Immersion chillers are also used in cooling computers. This is known as liquid submersion cooling. It is most commonly used to cool transformers that power large computer networks and data centers. This is done by submerging computer components in a thermally conductive liquid instead of using fans. The liquid chosen for this purpose must have low electro conductivity. This prevents electromagnetic interference with the component functions. Some pieces may be insulated to prevent interference. Most of the time the liquid is a transformer oil specifically manufactured for this cooling purpose. An example of which is 3M Fluorinert.
