What is Two Phase Immersion Cooling?

How the Two phase Immersion Cooling Cycle Works


Two-phase Immersion cooling is a new type of cooling technology for data centers. When it comes to two-phase commercial immersion cooling, E3 is one of the few names in the industry. In a two-phase immersion-cooled system, electronic components are immersed in a bath of dielectric heat-transfer fluids, which conduct heat much better than air, water, or low-boiling-point oil (i.49°C vs. 100 °C in water) liquids boil on the surface of heat-generating components and rising steam ensures passive heat transfer. It's this simplicity that eliminates traditional cooling hardware and results in better cooling efficiency. Compared to conventional air, water or oil cooling, this passive process consumes much less energy.


This essentially means that the liquid used changes state. During this change of state, it carries heat in gaseous form to the top of the tank. A condensing coil cools the gas and it rains back into the immersion tank as a liquid to start the process over. Two-phase immersion cooling is the most promising method of all cooling solutions. The cooling energy consumption can be reduced by 95%. While air solutions have power densities between 4 and 40 kW per rack, two-phase solutions can achieve up to 250 kW per rack. Generating PUE values ​​of 1.02-1.

03, close to the global minimum and previously only achieved with free-cooling solutions from large IT companies. The advantage over air method is that it is geographically independent, which is crucial for EC solutions. This strategy is also space-saving, taking up ten times less space than air solutions (100 kW/m2 compared to 10 kW/m2). This space saving is also enormous for EDC use. Therefore, it can adapt better than other water or dielectric liquid solutions. The coolant recirculation method is key to achieving excellent space and energy efficiency [39]. The aim is to get the liquid to flow passively (i.e. without using electricity) by boiling and condensing using high operating temperatures (above 60 °C). During operation, electronic equipment immersed in a closed bath evaporates the liquid. The fluids vapor then rises to the top, where a heat exchanger condenses it back into the liquid phase. The heat exchanger placed inside the immersion tank circulates the water and sends it to a dry cooler where it is cooled. This part is the only source of energy consumption in this method and it is almost zero since the operating temperatures of the water and liquid are the highest among cooling solutions.

Two-Phase Immersion Cooling is the perfect solution for high-density applications like blockchain, HPC, Deep Learning, Edge Computing and Cryptocurrency mining (Bitcoin, Ethereum, Ripple, Litecoin, etc.) using any ASIC or GPU hardware.
