With the goal to have current energy-saving and eco-friendly system to develop high performance computers and data centers, Aquasar uses a closed water system for heat transfer and cooling system at the same time.
"Aquasar consumes up to 40 percent less energy than a comparable air-cooled machine and the CO2 balance of the computer can be significantly improved through the direct use of waste heat can the system emissions by up to 85 percent reduction," said Professor Dimos Poulikakos, Project Manager and Head of the Laboratory of Thermodynamics in New Technologies at ETHZ to the Kuwait News Agency (KUNA).
"With Aquasar, we make an important contribution to the development of sustainable high performance computers and computer systems. In the future, it will be as crucial as a powerful computer per watt and per gram of CO2," he added.
Liquid cooling, however, is far more effective, Poulikakos said, explaining "the water has about 4,000 times higher heat capacity than air and can therefore transport heat very efficiently." This allows new cooling concepts - such as the cooling of hot water - both from an economic and environmental point of view sustainable.
In total, the system achieves an output of about six teraflops and consumes about 20 kilowatts.
Intelligent cooling circuit with up to 60 degrees Celsius are the processors and other components cooled in the new high-performance computers.
The entire cooling system of the computer is a closed, hermetically sealed cycle, using a pump with a rate of 30 liters. The wast heat through a heat exchanger is re-directed to an external secondary circuit disclosed in the case of (Aquasar) to the heating system building at ETHZ.
To cool with hot water, thus combines two advantages; no energy-intensive refrigeration needed and energy consumption significantly reduced. (end) ta.hb KUNA 071819 May 10NNNN
