[0002] In today's technological landscape, many electronic products generate significant amounts of heat during operation. Failure to dissipate this heat promptly can severely impact product performance, lifespan, and stability. For example, LED lamps are increasingly being used in lighting, display, and other fields as LED technology continues to advance. However, these devices generate significant amounts of heat during operation. If this heat is not effectively dissipated, it can lead to elevated junction temperatures.

[0003] When the junction temperature of LED lamp beads rises, a series of problems arise. First, their luminous efficiency decreases significantly, which means that energy utilization efficiency is reduced, not only affecting the lighting or display effect, but also increasing energy consumption. Second, excessively high temperatures accelerate the aging of LED lamp beads, shortening their service life, increasing product replacement frequency and operating costs. In addition, uneven temperature distribution may cause color deviation of LED lamp beads, affecting product quality and consistency.

[0004] Traditional heat dissipation methods often have numerous limitations. For example, while simple heat sink structures can conduct heat to a certain extent, their limited heat dissipation area makes them inadequate for high-heat-generating situations. Conventional air-cooling devices can also suffer from issues such as poor duct design and poor coordination between the fan and heat dissipation components, leading to poor air flow and suboptimal heat dissipation.

[0005] Therefore, it is necessary to propose an improved technical solution to solve the above problems. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1-4 In an embodiment of the present invention, a heat dissipation device for improving the cooling effect of a product includes an air duct fixing plate 1, a fan fixing plate 2, a four-channel air transmission pipe 3 and a cooling fan 4;

[0029] A number of assembly positions 5 arranged in an array at intervals are provided on the upper end surface of the air duct fixing plate 1, and a four-channel air transmission pipe fitting 3 is installed on the assembly position 5. The four-channel air transmission pipe fitting 3 has a four-channel tube 6 extending downward, and the four-channel tube 6 passes through the air duct fixing plate 1 and extends along the lower end surface of the air duct fixing plate 1. A fan fixing plate 2 is installed on the upper end surface of the air duct fixing plate 1 and above the number of assembly positions 5. A number of mounting legs 7 extend from the lower end of the fan fixing plate 2, and a number of the mounting legs 7 are fixedly connected to the fan fixing plate 2, and a number of the mounting legs 7 are located between the intervals of a number of assembly positions 5, wherein a number of cooling fans 4 are installed on the fan fixing plate 2, and a number of the cooling fans 4 are connected one by one with a number of four-channel air transmission pipe fittings 3.

[0030] In the technical solution of the present utility model, assembly positions 5 arranged in an array at intervals are provided on the air duct fixing plate 1 for installing four-channel air transfer pipe fittings 3. This array layout can make the heat more evenly distributed to each four-channel air transfer pipe fitting 3, thereby improving the uniformity of heat dissipation. The four-channel tubes 6 of the four-channel air transfer pipe fitting 3 extend downward through the air duct fixing plate 1, thereby increasing the contact area between the air and the heat dissipation component and the heat exchange path. Heat is transferred through multiple channels, which can more efficiently guide the heat generated by the product to the cooling link. Each four-channel air transfer pipe fitting 3 can independently collect and transfer heat in a certain area. When multiple four-channel air transfer pipe fittings 3 work together, they can cover a larger heat dissipation area.

[0031] The cooling fans 4 are connected to the four-channel air transmission pipes 3 one by one, ensuring that the cooling air can be accurately blown to the four-channel air transmission pipes 3, forming a targeted airflow and accelerating the dissipation of heat. The mounting legs 7 of the fan fixing plate 2 are located between the intervals of the assembly positions 5. This design not only ensures the stable installation of the fan fixing plate 2, but also does not affect the layout and air circulation of the four-channel air transmission pipes 3, making the structure of the entire heat dissipation device more compact and reasonable, and the air flow smoother. Multiple cooling fans 4 can provide stronger wind force to meet the heat dissipation needs of multiple LED lamp beads or large-area LED lamp beads;

[0032] The air duct fixing plate 1 serves as a basic component, providing a stable installation platform for the four-channel air transfer pipe fitting 3, and at the same time plays a role in heat conduction and distribution. The fan fixing plate 2 is used to fix the cooling fan 4 so that it can accurately align the four-channel air transfer pipe fitting 3 to blow air. The four-channel air transfer pipe fitting 3 is responsible for concentrating the heat generated by the product and transferring it to the cooling air, while the cooling fan 4 provides strong wind force to drive the air flow and accelerate the exchange and dissipation of heat. Multiple four-channel air transfer pipe fittings 3 and cooling fans 4 cooperate with each other to achieve comprehensive and efficient heat dissipation of multiple LED lamp beads or large areas of LED lamp beads.

