Dow
Chemical major supplying DOWSIL silicone single-phase immersion fluids, led by the R&D 100-winning DOWSIL ICL-1000, and DOWFROST LC 25, a pre-diluted 25% inhibited propylene glycol coolant dyed yellow for leak detection in direct-to-chip loops.
Rating conditions
DOWSIL immersion fluids: dielectric constant 2.1–2.2, viscosity 10–30 cSt at 40°C. DOWFROST LC 25: 25% propylene glycol, pre-diluted.
Datasheet
Source on every value- Technologies Liquid cooling product types the vendor sells today. 'Liquid-to-air CDU' is a sidecar unit or heat dissipation unit that needs no facility water. 'Two-phase cold plate' boils a refrigerant or dielectric on the chip.
