Embodiment 1

[0047]Nano long-term cooling liquid is Cu-PG nanofluid. That is: add 2% Cu metal nanoparticles to 85.59% PG, 10% DW base liquid, add 2% SDBS dispersant, add 0.1% sodium molybdate, 0.1% sodium benzoate, 0.1% BTA and TTA mixture to In the base liquid, after stirring and dissolving, take it out after ultrasonic vibration for 3 hours, then add 0.01% coloring agent, add 0.1% ammonia water to adjust the pH value to 9.1, and fully stir evenly to form a uniform and stable Cu-PG nanometer Coolant. The thermal conductivity of the fluid is 21% higher than that of the base fluid measured by the transient hot wire method. The percentages of the above raw materials are percentages by weight.

Embodiment 2

[0049] Nano long-term cooling liquid is CuO-GC nanofluid. That is: add 5% CuO metal nanoparticles to 77% GC, 15.97% DW base fluid, add 0.8% SDBS dispersant, add 0.1% sodium molybdate, 0.1% sodium benzoate, 0.1% BTA and TTA mixture to In the base liquid, after stirring and dissolving, put it into ultrasonic vibration for 3 hours and take it out, then add 0.03% coloring agent, add 1% ammonia water to adjust the pH value to 8.5, fully stir evenly, and it becomes CuO-GC nano cooling liquid . The thermal conductivity of the fluid is 30% higher than that of the base fluid. The percentages of the above raw materials are percentages by weight.

Embodiment 3

[0051] Nano long-term coolant is Al2O3-PG, GC nanofluid. That is: add 0.3% Al to 10% PG, 59.49% GC, 29% DW base fluid 2 o 3 For metal nanoparticles, add 0.4% PEG400 dispersant, then stir and dissolve 0.1% sodium molybdate, 0.1% sodium benzoate, 0.1% BTA and TTA mixture in PG, add it to the base liquid, and put it into ultrasonic vibration for 3 Take it out after 1 hour, add 0.01% coloring agent, add 0.5% hydrochloric acid to adjust the pH value to 5.1, stir well and evenly, and serve as PG-GC mixed nano-coolant. The thermal conductivity of the fluid is 19% higher than that of the base fluid. The percentages of the above raw materials are percentages by weight.

Abstract

The invention discloses a nano long-acting liquid coolant. The nano long-acting liquid coolant comprises the following components of a base liquid which is composed of diatomic alcohol and a diluent, metal nanoparticles with a particle size of 3-100nm or carbon nano tube particles with a tube diameter of 8-100nm and length of 100-600nm, a dispersing agent, a corrosion inhibition additive, a pH regulator and a fluorescence colorant. The nano long-acting liquid disclosed by the invention is high in heat conductivity coefficient, good in heat transfer performance, good in liquidity and low in cost.

Description

technical field [0001] The invention relates to coolant, especially used in automobiles, trucks, motorcycles, airplanes, trains, tractors, generators, compressor engines, marine engines, power systems, industrial engines, electrical generators, fuel cell engines and hybrid power Coolant in the engine. Background technique [0002] Most of the coolants currently used in engines on the market are basically ethylene glycol-water (EG-H 2 O) type coolant, in the human body, the products of EG are hydroxyl, acetic acid, oxalic acid, which can easily cause the body's acid-base balance imbalance and damage the kidneys; during use, EG will evaporate into the air with water, and after replacement Most of the EG in the cooling liquid is spilled on the ground, causing environmental and air pollution, and causing harm to people and animals. Since EG is a highly toxic and difficult-to-biodegrade compound, it is classified as a Class 4 toxic compound in the Swiss Federal Poison Law, and ...
