Ionic liquids are a very new class of fluids with excellent tunable properties and recently considered also for heat exchange applications. This review paper come into support of the 1-Butyl-3-methylimidazolium tetrafluoroborate ionic liquid state of the art, shedding some light on its properties, general applications and use as possible heat transfer fluid. Plus, adding solid high conductive nanoparticles, the ionic liquid thermal conductivity is greatly improved, while the increase in viscosity is reasonable. These features make it a perfect candidate for heating and cooling operations, especially at higher temperatures.

The article discusses 1-Butyl-3-methylimidazolium tetrafluoroborate ionic liquid properties in terms of density, thermal conductivity, specific heat and viscosity proposing several experimental correlations. In addition, studies on nanocolloids based on 1-Butyl-3-methylimidazolium tetrafluoroborate are reviewed and debated in terms of thermophysical properties variation with nanoparticle mass concentration and temperature. Concluding, even if there are several studies in the open literature, more experimental work is mandatory in order to get a full picture of ionanocolloids real life applications.
