Tech focus: Cooling

A round-up of the latest cooling technologies for scientists using HPC to support their research

As computing challenges increase, so too must the size of high performance computing systems, and this drives constraints to power usage and heat generation. Maintaining power efficiency requires innovative data centre and cooling design which can support these large HPC systems without compromising performance.

For computing applications such as complex weather models, simulations in automotive or mechanical engineering, animations in films, research analysis, or AI-based high-frequency trading of securities, HPC users require high performance cooling which can support their computing requirements.

In addition, companies are also increasingly using artificial intelligence applications to minimise the maintenance time of machines via machine learning in production environments.

Several different cooling technologies are available to HPC users, and these vary in performance in the amount of heat they can dissipate, cost and ease of maintenance, or upkeep costs. Rear Door heat exchangers (RDHX) rely on passive or active cooling in the server door, which can help to reduce cabinet temperatures and better control the overall temperature of the server rack.

Liquid cooling is in theory very similar to using air but instead, liquid is pumped in a closed system. Water has a better thermal conductivity, so this is potentially a higher performance system but requires additional infrastructure. Water-cooled data centres may also require additional costs from raised flooring or other infrastructure to support the water pipes and other equipment. Immersion cooling solutions use a non-conductive liquid that can sit directly alongside components. As the liquid heats up, it circulates and moves away from the hot components, creating a flow that keeps the component cool.

With the global race to deliver the HPC industry’s next supercomputing milestone gathering pace, there is possibly little surprise that innovation within the cooling market for HPCs/data centres has likewise stepped up a gear, as the efficiency and performance of cooling technology becomes ever more significant in preventing the operational costs of HPC resources from reaching prohibitive levels.

Featured product: Nortek Data Center Cooling 

Data centre professionals looking to build the next big thing, need a cooling system that can keep up. Nortek Data Center Cooling StatePoint Indirect Cooling Technology brings reliability and optimum performance to any data centre, regardless of location or climate.

This revolutionary technology delivers a solution that is better for business and the environment. StatePoint uses an indirect evaporative cooling method with a unique semi-permeable membrane exchanger that completely separates water from the air stream to prevent cross contamination. The result – significant power and water savings (as much as 30 per cent) and minimised risk for biological growths, such as Legionella.

StatePoint easily integrates with a variety of systems to offer a complete cooling solution. The unit can use recycled water, interface with waste heat recovery systems and operate off wind and solar power to help data centres take the next step toward net-zero operation.

Featured product: CPC’s Everis 

Getting top liquid cooling performance with CPC’s Everis purpose-built quick disconnects

As heat generated by HPC increases, use of liquid cooling becomes necessary to dissipate the heat and help ensure system performance. Use of quick disconnects (QDs) or quick-release couplings that are specifically designed and manufactured for liquid cooling of electronics applications, is the way to achieve cooling targets and reliable optimal ongoing operation. CPC’s Everis line of QDs are built for liquid cooling.

All Everis QDs are non-spill and they feature superior flow to size ratios and redundant multi-lobed seals. Everis quick connects are available in a wide array of styles, materials, terminations, and sizes to match cooling load demands, coolant selection and system configuration. Additionally, CPC liquid cooling application engineers are available to answer questions about the wetted loop and QD impact to flow and pressure. Ultimately, CPC understands the holistic nature of liquid cooling. Contact us.
