The classic layout of the air cooling system chipset is not changed for decades: a radiator mounted on a stationary fan blades that blow in the rotation fins, removing heat from them. Meanwhile, members of the U.S. Sandia Laboratory have developed a cooler, which performs the role of the fan … rotating at several thousand revolutions per minute, the radiator!

Fins act as the impeller, which creates air movement. Along the way, this arrangement solves the problem with the accumulation of dust on the fins – as they always rotate the dust settle on them do not have time. But what about connecting a rotating radiator with a fixed base cooler? The developers propose to use the gas-dynamic bearing – aluminum flat ground between the cooler and radiator support sole rotating air gap less than 0.03 mm. Something similar can be observed in hard disk drives, the head which glides over the surface of a magnetic plate or in a desktop air hockey – “Puck” flies over the surface of the table without the slightest resistance.

To eliminate the dependence on gravity and the orientation of the cooler space, the rotating part of the radiator is pressed to a fixed base of the spring, but the magnitude of the gap continuously monitors the sensor. Such a small air gap between the links of the chain of heat, according to developers, does not impair the efficiency of heat transfer between them. The thermal resistance of this innovative cooler is 0.2 degrees per watt, whereas the traditional layout for the coolers, the figure is 0.6-0.8 degrees per watt. In addition to high efficiency and resistance to dusting, the cooling system has another advantage – a relatively modest dimensions. This quality allows the use of such coolers to laptops, and server solutions. The developers are open to cooperation with companies willing to use a patented design for mass-produced cooling systems.
