Today, most PCs have a cooling technology that involves a computer cooling fan and a cooling device. Yet powerful CPUs that have TDP of 100 watts are becoming more and more popular and air-cooling technology is not that good any more. Liquid cooling may seem a perfect solution as a thermally conductive material transfers heat from a warm component to the liquid in the tube. The liquid then moves to the actual cooling device that absorbs the heat from the liquid. The liquid loops back around and continuously repeats this process keeping the desktop at a cool temperature to perform at its peak level. The SPbU students have come up with an idea as to how to reduce the noise and power consumption.

“Liquid cooling is at the core of our invention. The heat is transferred by electrodynamic currents, — said Albert Gazarian, the leader of the team and a graduate student at SPbU. — The currents are generated when the electrodes in the liquid dielectrics (say, oil) are exposed to high voltage in the strong electric field. The ionic liquid transfers the heat”.

The system involves three elements: an electromagnetic pump, a mixer, and a cooling device. The first element moves the liquid to the mixer where the heat is transferred from the CPU. The dielectric, when heated, moves to the radiator to cool and loop back again.

The invention will reduce power consumption as low currents flow through the liquid dielectric. The system doesn’t involve mechanical parts that should be replaced when damaged or worn. Liquid-cooled systems therefore tend to be whisper quiet, sometimes completely silent, and can work indefinitely. Unlike the ordinary liquid cooling systems, this technology is rather simple and value-for-money.

Today, more and more technical items are produced for data centres and gaming computers. These machines produce more heat as they are more powerful. The cooling solutions we have now cannot prevent them from overheating. We are sure that our invention will be very much needed. It will be available to anyone and you will be able to buy for your home PC.

The students are planning to cooperate with the manufacturers, so that the cooling system would be installed in the machines when they are produced. By the end of May, they are planning to finish constructing the prototype model.

Apart from Albert Gazarian, the team comprises Sergei Vasilkov, an aspirantura student in Physics and Astronomy, Andrei Kalinichev, an aspirantura student in Chemical Sciences, Dmitrii Komarov, a graduate student in Applied Mathematics and Physics, and Anna Grishkina, an aspirantura student in Economics.  The scientific supervisor is Candidate of Physics and Mathematics and SPbU Associate Professor Vladimir Chirkov.
