Abstract

FIELD: heat transfer by heat- transfer agents; applicable in cooling system of radio technical apparatuses. SUBSTANCE: used for the purpose is heat-transfer agent based on aqueous solution of ethylene glycol containing N, N-dimethyl formamide, corrosion inhibitors and aromatic carboxylic acids and/or their salts with the following amounts of the components, mas.%: ethylene glycol 25-40; N,N-dimethyl formamide 25-40; aromatic carboxylic acids and/or their salts 0.02-0.05; corrosion inhibitors 0.02-0.10; the balance, water. Aromatic carboxylic acids and/or their salts are used in form of mixture of n-hexaoxybenzoic acid and/or phenylandecanoic acid with isomerphine and/or N-phenylanthranilic acid in ratio of 1:1. Corrosion inhibitors are used in form of mixture of benzimidazole and/or benzotriazole with sodium salt of 1-oxynaphthoic acid or zinc salt of 1-oxyethyliden- diphosphonic acid. EFFECT: reduced viscosity at subzero temperatures, increased anticorrosion property with respect to ferrous and nonferrous metals and imparted property of heat-transfer agent of absorbing ultraviolet radiation. 2 cl, 2 tbl
