Structure & Manufacturing Process
Structural features: This type of heat sink is usually composed of an internal copper heat dissipation component and an external aluminum structure. Copper heat dissipation components can be in the form of copper tubes, copper sheets, etc., which have good thermal conductivity and can quickly absorb heat; The aluminum structure serves as the main frame and heat dissipation fin part of the radiator, and the advantages of aluminum are light weight, relatively low cost and easy to process and form, which can provide a large heat dissipation area and help the heat to dissipate quickly.
Manufacturing process: In the manufacturing process, the copper heat dissipation component is first prepared and complete, and then it is stably set in the anti-gravity die-casting mold, and then the aluminum is closely combined with the copper heat dissipation component through die-casting to form a copper-aluminum composite. After that, it undergoes specific heat treatment, such as (T4+T6) heat treatment, to improve the overall performance of the heat sink, including hardness and dimensional stability.
Performance Advantages
Excellent heat dissipation performance: copper has a high thermal conductivity, which can quickly conduct heat from the heat source to the heat sink; Aluminum has a large heat dissipation area, which can quickly dissipate the heat conducted into the surrounding environment. The combination of aluminum and copper greatly improves the heat dissipation efficiency of the heat sink, which can meet the application scenarios with high heat dissipation performance requirements such as high-power electronic devices and lasers.
Good corrosion resistance: Copper has good corrosion resistance, and can effectively resist the erosion of water, air and other media on the radiator in the harsh working environment. The alumina film formed on the surface of the aluminum also has some resistance to corrosion, and the combination of the two makes the radiator have a long service life.
High dimensional stability: After special heat treatment and die-casting process, the aluminum-copper integrated die-casting composite radiator can maintain good dimensional stability in different temperature environments. Whether it is in a high-temperature working state or a low-temperature environment, the structure of the radiator will not be significantly deformed or damaged, ensuring the stability of its heat dissipation performance.
High mechanical strength: The combination of aluminum and copper makes the radiator have high mechanical strength and can withstand certain external force impact and vibration. In some application scenarios with high requirements for the mechanical stability of radiators, such as automobiles, industrial equipment, etc., aluminum-copper integrated die-casting composite radiators have good adaptability.
Applications
Electronic equipment: It is widely used in computers, mobile phones, servers and other electronic equipment, which can effectively dissipate the heat generated by electronic components when they work to ensure the normal operation and service life of electronic equipment.
Laser field: Lasers generate a lot of heat when they are working, and efficient heat sinks are required to dissipate heat. The high heat dissipation performance and dimensional stability of the aluminum-copper integrated die-casting composite heat sink make it an ideal choice for laser heat dissipation.
Automotive: It can be used for heat dissipation of key components such as automobile engines and transmissions, helping automobiles maintain good working temperatures under various working conditions, and improving the performance and reliability of automobiles.
Industrial equipment: In various industrial equipment, such as CNC machine tools, injection molding machines, printing machines, etc., aluminum-copper integrated die-casting composite heat sinks can provide effective heat dissipation guarantee for key components of equipment, reduce the failure rate of equipment, and improve production efficiency.