[0033] In summary, the multi-channel design of the four-channel air transfer pipe 3 and the precise docking with the cooling fan 4 greatly improve the heat transfer efficiency, can quickly dissipate the heat generated by the product, effectively reduce the temperature of the product, and avoid problems such as performance degradation and shortened life due to overheating. For products with high heat generation such as LED lamp beads, it can significantly reduce their junction temperature, improve luminous efficiency, reduce energy consumption, and extend service life; the array assembly position 5 layout on the air duct fixing plate 1 allows the heat to be evenly distributed to each four-channel air transfer pipe 3, and then the uniform blowing of the cooling fan 4 achieves uniformity of the entire heat dissipation process. This is especially important for products such as LED lamp beads that require high temperature uniformity. It can avoid quality problems such as color deviation caused by uneven temperature and ensure product consistency and stability. The mounting legs 7 of the fan fixing plate 2 are cleverly located between the assembly positions 5, and the reasonable layout of each component makes the overall structure of the heat dissipation device compact, and realizes efficient heat dissipation function in a limited space, which not only saves installation space, but also facilitates integration and installation in various electronic products. For some electronic devices with limited space, such as small lighting fixtures, compact display screens, etc., this compact design has great advantages.

[0034] In the embodiment of the present invention, the four-channel air transmission pipe 3 includes a hollow shell 8 and the four-channel pipe 6 connected to the shell 8, and an air inlet 9 connected to the air outlet of the cooling fan 4 is opened along the upper end surface of the shell 8.

[0035] The hollow shell 8 of the four-channel air transfer duct 3 is designed to provide a space for accommodating and transmitting air flow. The air blown out by the cooling fan 4 enters the four-channel air transfer duct 3 through the air inlet 9 on the upper end face of the shell 8. The docking design of the air inlet 9 and the air outlet of the cooling fan 4 ensures that the air can smoothly enter the air transfer duct from the fan, reducing air leakage and energy loss. After the air enters the shell 8, it is dispersed to each channel through the four-channel tube 6 connected to the shell 8. This design enables the air to flow in the air transfer duct in an orderly manner, realizing effective guidance and distribution of the air flow; the setting of the four-channel tube 6 increases the contact area between the air and the heat dissipation components. When the air flows in the four-channel tube 6, it can more fully exchange heat with the surface of the product that needs heat dissipation and take away the heat. Each channel can independently absorb and transfer heat in a certain area, thereby improving the efficiency and uniformity of heat dissipation.

[0036] In an embodiment of the present invention, the air duct fixing plate 1 is provided with a plurality of through-holes 10 which penetrate through the plate to allow the four-channel tube 6 to pass through and extend out, wherein sealing rubber rings 11 are embedded in a plurality of the through-holes 10, and the peripheral side of the four-channel tube 6 elastically abuts against the inner side of the sealing rubber ring 11.

[0037] The air duct fixing plate 1 is provided with a through-hole 10 which passes through it, and its main purpose is to provide a passage for the four-channel tube 6 to pass through, so that the four-channel tube 6 can smoothly extend from the upper end face of the air duct fixing plate 1 to the lower end face, thereby realizing the overall structural layout of the heat dissipation device. A sealing rubber ring 11 is embedded in the through-hole 10. By utilizing the elastic characteristics of the sealing rubber ring 11, when the four-channel tube 6 is passed through and extended, the peripheral side of the four-channel tube 6 forms an elastic abutment with the inner side of the sealing rubber ring 11. This abutment mode enables the sealing rubber ring 11 to fit tightly around the four-channel tube 6, forming an effective sealing structure; the elasticity of the sealing rubber ring 11 can adapt to the dimensional changes of the four-channel tube 6 and the slight displacement during the installation process, ensuring that a good sealing effect can be maintained under different working conditions. At the same time, the material selection of the sealing rubber ring 11 is generally wear-resistant and corrosion-resistant to ensure that it will not be damaged by friction with the four-channel tube 6 or environmental factors during long-term use, thereby maintaining its sealing performance;

[0038] During the operation of the heat dissipation equipment, air needs to enter the four-channel air transfer pipe 3 through the cooling fan 4 for heat exchange. If there is a gap at the connection between the air duct fixing plate 1 and the four-channel pipe 6, air may leak, resulting in a reduction in the air volume of the cooling fan 4, affecting the heat dissipation effect. By providing a sealing rubber ring 11, it is possible to effectively prevent air from leaking from the opening 10, ensuring that all cooling air can enter the four-channel air transfer pipe 3, thereby improving air utilization efficiency and enhancing heat dissipation performance.

[0039] In the embodiment of the present invention, the four-channel air transmission pipe 3 is inserted into the assembly position 5 , wherein the connection end of the shell 8 and the four-channel pipe 6 forms an abutment end 12 acting on the through opening 10 .

