This review discusses, in terms of practical aspects and future application, about heat transfer fluids properties with special focus on the possible use of ionic liquids in heat transfer applications. Even if some data were identified in the open literature, most of the ionic liquids studies on thermophysical properties are yet at the beginning and fully described chemicals are scarce. The most relevant thermophysical properties of ionic liquids (density, specific heat, thermal conductivity, and viscosity) are paralleled with the properties of several commercial heat transfer fluids. A consistent attention is paid to the analysis of heat transfer coefficient and friction factor, as well as Prandtl number. Concluding, ionic liquids can be seen as an alternative to regular heat transfer oils, however, a consistent experimental approach using real-life geometries and conditions is mandatory to be developed to fully understand all the processes.

离子液体概述作为新型传热流体的候选者

这篇综述从实际应用和未来应用的角度讨论了传热流体的特性，特别关注离子液体在传热应用中的可能用途。即使在公开文献中确定了一些数据，大多数关于热物理性质的离子液体研究仍处于起步阶段，并且缺乏充分描述的化学物质。离子液体最相关的热物理特性（密度、比热、热导率和粘度）与几种商业传热流体的特性是平行的。对传热系数和摩擦系数以及普朗特数的分析一直受到关注。总之，离子液体可以被视为常规导热油的替代品，然而，
