Effective thermal management is fundamental to system reliability and performance. As power densities increase across data centers, industrial controls, and high-performance computing, managing heat efficiently through air-cooled solutions remains one of the most reliable and scalable approaches available.
Radian Thermal Products offers an array of air-cooled heat sinks, combining proven manufacturing processes with precision engineering to meet performance, weight, and cost targets across industries.
Air cooling uses the surrounding air to remove the heat generated by electronic components, via a heatsink.
For higher power dissipations a fan is used to force air across a densely finned heatsink. The heat is transferred through the metal of the heatsink through conduction, before being dissipated into the moving air via convection off the surface of the heatsink fins. Radiation plays a negligible part in forced air cooling.
For lower power dissipations a less densely finned heatsink can be used. The heat is transferred through the metal of the heatsink through conduction, before being dissipated via natural convection and radiation off the surface of the heatsink fins. The effectiveness of air cooling depends on several critical parameters:
These parameters ensure stable thermal performance and system reliability, even in environments where space and airflow are limited.
Liquid Cooling Technology for High Performance
As thermal densities of components increases, a greater emphasis is placed on effective thermal management to eliminate localised high temperatures and thermal stress.
While liquid cooling offers high capacity, air cooling remains the preferred method for most OEMs for the following reasons:
Heat Sinks: The Primary Heat Exchanger
Heatsinks are the central component in any air cooling system. They absorb heat from the source and transfer it to the surrounding air through conduction, convection and radiation. At Radian, we design and manufacture heatsinks to meet project-specific thermal, mechanical, and manufacturing requirement.
Fans: Driving Forced Airflow
When natural convection is insufficient, forced-air cooling enhances heat transfer. Radian’s fan-integrated assemblies are designed to:
These assemblies are tested for vibration, acoustic performance and reliability under continuous operation.
Data Center, Cloud Infrastructure & AI
High-density processors and GPUs require consistent thermal regulation under sustained workloads. Radian’s air-cooled assemblies are engineered for optimal airflow management and heat dissipation, ensuring performance continuity and reduced thermal throttling.
Industrial and Specialized Equipment
From factory automation to medical devices, thermal reliability defines uptime.
Radian’s manufacturing versatility enables OEMs to specify the optimal heatsink technology for their environmental and operational constraints — whether ruggedized, lightweight or precision-machined.
