Abstract

Die Erfindung betrifft eine Wärmespeicheranordnung (10) zur Speicherung und/oder Übertragung von mittels elektromagnetischer Induktion erzeugter Wärme, umfassend einen Speicherraum (14) mit einem induktiv erwärmbaren Speichermaterial (12) und einer ersten Strömungsführung (24) zur Leitung von Wärmeträgermedium (16) in thermischem Kontakt zu dem Speichermaterial (12) von einer Eintrittsseite (34) zu einer Austrittsseite (36) und eine Induktoranordnung (40) mit einer um den Speicherraum (14) angeordneten Induktorvorrichtung (42) zur Erwärmung des Speichermaterials (12). Eine erhöhte Effizienz ist dadurch erreichbar, dass das Speichermaterial (12) in Form zumindest eines Einsatzelements (13) vorliegt, welches ein elektrisch leitfähiges, keramisches Material umfasst oder daraus gebildet ist und als erste Strömungsführung (24) zumindest einen von dem Wärmeträgermedium (16) durchströmbaren Strömungspfad (54) aufweist, wobei ein spezifischer Hohlraumanteil und/oder eine spezifische Wärmeübertragungsfläche zwischen dem zumindest einen Strömungspfad (54) und dem Speichermaterial (12) innerhalb des Einsatzelements (13) in radialer Richtung nach außen hin zunehmenThe invention relates to a heat storage arrangement (10) for storing and/or transferring heat generated by electromagnetic induction, comprising a storage space (14) with an inductively heatable storage material (12) and a first flow guide (24) for conducting heat transfer medium (16). thermal contact with the storage material (12) from an entry side (34) to an exit side (36) and an inductor arrangement (40) with an inductor device (42) arranged around the storage space (14) for heating the storage material (12). Increased efficiency can be achieved in that the storage material (12) is in the form of at least one insert element (13), which comprises or is formed from an electrically conductive ceramic material and, as a first flow guide (24), at least one of the heat transfer medium (16) through which flow path (54) can flow, wherein a specific cavity proportion and / or a specific heat transfer surface between the at least one flow path (54) and the storage material (12) within the insert element (13) increase in the radial direction outwards
