Will electronic fluorinated fluids undergo irreversible chemical degradation or performance degradation in cooling systems?

Under normal cooling system operating conditions, fluorinated fluids will not undergo irreversible chemical degradation or performance degradation. Its single-component design, chemical inertness, and long-term physical stability (such as viscosity and dielectric constant) ensure long-lasting and reliable performance. However, it should be noted that:

If a leak occurs, fluorinated fluids are difficult to degrade in the environment and may cause pollution. Fluorinated fluids with different formulations may have different performances (such as the gap between substitutes and FC-3283 is narrowing), but the degradation problem is not mentioned. Therefore, in a closed cooling system, the risk of performance degradation of fluorinated fluids is extremely low, and it is a reliable choice for high-precision heat dissipation scenarios such as semiconductors and data centers.

1. Fluorinated fluids usually have excellent chemical stability

The core advantage of fluorinated fluids lies in their chemical inertness and stability. For example: FC-3283 fluorinated fluid is a single-component perfluoroamine compound that will not degrade due to fractionation and is suitable for semiconductor manufacturing and data center immersion cooling. The single-component design of 3M fluorinated fluids avoids performance degradation caused by changes in components over time and ensures long-term stability. The chemical stability of fluorinated fluids makes it difficult to react with other materials and can maintain stable performance for a long time. Fluorinated liquid is a "highly stable" and "chemically inert" liquid that is compatible with metals and engineering plastics.

2. Physical parameters remain stable during long-term use

China Fluorine Technology has verified the long-term stability of fluorinated liquid in a single-phase immersion liquid cooling system through experiments: China Fluorine Technology's tests show that the physical parameters such as viscosity, dielectric constant and breakdown voltage of fluorinated liquid have no significant changes after long-term use, meeting the long-term operation requirements of the server. In immersion cooling, changes in system parameters (such as CPU load fluctuations) of perfluorocarbon structure fluorinated liquid will not have a serious impact on the cooling effect, further proving its stable production.

3. The difference between environmental leakage risk and degradation within the system

Fluorinated liquid has the problem of "chemical properties being stable and difficult to degrade" in the environment, but this is for pollution after environmental leakage (such as water source pollution), not performance degradation within the cooling system. Degradation of fluorinated membranes in fuel cells (involving free radical reactions), but this scenario is different from the operating conditions of the cooling system (no electrochemical reaction) and is not directly applicable to the coolant scenario.

4. Performance in practical applications

Fluorinated fluids are efficient and stable in immersion cooling: phase-change fluorinated fluids can quickly boil away heat, and test data confirms their reliability. FC-40 fluorinated fluids extend equipment life by reducing operating temperatures and preventing electrical failures. In plasma cooling, fluorinated fluids have a much smaller impact on system impedance than other coolants, indicating their operational stability.
