Data centers are undergoing significant transformations as large artificial intelligence applications become more common. To meet the demands of high-density IT infrastructure, data centers are adopting innovative solutions, and one such technology is data center liquid cooling. This article explores the evolution of data center cooling, the advantages of liquid cooling, and its use cases across various industries.

Efficiency and Data Center Cooling:

Efficiency remains a key factor in managing data centers, ensuring maximum uptime while reducing operational costs. Identifying efficiency loopholes is crucial, especially as the IT infrastructure grows larger. New technologies are being introduced to stay ahead of the curve, and data center administrators are recognizing the importance of optimizing cooling systems to meet high-density demands.

The Road to Liquid Cooling

Data center cooling has evolved over the years, with efforts focused on enhancing efficiency and uptime. One popular technology is liquid cooling, which has evolved from a concept to a proven case study. Liquid cooling studies serve as fundamental references for implementing proper cooling practices.

Advancements in Data Center Cooling:

In the mid-1990s, hot and cold aisle organizations were introduced as a way to optimize server rack arrangements. In 2005, server cabinets with vertical exhausts demonstrated significant reductions in cooling energy costs. By 2006, data center airflow management shifted towards efficiency, leading to measurable energy savings. Over the years, air cooling technologies remained the standard, but they are starting to face limitations in supporting next-generation IT infrastructure.

In 2010 ASHRAE published documents focusing on the economization of cooling energy, ASHRAE 90.1 or the Energy Standard for Buildings. Additional stipulations include variable fan flow and humidity management. These became the reference for the new way of data center management.

From the 1990s to the mid-2000s, air cooling technologies were still the go-to option in data centers. For the longest time, raised floor systems have facilitated cold air movement to IT servers. Cooling the data center by cooling the air is still the standard solution up to this day.

The more significant issue to address is how air cooling can keep pace with next-generation IT infrastructure? Can an air-conditioned unit sustain hardware reliability? Can it maintain the correct temperature conditions for computer rooms? Air cooling is starting to reach it’s limitation and new technologies needed to be explored.

The Advent of Liquid Cooling

The necessity of removing heat from data centers is an ongoing concern to prevent equipment damage and downtime. Traditional air cooling has its downsides, such as particle and gas contamination, which can shorten equipment lifespan. Liquid cooling emerges as a direct alternative, offering higher efficiency levels, scalability, and optimization of server workload delivery.
