Fluorinated Liquids: The “Invisible Cooling Hero” Powering High-Performance Computing and the Semiconductor Industry

As artificial intelligence, 5G, and data centers continue to expand in high heat-density fields, a high-end material known as fluorinated liquid (Perfluoropolyether, PFPE) is quietly becoming the core of advanced cooling and cleaning technologies.

Composed of carbon, fluorine, and oxygen atoms, fluorinated liquid features excellent insulation, outstanding chemical inertness, and a wide operating temperature range. This allows it to directly contact electronic components for cooling without causing short circuits or corrosion.

Currently, fluorinated liquids are mainly used in three key areas:

Precision Cooling – Applied in chips, GPUs, and other components for single-phase or two-phase immersion cooling, significantly improving heat dissipation efficiency.

Electronic Cleaning – Utilizes low surface tension for residue-free precision cleaning, widely used in optical and electronic manufacturing.

Lubrication and Sealing – Serves as vacuum pump oil and sealing medium in high-vacuum and ultra-clean equipment.

Experts note that the high performance and safety of fluorinated liquids make them irreplaceable in the high-tech industry. However, high costs and recycling complexity remain the main challenges to large-scale adoption.

In the future, with advancements in manufacturing and recycling technologies, fluorinated liquids are expected to be more widely applied in data centers, semiconductor manufacturing, and aerospace, becoming a key material supporting the infrastructure of the intelligent era.

Shenzhen Huayi Brother Technology Co., Ltd. produces a wide range of fluorinated liquids that can serve as cost-effective substitutes for many 3M fluorinated products, meeting the growing global demand for precision cooling applications.
