Graphite providing electronic cooling

Graphite providing electronic cooling

New findings indicate that graphene offers efficient electronic cooling, reducing the operating temperature of up to 25% within the processor hotspots.

Led international research team at Chalmers University of Technology, Sweden, in the world, is the first to show that graphene has a cooling effect on the silicon electronics. The research team found that a layer of graphite, can reduce the operating temperature of the hot spot inside the processor up to 25% - this can significantly extend the computers and other electronic products working life.

â € œThis discovery opens the door to increased functionality, and continue to push the boundaries when it comes to miniaturization of electronic products, â €? Chalmers international research project led by Professor John Liu said.

Modern electronic systems generate a lot of heat, above all the increasing demand for more and more features. It is important to be able to remove the heat generated in an efficient way to maintain long life of the system. A rule of thumb is 10 degrees Celsius operating temperature rises, the working life of electronic systems halved.

In this study, the researchers focused on electronic most intensive work - such as the processor, for example in a small range of temperature. These tiny hot spots are found in all electronic products. Size wise, they are a micro or nano-scale, in other words thousandth of a millimeter or less.

â € œThe graphene layer that has cooled the hot, our normal working temperature from 55 to 115 degrees Celsius. We have been able to reduce up to 13 degrees, which not only improves the efficiency of energy use, but also to extend the working life of electronics.â €?

Efficient cooling is a major challenge in many different applications, such as automotive electronics, power electronics, computers, wireless base stations and a variety of light-emitting diode, or LED lights. In the ignition system in the automotive electronic systems, no single device can pump out up to 80 W continuous and up to 300 watts (10 nanoseconds) in transient phase. LED device can have a hot strength compared with the sun is almost up to 600 W/cm2, due to their small size.

Advanced electronic cooling can provide a huge advantage. According to a recent study, based on data from 2006, approximately 50% of total electricity consumption data server to run the cooling system.
