Why Two-Phase, Direct-to-Chip Cooling is Different

Two-phase cooling uses dielectric fluid inside a compact cold plate mounted directly on CPUs and GPUs. As heat is generated, the fluid boils and turns into vapor—holding the chip at a constant, predictable temperature, regardless of power.

This approach:

  1. Uses no water in the cold plate

  2. Eliminates hot spots through advanced wick-and-fin structures

  3. Scales naturally to higher-power AI chips

  4. Enables heat reuse and ultra-low PUE
