[0035] Please see Figures 1 to 8This embodiment provides a CPU heatsink with a grid-lit design, including a heatsink body 1, a cooling fan 2, an optical assembly, and wiring 3. The cooling fan 2 includes fan blades 21 and a fan housing 22. The inner side of the fan housing 22 is a mounting area, and a mounting base 221 is provided in the mounting area. The fan blades 21 are disposed in the mounting area and connected to the mounting base 221. The optical assembly includes a light guide inner shell 42, a light shielding ring 43, a light guide outer shell 44, and a light-emitting element 41. The outer surface of the light guide inner shell 42 is provided with a first mounting groove 421, and the inner surface of the light shielding ring 43 is provided with a plurality of first strip-shaped protrusions 431 arranged in a ring. The light-shielding ring 43 is sleeved on the light-guiding inner shell 42. The first strip-shaped protrusion 431 is placed in the first mounting groove 421. The inner surface of the light-guiding outer shell 44 is provided with a plurality of second mounting grooves 441. The outer surface of the light-shielding ring 43 is provided with a plurality of second strip-shaped protrusions 432. The light-guiding outer shell 44 is sleeved on the light-shielding ring 43. The second strip-shaped protrusions 432 are placed in the second mounting grooves 441. The light-emitting element 41 is attached to the outer surface of the fan housing 22. The light-emitting element 41 is used to provide a light source. The wire 3 is disposed on the outer surface of the heat dissipation body 1 and is used to supply power to the heat dissipation fan 2 and the optical components.
[0036] The heat sink 1 is the core component of the heat sink, used to absorb and conduct heat generated by the CPU. It is usually made of a metal material with good thermal conductivity, preferably copper, and its heat dissipation area is increased through structures such as heat sink fins. The cooling fan 2 consists of fan blades 21 and a fan housing 22. The fan blades 21 generate airflow by rotating, accelerating the airflow on the surface of the heat sink 1, thereby achieving rapid heat dissipation. The fan housing 22 provides mounting space and protection for the fan blades 21, while the annular mounting part 222 on the fan housing 22 abuts against the light guide inner shell 42, which serves to fix the optical components. The light-emitting element 41 is a light strip composed of an FPCB and LED lights, which is bonded to the outer surface of the fan housing 22 with adhesive backing. It is used to provide a light source, and the light emitted by the light-emitting element 41 realizes the lighting effect of the heat sink, increasing the product's aesthetics and personalization. The cable 3 is used to connect the external power supply to the cooling fan 2 and the light-emitting element 41. Specifically, the heat generated by the CPU during operation is transferred to the heat sink 1, which then dissipates the heat into the surrounding air. After the cooling fan 2 is started, the fan blades 21 rotate and drive the airflow, quickly removing the heat from the surface of the heat sink 1 and enhancing the heat dissipation effect. At the same time, the cable 3 obtains power from the power supply to provide power for the operation of the cooling fan 2 and the illumination of the light-emitting component 41, thus achieving the heat dissipation and lighting effects.
[0037] The light guide inner shell 42 is cylindrical in shape, with multiple hollowed-out areas at one end. These hollowed-out areas are arranged in a ring-shaped interval, creating a ring-shaped grid pattern at one end of the light guide inner shell 42. The light guide inner shell 42 is made of transparent acrylic with added inorganic diffusion powder, transparent acrylic with added organic diffusion powder, PC material with added inorganic diffusion powder, or PC material with added organic diffusion powder. The outer surface of the light guide inner shell 42 has a first mounting groove 421 for mounting a light-shielding ring 43. The light guide inner shell 42 serves to initially guide and distribute light. The light guide inner shell 42, in conjunction with the light-shielding ring 43, can block and divide light, creating a ring-shaped light effect directly above the heat sink. Simultaneously, the ring-shaped grid-like end of the light guide inner shell 42 emits a lighting effect. Specifically, the light emitted by the light-emitting element 41 is first projected onto the light-guiding inner shell 42. The light-guiding inner shell 42 utilizes its structural characteristics to initially guide and diffuse the light. The light-shielding ring 43 is installed by engaging with the first mounting groove 421 of the light-guiding inner shell 42 through the first strip-shaped protrusion 431. During the further guidance of the light, it blocks part of the light, preventing the light from being too concentrated or chaotic, thus making the final lighting effect more uniform and softer, and improving the visual experience. Through the cooperation of the light-guiding inner shell 42 and the light-shielding ring 43, the transmission and distribution of light are optimized, improving the quality of the lighting effect. The installation and engagement method of the light-guiding inner shell 42 and the light-shielding ring 43 is simple and reliable, easy to assemble, and ensures structural stability during use, preventing loosening and ensuring the consistency and stability of the lighting effect. At the same time, it also facilitates later cleaning and maintenance.
