In a heat storage device which utilizes the latent heat of fusion of a storage mass, the specific gravity of a heat carrier liquid is sufficiently different from that of the molten storage mass which is substantially immiscible with the liquid, for layers to be formed, and the rotor of a pump or mixer is so arranged in a layer of the liquid that a vortex is formed, whereby a mixture of the molten mass and the carrier liquid is sucked up by it. The mass is diminuted into small spheres and the heat exchange between the latter and the carrier liquid is intensified.

A heat storage device having a storage vessel, a fluid flow circuit external to and in fluid communication with said vessel, a heat storage mass in said vessel adapted to store heat in the course of its transition from a solid to a molten state, and a heat carrier liquid substantially immiscible with said storage mass disposed in said vessel for circulation through said vessel and said circuit and having a specific gravity different from the specific gravity of the storage mass when in the molten state; the improvement comprising in having a pump including a rotor positioned in said vessel to circulate heat carrier liquid through said circuit and drive means for said rotor whereby when said rotor is driven during heat discharge of the device, a mixture of said molten storage mass and said heat carrier liquid is sucked into said pump where said rotor reduces the molten storage mass into a plurality of small droplets which solidify upon transferring their heat to said heat carrier liquid and whereby said solidified droplets are moved by gravity and centrifugal forces imparted by said rotor away from said rotor towards the sides of said vessel.
