Redefining High-Density Thermal Management



Immersion Cooling Overview



ThermInfra’s Single-Phase Immersion Cooling Solution provides an end-to-end architecture engineered to cool the most demanding high-density workloads. By totally submerging servers in specially formulated dielectric fluid, heat is directly captured from critical components and efficiently rejected through our advanced closed-loop system.

End-to-End Architecture Workflow

A step-by-step breakdown of heat extraction and rejection.

1. Chip Level

Heat generated at the chip is transferred directly to dielectric coolant.

2. Immersion Tank

Servers fully submerged in single-phase dielectric coolant.

3. Immersion CDU

Compact CDU placed close to tank for efficient flow & control.

4. Facility Loop

(Glycol/Water) Transfers heat from CDU to external dry cooler.

5. Heat Rejection

Dry cooler rejects accumulated heat directly to ambient air.

6. Controls

Intelligent controls for safe, efficient, and reliable operation.

Immersion Tank

Single-Phase Dielectric Coolant & Tank

Designed for optimal thermal transfer and total server submersion without the risk of electrical shorting or component degradation.

  • Non-conductive & Safe: Prevents electrical shorts and extends hardware life.
  • High Thermal Performance: Captures 100% of heat directly from processors and components.
  • Long Fluid Life: Formulated for extended operation without fluid degradation.
  • No Server Fans Required: Completely eliminates power-hungry server fans.
Cooling Distribution Unit

Compact & Efficient CDU

The Cooling Distribution Unit (CDU) manages system pressure, flow rates, and heat exchange between the primary dielectric fluid loop and the facility loop.

  • Integrated high-efficiency pumps, filtration, heat exchangers, and controls.
  • Small footprint designed to sit directly adjacent to the immersion tank.
  • Precision-regulated fluid flow for optimal thermal balance.
Dry Cooler Heat Rejection

Dry Cooler & Facility Loop Heat Rejection

A closed-loop system circulating a water/glycol mixture transfers heat from the CDU heat exchanger out to the dry cooling units.

  • Water-Saving Operation: Rejects heat to ambient air with high energy efficiency.
  • Corrosion Protection: Infused with corrosion inhibitors for continuous durability.
  • Reliable & Low Maintenance: Engineered for continuous 24/7 industrial execution.