[0038] The light guide shell 44 is made of transparent acrylic, transparent acrylic with added color powder, transparent PC material, or transparent PC material with added color powder. The light guide shell 44 has multiple second mounting grooves 441, optionally six, arranged in a ring on the inner surface of the light guide shell 44. The light shielding ring 43 has multiple second strip-shaped protrusions 432, the number of which matches the number of second mounting grooves 441. The second mounting grooves 441 and the second strip-shaped protrusions 432 form a quick-release snap-fit structure, allowing the light guide shell 44 to be snapped onto the light shielding ring 43. Simultaneously, the inner light guide shell 42 and the cooling fan 2 are both housed within the light guide shell 44. The light guide shell 44 further enhances the light diffusion effect and aesthetics, making the radiator's light emission effect more dazzling and unique. At the same time, the light guide shell 44 also protects the cooling fan 2.
[0039] Please see Figure 3 , Figure 4 and Figure 7In this embodiment, the inner surface of the light-shielding ring is further provided with a third protrusion 433. One end of the light-guiding inner shell 42 has a hollow area, and the third protrusion 433 is placed in the hollow area. The opposite side walls of the third protrusion abut against the light-guiding inner shell 42. There are multiple third protrusions 433, which are distributed in a ring. When the light-shielding ring 43 is sleeved on the light-guiding inner shell 42, the third protrusion 433 is placed in the hollow area on the light-guiding inner shell 42, which restricts the rotational movement of the light-shielding ring 43 relative to the light-guiding inner shell 42 and ensures a stable connection between the light-shielding ring 43 and the light-guiding inner shell 42.
[0040] Please see Figure 1 , Figure 2 , Figure 6 and Figure 7 In this embodiment, the heat dissipation body 1 includes multiple heat dissipation fins with gaps between adjacent fins, and one end of the light guide inner shell 42 is placed in the gaps. Placing one end of the light guide inner shell 42 in the gaps restricts the rotational movement of the light guide inner shell 42 relative to the heat dissipation body 1, making the overall structure of the heat sink more stable.
[0041] Please see Figure 2 , Figure 4 , Figure 5 and Figure 8In this embodiment, the fan housing 22 has an annular mounting portion 222, and a limiting protrusion 223 is provided on one side of the annular mounting portion 222. The light guide inner shell 42 is provided with a connecting groove 422, and a limiting groove 423 is provided at the bottom of the connecting groove 422. The cooling fan 2 is placed in the light guide inner shell 42, the annular mounting portion 222 abuts against the bottom wall of the connecting groove 422, and the limiting protrusion 223 is placed in the limiting groove 423. The mounting base 221 is provided with a first through hole 2211, and the heat dissipation body 1 is provided with a threaded hole on one side opposite to the cooling fan 2. The cooling fan 2 is threadedly connected to the heat dissipation body 1 by screws. When assembling the heat sink, the cooling fan 2 is placed in the light guide inner shell 42. At this time, the annular mounting part 222 of the fan shell 22 abuts against the bottom wall of the connecting groove 422, and the limiting protrusion 223 is aligned and embedded in the limiting groove 423, thereby restricting the relative rotation between the light guide inner shell 42 and the cooling fan 2. The annular mounting part 222 on the fan shell 22 tightly abuts against the bottom of the connecting groove 422. The screw passes through the first through hole 2211 on the mounting base 221 and is screwed into the threaded hole on the heat sink body 1, thereby firmly connecting the light guide inner shell 42, the cooling fan 2, and the heat sink body 1. Through the cooperation of the limiting protrusion 223 and the limiting groove 423, the cooling fan 2 and the light guide inner shell 42 are accurately positioned and firmly connected. At the same time, the threaded connection between the cooling fan 2 and the heat sink body 1 ensures the tightness of the connection, enabling the cooling fan 2 to operate stably and facilitating the replacement, disassembly, and maintenance of the cooling fan 2 in the future.
