Why Two-Phase

Why 2kW–3kW Processors
Require Two-Phase Cooling

Single-phase water cooling has no absolute heat dissipation limit, but in practice it can only mitigate the issue by narrowing microchannels and increasing flow rate—at the cost of excessive pumping power, pipe erosion, and drastically reduced filter lifespan. Moving to two-phase flow is the more practical solution.

Limitations of Single-Phase Water Cooling

  • Relies on sensible heat temperature rise—as heat flux climbs, the only answer is blindly increasing flow rate
  • High-pressure, high-flow operation causes severe pipe erosion and noise
  • Drastically shortened filter lifespan and excessive pumping power
  • Any water leakage directly causes short circuits and burnout in IT equipment

How Two-Phase Flow Cooling (PTPC) Solves It

  • Uses phase-change latent heat instead of sensible heat—the required flow rate is far below single-phase
  • Dramatically lower flow rate → pumping power is only about 1/6 of single-phase
  • Coolant leaves the cold plate 100% vaporized—every drop of liquid becomes heat dissipation capacity
  • Uses dielectric coolant—even leakage cannot cause short circuits, completely avoiding the erosion ceiling
Core Advantages

Four Key Physical Advantages
of Two-Phase Flow

≈0°C

Excellent Isothermality

The coolant maintains a constant saturation temperature throughout the phase change, ensuring uniform cold plate surface temperature and significantly reducing silicon chip warpage.

1/6

Extremely Low Pumping Power

By utilizing vaporization latent heat, the required flow rate is far below single-phase water cooling; when handling extreme heat flux, pumping power is roughly six times lower than a single-phase system.

100%

Complete Vaporization Efficiency

Advanced cold plate design enables the coolant to fully vaporize as it exits—every drop of liquid coolant the pump delivers is perfectly converted into heat dissipation capacity.

0 Short Circuits

Electrical Insulation Protection

Using dielectric coolant, even in the event of leakage, IT equipment is protected from short-circuit burnout—fundamentally improving data center reliability.

Live Demo Unit · Actual Footage

Not Just Theory—
Our Air-Cooled Demo Unit Is Fully Assembled

TAI YIAEH independently developed a 500W air-cooled PTPC demo unit, built on a full industrial aluminum extrusion frame. The front panel integrates three real-time temperature displays; the side panel features a visible window for direct observation of high-density nucleate boiling inside the cold plate—two-phase flow is not a specification on paper, but visible physical reality.

is the strongest proof.

This demo unit reproduces the complete PTPC core loop in miniature: Heat Source Simulation → Cold Plate Nucleate Boiling → Vapor Transport → Air-Cooled Condensation → Liquid Return. The air-cooled condensation design eliminates the need for an external water chiller—just plug it in and it runs, making it easy to demonstrate on-site at customer facilities or exhibitions.

Measured Case · Real-World Data

Two-Phase Flow Cooling at Constant Temperature
Real-World Measurement Data

At a heating power of 1000W, constant-temperature two-phase flow keeps the cold plate inlet and outlet temperatures nearly identical (isothermal), with the heating center staying at around 70°C—true, measured proof of excellent isothermality.

PTPC Two-Phase Flow

Live HMI screen recording—with coolant water at 36.1°C, the cold plate temperature stays stable at 38.4–38.6°C.

Two-Phase Flow Cooling at Constant Temperature

Constant-temperature two-phase flow: PTPC inlet and outlet temperatures nearly identical at about 46°C, heating center about 70°C (heating power 1000W)

Heating power 1000W. Inlet and outlet temperatures are nearly identical (isothermal), with the heating center maintained at about 70°C—stable and uniform heat dissipation. (Chart labels in Chinese.)
