Abstract
A heat storage device comprising a closed reservoir within which is positioned a flexible closed container of smaller volume. The flexible container encloses a liquefiable heat-accumulating material; and the reservoir is provided with a heat-transport medium outside of the flexible container. The heat-transport medium always remains in the liquid phase and, upon solidification and shrinkage of the heat-accumulating material, fills the spaces thus formed between the flexible container and the reservoir wall in order to maintain adequate transfer of heat.
