Abstract:

A review of the status of extreme temperature range ETR coolants for electronic equipment is presented. The fluids considered for use over a -80 F to 400 F temperature range are described in this report and fall into the following class of compounds amines, chlorofluoro-carbon oils, fluorochemicals, silicones, silicate esters, and siloxanes. Results show that the silicone fluids comply most closely to the physical properties required for ETR electronic coolants. It was observed that they are the only group of materials that possess high boiling points and thermal stabilities above the 400 F bulk operational temperature, and still display reasonably low viscosity values within the extreme temperature range. The electrical properties of these materials are also very desirable. The data on the new experimental research fluids, list properties important to future coolants for electronic components. These data include the viscosity-temperature relation, vapor pressuretemperature properties electrical characteristics, thermal properties and flammability characteristics. Author
