Celsia introduces next generation heat sink technology for LED lighting

Date Announced: 19 Mar 2008 SAN JOSE, California -– Already credited with making vapor chambers (a once exotic heat sink technology) thin, light and affordable, Celsia Technologies (“Celsia”) today introduces its second generation NanoSpreader. Thermal transfer properties from the heat source to the vapor have been improved by 66 percent over the first generation, using a re-engineered internal structure that leverages the company’s patented combination of copper, liquid and vapor. These changes, developed through extensive collaboration with industry-leading computing and graphics manufacturers, give the new NanoSpreader the ability to trump heat pipes as the king of cost-effective cooling.“While maintaining reliability standards and manufacturing costs, our engineers have designed this next generation product to offer up to 30 percent better thermal performance than solutions using traditional heat pipes, and their design flexibility allows them to be used in some unexpected ways,” said Joe Formichelli, Celsia’s CEO. “For instance, a single NanoSpreader can be made up to 70mm wide and attach directly to the heat source, eliminating the need for additional components while completely covering even a very large hot spot.” Nanospreaders are patented copper encased two-phase vapor chambers into which pure water is vacuum sealed. The liquid is absorbed by a copper wick and passed as vapor through a micro-perforated copper sheet where it cools and returns as liquid to the wick. The latest generation technology is ideally suited for solving some of today’s biggest thermal challenges: cooling the latest microprocessors, reliably operating in harsh environments, and effectively dissipating heat in small spaces.

Celsia’s new NanoSpreaders can cool power densities up to 150 watts/cm2 while offering excellent multi-directional thermal spreading as low as 0.02o Celsius per watt. Additionally, NanoSpreaders can withstand clamping forces up to 90 PSI, giving thermal designers the option of attaching them directly to the CPU/GPU. Telecommunications Infrastructure - Reliably Operating in Harsh EnvironmentsEquipment that operates as part of the telecommunication backbone (such as repeaters and base stations) must be reliable in some of the harshest weather imaginable. With no moving parts, Celsia NanoSpreaders are designed and tested to withstand repeated exposure of -40 o to +100 o Celsius. LED Lighting - Effectively Dissipating Heat in Small SpacesWhile LED lighting technology is quickly offering an energy efficient alternative to other lighting technologies, it requires cooling solutions that are effective in small areas. The efficiency of Celsia’s NanoSpreaders combined into a remarkably thin package (from 1.5mm) allows lighting designs with higher lumens/watt.For more information on Celsia or the technical details behind NanoSpreaders please visit Celsiatechnologies.com. A downloadable fact sheet describes the technology, lists 21 standard sizes, and includes information on thermal resistance and reliability testing.
