Abstract: Coolants with low electrical conductivity and the corresponding coolant concentrates are made. A method is developed for circulating the coolants in cooling systems of vehicles with electric engines, fuel cells or hybrid engines with a combination of combustion engines with electric engines or a combination of combustion engines with fuel cells.

Abstract: Coolants with low electrical conductivity can be used in direct or indirect cooling of electronic devices. The coolant has at least one glycol, water, at least one azole derivative, at least one ester of orthosilicic acid or alkoxy alkylsilane, optionally at least one tertiary amine bearing at least one 2-hydroxyethyl- or 2-hydroxypropyl-group, optionally at least one monocarboxylic acid, optionally at least one silicophosphonate, and optionally at least one further coolant additive.
