Applications of Aluminum Nitride High Thermal Conductivity Wear Ring

Aluminum nitride’s high thermal conductivity wear ring has become a key material in many cutting-edge fields due to its excellent performance.

In the field of electronics and information, with the rapid development of 5G communication and artificial intelligence technology, the integration degree and operation speed of chips are increasing, and the problem of heat generation is becoming more and more serious. Aluminum nitride high thermal conductivity wear ring can quickly export the heat generated by the chip, and its excellent thermal conductivity can reduce the chip junction temperature by 15-20 ℃, effectively avoiding performance degradation and life-shortening due to overheating and building a solid foundation for the stable operation of servers, data centers and other large-scale electronic equipment.

In high-power semiconductor devices, such as IGBT modules, aluminum nitride high thermal conductivity wear rings not only undertake the important task of heat dissipation but also, by virtue of good insulation, ensure the safe operation of the device in the high-voltage, high-current environment.

The new energy automobile industry has very high requirements for heat dissipation and reliability, and aluminum nitride high thermal conductivity wear rings play an important role in vehicle inverters. The inverter generates a lot of heat in the process of power conversion, and the use of this wear-resistant ring can quickly dissipate the heat and increase the efficiency of the inverter by 3%-5%. At the same time, its wear-resistant characteristics can adapt to the vibration and impact of the vehicle environment and ensure the long-term stable operation of the equipment.

The battery management system can accurately control the temperature of the battery pack, avoiding the safety hazards caused by local overheating, improving the battery range and service life, and providing technical support for the popularization and development of new energy vehicles.

 In the field of machining, the high-speed operation of machine tools, automated production lines and other equipment puts forward stringent requirements on the wear resistance of components. Aluminum nitride high thermal conductivity wear ring, as the key moving parts of the protective ring, can withstand up to 10m / s more than the linear speed of friction; its wear resistance can make the parts of the abrasion amount by more than 60%, significantly reducing the frequency and cost of equipment maintenance. Precision machining equipment can also quickly conduct the heat generated by the cutting process, prevent the tool from overheating and wearing, and improve machining accuracy and surface quality.

In the aerospace field, aluminum nitride’s high thermal conductivity wear ring with excellent high-temperature resistance and radiation resistance performance is used in aviation engines, satellite electronic equipment and other key parts. In extreme high-altitude environments, it can not only efficiently dissipate heat to ensure the normal operation of the equipment but also resist high-speed airflow wash and space particle radiation to enhance the reliability and safety of the aircraft.

In the field of medical devices, especially CT, MRI, and other large-scale medical equipment, aluminum nitride high thermal conductivity wear ring can help equipment rapid heat dissipation to ensure the stability and accuracy of the imaging system; at the same time, it good biocompatibility and chemical stability, to avoid adverse effects on the human body, to provide reliable protection for medical diagnosis and treatment.

5 FAQs of Aluminum Nitride High Thermal Conductivity Wear Ring

Q1: Will the performance of Aluminum Nitride High Thermal Conductivity Wear Rings degrade after long-term use?

Under normal working conditions, aluminum nitride wear rings can last for several years. However, high temperature, high humidity or high stress environments may accelerate wear or hydrolysis. It is recommended to check the surface wear regularly (if grooves are present, they need to be replaced promptly).

Q2: Do Aluminum Nitride products meet environmental standards?

Most Aluminum Nitride ceramics comply with the ROHS directive and are free of lead, mercury and other hazardous substances, and are suitable for use in electronic and electrical equipment. Some manufacturers also provide FDA-certified products to meet the needs of the medical field.

Q3: Do you support customization of Aluminum Nitride high thermal conductivity wear rings?

Aluminum nitride rings can be customized according to size (e.g., inner diameter 6-410mm, thickness 2-20mm), shape (toroidal, shaped), and performance requirements (e.g., higher thermal conductivity or hardness), depending on the drawings or parameter requirements.

Q4: What is the price of an Aluminum Nitride High Thermal Conductivity Wear Ring?

Prices vary depending on specifications, process and batch size. The unit price for small-size samples is about $10-100, while large-size or high-precision products can be up to thousands of dollars. It is recommended to contact the supplier for a customized quote.

Q5: Is aluminum nitride fragile?

Although Aluminum Nitride ceramics have high hardness, they are brittle and need to avoid impacts or collisions with sharp objects. Impact resistance can be improved by optimizing the structural design (e.g., adding chamfers) or using composite processes (e.g., embedding with metal).
