As higher clock frequencies and smaller transistor dimensions continue to increase the power density of high-performance computing technologies, such as CPUs, GPUs, FPGAs, Laser Diodes, and Optical electronics, advances in thermal management technologies for these applications are necessary to prevent performance limitations. Many military, government, industrial, and consumer applications are becoming dependent on cloud resources and high-performance computing clusters, all of which are housed in data centers and facilities, whose designers are struggling to meet the cooling needs of emerging systems. New synthetic dielectric coolants may offer several advantages over traditional petroleum based dielectric oils for some applications, which is the basis for a new whitepaper, “Mineral Oil, White Oil and Synthetic Dielectric Coolants,” by Dr. David W. Sundin, Chief Scientist of Engineered Fluids, LLC.
In this white paper, the manufacture of mineral oils, white oils, and synthetic dielectric coolants is discussed. The main difference of petroleum-based dielectric oils and synthetic dielectric coolants is outlined, which centers on the differences between the process of petroleum refinement and the developed of highly processed synthetic chemicals. A comparison of the purity and consistency of petroleum-based dielectric oils and synthetic dielectric coolants is shared, and an example of the differences is given with a gas chromatograph plot of of white mineral oil and Engineered Fluids proprietary dielectric coolants.
The white paper further describes the health, safety, and biodegradability differences between petroleum-based dielectric oils and synthetic dielectric coolants, and the paper mentions several areas where petroleum products pose risks where synthetic dielectric coolants are likely substantially safer. Other differences between the two types of dielectric coolants, such as the intended purpose of the materials, known characteristics, viscosity and temperature stability, and material compatibility, are also discussed in the white paper. Lastly, the paper infers a difference in heat transfer effectiveness between the two types of collants with a description and blog of a viscosity comparison of Engineered Fluids proprietary synthetic dielectric coolant and 80 SUS white oils.
