Square Cold-Forged Heatsink for 60W LED Applications

GlacialTech Inc. today launches a new cold forged heatsink for 60W LED thermal solutions – Igloo FS127. Using a pin-fin heatsink design for better airflow and surface area, the Igloo FS127 features a very efficient 0.89 degrees C / W thermal resistance, appropriate for high-performance LED applications up to 60W. Anodized surface treatment gives the Igloo FS127 corrosion resistance, scratch-resistance, and heat tolerance, making it more physically robust than untreated aluminum.

Compared to straight fin designs, the pin fin Igloo FS127 performs well regardless of orientation, making them well-suited for lighting applications. A square heatsink shape accommodates square-type lighting fixture designs. The Igloo FS127’s low thermal resistance is achieved through a combination of cold forging as well as high performance materials. Cold forging produces heat sinks with better thermal characteristics and easier assembly than traditional die-casting or aluminum extrusion.

With the AL1050 aluminum used in the Igloo FS127, thermal conductivity is 2.36 times better compared to die casting; from 96.2 W/mK to 227 W/mK. Cold forging allows more complex shapes, and the Igloo FS127 is a one-piece design with no assembly required.
