Immersionjahutust

Immersionjahutust, also known as immersion cooling, is a method of removing heat from electronic equipment by submerging the devices in a dielectric coolant. The liquid surrounds heat-generating components, allowing direct heat transfer from CPUs, GPUs, memory, and power electronics to the surrounding fluid. Two main approaches are used: single-phase immersion cooling, where the dielectric liquid circulates and releases heat through a heat exchanger without boiling; and two-phase immersion cooling, where the liquid boils inside the immersion tank and the resulting vapor carries away latent heat, with condensation returning liquid to the bath.

Fluids used are dielectric and non-conductive, including mineral oils, silicone oils, and fluorinated liquids. The choice depends on thermal performance, safety, environmental impact, and material compatibility. Systems may be designed as open baths, sealed tanks, or racks immersed in the liquid, with considerations for electrical isolation, corrosion resistance, and cleanliness.

Benefits of immersionjahutust include the potential for higher cooling efficiency, reduced reliance on traditional air-based cooling, quieter operation due to fewer fans, and the possibility of higher hardware density in data centers or high-performance computing environments. It can also simplify cooling infrastructure by reducing or reconfiguring heat exchangers and ductwork.

Challenges include higher initial costs, the need for specialized dielectric fluids and containment, maintenance and leak risk, and the requirements for system redesign when retrofitting existing deployments. Some fluids pose safety, environmental, or disposal concerns, and material compatibility must be carefully managed.

Applications span data centers, high-performance computing, and crypto-mining facilities, with ongoing research into broader industrial and military electronics use.
