Abstract: A device for the intermediate storage of thermal energy and to a system comprising a plurality of such devices is provided. The device has a solids store and a pipe system, which is formed of individual pipes and runs through the solids store and through which an energy carrier medium flows. In order to be able to quickly and uniformly charge the solids store with thermal energy or discharge thermal energy therefrom, heat conducting elements are provided, each forming heat transmission regions with the individual pipes and each extending into the regions of the solids store that are free of individual pipes. The heat conducting elements also have a higher heat conductivity than the solids store.
