A recently filed patent (Publication Number: US20230313015A1) describes a direct single phase immersion cooling system and method for cooling electronic hardware using a renewable paraffinic composition. The system includes a bath containing a renewable paraffinic composition that consists of at least 80% paraffins in the C16-C19 range. The electronic hardware is immersed in this composition for cooling purposes.

The method for single phase immersion cooling involves providing a bath with the renewable paraffinic composition and immersing the electronic hardware in it. The electronic hardware can be a server or other computer hardware. The method also includes circulating the renewable paraffinic composition through a heat exchanging unit to facilitate cooling. The temperature of operation for this method ranges from 15°C to 90°C.

The renewable paraffinic composition used in this cooling system comprises more than 90% paraffins based on the total weight of the composition. It also contains 90% or more paraffins in the C16-C19 range. Additionally, the composition consists of more than 60% isoparaffins and 5% or less naphthenes. It has less than 2% C15 and lighter paraffins, as well as less than 5% C20 and heavier paraffins.

Furthermore, the renewable paraffinic composition includes more than 37% C17 paraffins based on its total weight. It also contains more than 90% paraffins in the C17-C18 range, with a ratio of C18 i-paraffins to C18 n-paraffins exceeding 40. The composition has a flash point of at least 125°C, a kinematic viscosity below 15 mm2/s at 40°C, and a density ranging from 700 to 850 kg/m3 at 20°C. It also exhibits an electrical conductivity of less than 1 pS/m at 22°C.

The renewable paraffinic composition used in this cooling system has specific thermal properties. It has a volumetric specific heat ranging from 1.60 MJ/(m3K) to 1.90 MJ/(m3K), a thermal conductivity ranging from 0.11 W/(m·K) to 0.15 W/(m·K), and a thermal diffusivity ranging from 0.06 mm2/s to 0.09 mm2/s, all measured at 20°C. Additionally, the composition has a biogenic carbon content of at least 50% based on the total weight of carbon in the composition.

Overall, this patent describes a direct single phase immersion cooling system and method that utilizes a renewable paraffinic composition for cooling electronic hardware. The composition has specific characteristics and properties that make it suitable for efficient and effective cooling.
