Résumé

Brushes made of carbon fibres with a high thermal conductivity are inserted on the shell side of a heat exchanger to enhance the conductive heat transfer rates in phase-change materials. The experimental results show that the brushes essentially improve the heat exchange rate during the charge and discharge processes, even when the volume fractions of the fibres are about one percent. A three-dimensional model describing heat transfer in the heat exchanger was numerically solved. The model reliably predicts the experimental outlet fluid temperatures and the local temperatures in the composite.
