Radian Thermal Products Inc.

Radian Thermal Products has been committed to helping our customers with full-service thermal solutions delivered to a variety of industries since 1974. Radian Thermal Products offers both standard, and custom heatsinks for a wide range of applications including Plate fin heatsinks, Round pin Heatsinks, Elliptical Finned heatsinks, and Fansinks. Radian’s heatsinks are manufactured using all the standard methods including machining, extrusion, die-casting, forging, stamping, and skiving.

Our EZ Snap clip provides high performance while not requiring any board changes. This is very useful when solving thermal issues that are identified late in development when the PCB is fixed, and a redesign would be costly, or take too long. The design also reduces any impact on nearby component placement, and is useful with high density designs as signal routing is not compromised.

Heatsink Types

With over 40 years of experience, Radian Thermal Products has manufactured all major types of heatsinks that are available. If the particular style is not shown, please contact our team to discuss your needs.

Plate Fin Heatsinks

Platefin Heatsink

Plate Fin Heatsinks are optimized for airflow which is unidirectional and parallel to the fins

Round Pin Heatsinks

copper roundpin heatsink

Round Pin Heatsinks are suitable for environments with low, angled or variable airflows

Elliptical Fin Heatsinks

Elliptical Fin Heatsink

Elliptical Fin Heatsinks reduce vortex effects and are ideal for low airflow



Fansinks provide airflow for more challenging thermal environments

Vapor Chambers

vapor chamber with Stamped Fin heatsink

Vapor chambers use aluminum or copper fins for high performance

Heat Pipes

heatsink with heatpipe

Heatpipes transfer heat away from the source to spread the heat

Heatsink Manufacturing Processes

Founded as a casting company in 1974, Radian Thermal Products has used a wide range of manufacturing methods to create heatsinks, and many other types of products. All major manufacturing methods for Aluminum, and Copper are available. If the particular manufacturing method is not shown below, please contact our team to discuss your needs.

Machined heatsinks

Custom Heatsink

Machined Heatsinks are an ideal choice for smaller production requirements as there is no Non Recurring Engineering charge

Extruded Heatsinks

Extruded heatsink

Extruded Heatsinks are manufactured when material is pushed through a die of the desired cross-section

Die-Cast Heatsink

Diecast heatsink

A Die-cast Heatsink uses the process of forcing molten metal into a molded cavity under high pressure

Skived Heatsinks

Skived Heatsink

Skived Heatsinks offer excellent thermal properties as they are manufactured using a single Aluminum, or Copper block

Forged Heatsinks

Forged Heatsink

Forged Heatsinks are manufactured by the shaping of metal using localized compressive forces

Stamped Fin Heatsinks

Stamped Fin Heatsink

Stamped Fin Heatsinks can be made in Aluminum, or Copper, and typically used with vapor chambers

Thermal Solutions for tough requirements

We provide rapid, and innovative thermal solutions for world wide leaders in many market segments including Storage, Telecom, and Wireless broadband. With the continual need to process data faster, heat is a major issue, and thermal problems are often not apparent until beta testing. Our experienced team will assist your engineers to resolve these issues before they become a serious problem. Our Thermal Engineers are also available to conduct thermal analysis and create design solutions that are both cost effective, and production proven.
