Abstract
A heat store comprises heat-storage bodies for storing thermal energy, a housing, in which the heat-storage bodies are accommodated; and at least one line for a heat-transfer fluid, in order to feed thermal energy to the heat-storage bodies and/or carry it away from the heat-storage bodies. Each of the heat-storage bodies comprises a metal rail of an elongated form, the cross-section of which has a web between widened ends.
Claims20
A heat store comprising:
- heat-storage bodies for storing thermal energy;
- a housing in which the heat-storage bodies are received;
- and
- at least one conduit for a heat-transfer fluid in order to conduct thermal energy to and/or away from the heat-storage bodies;
- wherein each of the heat-storage bodies includes a metallic rail with an elongated shape, a cross-section of which comprises a web between wider ends, and
- wherein in cross-section one of the wider ends forms a base and another of the wider ends forms a rail head which is directly joined to the web and which has a width that is greater than a width of the web and smaller than a width of the base.

A method for operating a heat store,
- in which heat-storage bodies for storing thermal energy are received in a housing,
- wherein thermal energy is conducted to the heat-storage bodies and/or away from the heat-storage bodies with a heat-transfer fluid,
- wherein each of the heat-storage bodies includes a metallic rail with an elongated shape, a cross-section of which comprises a web between wider ends,
- wherein two separately conducted heat-transfer fluids are provided for conducting heat to the heat-storage bodies and for conducting heat away from the heat-storage bodies,
- wherein one of the heat-transfer fluids is conducted in pipe conduits between the rails, and
- wherein the other heat-transfer fluid is either conducted freely along the rails or in other pipe conduits between the rails.
