The results of studies of the cooling capacity, rheological and surface-active properties of aqueous solutions of oligomers: mono- and dipolyethylene glycol esters of oleic acid are presented. The availability of these oligomeric surfactants and the complex of their physicochemical properties make it possible to obtain, by varying the concentration of components, the compositions of hardening media (QM) with the required indicators. The process of cooling in oligomeric solutions depends on the concentration and stereochemistry of surfactant molecules. An increase in the content of oligomers is accompanied by a decrease in the rate and a shift in the maxima of the cooling rate curves towards low temperatures. As a result of comprehensive studies, a substantiated version of the heat transfer mechanism during cooling of a metal sample in aqueous micellar solutions of oligomeric surfactants was proposed. The stereochemistry of surfactant molecules, the shape of micelles, their strength, and ability to rearrange determine the complex mechanism of adsorption interaction with the metal surface, thus affecting the stages of shock boiling, vapor film, and nucleate boiling, and, ultimately, the intensity of heat transfer and the magnitude of the heat flux.
