Description

Technical Field

[0001] This utility model relates to the field of equipment heat dissipation technology, and in particular to a CPU heat dissipation device with a flow-guiding fan. Background Technology

[0002] The central processing unit (CPU) is the core computing unit of electronic devices, responsible for executing instructions and processing data. It integrates billions of transistors and achieves high-speed computing through miniaturization technology. Continuous operation generates a lot of heat. Excessive temperature will cause performance degradation or even hardware damage. To ensure its stable operation, CPU cooling devices have emerged. These devices use heat-conducting media and airflow to quickly transfer heat from the chip and maintain the CPU within a safe temperature range.

[0003] Traditional CPU cooling devices operate based on the principles of heat conduction and forced convection. Their core components consist of a metal base, heat pipes, cooling fins, and a fan. Heat is transferred from the CPU surface to the heat pipes via the base, then conducted to the fin array through the phase change of the internal working fluid, and finally dissipated into the air by the fan-driven airflow. This structure has significant defects: the heat pipe direct-contact base is prone to deformation under long-term pressure, leading to increased thermal resistance at the contact surface; the excessively dense spacing of the cooling fins easily accumulates dust, forming a heat insulation layer; and the disordered airflow distribution causes a decrease in heat dissipation efficiency in the edge areas.

[0004] Existing airflow-guided fan cooling devices employ aerodynamic optimization designs, using radial blades of a centrifugal blower to guide airflow directionally through the core area of ​​the fins. For example, airflow-guided rings combined with arc-shaped grilles enhance airflow concentration. While this structure improves heat dissipation uniformity, the heat dissipation fins are fixed by integral welding, and the airflow-guided components are rigidly connected to the main body via complex clips. However, in practical use, the lack of a detachable structure for the heat dissipation fins necessitates complete disassembly for cleaning and maintenance, posing a risk of damage to the airflow-guided fins. Therefore, a CPU cooling device with an airflow-guided fan is proposed to solve the above problems. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a CPU cooling device with a heatsink fan, comprising a base 1, with multiple heat pipes 13 fixedly connected to the outer wall of the base 1. The base 1 is in close contact with the CPU surface, efficiently conducting heat to the cooling module to ensure stable processor operation. Multiple heat dissipation fins 11 are fixedly connected to the outer wall of the heat pipes 13. The heat dissipation fins 11 are made of thin aluminum sheets, increasing the surface area to enhance air convection cooling. The heat pipes 13 utilize internal working fluid phase change to quickly transfer heat from the base 1 to the heat dissipation fins 11. A second clamping strip 9 is fixedly connected to one adjacent end of the heat sink 11. The second clamping strip 9 assists in clamping the heat sink 11. A cross groove 10 is formed on the outer wall of the second clamping strip 9. A first clamping strip 24 is fixedly connected to the upper middle end of the outer wall of the heat pipe 13. The first clamping strip 24 is used to prevent the high-density fins from deforming due to vibration and transportation, and to maintain the integrity of the air duct. A circular groove 12 is formed on the outer wall of the first clamping strip 24. A first reinforcing bolt 3 is threadedly connected to the outer wall of the circular groove 12. The circular groove 12 is used to fix the threaded part of the first reinforcing bolt 3. The upper part of the outer wall of the first reinforcing bolt 3 is threaded with a nut 4, which is used to reinforce the first reinforcing bolt 3. The outer wall of the first reinforcing bolt 3 is slidably connected with a rubber pad 7. The elasticity of the rubber pad 7 can absorb mechanical vibration or impact energy, reducing the risk of loosening of the nut 4 due to long-term vibration. The upper part of the first reinforcing bolt 3 is provided with a texture 6. The texture 6 converts the rotational force into axial fastening force through the spiral inclined structure, realizes linear displacement and generates friction self-locking, and ensures that the connection is stably fixed. The middle part of the first reinforcing bolt 3 is fixedly connected with a cross bar 5. The function of the cross bar 5 is to achieve multi-directional force locking by engaging the cross-shaped head with the corresponding groove, enhancing the connection stability and preventing accidental dislodgement. The bottom end of the first reinforcing bolt 3 is fixedly connected with a reinforcing block 8. The function of the reinforcing block 8 is to prevent the heat dissipation fins 11 from falling off from the bottom. Heat dissipation components are provided on the front and rear sides of the outer wall of multiple heat dissipation fins 11. Reinforcing components are provided on the front and rear sides of the outer wall of multiple heat dissipation fins 11. The top of the outer wall of the base 1 is provided with a shock absorption and noise reduction mechanism 2. The shock absorption and noise reduction mechanism 2 is used to eliminate the noise generated by frequent vibration during the operation of the device.

