How to choose a liquid cooling solution for high rack power density?

When selecting a liquid cooling solution for high rack power densities and improved eficiency, several factors should be considered, including ease of adoption, deployment cost, reliability, eficiency, and sustainability. Based on these factors, two-phase direct on-chip liquid cooling is the optimum liquid cooling method.

Why do data centers need a liquid cooling system?

By integrating advanced liquid cooling technology with advanced cabinet systems, densely configured racks can support higher core counts and workloads, allowing data centers to utilize real estate more eficiently.

Can liquid cooling cool equipment with a CPU power of 400W?

Only liquid cooling can cool equipment with a CPU power of 400W or higher. Figure 1: Transition from air cooling to liquid cooling based on CPU power and ASHRAE air-cooled and liquid-cooled classes for equipment operation. Source: ASHRAE

What is liquid cooling technology?

Liquid cooling technology has emerged as an eficient solution to address these challenges, removing heat more effectively than air to enable higher power densities and improved sustainability.

How do data centers manage heat?

Traditional air-based cooling methods, such as hot aisle/cold aisle configurations and containment solutions like cold aisle containment (CAC), hot aisle containment (HAC), and vertical exhaust ducts (VED), have been effective in managing heat in data centers with lower power densities.

How does a coolant distribution unit work?

This solution involves using liquid-filled coils in the rear door of the cabinet, where hot exhaust air from the equipment passes through the coils and is returned to the room at ambient temperature. The heated liquid is returned to the Coolant Distribution Unit where it is cooled typically via a chilled water loop and pumped back through the coil.
