Miniaturization of electronic products is to reach its limits, partly because of thermal management. Many have now solved this problem in actively trying. One approach being explored is the LED reverse run.
Look for more effective ways to cool computer, almost eager to find better battery chemistry, as in the research agenda of the scientists are also at an important position.
More crucial to the cooling means to reduce costs. Cooling technology also makes possible a more powerful processing in a smaller space, which is limited processing power should be calculated not waste heat. Cooling technology can prevent the failure due to heat, thus extending the service life of components, and can promote environmentally friendly data center - less heat means less impact on the environment.
How to remove heat from the microprocessor is in a direction scientists have been exploring, they thought they had made a simple and unusual and counterintuitive solution. They say they can run a light emitting diode (LED), a variant, it may force the electrode inversion element behaves like in the same work at extremely low temperatures. If placed next to the hotter the electronic device, and then introduced into a nanoscale gap, the LED may absorb heat.
"Once the reverse bias LED, it will be like a very cold objects, like the absorption of photons," Professor of Mechanical Engineering at the University of Michigan Edgar Meihuo Fu announced the breakthrough of the press release said. "Meanwhile, the gap prevents heat returns, thereby producing a cooling effect."
Researchers say, LED and adjacent electronic device (in this case calorimeter, usually used to measure thermal energy) must be very close. They say they have been able to prove that reached 6 watts per square meter cooling power. They explained that this is almost the Earth's surface energy of sunlight received.
Internet of Things (IoT) and smartphones may be the ultimate electronic products will benefit from this LED transformation. Both devices need to accommodate more computing power in a smaller space.
"Microprocessor that can be removed from the heat began to limit sodium content in a given space power," said University of Michigan announcement.
Materials science and computer cooling
I've written about new forms of computer cooling before . Foreign material from materials science is one of the ideas being explored. US Department of Energy's Lawrence Berkeley National Laboratory, said sodium bismuth (Na3Bi) can be used in transistor design. The new charged species, important to have an adjustable resistance; however, it need not be cooled like that superconductor.
In fact, this is a problem superconductors. Unfortunately, they require more cooling than most electronic devices - eliminating the resistance by extreme cooling.
In addition, German researchers at the University of Konstanz said they will soon have computer-driven superconductor, there is no waste heat. They plan to use the electron spin - a new electronic physical dimensions, can improve efficiency. Last year, the university said in a press release that this approach "significantly reduces energy consumption Jisuanzhongxin of."
Another method of reducing heat may be used in embedded microprocessor helical and loop to replace the traditional heat sink . Scientists at the University of Dayton Bingham said India tiny channels on the chip can provide a separate channel for the coolant.
University of Konstanz said: "The miniaturization of semiconductor technology is approaching its physical limits." Thermal management is now scientists put on the agenda. This is the "miniaturization of a challenge."