[0035] Specifically, multiple heat pipes 13 are fixedly installed on the outer wall of the base 1. The base 1 is in close contact with the CPU surface to achieve efficient heat conduction, quickly directing the heat generated by the processor to the cooling system to ensure its stable operation. Multiple thin aluminum heat dissipation fins 11 are evenly distributed on the outer wall of the heat pipes 13. Their flat structure design greatly increases the contact area with air, improving heat dissipation efficiency by enhancing natural convection. The heat pipes 13 use the working fluid phase change principle to quickly transfer heat from the base 1 area to the far-end heat dissipation fins 11 in the form of vapor-liquid phase change. A second clamping strip 9 is installed at the adjacent edge of the heat dissipation fins 11. This component implements mechanical structure to support the heat dissipation fins 11. Lateral constraint, the cross groove 10 on its surface optimizes the assembly accuracy of the connectors. The first clamping strip 24, located in the upper section of the heat pipe 13, maintains a rigid connection with the fin assembly. This design effectively prevents the high-density heat dissipation fins 11 from deforming during vibration or transportation, ensuring that the heat dissipation duct maintains a standard shape. The outer wall of the first clamping strip 24 is machined with a circular groove 12, and its internal thread structure forms a precise fit with the first reinforcing bolt 3, constituting a basic fixing node. The upper part of the first reinforcing bolt 3 and the nut 4 form a secondary reinforcement through the thread pair. This double composite connection significantly improves the structural stability. An elastic rubber pad 7 is sleeved around the bolt body, utilizing polymer materials. The deformation characteristics absorb vibration energy during equipment operation, reducing the probability of thread loosening due to continuous mechanical impact. The texture 6 in the middle section of the bolt body adopts a spiral inclined surface design, converting rotational torque into axial clamping force. Through the frictional self-locking effect, the fastener is permanently positioned. The reinforcing block 8 welded to the bottom of the bolt body forms a physical limiting barrier to prevent the heat dissipation fin 11 from displacing or falling off in the vertical direction. The cross bar 5 in the center of the bolt body and the matching groove form a multi-directional interlocking, realizing three-dimensional force locking and eliminating the risk of accidental dislodgement of the connector. Heat dissipation components and reinforcing components are respectively set on the front and rear sides of the heat dissipation fin 11. The former improves heat dissipation by optimizing the airflow path. The latter uses a mesh support structure to enhance the overall frame 15's resistance to deformation. The shock absorption and noise reduction mechanism 2 installed on the top of the base 1 integrates multi-layer damping materials. Through the principle of energy dissipation, it converts the mechanical vibration generated by the equipment operation into heat energy, effectively suppressing the generation of high-frequency noise. The device internally uses a honeycomb sound-absorbing structure and elastic support components to work together to achieve vibration attenuation and sound wave suppression in a wide frequency range. The entire heat dissipation system, through the synergistic effect of five modules—heat pipe 13 directional heat conduction, multi-level mechanical reinforcement, elastic buffering, aerodynamic optimization, and acoustic control—constructs a complete heat dissipation solution with high reliability, long life, and low noise characteristics.

