bottom side of the metal strip, at this time, the fan housing can be installed on the surface of the fin module through the hook and the metal strip, so as to facilitate the assembly between the fan housing and the fin module;

[0020] In this utility model, when the dust cover moves to the inclined surface of the fixed insertion rod, the fixed insertion rod is squeezed and can drive the limiting block to move horizontally and compress the spring strip. When the dust cover drives the fixed hole to move to the end of the fixed insertion rod, at this time, the spring strip squeezes the limiting block and the fixed insertion rod to reset through its own elastic force. The reset of the fixed insertion rod can be inserted into the interior of the fixed hole, so that the dust cover can be installed on the surface of the fan blade, thereby dust can be prevented through the dust cover, avoiding dust from entering the internal of the heat dissipation module, and thus reducing the heat dissipation efficiency of the heat dissipation module.

Detailed Embodiment

[0028] This specific implementation is a computer graphics card heat dissipation module that is easy to assemble. Its structural schematic diagram is as follows Figure 1-6 shown. The heat dissipation module includes a fin module 1, a metal strip 2, a fan housing 3, and fan blades 4. A metal strip 2 is connected to the upper surface of the fin module 1. A fan housing 3 is arranged on the surface of the fin module 1, and fan blades 4 are fitted and installed inside the fan housing 3;

[0029] A guide rod 5 is connected to the surface of the fin module 1. A connecting block 6 is connected to the side surface of the fan housing 3. A guide hole 7 is formed on the surface of the connecting block 6. A bearing 8 is fitted and installed inside the fan housing 3. A bidirectional lead screw 9 penetrates through the inside of the bearing 8. A thread sleeve 10 is sleeved on the surface of the bidirectional lead screw 9. A hook 11 is connected to the bottom side surface of the thread sleeve 10. A first slider 12 is connected to the upper surface of the thread sleeve 10. A first sliding groove 13 is formed on the inner wall of the fan housing 3 close to the first slider 12.

[0030] Among them, the connecting block 6 and the guide rod 5 form a sliding connection through the guide hole 7. The bidirectional lead screw 9 and the bearing 8 form a rotating structure. The bidirectional lead screw 9 and the thread sleeve 10 are in a threaded connection. The first slider 12 and the fan housing 3 form a sliding connection through the first sliding groove 13.

[0031] In addition, a second sliding groove 14 is formed on the inner wall of the fan housing 3. A dust-proof cover 15 is fitted inside the fan housing 3. A second slider 16 is connected to the side surface of the dust-proof cover 15 close to the second sliding groove 14. A fixing hole 17 is formed on the side surface of the dust-proof cover 15. A fixing plug 18 is inserted into the inside of the fan housing 3. A limiting block 19 is connected to the surface of the fixing plug 18. A spring strip 20 is connected between the limiting block 19 and the inner wall of the fan housing 3. The spring strip 20 is sleeved on the surface of the fixing plug 18.

[0032] Moreover, the second slider 16 and the fan housing 3 form a sliding connection through the second sliding groove 14. The fixing plug 18 and the limiting block 19 are of an integral structure. The limiting block 19 and the spring strip 20 form an elastic telescopic structure.

[0033] Working principle: When using the device of this technical solution, when assembling the fin module 1 and the fan housing 3, first, the fan housing 3 drives the guide hole 7 to be sleeved on the surface of the guide rod 5 through the connecting block 6. When the inner wall of the fan housing 3 is close to the surface of the fin module 1, at this time, the bidirectional lead screw 9 can be rotated. Under the limiting action of the first slider 12 and the first sliding groove 13, when the bidirectional lead screw 9 rotates, it can drive the thread sleeve 10 to move horizontally through the threaded connection relationship. The horizontal movement of the thread sleeve 10 can drive the hook 11 to move horizontally. When the end parts of the two hooks 11 respectively move to the bottom side of the metal strip 2, at this time, the fan housing 3 can be installed on the surface of the fin module 1 through the hook 11 and the metal strip 2;

[0034] The dust cover 15 can drive the second slider 16 to slide downward inside the second chute 14. When the dust cover 15 moves to the inclined surface of the fixed insertion rod 18, the fixed insertion rod 18 is squeezed and can drive the limit block 19 to move horizontally. The horizontal movement of the limit block 19 can compress the spring strip 20. When the dust cover 15 drives the fixing hole 17 to move to the end of the fixed insertion rod 18, at this time, the spring strip 20 can squeeze the limit block 19 to reset through its own elastic force. The reset of the limit block 19 can drive the fixed insertion rod 18 to reset, and the reset of the fixed insertion rod 18 can be inserted into the inside of the fixing hole 17, so that the dust cover 15 can be installed on the surface of the fan blade 4, thereby dust prevention can be achieved through the dust cover 15.

[0035] All technical features in this embodiment can be freely combined according to actual needs.
