What is a Elliptical Fin Heatsink?

Elliptical Fin HeatsinkA Elliptical Fin Heatsink is designed to reduce vortex effects by minimizing the pressure loss across the heat sink. In its simplest form an elliptical fin heatsink can be made by taking an extruded platefin heatsink, and then making cross-cuts at regular intervals. A better shape can be created by using the forging process to create the fin in a ellipsis shape.Compared with standard plate fin heatsink the elliptical fin offers a higher transfer of heat in environments with low airflow. Compared with a RoundPin Heatsink, the cross cuts create a larger exposed surface to transfer more heat.Elliptical fin heatsinks deliver exceptional results when placed in applications that involve multiple heatsinks lined up against one another, as the fins allow a large amount of airflow to go on to the next heatsinks in the chain, reducing the effect of air blocking, and increasing ventilation from the cool air.

thermal heatsinkRadian's aluminum elliptical fin BGA heatsinks are cold forged using high pressure and low temperature to ensure no air bubbles, or other impurities are trapped in the material.  This improves the thermal properties of the heatsink, and increases the density of the material. Radian Thermal Products utilizes special open die tooling and intense pressure to produces high precision heatsinks with high aspect ratios.These  high efficiency cooling products which are ideal for linear air-flow environments.

BGA Aluminum Elliptical Fin Heatsink

Radian’s INM-W BGA Aluminum Elliptical Fin Heatsink is an  off-the-shelf device that can be mounted with EZ Snap™ Mounting Clips combined with a TIM (Thermal Interface Material), Thermal Tape or Epoxy to provide optimum cooling for various package sizes and airflow. Using the EZ Snap™ Mounting Clips provides easy installation that requires no special board modifications or complex assemblies.
