Immersion Cooling: Single-Phase vs. Phase-Change
Immersion cooling can be categorized as single-phase or phase-change, depending on whether the cooling liquid undergoes a phase transition during heat exchange.
In phase-change immersion cooling, servers or IT components are submerged in a dielectric coolant. The liquid absorbs heat, evaporates at low temperatures, and carries heat away from critical components. The vapor is then condensed (e.g., via condenser coils) and returned to the system as liquid.
Current studies suggest phase-change cooling may offer a slight efficiency edge over single-phase, with PUE values of 1.02 vs. 1.03, respectively.
Spray Cooling: Precision Chip-Level Thermal Management
Spray cooling represents an advanced direct-contact liquid cooling method that precisely targets chip-level components. Using gravity or system pressure, coolant is sprayed directly onto heat sources or their thermal interfaces, achieving 100% liquid contact.
While spray cooling's structural design offers revolutionary advantages over immersion cooling, its energy efficiency currently lags behind immersion methods. Both approaches share similar technical limitations despite their differing implementations.
Key Characteristics:
Direct, targeted cooling at component level
100% liquid contact efficiency
Structurally superior to immersion cooling
Lower energy efficiency than immersion solutions
Immersion Cooling Technologies: Single-Phase vs. Phase-Change
Immersion cooling systems are classified by their heat exchange mechanism:
Single-Phase Immersion Cooling
Coolant remains liquid throughout the process (no phase change)
Directly absorbs heat from submerged IT components
Transfers thermal energy via heat exchanger to cooling circuit
Delivers 100% liquid cooling with optimal energy efficiency
Features significantly lower maintenance requirements
Enables easier system access and component servicing
Phase-Change Immersion Cooling
Coolant undergoes liquid-to-vapor transition during operation
Provides enhanced heat transfer through latent heat absorption
Key Advantage: Single-phase systems currently lead in energy efficiency and operational simplicity, making them particularly suitable for data center applications where maintenance accessibility is crucial.
