KOOL PHASE technology

A new approach to
the thermal cycle.

KOOL PHASE is developing a direct-to-chip liquid-cooling architecture designed around controlled phase change inside the Coolant Distribution Unit (CDU).

The architecture

Capture heat at the chip. Control the phase change in the CDU.

At the hardware

Direct-to-chip heat capture

Heat is captured at the computing hardware through a direct-to-chip liquid loop and transported away from the processors.

Inside the CDU

Controlled phase change

Controlled phase change is designed to occur inside the KOOL PHASE Coolant Distribution Unit, not around the server hardware.

KOOL PHASE is not conventional immersion cooling. Computing hardware is not submerged in coolant.

Controlled thermal cycle

Turning heat into a controlled cycle.

  1. 01Heat Capture

    Thermal energy is captured at the compute hardware through direct-to-chip cooling.

  2. 02Liquid Transport

    The liquid loop carries captured heat away from the processors.

  3. 03Controlled Phase Change

    Inside the Coolant Distribution Unit (CDU), the working fluid is designed to use phase change.

  4. 04Heat Rejection

    Thermal energy is transferred away from the primary compute loop.

  5. 05Condensation

    The working fluid returns toward a liquid state as heat is rejected.

  6. 06Liquid Return

    The cooled liquid continues through the thermal-management cycle.

Direct-to-chip heat capture at the hardware. Controlled phase change inside the Coolant Distribution Unit (CDU).

Why phase change

Using the thermal cycle more intelligently.

Phase change can move significant thermal energy by using the latent heat associated with a fluid changing state. KOOL PHASE is being developed around using that behaviour inside the CDU.

What the architecture is being designed to support

  1. 01

    Smaller infrastructure footprint

    Targeting a more compact approach to thermal infrastructure.

  2. 02

    Reduced cooling overhead potential

    Being developed to use cooling infrastructure more intelligently.

  3. 03

    Lower water dependency potential

    Designed with the potential to reduce reliance on water-intensive cooling.

  4. 04

    Modular architecture

    An architecture intended to adapt to varied environments and requirements.

Development through validation

Engineer. Validate. Improve. Scale.

KOOL PHASE is being developed through an engineering-led process intended to test, measure, and refine the thermal architecture.

Defined pilot environments can help build the evidence needed to guide future development.
