Fluorosilicone oil liquid cooling technology revolutionizes the heat dissipation mode of data centers

1.The breakthrough in immersion liquid cooling technology enables fluorosilicone oil to achieve low-cost and efficient heat dissipation
The new type of composite fluorosilicone oil coolant has made a major breakthrough in the field of immersion liquid cooling for data centers. The fluorosilicone oil coolant developed by a certain research team has a cost 80% lower than that of traditional fluorinated liquids (from 500,000 yuan per ton to within 100,000 yuan per ton), while maintaining a heat dissipation performance of 85%. This material optimizes the phase transition ratio through molecular design, solving the problem of excessive phase transition in traditional phase transition coolants affecting heat conduction. It demonstrates excellent flame retardant performance in the 600 ° C flame gun test. A test conducted by a certain data center of Alibaba Cloud shows that after adopting the fluorosilicone oil liquid cooling solution, the PUE value dropped from 1.4 to 1.1, and the annual power consumption decreased by 30%.


In the field of energy storage, fluorosilicone oil liquid cooling technology also performs well. Catl's latest energy storage system uses fluorosilicone oil as the thermal management medium. The cycle life of the battery cells has been increased from 3,000 times to 4,000 times, and the energy density has exceeded 300Wh/kg. The measured data of a certain energy storage power station shows that the battery pack cooled by fluorosilicone oil liquid has a capacity retention rate of 78% in an environment of -40 ℃, which is 36% higher than that of the traditional air cooling solution.

2. It leads in safety performance. The fluorosilicone oil liquid cooling has passed the strict national standard tests
The safety performance of the fluorosilicone oil liquid cooling system has been certified by authoritative authorities. The fluorosilicone oil coolant developed by a certain enterprise has passed the test of GB/T 36531-2018 "Safety Requirements for Battery Systems for Power Storage". It can still remain stable in the case of thermal runaway of the battery cells, with no open flame and no smoke release. In the extreme test, the coolant remained undecomposed for one hour at a high temperature of 1000℃, and the volatile organic compounds (VOCs) emissions were less than 0.1ppm, meeting the requirements of the EU REACH regulation.

In the aerospace field, fluorosilicone oil liquid cooling technology has been applied to satellite thermal control systems. A certain satellite uses fluorosilicone oil as the phase change coolant. During the extreme temperature cycle from -180 ℃ to + 150℃, the response time of the thermal control system is shortened to 0.5 seconds, and the temperature control accuracy reaches ±0.1℃, ensuring the stable operation of the on-board equipment.

3. Industrial-grade application expansion: Fluorosilicone oil liquid cooling is suitable for multiple scenario requirements
The application of fluorosilicone oil liquid cooling technology in the industrial field has expanded rapidly. A certain automobile manufacturing enterprise uses fluorosilicone oil for cooling the battery packs of new energy vehicles, reducing the volume of the battery packs by 20% and increasing the charging speed by 25%. A certain chemical enterprise adopted a fluorosilicone oil liquid cooling system to cool the reaction vessels, raising the temperature control accuracy from ±5℃ to ±1℃ and increasing the product purity from 95% to 99%.


In the field of rail transit, fluorosilicone oil liquid cooling technology has solved the heat dissipation problem of high-speed rail traction converters. The actual measurement of a certain high-speed railway line shows that when the converter using fluorosilicone oil liquid cooling operates at 350km/h, the temperature of the core components is 20℃ lower than that of the traditional air-cooling scheme, and the maintenance cycle is extended from 3 months to 1 year.

4. Driven by policies and market growth, the prospects for fluorosilicone oil liquid cooling are broad
The national "East Data West Computing" project and the "dual carbon" goals have driven the rapid growth of the fluorosilicone oil liquid cooling market. It is estimated that by 2030, the domestic liquid cooling market size of data centers will exceed 50 billion yuan, among which the proportion of fluorosilicone oil liquid cooling will reach 40%. At the policy level, the "Three-Year Action Plan for the Development of New-Type Data Centers" released by the Ministry of Industry and Information Technology clearly lists immersion liquid cooling as a key technology to be promoted, and provides a 15% financial subsidy for projects that adopt fluorosilicone oil liquid cooling.

In international competition, domestic fluorosilicone oil liquid cooling technology has rapidly captured the market by virtue of its cost-performance advantage. The fluorosilicone oil coolant of a certain enterprise has passed the UL 94 V-0 fire protection certification. Its price is only 70% of that of similar products in Germany. The market share in Europe is expected to exceed 12% in 2025. In the future, with the introduction of international standards such as the "Technical Standard for Liquid Cooling in Data Centers", the technological output of Chinese enterprises will further accelerate.