[0040] The design of the four-channel air transmission pipe 3 being inserted into the assembly position 5 provides the four-channel air transmission pipe 3 with a clear installation position on the air duct fixing plate 1. The assembly position 5 plays a role in positioning and guiding, ensuring that the four-channel air transmission pipe 3 can be accurately installed in the predetermined position and achieve good docking and coordinated work with other components (such as the cooling fan 4). This precise positioning helps to improve the assembly efficiency and accuracy of the entire heat dissipation equipment and reduce installation errors; the connecting end of the shell 8 and the four-channel tube 6 forms an abutting end 12 that acts on the through-port 10. When the four-channel air transmission pipe 3 is installed in place, the abutting end 12 interacts with the through-port 10. This abutting relationship can further ensure the installation stability of the four-channel air transmission pipe 3 on the one hand, and prevent it from being installed during operation. On the other hand, the close contact between the abutting end 12 and the through-port 10 may also assist the sealing rubber ring 11 in achieving a better sealing effect to a certain extent, reducing the possibility of air leakage and impurities entering; the abutting end 12 formed by the connecting end of the shell 8 and the four-channel tube 6 can disperse the external force exerted on the four-channel air transmission pipe 3 (such as the pressure generated by the air flow, the vibration during the operation of the equipment, etc.) to the air duct fixing plate 1 when it acts on the through-port 10. In this way, the stress concentration of the four-channel air transmission pipe 3 itself is reduced, and its structural strength and stability are improved. At the same time, the air duct fixing plate 1 also provides a certain supporting force for the four-channel air transmission pipe 3, making the structure of the entire heat dissipation equipment more stable and reliable.

[0041] In the embodiment of the present invention, the housing 8 includes an upper shell 13 and a lower shell 14 , and the four-channel tube 6 and the lower shell 14 are an integral structure, wherein the upper shell 13 and the lower shell 14 are integrated by ultrasonic welding.

[0042] The modular structural design allows the upper shell 13 and the lower shell 14 to be processed on different production lines or simultaneously, thereby improving production efficiency. The integrated structure of the four-channel tube 6 and the lower shell 14 reduces the assembly process and possible errors, further improving the production speed and the stability of product quality. Ultrasonic welding technology is fast and highly automated, and can complete the welding of the upper shell 13 and the lower shell 14 in a short time, greatly shortening the production cycle.

[0043] In an embodiment of the present utility model, the fan fixing plate 2 includes a main board 19 and the connected mounting legs 7, the main board 19 is provided with a first connecting hole 15, the cooling fan 4 has a threaded hole 16 that cooperates with the first connecting hole 15, and the main board 19 is located between the intervals of several mounting legs 7 thereof and is provided with a makeshift opening 17 that cooperates with the four-channel air transmission pipe 3.

[0044] A first connecting hole 15 is provided on the main board 19 of the fan fixing plate 2, which cooperates with the threaded hole 16 on the cooling fan 4. This design adopts a common and reliable threaded connection method. The cooling fan 4 can be firmly mounted on the fan fixing plate 2 by means of connecting parts such as bolts. The position and size of the first connecting hole 15 are precisely designed according to the threaded hole 16 of the cooling fan 4 to ensure that the two can be accurately connected to achieve a stable connection. This connection method can withstand the vibration and stress generated by the cooling fan 4 during operation, and is easy to install and disassemble, facilitating subsequent maintenance and replacement work.

[0045] The mounting legs 7 are connected to the main board 19, providing a support and fixing structure for the fan fixing plate 2. The design of the mounting legs 7, on the one hand, must take into account the connection strength with the main board 19 to ensure that they will not break or loosen when bearing the weight of the cooling fan 4 and other components and various forces during operation. On the other hand, the position and layout of the mounting legs 7 are reasonably arranged according to the assembly position 5 on the air duct fixing plate 1 and the position of the four-channel air transmission pipe 3. The mounting legs 7 are located between several intervals of the main board 19. Such a design enables the fan fixing plate 2 to avoid the four-channel air transmission pipe 3 when being installed on the air duct fixing plate 1, while providing stable support for the cooling fan 4, thereby achieving reasonable use of space and optimization of structure.

[0046] The main board 19 is provided with clearance openings 17 between its several mounting legs 7. The shape and size of the clearance openings 17 are designed to match the four-channel air transfer duct 3. When the fan mounting plate 2 is mounted above the air duct mounting plate 1, the clearance openings 17 allow the four-channel air transfer duct 3 to pass through, allowing the cooling fan 4 to accurately dock with the four-channel air transfer duct 3. This design avoids interference between the fan mounting plate 2 and the four-channel air transfer duct 3, ensuring that air can smoothly enter the four-channel air transfer duct 3 from the cooling fan 4, achieving efficient heat exchange and heat dissipation. At the same time, the presence of the clearance openings 17 also makes the structure of the fan mounting plate 2 more compact, more closely cooperating with other components, and improving the integration of the entire heat dissipation device.

[0047] In the embodiment of the present invention, second connection holes 18 for connecting with peripheral devices are provided on both sides of the air duct fixing plate 1 .

[0048] Second connection holes 18 are set on both sides of the air duct fixing plate 1. The purpose is to realize the connection between the heat dissipation device and the peripheral device (such as the host and casing of the electronic product that requires heat dissipation). The size and spacing of the second connection holes 18 are usually designed according to industry standards or common connection specifications to ensure that it can be compatible with most peripheral devices. By passing bolts, screws and other connecting parts through the second connection holes 18, the air duct fixing plate 1 can be firmly fixed to the peripheral device, thereby realizing the integrated installation of the heat dissipation device and the peripheral device.

[0049] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
