Dieletric fluids, what are they and what are they meant to. We have already talked recently about dielectric fluids related to the cooling of PCB immersed in fluids, also referred to as liquid cooling. These are in fact usually employed in applications of free cooling for data centers where PCBs are directly immersed in a dielectric fluid and therefore a fluid that doesn’t conduct electricity.

These same dielectric fluids are as well employed for the testing of thermoregulation and cooling systems of data centers or for other electronics components, for example in the automotive industry, or also in the production of batteries for electric vehicles, in order to evaluate the performances of these components when the temperature varies.

On a construction perspective, the employ of these fluids involve very few changes on thermoregulating units because eventually dielectric fluids are very similar to oils both for their physics and thermodynamic characteristics. Therefore, the components used in the temperature control units that use these particular fluids are also quite the same.
