Liquid immersion cooling

Liquid immersion cooling is a data center cooling method where IT equipment is submerged in a non-conductive, dielectric fluid. The fluid acts as a heat sink, drawing heat away from the equipment and dissipating it into the surrounding air.

This cooling method is highly efficient, as it eliminates the need for fans or other mechanical cooling devices. Additionally, it can be used in high-density data centers, where traditional air cooling methods are no longer effective.

Liquid immersion cooling is not without its challenges, however. The fluid must be carefully monitored and maintained, and the data center must be designed to accommodate the equipment and fluid. Additionally, this cooling method is not suitable for all types of IT equipment.

What liquid is used in immersion cooling?

There are a variety of different liquids that can be used for immersion cooling, depending on the specific needs of the data center. Some common choices include water, mineral oil, and dielectric fluids. Each of these has different benefits and drawbacks that should be considered when choosing a cooling solution.

Water is the most common choice for immersion cooling, as it is inexpensive and easy to work with. However, it is also a good conductor of heat, which can lead to problems if the data center overheats. Mineral oil is another popular choice, as it is non-conductive and has a high heat capacity. However, it is more expensive than water, and can be difficult to clean up if there is a spill.

Dielectric fluids are often used in high-performance data centers, as they are excellent at cooling and have a very low boiling point. However, they are also very expensive, and can be dangerous if they come into contact with skin or eyes. Is immersion cooling better? There is no one-size-fits-all answer to this question, as the best cooling solution for a data center depends on a variety of factors, including the size and layout of the facility, the types of equipment being used, the climate, and the budget. However, immersion cooling can offer a number of advantages over traditional air cooling, including improved cooling efficiency, lower noise levels, and reduced maintenance requirements.

Is immersion cooling efficient? Yes, immersion cooling is efficient. It is a very effective cooling method for data centers because it allows for direct contact between the heat-generating components and the coolant, which results in very efficient heat transfer. Additionally, immersion cooling can be used to cool components that generate a lot of heat, such as high-powered CPUs and GPUs, which would otherwise require a lot of cooling capacity.

Subsequently, what does immersion cooling do?

Immersion cooling is a method of cooling data center equipment by submerging it in a non-conductive fluid. This fluid can be either a dielectric fluid or a mineral oil. By submerging the equipment in the fluid, the heat generated by the equipment can be quickly dissipated, allowing the equipment to operate at a lower temperature.

Immersion cooling can provide a number of benefits for data center operators, including improved cooling efficiency, reduced energy consumption, and improved equipment reliability. In addition, immersion cooling can also allow for a smaller footprint for data center equipment, as the fluid can be used to fill the space between equipment racks.

While immersion cooling can offer many benefits, it is important to note that it is not a silver bullet solution for all data center cooling needs. In particular, immersion cooling is not well suited for equipment that generates a large amount of heat, such as high-end graphics processing units (GPUs). As such, it is important to evaluate the needs of a data center before deciding whether or not immersion cooling is the right solution.

Who invented immersion cooling?

Immersion cooling was first introduced in the early 2000s as a way to cool data center servers. The technology works by immersing servers in a dielectric fluid, which is a non-conductive liquid that can transfer heat away from the servers.

The first company to commercialize immersion cooling was Green Revolution Cooling, which was founded in 2007. Green Revolution Cooling introduced the first immersion-cooled data center in 2009.

Since then, a number of other companies have introduced their own immersion-cooled data centers, including Asetek, CoolIT Systems, and Submer.
