Investigation of the intensification of heat exchange by spherical protrusions for a paraffin heat accumulator

\nThe article presents the results of experiments on charging and discharging a paraffin heat accumulator with different heat exchange surfaces. The purpose of the work was to test the efficiency of the heat accumulator by using a heat exchanger with spherical protrusions. The work uses data obtained during the experiments. In the course of the study, results were obtained that allow us to evaluate the positive effect of spherical protrusions on the operating cycle of a heat accumulator.\n
