Description

Technical Field

[0001] This utility model is a composite heat sink structure with profile inserts. Background Technology

[0002] With the continuous increase in power density of electronic devices, the heat generated during system operation is rapidly increasing. As a key thermal management component, the performance of the heat sink directly affects the stability and lifespan of the electronic system. Among the many types of heat sinks, finned heat sinks are widely used in power electronics, computers, high-brightness LED lighting, and other fields due to their simple structure, low cost, and large heat dissipation area.

[0003] In existing technologies, traditional finned heat sinks mostly employ aluminum extrusion or die-casting processes, relying on natural or forced convection for heat exchange. However, due to the limited thermal conductivity of aluminum, heat exchange solely between the fins and air is insufficient to meet the demands of rapid heat dissipation under high heat flux density conditions, easily leading to heat buildup and affecting system performance. Furthermore, simply increasing the number or thickness of fins to improve heat dissipation not only wastes material but may also result in side effects such as restricted airflow channels and reduced heat exchange efficiency.

[0004] To address the aforementioned issues, the industry has gradually introduced various methods to enhance heat dissipation, such as incorporating high thermal conductivity materials into the fin structure and using composite heat exchange channel designs to improve the efficiency of heat conduction and diffusion from the heat source to the air. However, there is still a lack of a composite radiator structure that is simple in structure, reliable in assembly, highly efficient in thermal conductivity, and easy to industrialize. In particular, there is still room for further technological breakthroughs in how to effectively improve the overall heat dissipation performance of the fin structure. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a composite heat sink structure with profile inserts.

[0006] A composite heat sink structure with profile inserts includes a base with multiple heat dissipation fins on the base. The lower end face of the base has a slot, and a heat dissipation copper pipe is installed in the slot.

[0007] Furthermore, the heat dissipation copper pipe is interference-fitted with the slot.

[0008] Furthermore, the base is a detachable structure, comprising an upper base and a lower base, wherein the upper end face of the lower base is detachably connected to the upper end face of the lower base, and a slot is formed on the lower end face of the lower base.

[0009] Furthermore, the upper seat has a first positioning post on its left end face and a first positioning plate on its right end face, with a first positioning hole on the first positioning plate. The lower seat has a second positioning plate on its left end face, with a second positioning hole on the second positioning plate and a second positioning post on its right end face. When the upper and lower seats are assembled, the first positioning post passes through the second positioning hole, and the second positioning post passes through the first positioning hole.

[0010] Furthermore, the outer walls of the first and second positioning pins are provided with threads, and the first positioning pin and the second positioning hole are fitted together and locked by a nut.

[0011] Furthermore, the upper end face of the lower seat is provided with a slider, the upper end face of the slider is provided with a baffle, the edges of the baffle extend out of the edge of the slider, the lower end face of the upper seat is provided with a slide groove, one end of the slide groove is provided with a clearance hole for limiting the baffle, and the inner side wall of the slide groove is provided with a clearance groove for limiting the baffle.

[0012] Furthermore, the fins are fixedly arranged on the base in parallel intervals, and heat sinks are added between some adjacent fins, with the length of the heat sinks being less than or equal to the length of the fins.

[0013] Furthermore, the heat sinks are arranged in a concentrated manner to form a continuous area, and the heat dissipation copper pipes are installed at positions corresponding to the concentrated arrangement area of ​​the heat sinks.

[0014] Beneficial effects: Compared with the prior art, the present invention has the following advantages: This heatsink boasts excellent thermal conductivity, employing a base and cooling fins design. The fins significantly increase the heat exchange area, enhancing air convection and dramatically improving heat dissipation efficiency. Furthermore, copper heat pipes are embedded in slots at the bottom of the base. Thanks to their high thermal conductivity, these copper pipes quickly dissipate heat from the heat source area, further enhancing overall heat dissipation performance.

[0015] The reliability of the structure has also been significantly enhanced. The copper tube is securely embedded in the slot through an interference fit, which not only improves the quality of thermal contact but also effectively prevents loosening caused by vibration or thermal expansion and contraction. In the detachable structure, the positioning pin, positioning hole, and nut locking mechanism work together to ensure a tight connection between the upper and lower seats, providing excellent impact resistance and assembly stability.

[0016] During assembly, the structure boasts high positioning accuracy and ease of assembly.

[0020] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0021] A composite heat sink structure with profile inserts includes a base 2, on which a plurality of fins 1 for heat dissipation are provided. A slot 15 is opened on the lower end face of the base 2, and a heat dissipation copper pipe is provided in the slot 15.

