Copper-Encased Vapor Chambers cool microprocessors.

Press Release Summary:



NanoSpreader Vapor Chambers are 2-phase chambers into which pure water is vacuum-sealed, absorbed by copper wick, and passed as vapor through micro-perforated copper sheet and returned as liquid to wick. Contained in packages from 1.5-70 mm, they attach directly to heat source and can cool power densities up to 150 W/cm2 while offering multidirectional thermal spreading as low as 0.02°C/W. Units can withstand clamping forces up to 90 psi and repeated exposure from -40 to +100°C.

Celsia Introduces Next Generation Heat Sink Technology, Furthering Its Goal of Replacing Heat Pipes in Computer, Telecommunications, and LED Lighting Applications



Heat Sinks Using Second Generation NanoSpreader Vapor Chambers Outperform Heat Pipe Solutions by 30 Percent

SAN JOSE, Calif., March 18 / / - 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.

Computer - Cooling the Latest Microprocessors

Whether it is a CPU used to power an entire computer or a special graphics processor (GPU) used by high end gamers or CAD designers, thermal requirements for cooling microprocessors are more demanding than ever before. Celsia's new NanoSpreaders can cool power densities up to 150 watts/cm2 while offering excellent multi-directional thermal spreading as low as 0.02 degrees 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 Environments

Equipment 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 degrees to +100 degrees Celsius.

LED Lighting - Effectively Dissipating Heat in Small Spaces

While 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.
