GlacialTech expands its round LED heatsink series with new models from 5- 21cm diameter. They are designed to be optimized for CoB or metal core PCB (MPCB) applications through the power of cold forging design.
The CoB applications use a thicker, 7- 10mm base to address the specific heating needs of new LED Technology. CoB LEDs uses LEDs mounted directly to the board to create brighter, more uniform and more efficient LED light sources, but all those LEDs in a small space generate tons of heat in a small area.
The heat dissipation has a thicker base and is spread over a larger area for the heatsink for effective operation. GlacialTech’s 7mm and 10mm base heatsinks take care of this performance issue to cool CoB LEDs more effectively.
For MPCB applications, the heatsinks use a thinner 5mm base for more efficient cooling, which already have good horizontal heat spreading characteristics.
Metal cores PCB (MPCB) LEDs are designed by keeping thermal management in mind, with a low thermal resistance to dissipate heat over a horizontal surface area.
Hence, the new MPCB heatsinks use a thinner base to raise heat to the fins, improving heating efficiency for this type of LED.
With these new models, GlacialTech now offers 11 cold forged heatsinks from 5cm to 21cm diameter. Sizes are 5cm, 7cm, 8cm, 9cm, 10cm, 11cm, 12cm, 13cm, 15cm, 16cm, and 21cm to fit a variety of LED lighting fixtures.
The cold forged process means these heatsinks perform better than traditional die cast heatsinks and come in a one piece design for easy assembly.
