A thermally conductive fluid surrounds servers and removes heat efficiently, significantly enhancing cooling performance.
What is Immersion Cooling?
A next-generation method that improves energy efficiency and cooling performance in data centers.
Features of Immersion Cooling
Compared to traditional cooling methods such as air and water cooling, immersion cooling submerges the server directly in cooling fluid, effectively cooling the heat-generating components, thereby enhancing the cooling efficiency. Additionally, being non-conductive, it poses no risk of negatively impacting the server's electronic circuits.
Immersion Cooling Method
There are mainly two types of immersion cooling methods: "single-phase" and "two-phase."
| Single-Phase | Two-Phase | |
|---|---|---|
| Refrigerant | Hydrocarbon-based | Fluorinated |
| Features | Open System (cools while remaining liquid without phase change) |
Closed System (cools by using latent heat of vaporization) |

Mechanism of Single-Phase Immersion Cooling
The single-phase immersion cooling method cools by immersing servers in immersion racks filled with cooling fluid.After being heated by the servers, the fluid is circulated through a heat exchanger to cool the fluid then returned to cool the servers again.
