The Best Heat Transfer Fluids for Liquid Cooling

The article discusses the best heat transfer fluids for liquid cooling systems. Water is recommended as the primary fluid, but glycol should be added when the set point temperature is below 10°C (48°F) to prevent freezing. Other options include dielectric fluids like perfluorinated carbons and polyalphaolefin (PAO), which are non-conductive and suitable for use with sensitive electronics. However, these fluids have lower thermal conductivity than water. The choice of heat transfer fluid depends on the specific application and requirements. Key considerations include compatibility with the system's fluid path, corrosion protection, and meeting temperature requirements.
