Description

Technical Field

[0001] This utility model relates to the field of high-reliability aluminum plate-fin radiators, specifically to a high-reliability aluminum plate-fin radiator core assembly. Background Technology

[0002] High-reliability aluminum plate-fin radiators are heat dissipation devices that combine the excellent properties of aluminum with the efficient heat dissipation design of plate-fin radiators. Aluminum plate-fin radiators use aluminum as the main component material. Aluminum has excellent thermal conductivity, is lightweight, and is corrosion-resistant, making it an ideal material for radiator manufacturing. Through a specific process, thin aluminum fins are tightly bonded to the base tube, greatly increasing the heat dissipation area and thus improving heat transfer efficiency. High-reliability aluminum plate-fin radiators are renowned for their material advantages, structural features, high reliability, and wide range of applications. The core assembly is a key component of the radiator. The core assembly utilizes the heat exchange between the fluid (gas or liquid) and the fins as it passes through channels, transferring heat to the fins, which then dissipate the heat into the air. This structure gives the radiator high heat dissipation efficiency and structural strength.

[0003] In the use of existing high-reliability aluminum plate-fin radiator core components, the fins are simply arranged on the partition before assembly and welding. This results in a limited heat transfer coefficient on the fin surface and restricts heat dissipation performance. Furthermore, with the fins located in the middle of the partition under long-term use, the overall structure lacks stability during welding and assembly, which affects the structural strength, durability, and reliability of the high-reliability aluminum plate-fin radiator core components.

[0004] Therefore, it is necessary to invent a high-reliability aluminum plate-fin radiator core assembly to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a high-reliability aluminum plate-fin radiator core assembly. Through a lower partition, a first metal mesh, corrugated fins, turbulence-inducing grooves, a second metal mesh, an upper partition, and longitudinal guide grooves, this assembly improves heat dissipation efficiency, optimizes fluid flow characteristics, enhances structural strength and durability, and increases reliability and stability. This expands the application range of the core assembly. It addresses the problems in existing high-reliability aluminum plate-fin radiator core assemblies where, before assembly and welding, the fins are simply arranged on the partition. This results in limited heat transfer coefficients on the fin surface and restricted heat dissipation performance. Furthermore, long-term use with the lower fins positioned in the middle of the partition leads to a lack of overall stability during welding and assembly, negatively impacting the structural strength, durability, and reliability of the high-reliability aluminum plate-fin radiator core assembly.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-reliability aluminum plate-fin radiator core assembly, including a fin radiator core base, which is the main body for heat dissipation;

[0007] A lower partition is disposed above the finned radiator core seat for core assembly, and a front end seal is fixedly installed on the upper part of the lower partition. A rear end seal is provided on one side of the front end seal, and a first metal mesh is fixedly installed on the upper part of the lower partition.

[0008] A corrugated fin is disposed above the first metal mesh to improve heat dissipation efficiency. The surface of the corrugated fin is provided with turbulence-inducing grooves. A second metal mesh is disposed above the corrugated fin. An upper partition is fixedly installed above the second metal mesh. The surface of the upper partition is provided with longitudinal flow guide grooves. A layered fastening bolt passes through the upper part of the front end seal.

[0009] Preferably, the corrugated fins are movably connected to the front sealing strip, and the first metal mesh is fixedly connected to the lower partition.

[0010] Preferably, the number of the turbulence protrusions and grooves is set to multiple, and the multiple turbulence protrusions and grooves are distributed at equal intervals on the corrugated fin.

[0011] Preferably, a first lateral partition is provided above the upper partition, a first lateral mesh is fixedly installed above the first lateral partition, and lateral fins are provided above the first lateral mesh.

[0012] Preferably, a second lateral mesh is fixedly installed above the lateral fins, and a second lateral partition is provided above the second lateral mesh.

