Witryna24 lut 2024 · The two-phase immersion cooling system is relatively similar but sees servers sealed in an engineered fluorocarbon-based liquid. Unlike single-phase, the fluid can boil even before reaching 50°C. The heat generated from the servers boils the surrounding fluid to change its state from liquid to gas. The resulting vapor is changed …