[0036] Reference Figure 2 , Figure 6 and Figure 7The vibration damping and noise reduction mechanism 2 includes a fixed base 201. The bottom of the outer wall of the fixed base 201 is fixedly connected to the top of the outer wall of the base 1. The fixed base 201 serves as a reinforcement and buffer. An inner rod 202 is fixedly connected to the top of the fixed base 201. An outer rod 203 is slidably connected to the outer wall of the inner rod 202. The outer rod 203 acts as a rigid shell to constrain the movement trajectory of the inner rod 202, providing external support and transmitting the overall load, while protecting the internal components from environmental damage. A first spring 204 is fixedly connected to the top of the inner wall of the outer rod 203. The inner rod 202 directly absorbs dynamic stress through elastic deformation, driving the first spring. The 204 function and the guide structure maintain the accuracy of axial movement to avoid off-center load failure. The first spring 204 absorbs impact or vibration energy through deformation and releases energy when it recovers its deformation, realizing the buffering and balance of dynamic load. The inner wall of the outer rod 203 is fixedly connected to the sealing gasket 206. The sealing gasket 206 ensures smooth operation of the component and reduces wear by isolating external contaminants and preventing internal lubricant leakage. At the same time, it maintains system pressure and cleanliness to extend the overall life. The top of the outer rod 203 is fixedly connected to the embedding block 205, which is used to fix the outer rod 203 and the second clamping bar 9.

[0037] Specifically, the vibration damping and noise reduction mechanism 2 is composed of multiple precision components. Its core function is to achieve system stability through mechanical transmission and energy conversion. The fixed base 201 serves as the basic support unit, with its bottom outer wall rigidly connected to the top outer wall of the base 1, serving the dual purpose of structural reinforcement and stress buffering. The top of the fixed base 201 is fixedly connected to the inner rod 202, and the outer wall of the inner rod 202 and the outer rod 203 form a sliding fit relationship. The outer rod 203, with its high-strength material properties, constrains the movement trajectory of the inner rod 202, thus supporting the external load while evenly distributing the load. The sealed structure effectively isolates dust particles and corrosive media from the environment, ensuring the long-term reliable operation of the internal moving parts. A first spring 204 is mounted on the top of the inner wall of the outer rod 203. This elastic element forms a dynamic linkage mechanism with the inner rod 202. When the inner rod 202 is subjected to alternating loads, it triggers spring deformation through axial displacement, precisely absorbing the kinetic energy generated by mechanical vibration. The guide mechanism inside the spring ensures that the energy conversion process maintains linear motion characteristics, eliminating the risk of component fatigue caused by asymmetric stress. During the compression phase, the first spring 204 converts impact energy into stored elastic potential energy. When the external force weakens, it releases the stored energy through extension, forming a dynamic balance mechanism to stabilize system pressure fluctuations. The sealing gasket 206, circumferentially installed on the inner wall of the outer rod 203, is made of wear-resistant composite material. Its annular structure forms a double protective barrier, preventing external contaminants from entering the moving cavity and effectively locking the internal lubricating medium. By maintaining the integrity of the oil film between the friction pairs, it significantly reduces the rate of mechanical wear. This sealing structure also has a pressure regulation function, ensuring that the system maintains a constant cleanliness and optimal operating parameters. The top of the outer rod 203... The embedded block 205 achieves the positioning connection with the second clamping bar 9. The embedded block 205 adopts a mortise and tenon interface design. While ensuring the connection strength between the outer rod 203 and the clamping bar, it reserves an appropriate amount of deformation space to adapt to the thermal expansion and contraction effect under different working conditions. Through the synergistic effect of multi-level buffering and closed-loop protection, this component forms a systematic solution from energy absorption to load distribution, showing excellent performance in the fields of mechanical vibration suppression and noise control. Its modular design concept takes into account both maintenance convenience and functional expansion potential, providing a reliable guarantee for the long-term operation of equipment under complex working conditions.

