Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide an aluminum heat sink based on a multi-airflow structure, which improves the heat dissipation efficiency of the heat sink through a three-dimensional airflow design and enhanced heat exchange structure.

[0030] like Figures 1 to 7 The image shows an embodiment of the present invention, relating to an aluminum heat sink based on a multi-channel structure, comprising a heat sink body 10 and a cooling module 20; the heat sink body 10 includes a base 11, a Y-shaped column 12, a first heat dissipation group 13, a second heat dissipation group 14, and a third heat dissipation group 15; the base 11 is used to connect to the workpiece to be cooled; the Y-shaped column 12 is integrally formed with the base 11; the first heat dissipation group 13 and the second heat dissipation group 14 are symmetrically connected to the two side branches of the Y-shaped column 12, and each heat dissipation group includes several horizontally spaced heat dissipation fins 30, with a horizontal air channel 31 formed between adjacent horizontal heat dissipation fins 30; the third heat dissipation group 15 is connected to the top main body of the Y-shaped column 12, and the third heat dissipation group 15 includes several vertical heat dissipation fins 40 perpendicular to the horizontal heat dissipation fins 30, with a vertical air channel 41 formed between adjacent vertical heat dissipation fins 40; the cooling module 20 is provided in two parts, and the two cooling modules 20 are respectively fixedly installed on both sides of the heat sink body 10.

[0031] Specifically, the radiator body 10 divides the heat dissipation area into two branches of horizontal air ducts 31 and a main vertical air duct 41 at the top, forming a three-dimensional heat dissipation network. The horizontal air ducts 31 and the vertical air ducts 41 are perpendicularly intersecting, which can guide air to form convection in both horizontal and vertical directions, avoiding heat dissipation blind spots caused by airflow in one direction and significantly improving the heat exchange efficiency between air and heat sinks. The first heat dissipation group 13 and the second heat dissipation group 14 are symmetrically distributed on both sides of the Y-shaped column 12, ensuring that the heat from the workpiece to be cooled is evenly distributed to the horizontal heat sinks 30 when it is transferred to both sides through the base 11, avoiding local overheating. The Y-shaped column 12 and the base 11 are integrally molded, which reduces the thermal resistance of the connecting parts and improves the continuity of heat conduction. The two cooling modules 20 are respectively installed on both sides of the radiator body 10, which can simultaneously actively cool the air in the horizontal air ducts 31, forming a composite heat dissipation system, which is especially suitable for high power density heat-generating workpieces.

[0032] like Figure 2 and Figure 3 As shown, mounting strips 16 are provided on both sides of the top of the Y-shaped column 12. The mounting strips 16 are connected to the cooling module 20 by screws or adhesive. Specifically, the screw connection ensures a rigid connection between the cooling module 20 and the radiator body 10, avoiding poor contact caused by vibration, and also supports quick disassembly and assembly, facilitating later maintenance and replacement; the adhesive connection can adapt to the fitting requirements of irregularly shaped cooling modules 20, improving structural compatibility.

[0033] like Figure 1 As shown, the cooling module 20 includes an air-cooled component 50 and a water-cooled component 60; the air-cooled component 50 is disposed on one side of the water-cooled component 60; the side of the water-cooled component 60 facing away from the air-cooled component 50 is connected to the radiator body 10. Specifically, the water-cooled component 60 directly contacts the radiator body 10 to absorb high heat, and the core heat is quickly removed by circulating water; the air-cooled component 50 provides auxiliary heat dissipation to the outside of the water-cooled component 60 and the horizontal air duct 31, reducing the surface temperature of the water-cooling pipe 61 and adapting to the heat dissipation requirements under different operating conditions.

[0034] like Figure 4 As shown, the air-cooled assembly 50 includes an outer frame 51, a cooling fan 52, and a protective mesh 53. The outer frame 51 is fixedly connected to one side of the water-cooled assembly 60. The cooling fan 52 is located inside the outer frame 51. The protective mesh 53 is installed on the outside of the outer frame 51. Specifically, the outer frame 51 fixes the water-cooled assembly 60 and provides structural support; the cooling fan 52 forces airflow and accelerates heat exchange within the transverse air duct 31; the outer protective mesh 53 prevents foreign objects from entering and blocking the air duct, while not affecting airflow, thus maintaining heat dissipation efficiency while ensuring safety.

[0035] like Figures 4 to 7As shown, the water-cooling assembly 60 includes water-cooling pipes 61, a top water tank 62, a bottom water tank 63, mounting clips 64, and serpentine heat sinks 65. Multiple sets of water-cooling pipes 61 are provided, with both ends of each set connected to the top water tank 62 and the bottom water tank 63, respectively. The top water tank 62 is located above the bottom water tank 63. The mounting clips 64 connect the top water tank 62 and the bottom water tank 63. The serpentine heat sinks 65 are arranged side-by-side and pass through the multiple sets of water-cooling pipes 61. Specifically, the multiple sets of water-cooling pipes 61 connect the top water tank 62 and the bottom water tank 63, forming a closed water circulation channel. The serpentine heat sinks 65, passing through the water-cooling pipes 61, significantly increase the contact area with air, while forcing the airflow to generate turbulence, disrupting the boundary layer effect, and improving the heat transfer coefficient on the air side. The mounting clips 64 fix the water tanks, ensuring the water-cooling system's airtightness under vibration.

