Abstract

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.