[0038] Reference Figure 1 , Figure 2 and Figure 5A light strip 23 is fixedly connected to the top of the first clamping bar 24. The surface of the light strip 23 is made of silicone. The light strip 23 provides decorative lighting through RGB dynamic light effects, enhancing the visual aesthetics of the host and improving the overall assembly style. Locking pieces 14 are fixedly connected to the left and right sides of the base 1. The locking pieces 14 are used to secure the motherboard. The left and right locking pieces 14 are symmetrically distributed. Screws 19 are threaded on the outer wall of the locking pieces 14. The screws 19 use precise torque control to evenly press the base 1 onto the CPU surface, ensuring that the thermal resistance of the contact surface is minimized. A second spring 20 is fixedly connected to the top of the locking pieces 14. The second spring 20 provides elastic preload to compensate for installation tolerances and thermal expansion and contraction deformation, and prevents the screws 19 from loosening due to long-term vibration. A retaining strip 22 is fixedly connected to the top of the first clamping bar 24. The retaining strip 22 is made of thermally conductive material. The retaining strip 22 is used to reinforce the heat pipe 13 and prevent it from falling off. The heat dissipation assembly includes a frame 15. The outer wall of the frame 15 is fixedly connected to the outer wall of the heat dissipation fins 11. The frame 15 is internally fixedly connected to a bracket 16. The frame 15 provides structural support and protective boundaries, fixes the overall components, constrains the airflow path to maintain rotational balance, and guides the airflow direction to ensure safe and low-noise operation. The front side of the outer wall of the bracket 16 is fixedly connected to a swivel joint 17. The front side of the swivel joint 17 is rotatably connected to a fan blade 18. The bracket 16 fixes the fan blade 18 through the rigid frame 15. The swivel joint 17 supports the high-speed rotation of the fan blade 18 with low friction, while simultaneously reducing vibration, noise, and wear, ensuring heat dissipation efficiency and the lifespan of the fan blade 18. The fan blade 18, through its aerodynamic curved surface and tilt angle design, forms a high-pressure, low-turbulence airflow when rotating at high speed, directionally penetrating the gap of the heat dissipation fins 11 to maximize heat exchange efficiency while suppressing noise generation. The reinforcement component includes a second reinforcement bolt 21. The rear side of the outer wall of the second reinforcement bolt 21 is fixedly connected to the front side of the outer wall of the frame 15. The second reinforcement bolt 21 is used to fix the cooling fan and the heat dissipation fins 11. The surface of the second reinforcement bolt 21 is rounded.

[0039] Specifically, the upper end of the first clamping strip 24 is fixedly connected to the light strip 23. The outer layer of the light strip 23 is covered with silicone material, and its built-in dynamic RGB light effect system can generate multi-color gradient light, creating a layered decorative lighting atmosphere inside the host, enhancing the visual hierarchy and technological feel of the overall assembly solution. A set of locking pieces 14 is installed on each of the left and right edges of the base 1. This structure is designed to adapt to motherboards of different specifications. The symmetrically distributed locking pieces 14 enable quick alignment and installation. The outer surface of the locking pieces 14 is machined with precision threads to form an interlocking connection with the screws 19. The screws 19 use precise torque control technology to evenly press the base 1 against the CPU surface, effectively reducing contact. The surface thermal resistance ensures efficient and stable heat conduction path. The top of the locking piece 14 vertically fixes the second spring 20. This elastic element continuously applies pressure through a preset deformation, automatically compensating for dimensional tolerances generated during assembly and simultaneously offsetting metal deformation caused by temperature changes during equipment operation. This fundamentally suppresses the displacement tendency of the screw 19 under high-frequency vibration environment, ensuring structural integrity during long-term use. The top of the first clamping strip 24 extends into a locking strip 22, made of a high thermal conductivity alloy material. It tightly wraps the heat pipe 13 body through a three-point contact mode, forming an anti-detachment protection structure, significantly improving the impact resistance of the heat pipe 13 under complex working conditions. The core of the heat dissipation system consists of frame 1. The main structure consists of frame 15, which forms a fully enclosed connection with the outer edge of the heat sink fins 11. An integrated bracket 16 serves as the load-bearing skeleton. Frame 15 constructs a three-dimensional support system through multi-directional force points, strengthening the overall mechanical strength of the components and precisely guiding the airflow channel. This maintains the dynamic balance of the fan blades 18 while optimizing the airflow trajectory, achieving a synergistic improvement in heat dissipation efficiency and noise reduction. A hinge 17 is mounted at the front end of the bracket 16. This component is dynamically connected to the fan blades 18 via precision bearings. The hinge 17 employs composite lubrication technology to reduce the coefficient of friction, minimizing mechanical vibration and noise levels while supporting the fan blades 18 at thousands of revolutions per minute, thus extending their lifespan. The lifespan of the core moving components is extended by the curved shape of the fan blade 18, which is designed based on fluid dynamics simulation. Each blade is set with a specific tilt angle and curvature, forming a laminar high-pressure airflow when rotating. This airflow flows through the matrix air duct of the heat dissipation fin 11 in a directional penetration mode, which greatly improves the heat exchange efficiency per unit time. At the same time, the air friction sound wave is reduced by eddy current suppression technology. The second reinforcing bolt 21 is embedded in the side wall of the frame 15 as a key connector. Its surface is polished at the nanoscale to eliminate sharp edges. This component adopts a multi-point distributed fixing scheme to integrate the cooling fan module and the heat dissipation fin 11 structure into a rigid whole. The structural stability of the heat dissipation system under high-speed operation is enhanced by the stress dispersion principle.

