Abstract
Apparatus and method for thermally discharging a heat storage accumulator containing a fusible storage substance the density of which is greater in the solid state than in the liquid state where the apparatus has means for creating a fluid vortex of the storage substance and scraper means for scraping crystallized storage substance off a heat sink portion of the accumulator such that crystallized storage substance is removed from the heat sink and transferred to the periphery of the accumulator.
Claims7
Apparatus for thermally discharging a heat storage accumulator containing a fusible storage substance the density of which in the solid state is larger than in the liquid state, characterized in that the accumulator has a heat transfer component located at the center of the accumulator, a heat exchange component located at the bottom of the accumulator and through which a fluid heat carrier is conducted and where the heat exchange component is subdivided by an intermediate wall into two chambers which intercommunicate along the periphery of the component, and means for producing an angular motion of the storage substance in its liquid state around said heat transfer component.
Apparatus for thermally discharging a heat storage accumulator where said accumulator has a heat sink portion at its center and contains a meltable heat storage substance which in its solid state has a higher density than in its liquid state, said apparatus comprising rotatable scraper means for contacting and removing crystallized storage material from the surface of said heat sink portion and for imparting a vortex motion to said heat storage substance in its fluid state whereby crystallized portions of said heat storage substance removed from said heat sink surfaces are conveyed by centrifugal forces to an inner periphery of said accumulator.
A method of thermally discharging heat from a heat storage accumulator having a heat sink portion therein and which contains a molten heat storage substance having a greater density in its solidified state than in its molten state, comprising the steps of crystallizing the storage substance on said heat sink portion, scraping said heat sink portion to remove the crystals therefrom and imparting a vortex motion to the molten storage substance whereby crystallized portions of the storage substance are moved by centrifugal forces radially outwardly and away from said heat sink portion.
