What is a Round Pin Heatsink?

Copper Round pin heatsinkA Round Pin Heatsink was developed for low air flow environments. The round shaped pins are set in a pattern that makes it easier for air to efficiently flow through the heat sink. A Round Pin Heatsink is ideal for omni-directional situations as the airflow can come from any direction, and changes in airflow patterns only have a minimum impact on performance. Round Pin Heatsinks provide an effective cooling mechanism by fanning out of the heatsink fins within given space environment, and can dissipate heat at much higher rates in low ventilation circumstances when compared with the normal flat fin heatsink design.thermal Round Pin Heatsink

Round Pin Heatsinks can be manufactured from both Aluminum, and copper by various methods. The most efficient Round Pin Heatsinks are forged that allows for both high aspect ratio designs, and also highly conductive materials to optimize this heatsink for highly demanding thermal environments.

Radian Thermal Products offers a wide range of copper and aluminum round pin heatsinks in both standard, and custom designs. Many engineers are now using the Round Pin Heatsink in innovative ways to efficiently deal with challenging thermal requirements.
