Frequently Asked Questions: Telecom Thermal Solutions

Leak prevention is our top priority. We utilize advanced Friction Stir Welding (FSW) and Vacuum Brazing to create defect-free, solid-state joints. Furthermore, every plate undergoes mandatory pressure retention testing (e.g., 1MPa) and Helium leak detection prior to shipping.

It depends on the power density. For extreme heat loads, sealed FSW liquid cold plates are optimal. For passive cooling, we recommend our custom skived fin heat sinks treated with specialized anti-corrosion coatings (like hard anodizing) to withstand harsh outdoor environments like salt fog and humidity.

Yes. High-speed transceivers require ultra-precise temperature control to maintain wavelength stability. We manufacture micro-channel liquid cold plates and ultra-thin skived heat sinks with exceptional flatness (±0.005mm) to ensure perfect thermal contact with optical modules.

Absolutely. Our in-house engineering team uses advanced CFD (Computational Fluid Dynamics) software to simulate airflow, pressure drop, and heat dissipation based on your specific telecom application, ensuring the design is optimized before manufacturing begins.

Through our highly controlled skiving process, we can achieve fin thicknesses as thin as 0.1mm with tight spacing. This dramatically increases the total surface area for heat dissipation, making it ideal for the extreme space constraints of 1U and 2U telecom enclosures.

For standard applications, high-purity aluminum alloys (6061/6063) offer an excellent balance of weight, cost, and thermal conductivity. For BBUs with extreme hot spots, we often incorporate copper bases or embed heat pipes/vapor chambers into the aluminum assembly to rapidly spread the heat.
