Abstract
An immersion cooling system includes a fluid-retaining container having space for accommodating an electronic device. A heat transfer fluid is in contact with the electronic device. A heat exchanger contacts and condenses vapor from vaporization of the heat transfer fluid. The heat transfer fluid has a thermal conductivity higher than 0.08 W mK, a dielectric constant (D) 20-40 GHz less than 3.0, and a heat of vaporization higher than 150 kJ kg, with fire retarding features, compatibility with plastics, metals, rubbers and includes a partially fluorinated compound. The improved immersion cooling system includes fluids with increased thermal conductivity and heat of vaporization while reducing fluid density and maintaining the advantages of the fluid being non-flammable, having high electrical stability and a low dielectric constant.
