GlacialTech Announces Square Cold Forged Heatsink for 60W LED applications – Igloo FS127

Square heatsink uses cold forging and pin fin design to enhance thermal performance

22September 2014, New Delhi, India – GlacialTech Inc., an experienced technology manufacturer, today launches a new cold forged heatsink for 60W LED thermal solutions– Igloo FS127. 

Pin Fin Design

123Using a pin-fin heatsink design for better airflow and surface area, the Igloo FS127 features a very efficient 0.89°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 ideal for lighting applications. A square heatsink shape accommodates square-type lighting fixture designs.

Low Thermal Resistance

12The 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 2.36times bettercompared 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.

GlacialTech’s Thermal Solutions
