Yet, Silent CPU Fan is only a research project – but one that has already been licensed to a major manufacturer of cooling systems for computers. General Electric is moving air without rotors using piezoelectric.
It looks at first glance like a Peltier element , one of the well-functioning cooling method for processors which could never prevail in the mass market – but 3 mm Flat GE Jet Cooler specified device works quite differently. What the pictures show the company is a replacement for the fan, not the entire cooling solution in a notebook requires even heat-pipes.
Rather than wishing on rotating blades to extract the new air from round the natural philosophy, the device developed as GE world analysis uses vibrations generated by a electricity material. The device, that has been dubbed the “dual piezo cooling jet,” measures simply 3 millimeters thick.
The jet cooler consists of two metal plates between which there is a special ceramic. This material has piezoelectric properties: When a voltage it changes shape. The reverse effect is known from the so-called electronic lighters. These is by deforming a piezoelectric element – that is, the pressure on the ignition button – rele
Only the air ducts for supply and exhaust air must be designed differently than before, because most of these designs start from a fan that draws in fresh air over a large area. When the Jet Cool is only a millimeter thin slit.
Two big advantages result from the technology, according to GE: First, the electric blower is very thin for a notebook should already be enough 3 millimeters. Second, to the Jet Cooler be so low that the user can barely hear its sound.
The analysis team, diode by GE international Research’s lead thermal systems engineer, Peter deBock, has already swapped their device for an exponent in an exceedingly portable computer.
“We had plenty of house left over,” deBock says. “It will create the portable computer agent or enable adding additional physics.”
Still, there is no freely available products with the technology, but that could soon change: GE has awarded Jet Cool license to the Japanese company Fujikura which is manufactures of cooling solutions.
