Disclosed is a corrosion inhibitor for use in heat transfer fluids having a conductivity of less than 200 ~S/cm, the corrosion inhibitor having an azole compound, and at least one of a siloxane based surfactant, colloidal silica, or a mixture thereof. Also disclosed is a corrosion inhibiting heat transfer fluid, the heat 10 transfer fluid having a conductivity of no more than or equal to 200 ~S/cm and comprising the disclosed corrosion inhibitor. Also provided is an assembly comprising an alternative power source and a heat transfer system in thermal communication with the alternative power source, the heat transfer system comprising the disclosed corrosion inhibiting heat transfer fluid. In addition, a method of making a corrosion inhibiting heat transfer fluid is disclosed wherein the disclosed corrosion inhibitor is added to heat transfer fluid having a conductivity of less than 200 ~S/cm.
L'invention concerne un inhibiteur de corrosion utilisable dans des fluides de transfert thermique dont la conductivité est inférieure à 200 ?S/cm. L'inhibiteur de corrosion comprend un composé d'azole et au moins un tensioactif à base de siloxane, une silice colloïdale ou leur mélange. L'invention concerne également un fluide de transfert thermique (10) inhibiteur de corrosion, qui présente une conductivité inférieure ou égale à 200 ?S/cm et comprend une source d'énergie alternative et un système de transfert thermique communiquant avec la source d'énergie alternative. Le système de transfert thermique comprend ledit fluide de transfert thermique inhibiteur de corrosion. L'invention concerne en outre un procédé de production d'un fluide de transfert thermique inhibiteur de corrosion, dans lequel l'inhibiteur de corrosion est ajouté au fluide de transfert thermique présentant une conductivité inférieure à 200 ?S/cm.