[0036] like Figure 4 As shown, the top water tank 62 is connected to an inlet port 66 and an outlet port 67, both of which are externally connected to water pumps (not shown in the figure). Specifically, by setting water pumps (not shown in the figure) to the inlet port 66 and outlet port 67, the water flow rate can be controlled by adjusting the pump power to adapt to different heat load scenarios. High-speed water flow can quickly remove peak heat, while low-speed water flow can reduce energy consumption, achieving a balance between heat dissipation efficiency and power consumption.

[0037] like Figure 6 As shown, a heat dissipation gap 68 is formed between adjacent layers of the water-cooling pipe 61, and the serpentine heat sink 65 extends along the heat dissipation gap 68. Specifically, the heat dissipation gap 68 between adjacent layers of the water-cooling pipe 61 provides installation space for the serpentine heat sink 65. The serpentine heat sink 65 extends along the gap, closely adhering to the surface of the water-cooling pipe 61, reducing thermal resistance, and simultaneously conducting the heat of the water-cooling pipe 61 to the air side, forming multiple heat transfer paths.

[0038] like Figure 7 As shown, there are two mounting clips 64, which are respectively connected to the mounting strip 16 and the base 11. Specifically, the two mounting clips 64 are respectively connected to the mounting strip 16 and the base 11 to form a two-point fixing structure, which prevents the cooling module 20 from shifting due to vibration during long-term operation, ensures a tight fit between the water cooling component 60 and the heat sink body 10, and maintains efficient heat conduction performance.

[0039] like Figure 3As shown, the horizontal heat sink 30 has wavy first grooves 32 on both sides of its edge, and the first grooves 32 are continuously distributed along the extension direction of the horizontal heat sink 30; the vertical heat sink 40 has wavy second grooves 42 on both sides of its edge, and the second grooves 42 are continuously distributed along the extension direction of the vertical heat sink 40. Specifically, the first grooves 32 of the horizontal heat sink 30 and the second grooves 42 of the vertical heat sink 40 are continuously distributed along the extension direction. The wavy structure breaks the laminar flow state of the airflow, increases the contact time between the air and the surface of the heat sink, and at the same time, the concave and convex surfaces of the grooves form additional heat dissipation areas, effectively expanding the heat dissipation area, and significantly improving the heat dissipation effect, especially in low wind speed environments.

[0040] The working principle of this utility model is as follows:

[0041] The heat from the workpiece to be cooled is transferred to the Y-shaped column 12 through the base 11. Utilizing the high thermal conductivity of the one-piece molded structure, the heat is quickly and evenly distributed to the first heat dissipation group 13, the second heat dissipation group 14 on both sides, and the third heat dissipation group 15 at the top. The horizontal heat dissipation fins 30 and the vertical heat dissipation fins 40 exchange heat with the outside air through the horizontal air duct 31 and the vertical air duct 41, respectively.

[0042] The top water tank 62 receives low-temperature cooling water through the inlet port 66. After absorbing heat from the heat sink and Y-shaped column 12 through multiple sets of water-cooling pipes 61, the heated water flows into the bottom water tank 63 and is circulated through the outlet port 67 to external cooling devices such as the condenser via a water pump (not shown in the figure). The serpentine heat sink 65 is installed between the water-cooling pipes 61, simultaneously absorbing heat from the surface of the water-cooling pipes 61 and releasing it into the air. The cooling fan 52 forces airflow through the transverse air duct 31, cooling the transverse heat sink 30 on one hand, and providing secondary heat dissipation to the serpentine heat sink 65 and water-cooling pipes 61 of the water-cooling assembly 60 on the other. Turbulence is generated as the air passes through the wavy grooves, increasing the contact area and time with the heat sink and enhancing heat exchange.

[0043] The horizontal air duct 31 and the vertical air duct 41 intersect perpendicularly to form a cross-shaped airflow channel, guiding air to form a three-dimensional flow on the surface of the radiator. The fan direction of the cooling modules 20 on both sides is coordinated with the air duct direction to further improve the airflow speed and uniformity, ensuring that heat is quickly dissipated into the environment.

[0044] This invention achieves uniform heat distribution through a Y-shaped column 12 and symmetrical heat dissipation assembly, while the integrated design reduces thermal resistance. The horizontal air duct 31 and the vertical air duct 41 form a three-dimensional convection, and the wave-shaped groove and serpentine heat sink 65 increase the heat exchange area and disturb the airflow, improving the air-side heat dissipation efficiency. The air-cooled and water-cooled components 60 work together, with water cooling quickly removing core heat and air cooling handling the remaining heat, adapting to high-power heat dissipation requirements. The mounting structure of the mounting strip 16 and mounting clip 64 ensures a stable connection of the cooling module 20, and the protective net 53 and sealing design enhance durability. The flexible installation method supports quick assembly and disassembly, and the controllable water circulation system adapts to different working conditions, improving engineering application scenarios.

[0045] The above description merely illustrates the preferred technical solution of this utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