[0042] Please see Figure 5 In this embodiment, the cooling fan 2 further includes a connector 224, one end of which is connected to the fan housing 22, and the other end is connected to the mounting base 221. The mounting base 221 has a first through hole 2211, and the heat dissipation body 1 has a threaded hole on one side opposite to the cooling fan 2. The cooling fan 2 is threadedly connected to the heat dissipation body 1 by screws. Optionally, there are four connectors 224, one end of which is evenly connected to the mounting base 221, providing rigid support to the mounting base 221. At the same time, when the mounting base 221 is under pressure, the load on the mounting base 221 can be evenly distributed to ensure the stability of the mounting base 221. There are also four first through holes 2211 on the mounting base 221. The cooling fan 2 and the heat dissipation body 1 are firmly connected by screws passing through the first through holes 2211. The threaded connection method is not only simple and convenient, but also highly versatile and the connection is more secure.
[0043] Please see Figure 2 and Figure 4In this embodiment, the light guide inner shell 42 is further provided with an annular mounting groove 424, which is located below the connecting groove 422. The light-emitting element 41 is housed in the annular mounting groove 424. When the annular mounting portion 222 of the cooling fan 2 abuts against the bottom wall of the connecting groove 422, the light-emitting element 41 is precisely housed in the annular mounting groove 424, ensuring that it can continue to work stably even when the light-emitting element 41 falls off the outer surface of the fan housing 22 later.
[0044] Please see Figure 2 and Figure 6 In this embodiment, the outer surface of the heat dissipation body 1 is provided with multiple slots 11 arranged in a ring. The light guide shell 44 is engaged with the heat dissipation body 1. Each slot 11 is a notch in the heat dissipation fins, with two opposing sidewalls. The length of the sidewall closer to the cooling fan 2 is shorter than the length of the other sidewall. The bottom edge of the light guide shell 44 is engaged within the slot 11, ensuring that the bottom edge of the light guide shell 44 will not disengage from the slot 11 when pressure is applied. The slots 11 effectively prevent the light guide shell 44 from loosening or shifting during use, ensuring the stability of the optical components during heat dissipation operation and guaranteeing the normal presentation of the lighting effect.
[0045] Please see Figure 1 , Figure 2 and Figure 6In this embodiment, the heat sink further includes a base plate bracket 5. The base plate bracket 5 has threaded posts 51. The bottom of the heat sink body 1 has a connecting base 12. The connecting base 12 has an extension section with a second through hole 121. Bolts pass through the second through hole 121 to thread the heat sink body 1 to the base plate bracket 5. The base plate bracket 5 is used to fix the heat sink to the computer motherboard. The threaded posts 51 on the base plate bracket 5 are columnar structures with internal threads for engagement with bolts, thus connecting and fixing the heat sink body 1 to the base plate bracket 5. There are multiple threaded posts 51 on the base plate bracket 5; optionally, there are four. The second through holes 121 on the connecting base 12 are aligned with the threaded posts 51, and the number of second through holes 121 is the same as the number of threaded posts 51. Bolts pass through the second through holes 121 and are screwed into the threaded posts 51 to connect the heat sink body 1 to the base plate bracket 5. Specifically, the base plate bracket 5 is first installed in the corresponding position on the computer motherboard. Then, the second through hole 121 on the connecting base 12 of the heat sink 1 is aligned with the threaded post 51 of the base plate bracket 5. A bolt is passed through the second through hole 121 and tightened onto the threaded post 51. Through the threaded connection between the bolt and the threaded post 51, the heat sink 1 is securely installed on the base plate bracket 5, thus achieving a reliable connection between the heat sink and the computer motherboard. The installation method of the base plate bracket 5 and the connecting base 12 with bolts ensures that the heat sink is firmly installed on the computer motherboard, effectively preventing the heat sink from shaking or shifting during computer operation and ensuring the stability of the heat dissipation effect. At the same time, the threaded connection installation structure has strong versatility and is suitable for various types of computer motherboards, facilitating the promotion and use of the product.
