Small may be beautiful, but when it comes to home electronic devices, small also needs to be cool. As electronics companies try to meet consumer demand for smaller and more compact laptops, MP3 players, cameras and gaming consoles, they’re also working hard to prevent the devices from over- heating.
The consumer may want smaller devices that offer more and more powerful functions – but there’s a risk their newly acquired high powered devices like laptops will get too hot, causing circuits to melt and the hardware to fail.
The computing power of electronics devices are doubling almost every year. While today’s laptops are shrinking to almost the thickness of an envelope, their increasing processing power and capacity generates a large amount of heat. Research by Slava Rotkin, Professor of Sciences at Lehigh University, USA, indicates that a laptop generates heat faster when in use than an everyday hotplate and almost as fast as a small nuclear reactor.
The growing use of High Brightness Light — Emitting Diodes (HBLEDs) for backlighting in mobile phones, and for LCD’s in television sets, flat panel displays and computer screens adds to the heat problem.
Dow Corning has developed a range of specialized thermally conductive materials and heat transfer materials to help manufacturers deal with the issue. These materials, in the form of adhesives, encapsulants, compounds, gels and pads, prolong the life of the electronic devices by protecting their sensitive circuits and components and enabling the excess heat to be carried off and dissipated.
Dow Corning offers a variety of silicones that function as heat transfer media, provide remarkable thermal conductivity, electrical insulation, moisture and UV resistance and protect the most sensitive electronic assemblies from corrosion, environmental contamination and external vibrations.
