At Incooling we have designed a cooling system by adapting the unique properties of phase change cooling. 

Incooling SVC is a compressor-based cooling system aimed at cooling high-performance servers, unlike the traditional cooling systems, it directly focuses on their main heat source: the CPU.  

It is a fully independent closed-loop system that can be inserted directly in your server. With our proprietary control system, we are able to quickly respond to the fluctuating heat loads, adjusting itself to maintain the processor always within safe temperature ranges.

Together with the unique properties of phase change cooling and a proprietary thermal control system, we can achieve:

  • Up to 65% performance increase in clock speed (compared to base frequency)
  • Support heat loads up to 400 W
  • Up to 50% more efficient compared to AIO water cooling
  • No leakage, corrosion, bio-growth risk.
  • 95000h Mean Time Between Failures (MTBF) on critical components

By achieving temperature stability that is efficient and reliable we enable your server to achieve its full potential.

What is 2-phase (phase change) cooling?

What is 2 phase cooling?

When temperature changes, the matter can undergo a phase change, shifting from one form to another. Few examples of phase change are melting (changing from a solid to a liquid), freezing (changing from a liquid to a solid), evaporation (changing from a liquid to a gas), and condensation (changing from a gas to a liquid). In a 2-phase cooling system, the refrigerant (also known as coolant) is not only heated, but it is also subjected to phase change. This means that when the refrigerant is heated until its boiling point, it will transform from a liquid state into a gas state (or vapour) the same process as when boiling water. In order to change phase, it requires a large amount of heat known as latent heat. This is beneficial in a cooling system as it allows to absorb more heat. It is also good to know that the temperature remains constant when changing phase, meaning that it will take longer for the cooling system to heat up.

Working Principle 

Incooling develops a 2 phase, pressure controlled, closed-loop heat transfer system. In other words, a cooling system. Its goal is to enhance cooling performance by directly cooling chips instead of cooling the air around the chip or server. This is done by attaching an evaporator (cold plate) directly on top of the chip. The cold plate is a device which extracts heat by transferring this heat to a refrigerant (also known as coolant).


The two-phase refrigerant cycles through a looped cooling system. The refrigerant starts its loop in a liquid phase at low temperature and is directed towards the chip via the pump. Once it reaches the cold plate, it cools the chip by absorbing the excess heat; this is where it turns into vapour. The increase of the temperature, due to excess heat, turns the refrigerant into vapour/liquid mixture. This preserves the baseline temperature throughout the loop and maintains thermal stability. The refrigerant continues its cycle towards the end of the loop where it releases the excess heat through the condenser. This process transfers the refrigerant back to liquid form, and the cycle starts again. The benefit of this system is that it is able to absorb more heat while operating at a smaller, and usually lower, temperature range. It is, therefore, outperforming air cooling or traditional water cooling.
