Latent heat store has outside surfaces of heat exchanger and/or inside surface of container for heat storage medium provided with sharp edges and/or points

摘要

The latent heat store (1) has a container (2) filled with a salt hydrate as the heat storage medium, used for heating or cooling a secondary medium via a heat exchanger (5) having a number of relatively spaced heat conduction plates, in thermic contact with the secondary medium. The outside surfaces of the heat exchanger and/or the inside surface of the container, in contact with the storage medium, have sharp edges and/or points, e.g. provided by tongues bent out from the surface of the heat exchanger plates
