Abstract

The invention relates to heat-conduction fluid, which comprises the following components: 1.2-3.2 wt% of calcium chloride, 2.5-4.5wt% of absolute ethyl alcohol, 0.5-1.5wt% of sodium perborate, 1.2-2.7 wt% of sodium nitrate, 0.8-1.5wt% of potassium hydroxide, 1.2-2.7 of potassium phosphate, 0.2-0.8 wt% of benzotriazole and the rest of distilled water. The superconductive fluid disclosed by the invention has the characteristics of antifreezing property, antirust property, antifoam property, non-toxicity, environment-friendliness, stable property and good heat transmission effect. After a heat transmitter uses the heat-conduction fluid disclosed by the invention, the service life of the heat transmitter can be remarkably prolonged, and the heat transmission property of the heat transmitter can be remarkably improved.

Description

technical field [0001] The invention relates to a heat transfer fluid. Background technique [0002] The most commonly used heat transfer medium is water, and the heat transfer temperature range is 5-90°C. Outside this temperature range, water cannot be used as a heat transfer agent because it tends to freeze or boil. The advantage of using water as a heat transfer agent is good heat transfer effect and low cost, but its disadvantage is that it corrodes equipment and is easy to scale; other commonly used heat transfer media include inorganic salts, such as sodium chloride aqueous solution, calcium chloride Aqueous solution, this type of heat transfer medium is severely corrosive to various metals and stainless steel, and has been gradually replaced by organic alcohol heat transfer media, such as anhydrous ethanol aqueous solution and propylene glycol aqueous solution; Lightweight, but still severely corrosive to carbon steel and other metals. A heat exchange system, if the...