[0013] Preferably, a connecting column is fixedly installed above the finned radiator core base, an upper sealing seat is fixedly installed on the top of the connecting column, and a double-headed bolt passes through the top of the connecting column.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] This utility model includes a lower partition, a first metal mesh, corrugated fins, turbulence-inducing grooves, a second metal mesh, an upper partition, and longitudinal guide channels. When using this high-reliability aluminum plate-fin radiator core assembly, the core assembly is not simply assembled with fins and partitions before assembly. Instead, a first metal mesh and a second metal mesh are added between the lower and upper partitions. This increases the connection strength between the corrugated fins and the lower and upper partitions, improves the overall structural strength of the radiator core, and also provides wear protection, extending the service life of the radiator core. Furthermore, the corrugated fins are not simply arranged when positioned between the front and rear sealing strips. The surface of the corrugated fins is provided with multiple turbulence-inducing protrusions and grooves. The design of the turbulence-inducing protrusions and grooves can increase the surface area and complexity of the radiator core, thereby improving its resistance to deformation and fatigue, breaking the original heat dissipation efficiency limitation of the corrugated fins, and further improving its heat dissipation effect and durability. In addition, multiple longitudinal flow guide grooves are provided on the upper baffle plate, which can change the flow direction of the fluid on the surface of the baffle plate, realize the counterflow heat exchange, and thus improve the heat exchange efficiency. When used together, it has the benefits of improving the heat dissipation efficiency of the core component, optimizing fluid flow characteristics, enhancing structural strength and durability, and improving reliability and stability, thus expanding the application range of the core component.

[0016] This utility model features layered fastening bolts, a first lateral partition, a first lateral mesh, lateral fins, a second lateral mesh, and a second lateral partition. When using this high-reliability aluminum plate-fin radiator core assembly, the first lateral partition, lateral fins, and second lateral partition are assembled in reverse order above the originally horizontally assembled lower partition, corrugated fins, and upper partition. This gives the high-reliability aluminum plate-fin radiator core assembly a layered structure. The layered structure can distribute stress across multiple layers, preventing excessive local stress from causing deformation of the fins or partitions. Changing the fin orientation can reduce fatigue damage to the fins and partitions during long-term operation, guide the fluid to form a more complex flow pattern on the fin surface, and increase the number of heat exchanges between the fluid and the fins. This design significantly improves the radiator core assembly in terms of heat dissipation efficiency, structural strength, adaptability, and flexibility. Attached Figure Description

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figure 1-5 The invention relates to a high-reliability aluminum plate-fin radiator core assembly, which includes a fin radiator core base 1, a main body for heat dissipation.

[0027] The lower partition 2 is located above the finned radiator core seat 1 and is used for core assembly. A front end seal 3 is fixedly installed on the upper part of the lower partition 2, and a rear end seal 4 is provided on one side of the front end seal 3. A first metal mesh 5 is fixedly installed on the upper part of the lower partition 2.

[0028] Corrugated fins 6 are positioned above the first metal mesh 5 to improve heat dissipation efficiency. The surface of the corrugated fins 6 is provided with turbulence-inducing grooves 7. A second metal mesh 8 is positioned above the corrugated fins 6, and an upper partition 9 is fixedly installed above the second metal mesh 8. The surface of the upper partition 9 is provided with longitudinal flow guide grooves 10. A layered fastening bolt 11 passes through the upper part of the front sealing strip 3. The corrugated fins 6 are provided with multiple turbulence-inducing grooves 7. The design of the turbulence-inducing grooves 7 can increase the surface area and complexity of the radiator core, thereby improving its resistance to deformation and fatigue, breaking the original heat dissipation efficiency limitation of the corrugated fins 6, and further improving its heat dissipation effect and durability. In addition, the upper partition 9 is also provided with multiple longitudinal flow guide grooves 10, which can change the flow direction of the fluid on the surface of the partition and realize the countercurrent heat exchange, thereby improving the heat exchange efficiency.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, the corrugated fins 6 are movably connected to the front sealing strip 3, and the first metal mesh 5 is fixedly connected to the lower partition 2. A first metal mesh 5 and a second metal mesh 8 are added between the lower partition 2 and the upper partition 9. This increases the connection strength between the corrugated fins 6 and the lower and upper partitions 2 and 9, improving the overall structural strength of the radiator core. Multiple turbulence-inducing grooves 7 are provided, and these grooves are evenly distributed on the corrugated fins 6. The design of the turbulence-inducing grooves 7 increases the surface area and complexity of the radiator core. This improves its resistance to deformation and fatigue. A first lateral partition 12 is provided above the upper partition 9. A first lateral mesh 13 is fixedly installed above the first lateral partition 12. A lateral fin 14 is provided above the first lateral mesh 13. Above the originally horizontally assembled lower partition 2, corrugated fin 6 and upper partition 9, the first lateral partition 12, lateral fin 14 and second lateral partition 16 are assembled in three layers with their directions reversed. This gives the high-reliability aluminum plate-fin radiator core assembly a layered structure.

