Frequently Asked Questions

What materials do you use for heat sinks?

We primarily use aluminum for extruded heat sinks due to its excellent thermal conductivity and lightweight properties. For high-performance applications, we use copper or copper-aluminum hybrid designs, especially in heat pipes and vapor chambers.

Can you customize heat sink designs?

Yes, we offer full OEM and ODM services. Our engineering team can customize fin geometry, base thickness, mounting options, and integrate heat pipes or vapor chambers based on your thermal requirements and space constraints.

What is the difference between passive and active cooling?

Passive heat sinks rely on natural convection and radiation to dissipate heat, making them silent and maintenance-free. Active heat sinks include a fan to force airflow, providing higher cooling capacity for high-power applications.

Do you provide thermal simulation data?

Yes, we perform thermal simulations during the design phase and can provide CFD results, temperature distribution maps, and thermal resistance data upon request for qualified projects.

What industries do you serve?

Our products are used in LED lighting, consumer electronics, industrial automation, power supplies, medical devices, stage and photography lighting, and telecommunications infrastructure.
