By using these methods, you can save energy and money. This also helps the environment. As data centers grow, energy-efficient cooling will be even more important for success.

Common Server Cooling Methods

Air Cooling Systems and Their Uses

Air cooling is the oldest and most common way to cool servers. It uses fans to move air and remove heat from servers. This method is cheap and simple, so it works well for small or medium data centers. But as servers get packed closer together, air cooling becomes less useful. When racks use more than 20kW of power, air cooling struggles. This can lead to higher energy bills and more costs.

To make air cooling better, you can try some tricks. One trick is using hot-aisle/cold-aisle setups. This keeps hot and cold air apart, making cooling work better. Another trick is adding blanking panels to racks. These panels stop air from mixing, which helps cooling. Air cooling is still a good choice for many, but it doesn’t work well for very crowded server setups. That’s why people are trying newer cooling methods.

Liquid Cooling for Crowded Data Centers

Liquid cooling is a smarter way to cool busy data centers. It uses water or special liquids to take heat away from servers. This method cools better than air and allows more servers in one rack. Big companies like Meta and Google use liquid cooling for AI and other tough tasks.

One popular system is the closed-loop chilled water system. It saves electricity and doesn’t waste water, making it eco-friendly. Liquid cooling also lowers Power Usage Effectiveness (PUE), which measures energy efficiency. Most data centers have a PUE of 1.8, but liquid cooling can lower it to 1.2 or even 1.036. This shows how well it works.

Liquid cooling not only makes servers work better but also helps the environment. This makes it a top choice for today’s data centers.

Immersion Cooling: A New Way to Cool

Immersion cooling is a cutting-edge method where servers are placed in a special liquid. This liquid doesn’t conduct electricity, so it’s safe for servers. It removes the need for fans and other cooling tools. Immersion cooling works well for very crowded racks, making it great for AI, virtual reality, and self-driving cars.

Companies like GRC are leading in immersion cooling. GRC got $28 million to improve this technology. They also work with Intel and HPE to make it even better. Immersion cooling has fewer moving parts, so it breaks down less often and is more reliable.

As data centers grow, immersion cooling offers a smart and eco-friendly way to handle the heat. It’s a strong choice for the future.

Hybrid Cooling Systems for Better Performance

Hybrid cooling systems mix different cooling methods for better results. They often combine air and liquid cooling or use advanced systems like Hybrid Dry/Adiabatic Cooling (HDAC). These systems adjust to changes and save energy.

A big benefit of hybrid systems is their energy efficiency. For example:

• HDAC systems can have a Power Usage Effectiveness (PUE) of 1.05 to 1.062.

• Older cooling methods, like direct adiabatic cooling, usually have a PUE above 1.20.

This lower PUE means hybrid systems use less energy. This saves money and helps the environment.

Another advantage is saving water. In mid-Atlantic areas, HDAC systems don’t use water for about 94% of the year. This makes them better than cooling towers, which need a lot of water.

Tip: If your data center is in a dry area, hybrid systems can cut water use while keeping servers cool.

Hybrid systems are also flexible. They handle different workloads and weather conditions. For example, air cooling works well in cooler months. Liquid cooling helps during hot times. This reduces wasted energy and keeps servers steady.

Using hybrid cooling balances performance, energy savings, and sustainability. It’s a smart choice for future data center needs.
