Spray cooling to lower carbon footprint for data centres



Nanyang Technological University (NTU) scientists in Singapore say they have developed a far more sustainable and environmentally friendly system for cooling down servers in knowledge centres, likely decreasing both electricity expenses and carbon footprint by up to 26 per cent.

Knowledge centres in Singapore at this time account for 7 for each cent of the nation’s total electricity consumption. With need for cloud computing increasing, a sustainable remedy is necessary to minimize the country’s electricity consumption and carbon footprint.

In a data centre the hottest part in a server is the central processing unit (CPU), which involves a committed air-cooled heatsink. Thw information centre also desires to be cooled by reduced temperature air conditioning.

The new approach formulated by the NTU experts works by using a special spray of non-conductive fluids to great the CPU straight with no a heatsink. Additionally, a closed-loop system is created to accumulate the fluids and amazing them in tropical ambient air temperature with out the need to have of a chiller or air conditioning.

“This will also permit CPUs to operate a lot quicker and accomplish much better than today’s speeds, which are restricted by air cooling, because quicker speeds currently lead to better temperatures,” the scientists say.

“As spray-cooling has a higher warmth rejection capability, it is estimated it will also require 30 per cent significantly less space than a typical air-cooled facts centre.”
