Studies on a model of a condenser with plates cooled by water with one and two coils are carried out. The results of the experimental determination of the heat transfer coefficient with two cooling coils are used as a basis for calculating the electrothermal capacitors with a paper-oil dielectric and foil sheets. The calculated values of the heat transfer coefficient were obtained on the basis of the similarity theory with application of the Nusselt, Reynolds and Prandtl criteria. The experimental data of the heat transfer coefficient obtained on the basis of a model with two cooling coils are in good agreement with the calculated value of the heat transfer coefficient .
