to cold plates. The heat is then rejected out of the unit into the hot aisle as air; this rejection of heat is where LTA systems get their name.
Deploying liquid cooling without relying on facility water offers significant advantages, such as avoiding the complexities of facility water infrastructure and reducing operational costs. This approach allows data centres to leverage alternative cooling solutions while maintaining high performance and reliability. However, in order for data centre managers to realise these benefits, they need to make sure their LTA systems are designed to succeed.
Reducing operational costs and scaling HPC workloads
An LTA system allows the end-user to stack racks with more density compared to a solely air-cooled rack. LTA systems can help reduce costs for data centres by compressing racks together and increasing chip density, as well as helping to bring in additional revenue by supporting more chips. Using the power of liquid cooling, data centres can power and cool more chips while managing their energy use and physical footprint. For colocation( colo) data centres in particular, this can be a critical technology, as they are able to establish high-performance computing and AI clusters within their data centres. This allows colo data centres
to support AI and high-performance computing for some clients without disrupting existing business.
As long as LTA components have features that are conducive to modular design, LTA systems are very scalable. This enables easy expansion as cooling demands grow since additional LTA units can be added to racks as needed.
Sustainability
Liquid cooled chips reject heat more efficiently than air because of the greater heat transfer capacity of liquid compared to air. Engineers can also design cooling systems with liquid that bring the thermal carrying medium closer to the heat source. While LTA systems may not offer as much overall power efficiency as fully liquid-to-liquid devices, they can still drive sustainability in several areas.
First, the liquid in LTA systems is circulated in a closed loop. This system brings the liquid loop close to IT equipment, requiring less energy to distribute the fluid over long distances. Additionally, while water needs to be filtered to maintain quality and occasionally be replaced, LTA systems do not need a constant supply of fresh water. This can help data centres conserve water in addition to using energy efficiently.
