Abstract

A simulation model of a liquid cooling system for medium- and high-power frequency converters using a heater as a heat exchanger is presented. A recalculation of the operating characteristics of the heat exchanger and the cooling system was performed with a change in the type of coolant. The error of the developed model based on the calculation results of the water temperature was 4.96%, and the air-temperature error was 5.25%. The proposed approach can be applied to recalculate the characteristics of the cooling system for other concentrations of aqueous ethylene glycol or propylene glycol solutions, as well as for other coolants.
