Zusammenfassung: | thermal engineering; miscellaneous heaters converting radiant energy of sun and the like into heat. SUBSTANCE: known coolant composed of water and sodium chloride is modified by introducing following ingredients: cuprous chloride, methyl thymol blue, and methyl blue, their proportion being as follows, mass percent: water, 60.5-76.5; cuprous chloride, 0.05- 39.5; sodium chloride, 0.05-23.5; methyl thymol blue, 0.002-0.02; methyl blue, 0.003-0.03. Coolant of proposed composition has lower freezing temperature which prevents damage to coolant-using device at subzero temperatures and provides for better absorption in visible region of spectrum. EFFECT: enhanced efficiency of radiant energy conversion to heat. 2 cl, 3 dwg |