[0022] This heat sink structure is built based on the composite heat transfer principle of profile inserts and copper pipes. The base 2, as the main heat conduction structure, increases the heat exchange area and improves heat dissipation efficiency through multiple heat dissipation fins 1 arranged on its upper surface. Meanwhile, heat dissipation copper pipes are embedded in slots 15 on the lower end face of the base 2. These copper pipes have high thermal conductivity, enabling them to quickly conduct heat from the base 2 to a wider space or into an external heat dissipation system, thereby accelerating the overall heat dissipation process. The profile insert processing method ensures a tight bond between the fins 1 and the base 2, improving the overall thermal conductivity and strength of the structure and ensuring rapid heat dissipation from the heat source area.

[0023] This heat sink structure features slots 15 on the lower surface of the base 2, into which copper heat pipes are embedded. This allows the copper pipes to make direct thermal contact with the base 2, significantly improving heat conduction efficiency and effectively alleviating heat buildup issues during electronic device operation. The fins 1 further increase the heat dissipation area, enhancing overall heat dissipation performance while maintaining a compact structure. Simultaneously, the profile insert structure facilitates mass production, ensuring component assembly precision and thermal performance consistency, thereby improving product reliability and lifespan.

[0024] In one possible implementation, the heat dissipation copper pipe is interference-fitted with the slot 15.

[0025] This structure achieves a tight bond by interfering with the heat dissipation copper pipe and the pre-set slot 15 in the base 2, utilizing the elastic deformation of the material. This fit allows the copper pipe to be firmly embedded in the slot 15 during installation, eliminating the need for additional fixing structures, thereby reducing thermal resistance and enhancing the heat conduction efficiency between the copper pipe and the base 2. During heat transfer, the copper pipe absorbs heat from the base 2 and quickly dissipates the heat energy through its excellent thermal conductivity.

[0026] The interference fit effectively increases the thermal contact area between the copper tube and the base 2, reduces thermal resistance, and enhances heat dissipation. It also improves assembly strength and structural stability, preventing the copper tube from loosening or detaching during use. Furthermore, the elimination of additional fixing mechanisms simplifies structural design and manufacturing processes, reducing production costs.

[0027] In one possible implementation, the base 2 is a detachable structure, which includes an upper base 3 and a lower base 4. The upper end face of the lower base 4 is detachably connected to the upper end face of the lower base 4, and the slot 15 is formed on the lower end face of the lower base 4.

[0028] By designing the base 2 as a detachable upper seat 3 and lower seat 4 structure, maintenance and replacement of the slot 15 and heat dissipation copper pipe are facilitated. The slot 15 is located on the lower end face of the lower seat 4, allowing the copper pipe to be installed closer to the heat source. The upper seat 3 and lower seat 4 can be connected by screws, clips, etc., making assembly and disassembly simple and quick. This structural design fully considers the convenience of later product maintenance.

[0029] The detachable structure significantly improves the maintainability and replaceability of the equipment. When the heat dissipation copper pipe is damaged or fails, the lower seat 4 can be easily removed for replacement without replacing the entire heat sink module, effectively saving maintenance costs. It also facilitates cleaning and troubleshooting of the cause of decreased heat transfer efficiency, improving the efficiency of product lifecycle management.

[0030] In one possible implementation, the upper seat 3 has a first positioning post 5 on its left end face and a first positioning plate 7 on its right end face, with a first positioning hole on the first positioning plate 7. The lower seat 4 has a second positioning plate 8 on its left end face, with a second positioning hole on the second positioning plate 8 and a second positioning post 6 on its right end face. When the upper seat 3 and the lower seat 4 are assembled, the first positioning post 5 passes through the second positioning hole, and the second positioning post 6 passes through the first positioning hole.

[0031] This structure uses interlocking positioning posts and holes on both sides of the upper and lower seats 4 to form a mating positioning relationship, thereby ensuring precise alignment and stable connection between the upper seat 3 and the lower seat 4 during assembly. The bidirectional positioning design improves assembly consistency and reduces installation deviations caused by errors. The positional settings of the positioning holes and posts ensure stable constraint of the overall structure in both the lateral and longitudinal directions, preventing component misalignment.

[0032] This structure can significantly improve the positioning accuracy during the assembly process of the upper and lower seats, prevent the heat conduction path from deviating and affecting the heat dissipation efficiency; improve the consistency of product assembly and structural stability, reduce performance loss and rework rate caused by component mismatch; and enhance the overall structure's seismic resistance and anti-detachment performance.

