    • The present invention relates to a process for preparing a stable suspension of carbon nanoparticles in a hydrophilic thermal transfer fluid to enhance thermal conductive properties and other characteristics such as freezing point of an antifreeze coolant. The process involves the step of dispersing carbon nanoparticles directly into a mixture of a thermal transfer fluid and other additives in the present of surfactants with intermittent ultrasonication. The present invention also relates to the composition of a hydrophilic nanofluid, which comprises carbon nanoparticles, particularly carbon nanotubes, a hydrophilic thermal transfer fluid, and at least one surfactant. Addition of surfactants significantly increases the stability of nanoparticle dispersion.
    • 本发明涉及一种在亲水热转移流体中制备碳纳米颗粒的稳定悬浮液以提高导热性能和诸如防冻剂冷却剂的凝固点的其它特征的方法。 该方法包括将间接超声波处理将表面活性剂中的碳纳米粒子直接分散到热转印流体和其它添加剂的混合物中的步骤。 本发明还涉及亲水性纳米流体的组成,其包含碳纳米颗粒,特别是碳纳米管,亲水性热转移流体和至少一种表面活性剂。 表面活性剂的添加显着增加了纳米颗粒分散体的稳定性。
