Abstract

The invention discloses a preparation method of nanofluid cooling liquid and the nanofluid cooling liquid prepared by the same. The preparation method comprises the following steps of: uniformly mixing dibasic alcohol, de-ionized water and alkali to obtain basic liquid; adding ethyl silicate into the basic liquid and hydrolyzing the mixture to obtain nanofluid containing silicon dioxide nanoparticles; and adding a dispersion stabilizer, a corrosion inhibitor and a coloring agent into the nanofluid to obtain the nanofluid cooling liquid. The preparation method provided by the invention has the characteristics of simple equipment and process, mild conditions, high raw material utilization rate, low cost, easiness for large-scale production and the like. The prepared nanofluid cooling liquid has high stability and high heat exchange capacity.

Description

Technical field: [0001] The invention relates to a preparation method of a nanofluid cooling liquid and a prepared nanofluid cooling liquid, belonging to the field of engine cooling liquids. Background technique: [0002] With the continuous improvement of the power density of modern engines, traditional coolants (ethylene glycol type, propylene glycol type) have been unable to meet the high-load heat dissipation requirements of the cooling system due to their low thermal conductivity and poor heat exchange capacity. It is necessary to develop new and efficient Coolant for heat exchange. The emergence of nanofluid technology provides new ideas for the development of engine cooling systems. Nanofluid is a new type of heat exchange working medium formed by stably suspending metal or non-metal nanoparticles into traditional fluids (water, glycol, etc.). Existing studies have shown that, compared with traditional fluids, nanofluids have higher thermal conductivity and excellent hea...
