Processing Machines

The production of Friction Stir Welding cold plates requires special equipment, the most critical of which is FSW welding machines and high-precision CNC processing equipment. KingKa uses advanced CNC machine tools and special equipment for Friction Stir Welding, including:

FSW welding machine: used for efficient friction stir welding to ensure the strength and uniformity of the welding area.

CNC milling machines and lathes: used for precise sizing and surface treatment to ensure that the shape and size of the cold plate meet strict specifications.

Laser cutting machines and water jet cutting machines: these devices are used to accurately cut the cold plate to ensure smooth and burr-free cutting edges.

Surface treatment equipment: including sandblasting machines, polishing machines, etc., used to finely treat the surface of the cold plate to enhance its appearance and heat conduction effect.

Processing technology

The manufacturing process of Friction Stir Welding cold plate mainly includes the following steps:

Material preparation: Select suitable aluminum alloy or other metal materials and cut them into corresponding sizes according to design requirements.

Friction stir welding: Welding is performed through Friction Stir Welding technology to connect metal sheets and ensure that there are no defects in the welding area.

Precision machining: Use CNC machine tools for precision cutting, milling and other operations to ensure the accuracy and tolerance of the cold plate.

Surface treatment: Surface treatment of the cold plate, such as anodizing, sandblasting, polishing, etc., is performed to enhance its corrosion resistance and heat dissipation performance.

Quality inspection: Each cold plate undergoes a strict inspection procedure to ensure that the product meets the design requirements.

Materials and Precision

Friction Stir Welding cold plates often use aluminum alloys as the main material, especially high-strength aluminum alloys such as 2024 aluminum alloy, 6061 aluminum alloy, 7075 aluminum alloy, etc. These aluminum alloys have excellent thermal conductivity, corrosion resistance and mechanical properties, and are ideal for thermal management and heat dissipation products.

Processing accuracy is one of the key factors of Friction Stir Welding cold plates. KingKa strictly controls the dimensional tolerance during the production process to ensure that the accuracy of the cold plate can meet customer requirements. Usually, the accuracy of the cold plate can be controlled within ±0.1mm to ensure that it perfectly matches the customer's equipment or system.

In order to improve the service life and performance of Friction Stir Welding cold plates, surface treatment is particularly important. Common surface treatment methods include:

Anodizing: A protective film is formed on the surface of the cold plate by electrolysis to improve corrosion resistance and surface hardness.

Sandblasting: The sandblasting process is used to improve the surface finish of the cold plate and enhance its heat dissipation effect.

Polishing: Through mechanical polishing, the surface of the cold plate is made smoother, further improving the heat conduction efficiency.

These surface treatment processes enable the Friction Stir Welding cold plate to maintain good performance in various working environments and extend its service life.

The main function of the Friction Stir Welding cold plate is efficient thermal management, and it is widely used in electronic equipment, automobiles, communication equipment, aerospace and other industries. By optimizing the design and manufacturing process of the cold plate, its heat dissipation efficiency and working stability can be significantly improved to meet the needs of different fields.

Heat dissipation of electronic equipment

In electronic equipment, the Friction Stir Welding cold plate, as a thermal management solution, can effectively reduce the heat generated when the equipment is working and prevent overheating from damaging circuit boards and components. For example, computers, servers, LED displays and other products require efficient heat conduction materials to ensure stable operation.

Automotive industry

In the automotive industry, Friction Stir Welding cold plates are widely used in battery management systems (BMS) of electric vehicles, providing efficient thermal management solutions. The battery of an electric vehicle generates a lot of heat during charging and discharging. The use of Friction Stir Welding cold plates can effectively reduce the temperature of the battery and extend the battery life.

Aerospace

In the aerospace field, Friction Stir Welding cold plates are used in thermal management systems for spacecraft and aircraft to help control the temperature of engines and other high-temperature components. These cold plates must not only have efficient heat dissipation capabilities, but also meet the high strength and reliability requirements in extreme working environments.

Communication equipment

Communication equipment such as base stations and satellite communication systems have strict requirements for heat dissipation. The efficient thermal conductivity of Friction Stir Welding cold plates makes them an ideal choice for these devices, ensuring that the equipment will not fail due to overheating during long-term operation.
