Immersion cooling. Immersion cooling is an IT cooling practice by which complete servers are immersed in a dielectric, electrically non-conductive fluid that has significantly higher thermal conductivity than air. Heat is removed from a system by putting the coolant in direct contact with hot components, and circulating the heated liquid ...
In computing and electronics, liquid cooling involves the technology that uses a special water block to conduct heat away from the processor as well as the chipset. [1] This method can also be used in combination with other traditional cooling methods such as those that use air. The application to microelectronics is either indirect or direct ...
Some fluids used in immersion cooling, especially hydrocarbon based materials such as mineral oils, cooking oils, and organic esters, may degrade some common materials used in computers such as rubbers, polyvinyl chloride (PVC), and thermal greases. Therefore it is critical to review the material compatibility of such fluids prior to use.
Novec 649 is a low-temperature heat-transfer fluid. It has been used as a full-immersion fluid in a proof of concept data center cooling system by Intel and SGI. [7] As it boils off easily due to its 49 °C (120.2 °F) boiling point, it is used in two-phase immersion cooling system with a condensing loop running cold water.
Fluorinert is the trademarked brand name for the line of electronics coolant liquids sold commercially by 3M. As perfluorinated compounds (PFCs), all Fluorinert variants have an extremely high global warming potential (GWP), [1] so should be used with caution (see below). It is an electrically insulating, stable fluorocarbon -based fluid, which ...
The experiment compared the effectiveness of mitigating temperature generated by the WAAM between natural cooling, passive cooling, and near immersion active cooling. Natural cooling used air, passive cooling used a cooling liquid that stays on a fixed level, and NIAC used a cooling liquid that rises based on the actions of the WAAM. [11]
3M produces hydrofluoroether compounds under the names Novec 7000, 7100, 7200, 7300, 7500, and 7700 as liquid coolants for many applications including full immersion cooling of computer electronics. [ 3 ]
Immersion lithography is a technique used in semiconductor manufacturing to enhance the resolution and accuracy of the lithographic process. It involves using a liquid medium, typically water, between the lens and the wafer during exposure. By using a liquid with a higher refractive index than air, immersion lithography allows for smaller ...