[0033] In one possible implementation, the outer walls of the first positioning post 5 and the second positioning post 6 are provided with threads, the first positioning post 5 and the second positioning hole, and the second positioning post 6 and the first positioning hole are engaged and locked by a nut.

[0034] This embodiment, based on the original positioning post, adds threads to the outer wall of the positioning post and locks them in place with a nut, making the connection between the upper seat 3 and the lower seat 4 more secure and reliable. During assembly, after the threaded post passes through the corresponding positioning hole, tightening the nut creates an axial clamping force, further enhancing the tensile strength and vibration resistance of the connection structure.

[0035] The threaded locking mechanism not only improves the reliability and strength of the connection structure, but also facilitates disassembly and maintenance, reducing the difficulty of troubleshooting. Threaded connections have good anti-loosening properties, are suitable for high-temperature and vibration environments, and improve the overall stability and safety of the product.

[0036] In one possible implementation, the upper end face of the lower seat 4 is provided with a slider 10, the upper end face of the slider 10 is provided with a baffle 9, the edges of the baffle 9 extend out of the edge of the slider 10, the lower end face of the upper seat 3 is provided with a sliding groove 11, one end of the sliding groove 11 is provided with a clearance hole 13 for limiting the baffle 9, and the inner side wall of the sliding groove 11 is provided with a clearance groove 12 for limiting the baffle 9.

[0037] This structure uses a slider 10 and a slide groove 11 to guide the connection between the upper and lower seats 4. A baffle 9 is provided on the slider 10, extending outwards. During assembly, it is guided into place via the slide groove 11. The edge of the baffle 9 spatially matches and limits the movement of the slide groove 12 and the clearance hole 13 within the slide groove 11. This structure effectively guides the alignment of the upper and lower seats 4 and achieves limiting and stopping functions through a mechanical structure, improving the accuracy and stability of the assembly.

[0038] The guiding structure of slider 10 and slide groove 11 can simplify the assembly process and improve positioning efficiency. The baffle 9 structure can play a stopping function to prevent the upper and lower seats 4 from falling off, enhancing the overall safety and error prevention capability of the structure. At the same time, the design of the clearance hole 13 and clearance groove 12 helps to limit the movement of baffle 9, improve the connection reliability and the stability of the heat conduction structure.

[0039] In one possible implementation, the fins are fixedly arranged in parallel at intervals on the base, and heat sinks 14 are added between some adjacent fins. The length of the heat sink 14 is less than or equal to the length of the fin. The heat sinks are arranged in a concentrated manner to form a continuous area, and the heat dissipation copper pipe is set at the position corresponding to the concentrated arrangement area of ​​the heat sinks.

[0040] Multiple fins are fixed to the base at intervals. To improve overall heat dissipation performance, auxiliary heat sinks are not added between all adjacent fins, but only between some adjacent fins. This "partial addition" structural design is based on a comprehensive consideration of various thermal engineering and structural optimization principles, and has clear technical effects and rationality.

[0041] First, the heat source is usually not evenly distributed on the base. In practical applications, some areas generate concentrated heat due to supporting high-power chips or power devices. By adding auxiliary heat sinks between adjacent fins in these "hot spots," the local heat exchange efficiency can be significantly improved. For areas with less heat flow, there is no need to configure additional heat sinks, thus avoiding material waste and improving the overall thermal utilization rate of the system.

[0042] Secondly, the airflow path is a crucial factor affecting heat dissipation efficiency. If auxiliary heat sinks are placed between all the fins, the airflow channels will narrow, especially in natural convection or low-speed air-cooled environments, easily leading to airflow blockage and impacting cooling efficiency. By adding heat sinks only between some fins, sufficient airflow channels can be maintained while ensuring heat dissipation capacity, promoting smooth airflow through the fin area and thus enhancing convective cooling.

[0043] Furthermore, from a structural manufacturing perspective, a fully distributed heatsink design increases processing difficulty and assembly costs. A partial configuration, on the other hand, simplifies the assembly process, reduces manufacturing costs, and makes this structure more feasible and economical for mass production.

[0044] Finally, the placement of auxiliary heat sinks in certain locations can also regulate the heat dissipation path. By rationally arranging the heat sinks, heat from hot spots can dissipate outwards through multiple paths, achieving thermal equilibrium, effectively reducing localized temperature rise, and improving equipment stability.

[0045] In summary, by adding auxiliary heat sinks between some adjacent fins, this invention balances heat dissipation efficiency, airflow, structural compactness, and manufacturing economy, demonstrating comprehensive performance advantages over traditional full-coverage heat sink designs.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