[0040] Working principle: First, when the CPU cooler equipped with a flow guide fan needs maintenance due to dust accumulation in the gaps between the heat dissipation fins 11 caused by long-term operation, the disassembly and cleaning operation can be performed according to the following procedure: First, use a tool to align with the nut 4 at the top of the first clamping strip 24 and rotate it counterclockwise until the nut 4 is completely disengaged from the first reinforcing bolt 3. At this time, smoothly pull out the first reinforcing bolt 3 from the bottom of the heat dissipation fin 11. Then, unlock the locking strip 22 at the top of the heat pipe 13 to release its fixed state. Continue to slowly move the entire heat pipe 13 from the bottom of the heat dissipation fin 11 in a horizontal straight line. At this point, all mechanical connections of the heat dissipation fin 11 module have been released, and it can be moved out of the main structure of the heat dissipation fin 11. Thoroughly clean the dust deposited in the gaps between the heat dissipation fins 11 and inside the flow guide channel. After cleaning, reassemble the components in reverse order to ensure that the tightening torque of the nut 4 meets the standard value, the locking strip 22 is locked in place without any loosening, and the insertion depth of the heat pipe 13 and the fixing bolt is restored to the initial installation parameters. Finally, the cleaning and maintenance process of the heat dissipation system is completed.

[0041] Furthermore, during the operation of the heat dissipation system, the acoustic interference generated by the fan operation includes not only the aerodynamic noise caused by the rotation of the fan blades 18, but also the resonant noise formed by mechanical vibration transmitted to the equipment housing through the base 1. In order to systematically solve the negative impact of such composite noise on the stability of the equipment and the user experience, a vibration damping and noise reduction mechanism 2 is specially integrated as a vibration isolation solution. The core functional component of this mechanism is the second spring 20, which forms an elastic coupling system between the outer rod 203 and the inner rod 202 through a precision-designed spiral structure. During the operation of the heat sink, the second spring 20 periodically stores and releases elastic potential energy according to the vibration frequency, forming a canceling force opposite to the phase of the original vibration waveform, thereby effectively attenuating the high-frequency micro-amplitude vibration energy transmitted to the base 1. At the same time, the elastic element achieves adaptive matching of damping characteristics through pre-compression adjustment, ensuring that vibration suppression efficiency can be maintained under different speed conditions, ultimately achieving the goal of eliminating the source of mechanical vibration noise and significantly improving the quietness of equipment operation and structural reliability.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
