Radian Thermal Products Inc.

Standard and custom Thermal Solutions

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.

Featured Product - PCIe heatsink

PCIe Heatsink

A PCIe heatsink is specifically designed for a PCI Express card that has a max height of 14.48mm. These PCIe heatsinks are also useful for other low profile applications. We offer pushpin, stick-on, screw, and BGA EZ-Snap heatsink versions.

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

Round pin Heatsinks

copper roundpin heatsink
Round Pin Heatsinks are suitable for environments with low airflows

Elliptical Fin Heatsinks

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

5 or 12 volt Fansinks

Fansink
Fansinks provide airflow for more challenging thermal environments

Vapor Chamber Heatsinks

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 heatsinks

Diecast heatsink

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

Stamped Fin heatsinks

Stamped Fin Heatsink

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

Al/Cu Skived heatsinks

Skived Heatsink

Skived Heatsinks offer excellent thermal performance and are manufactured using a single metal block

Al /Cu Forged heatsinks

Forged Heatsink

Forged Heatsinks are manufactured by the shaping of aluminum or copper using localized compressive forces

Thermal Solutions for tough requirements

Thermal Analysis

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.
