SF 188™ Engineered Fluid
SF 188™ Engineered Fluid for Immersion Cooling in Data Centers
With the passage of time and technological progress, the need for more effective and reliable heat transfer solutions has increased. The power density of computer chips has become greater and greater. The workload of data centers has become more and more complex, and the heat load has been increasing. The high energy consumption not only brings high economic expenditures to all units but also causes a great waste of social resources. As a brand-new “black technology,” liquid cooling technology is gradually replacing air cooling and becoming a new type of data center cooling solution.
What is SF 188 Fluid?
SF 188 Engineered Fluid is an environmentally sustainable, affordable heat transfer fluid for two-phase immersion cooling. SF 188 is Globally Sourced and certified by the Standard Fluids Team. For more information, please contact the people you can trust at Standard Fluids Corporation.
Immersion cooling involves the cooling of IT hardware in data centers by submerging the equipment directly into a non-conductive liquid, such as SF 188 fluid. The heat produced by the electronic components is efficiently transferred directly to the fluid, eliminating the requirement for traditional cooling components like interface materials, heat sinks, fans, shrouds, and sheet metal. This method offers a more streamlined and efficient cooling solution compared to conventional approaches.

Liquid Cooling Solutions Enabled by Standard Fluids
Standard Fluids’ innovative fluids support applications in both single-phase and two-phase immersion cooling, as well as single-phase and two-phase 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.
Standard Fluids has products specifically designed for single-phase immersion cooling (see product line brochure below).
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 data center.
Direct-to-Chip Cooling
Direct-to-chip cooling expels heat by circulating fluid through cold plates attached to electronic components. 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 data center IT hardware by submerging the equipment directly into a non-conductive liquid, such as SF 188™ Engineered Fluids. 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 numerous benefits over traditional air cooling, including increased thermal efficiency (lower PUE), enhanced performance, and improved data center reliability. This method eliminates the need for complex airflow management, resulting in reductions in capital and operating expenses. Optimized immersion-cooled data centers allow for more flexible layouts, remove barriers to location choices, and address the tradeoff between water usage, energy efficiency, and cost.
In immersion cooling, IT hardware is directly submerged in a sealed but easily accessible enclosure filled with dielectric liquid. Heat is directly transferred to the fluid. Direct-to-chip cooling, on the other hand, circulates fluid through pipes to cold plates on electronic components, keeping the fluid separate from the electronics. Both methods can be implemented using single-phase and two-phase technologies with Standard Fluids.
There are two common configurations for immersion cooling: tank-style and clamshell. Tank-style immersion cooling utilizes a sealed tank filled with dielectric fluid as the heat transfer medium. Servers are vertically installed inside the tank. Clamshell design involves sealing server electronics within the server chassis, with dielectric fluid circulated through the enclosure. Servers are typically inserted horizontally into a rack.
Considerations include simplicity of tank design, fluid containment, material compatibility, and fluid hygiene for single-phase immersion cooling. Two-phase immersion cooling offers greater heat transfer efficiency, allowing for higher power densities. Additionally, two-phase systems typically require less complex cooling infrastructure.
Both fluorochemicals and hydrocarbons can be used for single-phase immersion cooling. Fluids with a higher boiling point ensure the liquid phase is maintained. Considerations when choosing among various fluids include heat transfer performance, ease of IT hardware maintenance, material compatibility, electrical properties, environmental impact, and total fluid cost over the system's lifetime.
Fluorochemical fluids with lower boiling points are primarily used for two-phase immersion cooling. Hydrocarbons are not typically used for two-phase systems due to their combustible nature. Considerations for fluid selection in two-phase cooling include impact on IT performance, ease of maintenance, material compatibility, electrical properties, environmental impact, safety-related issues, and total fluid cost over the lifetime of the tank or data center.
