Based on CERN cooling technology, we created a pressure controlled phase change cooling system dedicated to cooling data centres. We use the power of 2-phase cooling to transport the heat in a much faster, and energy-efficient way. Unlike traditional cooling systems, we only target the problem areas (hot spots) without having to cool the whole infrastructure around it. By utilizing the unique properties of phase change, we can dissipate the excess heat of the computing units in a more direct, efficient way whilst creating an optimal thermal environment, ideal for processors with a high heat density.

What is the working principle?

It’s a 2-phase closed loop heat transfer system.  The loop is attached to a cold plate that is placed on top of the chip. The refrigerant starts its loop in liquid form at low temperature and is directed towards the chip via pump. Once it reaches the cold plate, it cools the chip by absorbing the excess heat through power of phase change – this is where it turns into vapour. The increase of the temperature due to excess heat turns the refrigerant into vapour/liquid mixture – this is allows to preserve the baseline temperature throughout the loop and maintain thermal stability.  The refrigerant continues its cycle towards the end of the loop where it releases of the excess heat via heat sink. This process transfers the refrigerant back to liquid form and the cycle starts again.