[0030] like Figure 1 , Figure 4 and Figure 5 As shown, a second lateral mesh 15 is fixedly installed above the lateral fins 14, and a second lateral baffle 16 is provided above the second lateral mesh 15. The change in the orientation of the lateral fins 14 can reduce fatigue damage to the fins and baffles during long-term operation, guide the fluid to form a more complex flow pattern on the fin surface, and increase the number of heat exchanges between the fluid and the fins. A connecting column 17 is fixedly installed above the finned radiator core seat 1, and an upper sealing seat 18 is fixedly installed on the top of the connecting column 17. A double-headed bolt 19 passes through the top of the connecting column 17. The upper sealing seat 18 has a simple overall structure, which is not only easy to operate, but also facilitates the assembly and welding of the high-reliability aluminum plate finned radiator core assembly.

[0031] The working principle of this practical system is as follows: Before welding and assembling the core assembly of the high-reliability aluminum plate-fin radiator, the following components are placed sequentially above the radiator core base 1: lower partition 2, front end seal 3, rear end seal 4, first metal mesh 5, corrugated fins 6, second metal mesh 8, and upper partition 9. Thus, the core assembly is not simply fins plus partitions before assembly; instead, the first metal mesh 5 and the second metal mesh 8 are added between the lower partition 2 and the upper partition 9. This increases the connection strength between the corrugated fins 6 and the lower and upper partitions 2 and 9, improves the overall structural strength of the radiator core, and also provides wear protection, extending heat dissipation time. The service life of the heat sink core is affected by the fact that the corrugated fins 6 are not simply arranged when they are between the front end seal 3 and the rear end seal 4. Multiple turbulence-inducing grooves 7 are provided on the surface of the corrugated fins 6. The design of these grooves increases the surface area and complexity of the heat sink core, thereby improving its resistance to deformation and fatigue, breaking the original heat dissipation efficiency limitations of the corrugated fins 6, and further improving its heat dissipation effect and durability. Then, multiple longitudinal flow channels 10 are provided on the upper partition 9 to change the flow direction of the fluid on the partition surface, achieving counter-current heat exchange and thus improving heat exchange efficiency. Finally, these three layers of components are arranged... After tightening the layered fastening bolts 11, the first lateral baffle 12, lateral fins 14, and second lateral baffle 16 can be assembled above the originally horizontally assembled lower baffle 2, corrugated fins 6, and upper baffle 9, with the three layers reversed in orientation. This gives the high-reliability aluminum plate-fin radiator core assembly a layered structure. The layered structure can distribute stress across multiple layers, preventing excessive local stress from causing deformation of the fins or baffles. Furthermore, changing the fin orientation can reduce fatigue damage to the fins and baffles during long-term operation, guiding the fluid to form a more complex flow pattern on the fin surface, increasing fluid-to-fin interaction. The number of heat exchange cycles between the fins is determined. After all the components are assembled and placed, the sealing seat 18 is installed using double-headed bolts 19. In this way, the high-reliability aluminum plate-fin radiator core assembly is assembled as a single unit and can be welded. After the high-reliability aluminum plate-fin radiator core assembly is welded, it can be assembled and used normally with other high-reliability aluminum plate-fin radiator frames. Finally, after completing the installation and use of all high-reliability aluminum plate-fin radiator core components according to the above operations, routine maintenance of the device is required. This completes the usage process of the high-reliability aluminum plate-fin radiator core assembly.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
