The physical-chemical properties of the SmartCoolant, allow higher heat transfer performance than air. The SmartCoolant liquid used by Submer in our Immersion Cooling solutions is a dielectric, synthetic, proprietary fluid, 100% non-hazardous for people or the environment and readily biodegradable according to OECD 301. ![]() Non-purpose oils, including cooking, motor and silicone oils, have been successfully used for cooling personal computers. Immersion Cooling systems used to have a higher fluid cost than water cooling, but this is already changing.Ī wide variety of liquids exist for this purpose, the most suitable being transformer oils and other electrical cooling oils. With Immersion Cooling the working fluid must be non-conductive and that generally limits us to four families of fluids: A watertight waterblock is used to indirectly transfer the heat from the heat source to the working fluid. In “watercooling” the working fluid is potentially harmful to electronics and thus flows through a sealed loop isolated from the heat source. With Immersion Cooling the heat is transferred directly from the heat source to the working fluid. Is Immersion Cooling the Same Thing as “Water Cooling”? For these reasons, it is preferred that the liquid be dielectric. If the liquid is somewhat electrically conductive, it may be necessary to insulate certain parts of components susceptible to electromagnetic interference, such as the CPU. The liquid used must have sufficiently low electrical conductivity not to interfere with the normal operation of the computer. Some extreme density supercomputers such as the Cray-2 and Cray T90 use large liquid-to-chilled liquid heat exchangers for heat removal. IT Hardware or servers cooled in this manner don’t require fans and the heat exchange between the warm coolant and cool water circuit usually occurs through a heat exchanger (i.e. Still rarely used for the cooling of IT Hardware, this method is slowly becoming popular with innovative datacenters the world over. Liquid submersion is a routine method of cooling large power distribution components such as transformers. Also known as liquid submersion cooling, it is the practice of submerging computer components (or full servers) in a thermally, but not electrically, conductive liquid (dielectric coolant).
