The main function of thermal management materials is to quickly conduct the heat generated by electronic components away, preventing performance degradation, shortened lifespan, or even damage due to overheating. From mobile phones and tablets to high-performance computers, servers, and complex electronic systems in automotive electronics and aerospace, thermal management materials are everywhere and are key to ensuring stable device operation. 。

Currently, common thermal management materials on the market include metal-based materials (such as copper, aluminum, and their alloys), ceramic materials (such as alumina and aluminum nitride), carbon materials (such as graphite, carbon nanotubes, graphene), and various composites. Each of these materials has its advantages and disadvantages; for example, metal materials have good thermal conductivity but are relatively heavy, ceramic materials have high thermal stability but are difficult to process, and carbon materials have excellent thermal and mechanical properties but are costly. To meet the increasing demands for thermal management materials in different fields, the processing technology of these materials has become particularly critical.

In terms of nanoscale precision in particle size control, vertical mills can achieve submicron-level particle uniformity through a vertical stirring shaft and precise control of the grinding media's movement trajectory. For example, in the processing of nano-ceramic thermal management materials, when grinding raw materials such as alumina and aluminum nitride, the particle size can be precisely controlled to achieve a nanoscale uniform distribution, significantly enhancing the material's thermal conductivity and mechanical properties. For carbon-based thermal management materials like graphite and carbon nanotubes, fine grinding with vertical mills can effectively improve their crystal structure, increase crystallinity and orientation, thereby enhancing thermal conductivity.

Vertical mills adopt a closed grinding chamber design, effectively reducing the emission of dust and other pollutants, avoiding harm to the production environment and the health of operators. Some advanced vertical mills are also equipped with dust collection and treatment systems, further improving environmental performance and aligning with the current trend of green manufacturing.

For ceramic thermal management materials, their flexural strength can be increased after grinding. By more than 50%, making them more reliable under mechanical stress and less prone to cracking. In applications with high mechanical performance requirements, such as heat dissipation components in automotive engines, using thermal management materials processed by vertical mills can extend component lifespan and reduce failures caused by material damage.
