Data Centres

Data Centres account for 2% of global carbon emissions, a figure equal to that of air travel, with almost half of the energy consumed utilised for cooling.

An efficient cooling system is however, essential for a data centre, as thermal stress can directly impact performance, reducing throughput and reliability, and increasing the chance of electrostatic discharge, which may damage the equipment.

As the industry demands faster and smaller microprocessors, the pace of development for the production of more powerful chips has outstripped the capabilities of the traditional cooling systems used in Data Centres.

The conventional approach for achieving a higher rate of heat transfer in cooling systems is to increase surface areas and actively chill the coolants used. This is often impractical, as extra space is required to store larger data centre servers and racks, and increasing amounts of energy is consumed. A new nanofluid coolant with enhanced heat transport capabilities could not only significantly reduce the overall energy spend of data centres but provide more compact microprocessor drives, that will help to maximise the space available.

The NanoHex nanofluid will be applied to the cooling system of computer servers, racks and/or cabinets. Using a custom built cold plate, the coolant could be circulated through the data centre cabinets, adjacent to the server blades, in order to directly draw heat away from the processing chips. As several companies already use water as a coolant, there is a market for direct replacement, as well as a new cooling system.

The efficient removal of heat from computer servers, racks and cabinets would ease the demand for air conditioning in the server room decrease the size of chilling units and improve the performance of the system. All of which provide considerable cost savings. Such energy reductions and the re-cycling of heat captured by the coolant could help to cut carbon emissions and yield greater levels of efficiency and sustainability for the development of new manufacturing processes and products.
