Dissipador de calor de nitreto de alumínio

Características de Design

Aluminum nitride heat sink, also known as high thermal conductivity ceramic cooling plate, leverages the high thermal conductivity and electrical insulation of aluminum nitride (AlN), providing efficient thermal management solutions for electronic devices:

Alta Condutividade Térmica

Aluminum nitride has a thermal conductivity of up to 170 W/m·K, allowing it to rapidly absorb and conduct heat from sources such as semiconductor devices, effectively dissipating heat to the surroundings through the large surface area of the heat sink.

Excelente Isolamento Elétrico

With a breakdown strength as high as 17-19 KV/mm and low dielectric loss, aluminum nitride heat sinks provide outstanding thermal management capabilities without compromising electrical insulation.

Baixo Coeficiente de Expansão Térmica

Its thermal expansion coefficient of 3.2-3.4×10^-6/ºC, similar to that of silicon, ensures excellent compatibility with semiconductor materials during temperature variations, reducing stress caused by thermal expansion differences.

Boa Estabilidade Térmica

It can be used in oxygen-rich environments up to 1000°C and maintains stability with a thermal shock resistance of 400°C, making it suitable for operations in high-temperature environments.

Smooth Surface and Uniform Thickness

This helps improve thermal contact efficiency, reduce thermal resistance, and enhance heat dissipation performance.

Áreas de Aplicação

Aluminum nitride heat sinks play a crucial role in many high-tech fields, especially in applications that require efficient heat dissipation:

High-Performance Computing Devices

Such as servers and workstations, these devices generate significant heat and require efficient cooling to maintain stability and high efficiency operation.

Power Semiconductors and Power Electronics

Including inverters and drive systems for electric vehicles, the heat generated by power components in these systems needs to be controlled through efficient thermal management.

LED Lighting Equipment

LED components generate high heat, and using aluminum nitride heat sinks can extend the lifespan of LEDs and maintain light efficiency.

Electronic Packaging

Aluminum nitride heat sinks are also widely used in semiconductor packaging, helping to reduce heat accumulation inside the package and improve overall device performance and reliability.

Aluminum nitride heat sinks play a critical role in modern electronic manufacturing with their excellent thermal conductivity and electrical insulation, especially in high-temperature and high-power applications. These heat sinks not only enhance equipment operating efficiency and stability but also significantly extend device lifespan through optimized thermal management. Their high performance and reliability make aluminum nitride heat sinks an ideal choice for electronic device cooling, meeting the growing thermal management needs of high-performance electronic devices.
