In the current era of continuous upgrading of industrial automation, servo drives, as the "moving heart" of modern equipment, have a direct impact on the accuracy and stability of equipment operation in terms of their performance. As a key component to ensure the stable operation of servo drives, the heat sink die-casting of servo drives is undergoing profound technological changes, injecting new impetus into the efficient operation of industrial equipment.

Recently, several companies have made breakthrough progress in the field of die-casting parts for servo drive heat sinks. A well-known heat dissipation technology enterprise has developed a new type of needle wing aluminum die-casting heat sink. With its unique needle wing structure design, it significantly increases the heat dissipation area and has a thermal conductivity of over 200W/m · K. Compared to traditional radiators, this product has increased its heat dissipation efficiency by 35% under the same volume. This innovative design enables the servo drive to quickly dissipate heat during high load operation, effectively avoiding performance degradation and malfunctions caused by overheating, and ensuring the continuous and stable operation of the equipment. In the string welding equipment of the photovoltaic industry, the servo driver using this heat sink can shorten the positioning time of each cell to 0.15 seconds, significantly improving production efficiency.

At the same time, another enterprise focuses on optimizing the die-casting process, achieving high-precision manufacturing of radiator die-casting parts by introducing advanced low-pressure die-casting technology and intelligent temperature control systems. During the die-casting process, the intelligent temperature control system can accurately control the temperature fluctuation of the mold within ± 1 ℃, ensuring that the metal liquid uniformly fills the mold cavity, effectively reducing defects such as shrinkage and porosity, and greatly improving the quality and performance of the radiator. After testing, the heat sink produced using this process has a consistent heat dissipation performance deviation controlled within 5%, providing a more reliable heat dissipation guarantee for servo drives.

In addition, to meet the heat dissipation needs of servo drives under special working conditions, some companies are also committed to developing new heat dissipation materials and structures for heat sink die-casting parts. For example, an 80kW high-power servo drive radiator die casting using heat pipe temperature equalization technology has emerged. This product utilizes the efficient thermal conductivity of heat pipes, which can quickly and evenly distribute heat to the entire surface of the heat sink, keeping the temperature rise of the drive within 35 ℃. Even in extremely harsh environments, it can ensure stable operation of the servo drive. This innovative radiator has been widely used in high load equipment such as shield tunneling machines and large industrial robots, effectively improving the reliability and service life of the equipment.

The technological innovation of servo drive heat sink die-casting not only provides a more powerful heat dissipation solution for industrial automation equipment, but also promotes the upgrading and development of related industries. With the deep integration of emerging technologies such as 5G and the Internet of Things with industrial manufacturing, the performance requirements for servo drives will become increasingly stringent in the future. As a key supporting component, heat sink die-casting parts are expected to continue to break through in material innovation, process optimization, and other aspects, providing solid support for the intelligent and efficient development of the industrial field.
