Two-phase dielectric immersion coolant

A chokepoint created by regulation rather than geology: PFAS restriction is withdrawing the incumbent fluorinated chemistry precisely as immersion cooling starts to scale.

Grade that ships · Engineered fluid, boiling point matched to the target die temperature.

Part of the process · Energy, which takes years to loosen once somebody decides to.

The main supplier left fluorochemicals. Single-phase and water alternatives exist; the two-phase niche needs a new source.

  Better conduction at the die reduces how much the cooling fluid has to do.

  In liquid immersion cooling with the low-GWP refrigerant R1233zd(E), the onset of nucleate boiling (ONB) governs both the wall temperature and the thermal margin. A real-time digital twin needs a fast differentiable surrogate of the boiling closure rather than repeated evaluation…

A loop is one design, build and measure turn. Severity is a dated judgement on a 0–12 scale, not a measurement, and the judgements are not added together — the figure shown is the worst single one.
