Liquid Cooling Solutions Enabled by Standard Fluids
Standard Fluids’ innovative products support applications in both single-phase and two-phase immersion cooling, as well as direct-to-chip applications.
Single-Phase Immersion Cooling: In single-phase immersion cooling, the fluid remains in its liquid phase. Electronic components are directly immersed in a dielectric liquid within a sealed yet easily accessible enclosure. The heat from electronic components transfers to the fluid, and pumps are often employed to circulate the heated fluid to a heat exchanger. There, it undergoes cooling before being recirculated back into the enclosure.
Two-Phase Immersion Cooling: Two-phase immersion cooling involves the boiling and condensation of the fluid, significantly enhancing heat transfer efficiency. Electronic components are immersed in a dielectric liquid within a sealed yet easily accessible enclosure. Heat from the components causes the fluid to boil, generating vapor that rises from the liquid. The vapor then condenses on a heat exchanger (condenser) within the tank, transferring heat to facility water circulating outside the system.
Direct-to-Chip Cooling: Direct-to-chip cooling expels heat by circulating fluid through cold plates attached to electronic components. The fluid never makes direct contact with the electronics.
While non-dielectric fluids (e.g., water, glycol) are common in direct-to-chip cooling, dielectric fluids can be employed in these applications to mitigate leak-related risks, thereby enhancing hardware and IT equipment reliability. Direct-to-chip cooling can be implemented using both single-phase and two-phase technologies.

Frequently Asked Questions about Immersion Cooling
Immersion cooling is a technique for cooling industrial systems by submerging equipment directly into a non-conductive liquid such as SF 649 fluid. The heat generated by electronic components is efficiently transferred directly to the fluid, eliminating the need for traditional cooling components like interface materials, heat sinks, fans, shrouds, and sheet metal.
Immersion cooling with Standard Fluids’ products offers increased thermal efficiency, enhanced performance, and improved system reliability. This method eliminates the need for complex airflow management, reducing capital and operating expenses.
In immersion cooling, IT hardware is directly submerged in a sealed enclosure filled with dielectric liquid. Direct-to-chip cooling circulates fluid through cold plates on electronic components, keeping the fluid separate from the electronics.
Considerations include tank design, fluid containment, material compatibility, and fluid hygiene for single-phase immersion cooling. Two-phase immersion cooling offers greater heat transfer efficiency and typically requires less complex cooling infrastructure.
